# Alpine configuration file
#
# This file sets the configuration options used by Alpine and PC-Alpine. These
# options are usually set from within Alpine or PC-Alpine. There may be a
# system-wide configuration file which sets the defaults for some of the
# variables. On Unix, run alpine -conf to see how system defaults have been set.
# For variables that accept multiple values, list elements are separated by
# commas. A line beginning with a space or tab is considered to be a
# continuation of the previous line. For a variable to be unset its value must
# be blank. To set a variable to the empty string its value should be "".
# You can override system defaults by setting a variable to the empty string.
# Lines beginning with "#" are comments, and ignored by Alpine.

CCIR493 Selcall

HF Selcall Experiments

Background

I became interested in HF selcall when I was looking for a way of setting up impromptu QSOs with specific stations, for doing tests etc., without the need for listening by ear for calls. Various ideas were considered for controlling an audio mute, and alerting the operator, on HF, but nothing seemed appropriate (CTCSS, DTMF etc) until I stumbled on CCIR493 HF Selcall, specifically designed to cope with conditions on the HF bands.

The protocol was familiar, as it's very similar (but slightly simpler) than GMDSS DSC. This led to more reading and research. CCIR493 is widely used in Land Mobile HF SSB in Australia and in other countries which use HF SSB as a communications method. It seems largely unused in Europe. In Australia it is used on the networks set up to assist 4WD outback travellers, with Selcall used to initiate contact with the various base stations.

Selcall's beacon and 99 beacon functions can be used to check if a particular station is reachable before attempting a voice call.

This seemed ideal…. down the rabbit hole of HF Selcall…..

Basic details

CCIR493 HF Selcall is a predecessor to GMDSS DSC used in Marine Radio.

Two Tone FSK with 170Hz shift
100baud signalling rate
Tone frequencies 1700 = 0, 1870 = 1 (tone centre = 1785)
- compare with DSC: 1615 = 1, 1785 = 0 (tone centre = 1700, inverted shift)
Symbols are 10-bit words, 7 bit + 3 parity bits
Dotting pre-amble of alternating 1010….. 2 to 20 seconds depending on expected scan-group size
Same “symbol repeat after 4” RX/DX interleaving as DSC
Same phasing sequence as DSC
No overall Error Check Sum, unlike DSC

At its simplest a selcall transmission can be either:

Directed call to a specific address
1. Selcall = send a revertive signal over the air AND alert the remote operator. The FMT symbol = 120
2. Directed-Beacon = send revertive signal over the air, but do not alert remote operator. The FMT symbol = 123
99-beacon call to a group of addresses = all stations send revertive signal over the air, but do not alert remote operator. The 99-beacon call is a special form of a directed selcall, with the FMT symbol of 120 and the final two digits of the destination address = 99. Receiving decoders understand to treat the call as a special type of beacon call despite the FMT being 120 (Selcall)

The directed-beacon to a specific address will confirm if that station is reachable, without disturbing the operator.

The 99-beacon call confirms whether any station in the group are reachable - the group is “any station with the first two digits matching”. The address used for the 99-beacon call is XX99, where XX is the leading digits of the desired group. For example, a group stations 3610, 3602, 3603, 3654 would all respond to a 99-beacon call addressed to 3699

Jenal SC2 Mic

HF Selcall is widely used in Australia, and there is a large market for add-on Selcall devices (to convert non-selcall radios) there. One manufacturer of Selcall equipment is JENAL.

At the time of my first exploration of Selcall I found that the SC2 microphone seemed like the perfect solution. The SC2 had been out of production, but Jenal had just released a new batch and I bought TWO of them, allowing me to experiment in isolation, should I fail to find any other amateur stations suitably equipped.

SC2 Handbook

One SC2 microphone can be connected to a Xiegu G90 portable HF transceiver, capable of 20W pep, and the other SC2 can be connected to a home made 60m SSB transceiver, also capable of 20W PEP, at the main station.

Scanning

The SC2 is capable of controlling the transceiver to scan, waiting for incoming selcall dotting signals, when it will pause the scan to decode any selcall message and act upon it as appropriate. Scan will resume after a certain period. The simplest scanning method is to pulse the channel up or channel down line present on most ham-grade transceivers on the mic-connector and thus the radio will step through its memory channels looking for selcall signals.

Previous Selcall Activity

In previous periods of activity with Selcall I have managed a few contacts and QSOs. Mainly with two stations who were already equipped with Barrett or Codan radios which can use CCIR493 “out of the box”.

GM4WMM - with a Barrett 950. We successfully operated on a small set of predetermined channels in the 80m, 60m, 40m bands, scanning, and selecting the optimum channel using beacon calls.
F6EMT - with a Codan . Made several contacts on 20m, some of them while mobile, initiated as random Selcall QSOs.

For 2023 I hope to find some more Selcall-equipped stations willing to try some experiments.

Selcall Activity 2023

[✓ John Pumford-Green, 2023-04-30] ~~Attach SC2 to Xiegu G90~~
[✓ John Pumford-Green, 2023-04-30]~~Set up 60m homebrew radio & amplifier & attach SC2~~
[✓ John Pumford-Green, 2023-05-05]~~Install mobile whip on van for use with G90~~
[✓ John Pumford-Green, 2023-04-30]~~Make adaptor for IC-M710 to allow easy connection of SC2 in place of usual datamode interface, for access to more bands~~
Try to make contact with like minded experimenters for on-air tests

UPDATE — John Pumford-Green 30/04/23 16:57

When not otherwise engaged I'll leave my main station IC-M710 monitoring 14.343MHz or 18.163MHz with Selcall ID 3658. I may not be able to respond directly to any calls the Selcall will send revertives (at 50W) for successful selcall or beacon calls to 3658or for 99-beacon calls to 3699

For skeds please contact me by email - address at https://www.qrz.com/db/GM4SLV

I have re-enabled emails from the hf-link groups.io https://groups.io/g/hflink to see what's happening here - the only place where CCIR493 appears to be discussed/used.

Additional Software

urxvt

Configured vi ~/.Xdefaults

For Ranger icons use DejavuSansMono NFM:size=11:style=Book

A bug makes font rendering odd, with too much space between characters (kerning is wrong)

A fix is to put Xft.rgba: none into ~/.Xdefaults

Another fix is to put URxvt.letterSpace=-1 into ~/.Xdefaults

Here's the ~/.Xdefaults I use:

Some un-used lines are commented out, but might be useful in testing….

Xft.rgba: none
#Xft.hintstyle: hintfull
#URxvt.letterSpace:-1
 
Xcursor.size:10
#URxvt.skipBuiltinGlyphs: true
URxvt.scrollBar: false
URxvt.boldFont: 
#URxvt.font: xft:DejaVuSansMono:style=Book:size=11

Ranger

Image Previews: /etc/ranger/config/rc.conf :

set preview_images true

set preview_images_method w3m

Draw borders round segments of display /etc/ranger/config/rc.conf :
```
set draw_borders both
```
Icons following instructions here: https://github.com/alexanderjeurissen/ranger_devicons
- /etc/ranger/config/rc.conf :
```
default_linemode devicons
```
Font for icons : https://github.com/ryanoasis/nerd-fonts/releases/download/v2.2.2/DejaVuSansMono.zip
- unzipped into : ~/.fonts
- font cache re-built with
```
fc-cache -fv
```
Use Lxterminal - handles icons and image previews (st is poor for image previews)
commands for exracting and creating compressed archives (zip, tar, tar.gz etc) from here https://wiki.archlinux.org/title/ranger#Archives
- added both python snippets to /etc/ranger/config/commands.py
- added keybindings to /etc/ranger/config/rc.conf
```
 
map ,n console compress 
map ,m compress temp.zip
map ,e console extract_here 
```
- extract a zip/tar/tar.gz by the keystroke ,e
- create an automatically named temp.zip archive by selecting the files (Space) and then ,m
- create a named archive of your choice ,n your_archive_name.[tar|zip|tar.gz]

GM4SLV Allstar 2025

New explorations into Allstar and Bridging

This was an initial experiment, I've used what I learned to set up a bigger system (still under development) and described here : Explorations

Hardware

Platform	Rapsberry Pi
Interface	CM108 Soundcard - modified
Radio	FT-1500M
Frequency	144.9125MHz
Allstar Node	48148
Dashboards	http://gm4slv.plus.com:42110/

DVSwitch Bridging

To investigate the bridging of Allstar analogue nodes and DMR I installed DVSwitch on the Allstar node.

Instructions here: ASL to DMR Bridge

The first part is easy, modifying a working Allstar node to add the private node and the USRP channel driver that will be used for the connection to the bridging.

My configs

#includeifexists custom/extensions.conf

The next bit was more tricky on an old Debian Buster ASL Beta image that hadn't been updated/upgraded in a long time….

Installing DVswitch

Installing DVSwitch was a bit convoluted, as my old version of the ASL Beta 2.0.0 wasn't up to date… and needed some work to add necessary APT gpg keys, and adding the dvswitch repository.

apt-get update –allow-releaseinfo-change to accept the release name change

Adding DVSwitch repository keys

As root :

apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys 0E98404D386FA1D9
 
apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys 6ED0E7B82643E131
 
curl -s http://apt.allstarlink.org/repos/repo_signing.key | apt-key add - && apt update
 
wget http://dvswitch.org/buster
 
chmod +x buster
 
./buster
 
apt-get update
 
apt-get install dvswitch

Configuring DVSwitch

The changes were made to the existing asterisk configs, as per the pdf document, then DVSwitch was installed, and then the pdf document was followed again to make the necessary configs to:

/opt/Analog_Bridge/Analog_Bridge.ini

and

/opt/MMDVM_Bridge/MMDVM_Bridge.ini

everything seemed to work okay - although there I think one of the UDP ports was initially wrong for the USRP traffic in Analog_Bridge.ini and I had to double check by looking in

/etc/asterisk/rpt.conf

[1999]
rxchannel = USRP/127.0.0.1:34001:31001

and setting Analog_Bridge.ini to match:

[USRP]
address = 127.0.0.1              
txPort = 31001                        
rxPort = 34001

Testing

I initially set the MMDVM_Bridge to connect to Brandmeister and Analog_Bridge to send traffic to TG2354429 (an ad hoc TG with my DMR ID).

in the asterisk CLI issue the command to link the main node 48148 with the internal private node 1999 to complete the bridge:

rpt cmd 2100 ilink 3 1999

transmit on the VHF FM input to the Gateway and listen on a DMR radio via my DMR hotspot connected to Brandmeister TG2354429 and the DMR radio sprang into life with my DMR ID….

transmit on the DMR radio, via the hotspot to Brandmeister and the VHF FM handheld carried the audio from the DMR radio.

I also tried setting MMDVM_Bridge to connect to DVS-Ph F and used the Options=TS2_1=842 to set TG842 as static. Setting Analog_Bridge to use TG 842 and once more the traffic was bi-directional Allstar ↔ DMR

So Far So Good

To boost the audio via the bridge

Analog_Bridge.ini to change from AUDIO_UNITY to AUDIO_USE_GAIN

[USRP]
address = 127.0.0.1                     
txPort = 31001                         
rxPort = 34001                       
usrpAudio = AUDIO_USE_GAIN            
usrpGain = 3                        
;usrpAGC = -20,10,100                 
tlvAudio = AUDIO_USE_GAIN                
tlvGain = 0.35

I set the various DVSwitch things to be enabled or disabled:

systemctl enable asterisk
systemctl enable analog_bridge
systemctl disable md380-emu
systemctl enable mmdvm_bridge

Later I found the other bridges available (P25, YSF, NXDN etc) were running, but not configured, so I used systemctl to disable them.

Allmon2 / supermon

I added the new node 1999 to allmon2 and supermon, so I can control/monitor the bridging via the web.

/var/www/html/allmon2/allmon.ini.php

Formatting Syntax

anonymous@undisclosed.example.com (Anonymous) — Tue, 04 Mar 2025 06:44:15 +0000

Formatting Syntax

DokuWiki supports some simple markup language, which tries to make the datafiles to be as readable as possible. This page contains all possible syntax you may use when editing the pages. Simply have a look at the source of this page by pressing “Edit this page”. If you want to try something, just use the playground page. The simpler markup is easily accessible via quickbuttons, too.

Basic Text Formatting

DokuWiki supports bold, italic, underlined and monospaced texts. Of course you can combine all these.

DokuWiki supports **bold**, //italic//, __underlined__ and ''monospaced'' texts.
Of course you can **__//''combine''//__** all these.

You can use _subscript and ^superscript, too.

You can use <sub>subscript</sub> and <sup>superscript</sup>, too.

You can mark something as ~~deleted~~ as well.

You can mark something as <del>deleted</del> as well.

Paragraphs are created from blank lines. If you want to force a newline without a paragraph, you can use two backslashes followed by a whitespace or the end of line.

This is some text with some linebreaks
Note that the two backslashes are only recognized at the end of a line
or followed by
a whitespace \\this happens without it.

This is some text with some linebreaks\\ Note that the
two backslashes are only recognized at the end of a line\\
or followed by\\ a whitespace \\this happens without it.

You should use forced newlines only if really needed.

Links

DokuWiki supports multiple ways of creating links.

External

External links are recognized automagically: http://www.google.com or simply www.google.com - You can set the link text as well: This Link points to google. Email addresses like this one: andi@splitbrain.org are recognized, too.

DokuWiki supports multiple ways of creating links. External links are recognized
automagically: http://www.google.com or simply www.google.com - You can set
link text as well: [[http://www.google.com|This Link points to google]]. Email
addresses like this one: <andi@splitbrain.org> are recognized, too.

Internal

Internal links are created by using square brackets. You can either just give a pagename or use an additional link text.

Internal links are created by using square brackets. You can either just give
a [[pagename]] or use an additional [[pagename|link text]].

Wiki pagenames are converted to lowercase automatically, special characters are not allowed.

You can use namespaces by using a colon in the pagename.

You can use [[some:namespaces]] by using a colon in the pagename.

For details about namespaces see namespaces.

Linking to a specific section is possible, too. Just add the section name behind a hash character as known from HTML. This links to this Section.

This links to [[syntax#internal|this Section]].

Notes:

Links to existing pages are shown in a different style from nonexisting ones.
DokuWiki does not use CamelCase to automatically create links by default, but this behavior can be enabled in the config file. Hint: If DokuWiki is a link, then it's enabled.
When a section's heading is changed, its bookmark changes, too. So don't rely on section linking too much.

Interwiki

DokuWiki supports Interwiki links. These are quick links to other Wikis. For example this is a link to Wikipedia's page about Wikis: Wiki.

DokuWiki supports [[doku>Interwiki]] links. These are quick links to other Wikis.
For example this is a link to Wikipedia's page about Wikis: [[wp>Wiki]].

Windows Shares

Windows shares like this are recognized, too. Please note that these only make sense in a homogeneous user group like a corporate Intranet.

Windows Shares like [[\\server\share|this]] are recognized, too.

Notes:

For security reasons direct browsing of windows shares only works in Microsoft Internet Explorer per default (and only in the “local zone”).
For Mozilla and Firefox it can be enabled through different workaround mentioned in the Mozilla Knowledge Base. However, there will still be a JavaScript warning about trying to open a Windows Share. To remove this warning (for all users), put the following line in conf/lang/en/lang.php (more details at localization):
conf/lang/en/lang.php
```
<?php
/**
 * Customization of the english language file
 * Copy only the strings that needs to be modified
 */
$lang['js']['nosmblinks'] = '';
```

Image Links

You can also use an image to link to another internal or external page by combining the syntax for links and images (see below) like this:

[[http://php.net|{{wiki:dokuwiki-128.png}}]]

Please note: The image formatting is the only formatting syntax accepted in link names.

The whole image and link syntax is supported (including image resizing, internal and external images and URLs and interwiki links).

Footnotes

You can add footnotes ¹⁾ by using double parentheses.

You can add footnotes ((This is a footnote)) by using double parentheses.

Sectioning

You can use up to five different levels of headlines to structure your content. If you have more than three headlines, a table of contents is generated automatically – this can be disabled by including the string ~~NOTOC~~ in the document.

Headline Level 3

Headline Level 4

Headline Level 5

==== Headline Level 3 ====
=== Headline Level 4 ===
== Headline Level 5 ==

By using four or more dashes, you can make a horizontal line:

Media Files

You can include external and internal images, videos and audio files with curly brackets. Optionally you can specify the size of them.

Real size:

Resize to given width:

Resize to given width and height²⁾:

Resized external image:

Real size:                        {{wiki:dokuwiki-128.png}}
Resize to given width:            {{wiki:dokuwiki-128.png?50}}
Resize to given width and height: {{wiki:dokuwiki-128.png?200x50}}
Resized external image:           {{https://www.php.net/images/php.gif?200x50}}

By using left or right whitespaces you can choose the alignment.

{{ wiki:dokuwiki-128.png}}
{{wiki:dokuwiki-128.png }}
{{ wiki:dokuwiki-128.png }}

Of course, you can add a title (displayed as a tooltip by most browsers), too.

{{ wiki:dokuwiki-128.png |This is the caption}}

For linking an image to another page see Image Links above.

Supported Media Formats

DokuWiki can embed the following media formats directly.

Image	`gif`, `jpg`, `png`
Video	`webm`, `ogv`, `mp4`
Audio	`ogg`, `mp3`, `wav`
Flash	`swf`

If you specify a filename that is not a supported media format, then it will be displayed as a link instead.

By adding ?linkonly you provide a link to the media without displaying it inline

{{wiki:dokuwiki-128.png?linkonly}}

dokuwiki-128.png This is just a link to the image.

Fallback Formats

Unfortunately not all browsers understand all video and audio formats. To mitigate the problem, you can upload your file in different formats for maximum browser compatibility.

For example consider this embedded mp4 video:

{{video.mp4|A funny video}}

When you upload a video.webm and video.ogv next to the referenced video.mp4, DokuWiki will automatically add them as alternatives so that one of the three files is understood by your browser.

Additionally DokuWiki supports a “poster” image which will be shown before the video has started. That image needs to have the same filename as the video and be either a jpg or png file. In the example above a video.jpg file would work.

Lists

Dokuwiki supports ordered and unordered lists. To create a list item, indent your text by two spaces and use a * for unordered lists or a - for ordered ones.

This is a list
The second item
- You may have different levels
Another item

The same list but ordered
Another item
1. Just use indention for deeper levels
That's it

  * This is a list
  * The second item
    * You may have different levels
  * Another item

  - The same list but ordered
  - Another item
    - Just use indention for deeper levels
  - That's it

Also take a look at the FAQ on list items.

Text Conversions

DokuWiki can convert certain pre-defined characters or strings into images or other text or HTML.

The text to image conversion is mainly done for smileys. And the text to HTML conversion is used for typography replacements, but can be configured to use other HTML as well.

Text to Image Conversions

DokuWiki converts commonly used emoticons to their graphical equivalents. Those Smileys and other images can be configured and extended. Here is an overview of Smileys included in DokuWiki:

Text to HTML Conversions

Typography: DokuWiki can convert simple text characters to their typographically correct entities. Here is an example of recognized characters.

→ ← ↔ ⇒ ⇐ ⇔ » « – — 640×480 © ™ ® “He thought 'It's a man's world'…”

-> <- <-> => <= <=> >> << -- --- 640x480 (c) (tm) (r)
"He thought 'It's a man's world'..."

The same can be done to produce any kind of HTML, it just needs to be added to the pattern file.

There are three exceptions which do not come from that pattern file: multiplication entity (640×480), 'single' and “double quotes”. They can be turned off through a config option.

Quoting

Some times you want to mark some text to show it's a reply or comment. You can use the following syntax:

I think we should do it

> No we shouldn't

>> Well, I say we should

> Really?

>> Yes!

>>> Then lets do it!

I think we should do it

No we shouldn't

Well, I say we should

Really?

Yes!

Then lets do it!

Tables

DokuWiki supports a simple syntax to create tables.

Heading 1	Heading 2	Heading 3
Row 1 Col 1	Row 1 Col 2	Row 1 Col 3
Row 2 Col 1	some colspan (note the double pipe)
Row 3 Col 1	Row 3 Col 2	Row 3 Col 3

Table rows have to start and end with a | for normal rows or a ^ for headers.

^ Heading 1      ^ Heading 2       ^ Heading 3          ^
| Row 1 Col 1    | Row 1 Col 2     | Row 1 Col 3        |
| Row 2 Col 1    | some colspan (note the double pipe) ||
| Row 3 Col 1    | Row 3 Col 2     | Row 3 Col 3        |

To connect cells horizontally, just make the next cell completely empty as shown above. Be sure to have always the same amount of cell separators!

Vertical tableheaders are possible, too.

	Heading 1	Heading 2
Heading 3	Row 1 Col 2	Row 1 Col 3
Heading 4	no colspan this time
Heading 5	Row 2 Col 2	Row 2 Col 3

As you can see, it's the cell separator before a cell which decides about the formatting:

|              ^ Heading 1            ^ Heading 2          ^
^ Heading 3    | Row 1 Col 2          | Row 1 Col 3        |
^ Heading 4    | no colspan this time |                    |
^ Heading 5    | Row 2 Col 2          | Row 2 Col 3        |

You can have rowspans (vertically connected cells) by adding ::: into the cells below the one to which they should connect.

Heading 1	Heading 2	Heading 3
Row 1 Col 1	this cell spans vertically	Row 1 Col 3
Row 2 Col 1		Row 2 Col 3
Row 3 Col 1		Row 2 Col 3

Apart from the rowspan syntax those cells should not contain anything else.

^ Heading 1      ^ Heading 2                  ^ Heading 3          ^
| Row 1 Col 1    | this cell spans vertically | Row 1 Col 3        |
| Row 2 Col 1    | :::                        | Row 2 Col 3        |
| Row 3 Col 1    | :::                        | Row 2 Col 3        |

You can align the table contents, too. Just add at least two whitespaces at the opposite end of your text: Add two spaces on the left to align right, two spaces on the right to align left and two spaces at least at both ends for centered text.

Table with alignment
right	center	left
left	right	center

This is how it looks in the source:

Note: Vertical alignment is not supported.

No Formatting

If you need to display text exactly like it is typed (without any formatting), enclose the area either with <nowiki> tags or even simpler, with double percent signs %%.

This is some text which contains addresses like this: http://www.splitbrain.org and **formatting**, but nothing is done with it. The same is true for //__this__ text// with a smiley ;-).

<nowiki>

</nowiki>
The same is true for %%//__this__ text// with a smiley ;-)%%.

Code Blocks

You can include code blocks into your documents by either indenting them by at least two spaces (like used for the previous examples) or by using the tags <code> or <file>.

This is text is indented by two spaces.

This is preformatted code all spaces are preserved: like              <-this

This is pretty much the same, but you could use it to show that you quoted a file.

Those blocks were created by this source:

  This is text is indented by two spaces.

<code>
This is preformatted code all spaces are preserved: like              <-this
</code>

<file>
This is pretty much the same, but you could use it to show that you quoted a file.
</file>

Syntax Highlighting

DokuWiki can highlight sourcecode, which makes it easier to read. It uses the GeSHi Generic Syntax Highlighter – so any language supported by GeSHi is supported. The syntax uses the same code and file blocks described in the previous section, but this time the name of the language syntax to be highlighted is included inside the tag, e.g. <code java> or <file java>.

/**
 * The HelloWorldApp class implements an application that
 * simply displays "Hello World!" to the standard output.
 */
class HelloWorldApp {
    public static void main(String[] args) {
        System.out.println("Hello World!"); //Display the string.
    }
}

The following language strings are currently recognized: 4cs 6502acme 6502kickass 6502tasm 68000devpac abap actionscript3 actionscript ada aimms algol68 apache applescript apt_sources arm asm asp asymptote autoconf autohotkey autoit avisynth awk bascomavr bash basic4gl batch bf biblatex bibtex blitzbasic bnf boo caddcl cadlisp ceylon cfdg cfm chaiscript chapel cil c_loadrunner clojure c_mac cmake cobol coffeescript c cpp cpp-qt cpp-winapi csharp css cuesheet c_winapi dart dcl dcpu16 dcs delphi diff div dos dot d ecmascript eiffel email epc e erlang euphoria ezt f1 falcon fo fortran freebasic freeswitch fsharp gambas gdb genero genie gettext glsl gml gnuplot go groovy gwbasic haskell haxe hicest hq9plus html html4strict html5 icon idl ini inno intercal io ispfpanel java5 java javascript jcl j jquery julia kixtart klonec klonecpp kotlin latex lb ldif lisp llvm locobasic logtalk lolcode lotusformulas lotusscript lscript lsl2 lua m68k magiksf make mapbasic mathematica matlab mercury metapost mirc mk-61 mmix modula2 modula3 mpasm mxml mysql nagios netrexx newlisp nginx nimrod nsis oberon2 objc objeck ocaml-brief ocaml octave oobas oorexx oracle11 oracle8 oxygene oz parasail parigp pascal pcre perl6 perl per pf phix php-brief php pic16 pike pixelbender pli plsql postgresql postscript povray powerbuilder powershell proftpd progress prolog properties providex purebasic pycon pys60 python qbasic qml q racket rails rbs rebol reg rexx robots roff rpmspec rsplus ruby rust sas sass scala scheme scilab scl sdlbasic smalltalk smarty spark sparql sql sshconfig standardml stonescript swift systemverilog tclegg tcl teraterm texgraph text thinbasic tsql twig typoscript unicon upc urbi uscript vala vbnet vb vbscript vedit verilog vhdl vim visualfoxpro visualprolog whitespace whois winbatch wolfram xbasic xml xojo xorg_conf xpp yaml z80 zxbasic

There are additional advanced options available for syntax highlighting, such as highlighting lines or adding line numbers.

Downloadable Code Blocks

When you use the <code> or <file> syntax as above, you might want to make the shown code available for download as well. You can do this by specifying a file name after language code like this:

<file php myexample.php>
<?php echo "hello world!"; ?>
</file>

myexample.php

<?php echo "hello world!"; ?>

If you don't want any highlighting but want a downloadable file, specify a dash (-) as the language code: <code - myfile.foo>.

RSS/ATOM Feed Aggregation

DokuWiki can integrate data from external XML feeds. For parsing the XML feeds, SimplePie is used. All formats understood by SimplePie can be used in DokuWiki as well. You can influence the rendering by multiple additional space separated parameters:

Parameter	Description
any number	will be used as maximum number items to show, defaults to 8
reverse	display the last items in the feed first
author	show item authors names
date	show item dates
description	show the item description. All HTML tags will be stripped
nosort	do not sort the items in the feed
n[dhm]	refresh period, where d=days, h=hours, m=minutes. (e.g. 12h = 12 hours).

The refresh period defaults to 4 hours. Any value below 10 minutes will be treated as 10 minutes. DokuWiki will generally try to supply a cached version of a page, obviously this is inappropriate when the page contains dynamic external content. The parameter tells DokuWiki to re-render the page if it is more than refresh period since the page was last rendered.

By default the feed will be sorted by date, newest items first. You can sort it by oldest first using the reverse parameter, or display the feed as is with nosort.

Example:

{{rss>http://slashdot.org/index.rss 5 author date 1h }}

Control Macros

Some syntax influences how DokuWiki renders a page without creating any output it self. The following control macros are availble:

Macro	Description
~~NOTOC~~	If this macro is found on the page, no table of contents will be created
~~NOCACHE~~	DokuWiki caches all output by default. Sometimes this might not be wanted (eg. when the <php> syntax above is used), adding this macro will force DokuWiki to rerender a page on every call

Radio Update - QRP etc

anonymous@undisclosed.example.com (Anonymous) — Tue, 07 Jul 2026 09:05:14 +0000

Radio Update - QRP etc

After setting up a basic station in the small “office” - just one rig and my keys - I decided to make a “real” hamshack with more radios, some tools, test equipment etc.

I added two shelves above the desk to hold radios, PSUs, 'scope, tools etc. I've now got a “one-desk shack” that can be used for operating on air and building & repairing equipment (on a small scale)

I found that the stock mic for my FT891 was faulty - the mic element is open-circuit - so I bought a Heil HMM fist mic and spent some time setting up the EQ for a reasonable “communications” quality audio. I'm not naturally a 'phone operator, so I'll not be having lots of “ragchew” QSOs, and “communications quality” is all I'm aiming for - to be audible - not quite as extreme as a Clansman but with enough HF emphasis, and enough compression to cut through the noise.

I though briefly about limiting myself to SSB for a few months, to get used to talking on the radio, but that's NEVER going to happen.

The QMX

Then I found a box with an unbuilt QRPLabs "QMX" kit! I'd bought it in August 2023, and hadn't built it. I have a QCX-mini for 40m and it's a great little radio, and I thought the QMX would be the next obvious step. Then I forgot about it.

So, on Saturday I got the box, opened it. Printed out the Assembly Manual. Watched Hans's You Tube video highlighting the pitfalls. And got started.

The first thing was to check if my early (Rev 1) board has the “Power Board Short” issue - and it did - so I got out my hot-air station and moved the MOSFET a mm or two to remove the short.

Then down to business…. building.

I did it all in one day, with the occasional break for food, dog walk, etc….. The most challenging thing was winding the 2 binocular ferrite transformers - the PA output transformer and the SWR brigge transformer. The “normal” toroid cores were all straightforward.

I built it for 9V operation (this determines the form of the PA output transformer).

I worked first time. Which is amazing given the small size and relatively dense component layout.

On a PSU set for 9V I get at least 5W on all bands. I made a string of 4 x 1N4001 diodes to drop ~2.4V and powered it from the normal shack supply. And used the handy config option “Limit PA Volts” to set a limit of 9.5V. This gives a comfortable 5W on all bands without any risk of overheating the finals etc.

I've used it on WSPR - both via WSJT-X and using the internal standalone WSPR Beacon mode.

I upgraded to the current beta firmware 1_04_002 and the main change seems to be the removal of the Beacon mode and its replacement with “Virtual U3S” - a mimic of the functionality of the U3S multi-function beacon TX. Currently only WSPR is supported - but the other modes will follow. This works well - and allows a “schedule” to change frequency / Mode etc on sequential TX periods.

Back to QRP CW

Then I had to try it on CW.

My first CW QSO was on 30m with Rob, OK7SX, on Wednesday 29th.

Last night I had 3 x CW QSOs : F/FK8IK (Mic nr Vichy), IK3/UY7LA (Alex, nr Venice) on 30m and the icing on the cake was a chat with Will GM0HKS on 40m.

Will was using a K2 at 5W, but did mention that he still has the “wee K1” - that's my old K1 that I built back in 2003. I sold it (and deeply regret doing so) and it ended up in Will's care. We've had a few QSOs over the years and he never fails to mention the “wee K1”.

The next step

I've been thinking about where I want to go with radio recently.

What actually gives me pleasure?

What can I do to avoid the aspects of the hobby that spoil it for me?

Building and using the QMX reminded me of the fun I got with I first built the “wee K1” in 2003.

I hadn't been active in the hobby for many years, my log book shows a couple of FM contacts in 2002 with locals on the repeater, and prior to that I was using Packet Radio in 1994, while still living in Huddersfield and working at Holme Moss. The last time I'd actually been on HF CW was while I was at UMIST, in 1985 using the club station.

I built the K1 in 2003 and went CW crazy!

The basic chronology :

pre-2003
- 1983 - first licensed as G4SLV, still at school. Used 10mFM and 2m CW before going away to University in 1984
- 1984 - 1988 - at UMIST, and active in the Radio Society. Used club station for HF CW, as well as 70cm ATV and “other” things
- 1988 - 1995 - not much radio - some Packet on 2m
- 1995 - moved to Wick. Some HF SWL using my old AR88D. No “ham” radio
- 1999 - moved to Shetland. Some 2m activity on local repeater. Some HF SWL with AR88D and AR7030.
August 2003 - K1 - 2 bands - 40m / 20m - lots of QSOs. A very active phase on the hobby on-the-air.
Some time in 2004 - K1 - added 4 band board & concentrated on 40/30/20
Some time in 2004 - IC706MK2G - all bands - 100W - K1 use still frequent - but the lure of 100W was strong for a while - plus digimodes (PSK31 etc)
November 2004 - 60m use began - mostly SSB - K1 still in use for QRP CW
2007 - K2 added to the shack
July 2007 - Start of 500kHz “experiment”. All HF working stopped and lots of time spent with MF - Sold K1 & K2 and IC706. Bought IC718
Jan 2009 - Back to HF, mix of QRO and QRP. Mostly CW, Some SSB and digimodes
Nov 2010 - Back to 500kHz, with some HF mixed in.
Jan 2011 - Back to HF

At some point during the MF phase I sold the K1 and K2.

From 2012 I spent most of my time on 60m using digimodes, mostly Olivia. I still dabbled on HF CW. Mostly QRO. Bought IC7200 to add to the Shack.

The three main phases were

QRP CW on 40m/20m with K1
500kHz CW (and some WSPR etc)
60m Digimodes

Looking at my logbooks I can tell that I really delved deeply into QRP CW with the K1. I worked many, many people in many, many places and had a lot of fun with such a simple little radio.

The K2 was fun to build, but it got little use - I remember preferring the “wee K1” to its big brother. The 500kHz experiment in 2007 intervened and pushed the QRP HF rigs to the side and they were sold to fund “more important” items.

On 60m I had a lot of fun, learning a lot about the propagation on the band, and about the different behaviour of the various digimodes.

I came back to HF CW a few times - but nothing sparked joy like those early times with the K1.

The future?

Building the QMX has shown me that it's possible to have fun building and then have more fun using simple QRP radios. And this might be the push I need to get back into QRP.

It's more challenging these days - as most people in urban environments have raised noise levels and struggle to hear “normal weak signals” - but there are still people actively using QRP, and only QRP, to fully enjoy the hobby.

If I can't work someone due to my weak signal, then so be it… move on… there'll always be someone else to work.

One area I've never tried is QRP SSB. So I've turned the power on my FT891 (the “SSB rig”) down to 10 watts. I'll give it a try some time. But once more my focus is back to CW. And now with an additional slant - QRP, and only QRP.

I'll write more as I explore.

My G-QRP Club membership number is 2377, dating back to around 1984…. so I've been at it a long time, in fits and starts.

LF15C - firmware for the DM15

anonymous@undisclosed.example.com (Anonymous) — Sun, 19 Apr 2026 20:20:12 +0000

←3rd Party Firmware

LF15C - firmware for the DM15

A 3rd Party Firmware for the DM15 family of calculators

Overview of LF15C

Full development history in HP Forum thread New firmware for the Swissmicros DM15L

LF15C is written by HP Museum Forum member jebedeo
It is a replacement firmware for the Swiss Micros DM15C & DM15L calculators.
- also runs on the original DM15 credit card version no longer in production
It is not an emulation or an exact simulation of the HP15C
It runs directly on the hardware without an emulation layer.
It is very much faster than the stock firmware
It has full-time complex number support
- including display of the full real & imaginary parts on the LCD together 3.345 +22.356 i
It has a 4-level stack with full-time 2-level display of X and Y
All the main HP15C functions are included with the exception of Matrix support

Installing LF15C

DM15L running V32 or earlier (Linux)

sudo lpc21isp LF15C_250408.hex /dev/ttyUSB0 115200 1200
Press hidden reset button
- firmware is flashed
press hidden reset button to start new firmware

DM15L running V33 or later (Linux)

This behaviour isn't consistent!

I've seen it be possible to flash and run LF15C directly after DM15 V34 with no problems.

I've also seen the problems described below, requiring downgrade to V32.

Just bear it in mind if you have problems starting LF15C after flashing it on top of V33-onwards

The new Swiss Micros firmware V33 changes the behaviour of the bootloader, and it appears to be impossible to flash 3rd party firmware when the calculator is running V33 or later.

The firmware appears to flash correctly, but on reset it will not start

The solution is to downgrade to V32 first, and then install LF15C

sudo lpc21isp DM15_M1B_32.hex /dev/ttyUSB0 115200 1200
press hidden reset button
- firmware is flashed
press hidden reset button to start V32 firmware
sudo lpc21isp LF15C_250408.hex /dev/ttyUSB0 115200 1200
press hidden reset button
- firmware is flashed
press hidden reset button to start new LF15C firmware

For installation using Windows

The Swiss Micros Voyager Update Tool will work to install LF15C
- Do not use the new Web Update tool
The same caveats regarding installation after using the Swiss Micros V33 apply
- First downgrade to V32
- Then flash with LF15C
You need to use the hidden reset button in all cases.

Using LF15C

Complex Numbers

The stack is permanently in complex mode and operates slightly differently to the stock HP15C

Making & manipulating a complex number

Press f I in normal mode to create & destroy a complex number from ⇔ to y and x on the stack.

Example (click to view)

Make a pure imaginary number by using fRe<>Im

Example (Click to view)

Rectangular and Polar modes for complex numbers

f →R and g→P do NOT to convert x and y stack levels between Rect and Polar values as in the HP15C
→R and →P are Mode Switching commands for the whole complex stack.
When in Polar mode ALL Complex numbers on the stack are in Magnitude / Angle format.
- The angle format can be Deg or Rad as appropriate

Example (click to view)

Arithmetic can be done in Rectangular or Polar mode.

Mode can be switched at any time - perhaps switching to Rectangular to enter a Rectangular format number, when working in Polar, and then switching back to Polar once it's been entered on the stack..
Intermediate calculations can be done whatever mode is current.
- this is unlike the HP15C, where complex arithmetic has to be done in Rectangular format - and Polar format numbers must be converted → R first.
To confirm the mode in use an annunciator P is always present when in Polar.
- No P means Rectangular mode is active.

Example (click to view)

Other features

Indirect addressing

Similar features to the standard HP15C, with differences due to increased Program Label numbers

Indirect Register pair I & (i)

Indirect Register pair I and (i) work in the usual way

Example (click to view)

Indirect Program Label addressing

As in the HP15C you can also indirectly address Program Labels using the contents of the I register to point to the label required.

The HP15C allowed 20 numerical Program Labels 0 - .9 which meant indirect addressing for Labels A - E was done by reference to 20 - 24 in Register I

LF15C has 100 numerical Program Labels so….

Store 00 - 99 in I to address numerical Program Labels 00 - 99

Store 100 - 104 I to address Program Labels A - E

Using GTO I or GSB I in a program will lead to a jump to the Program Label referred to by contents of Register I.

Changing Register I's contents (e.g. within a program) can then cause the execution of program to branch in different ways - this can be a very powerful mechanism!

Example (click to view)

Store 100 (for LBL A) in the indirect Register I

100STOI

Use the value stored in I as a Label indirectly by calling it from within a program.

LBL A is a small program to do a simple calculation (area of circle from radius held in x)

LBL B, which has the single command GTO I

Running LBL B fB actually runs the program in LBL A : GTO I is interpreted as GTO A.

LBL A
X^2
PI
*
RTN

LBL B
GTO I
RTN

Changing the contents of Register I will change where LBL B points to.

This allows you to make decisions and branches to different code communicated via the indirect register.

Storing 101 in Reg I and then running LBL B has the effect of an endless loop….. LBL B calls itself (indirectly via I=101)

Use R/S to interrupt the endless loop!

Using GTO I in LBL B means execution passes to LBL A and does not return to LBL B on completion.

Using GSB I in LBL B instead of GTO means that after running LBL A (via indirection) execution returns to LBL B and continues….

Indirect Program Line Number Addressing

Similar to the above, if the Indirect Register I contains a NEGATIVE number then a call to GTO I or GSB I will cause a branch to the absoloute Line Number referred to in I.

Example (Click to view)

0 Empty
1 LBL A
2 GTO I
5 RTN
6 LBL 88
8 X^2
9 PI
10 *
11 RTN
12 Empty

Storing 88 in Register I would make Program A branch to the Label 88 (line 6)

Storing -9 in Register I (9 CHS STO I) would make Program A branch to PI (at line 9) and bypass the X² instruction.

Line numbering isn't straightforward, as each instruction may use one or two line numbers depending on the instruction itself, so you have to be careful about which line you need to address.

And the rest

100 Storage Registers 00 - 99 are capable of storing Complex Numbers

Factorial / Gamma x! works on integer (positive), non-integer (positive and negative) and complex numbers

Program Mode shows human-readable text rather than HP15C op-codes
- 2-line display of Program being edited

Selection of logical tests can be done in usual HP15C fashion with TEST 0 - TEST 9
- Test can also be selected from a scrolling list of options after initially pressing gTEST with the choice being made via soft-keys & LCD Prompts

To run a program with a numeric label (i.e. other than LBL A → LBL E) press f LBL ##
- e.g. f LBL 88
- this is different than on the original HP15C where to run a label you used GSB##

In program mode, f CLEAR PREFIX places the runTime opCode in the program. runTime writes to x the program execution time once it's executed.

Deleting User Programs
- Delete a single program : f CLEAR PRGM followed by a label
- Delete ALL programs : f and long press CLEAR PRGM

FIX/SCI/ENG don't round numbers unless gRND is pressed.

fENGnn sets the number of significant digits as requested, UNLIKE the original HP15C where fENGn sets the significant digits to n + 1

There are 10 user flags, from 0 to 9.
- There are no LCD annunciators to show state, but flags can be set, cleared and tested for decision making in program branching

Long press GTO in program mode to access go to label feature (single press in run mode)
Long press GSB in program mode to access go to line number feature (single press in run mode)

When running a program step by step, a long press on SST doesn’t execute the current step.

Unused Keys
- f USER, gMEM, fDIM, fMATRIX and fRESULT are not implemented and don't do anything at the moment.

←AllStar Linking

Explorations

Digging Deeper into Allstar

I've seen a few examples of small networks and am interested in building up a mixed protocol system too.

Some examples that interested me:

Milnet http://milnet.io/ with Allstar connected nodes and a DMR bridge
- Allstar node status http://stats.allstarlink.org/nodeinfo.cgi?node=424611
W2YMM https://w2ymm.home.blog/allstar-howto/ with a group of connected gateways, repeaters and a bridge to DMR etc.
- This one was discovered by accident on Allstar's Portal I mistyped my own original base node ID (pre-NNX) 48148 as 48418 and found his system with lots of information on his blog

Adding more nodes

It's possible to have up to 10 individual Node IDs with a single Allstar node number, by using NNX to add a 6th digit to the base node number…

My Base Number is 48148 and I activated the NNX feature and created 3 nodes

481480
481481
481482

Since they are all behind a NAT firewall, sharing one public IP address the nodes must use different UDP ports. To make this possible I created 2 new Server instances on the Allstar Portal, one per node, and chose the UDP ports :

https://www.allstarlink.org/portal/servers.php

node481480 ⇒ UDP 4569
node481481 ⇒ UDP 4570
node481482 ⇒ UDP 4571

The choice of which server is used per node is chosen on the Node configuration page for each node, on the Allstar Portal

https://www.allstarlink.org/portal/nodes.php

Then I flashed new SD cards for the new nodes using the ASL 2.0.0 Beta 6 image I've used for the initial VHF Gateway node.

https://github.com/AllStarLink/ASL-Live-Build/releases/download/2.0.0-beta.6/asl-2.0.0-beta.6-kc1kcc-20210324-raspberrypi-armhf.img.zip

The config. for the original node had to be changed, to reflect the new node number 481480 versus 48148 which means editing (at least)

/etc/asterisk/rpt.conf
/etc/asterisk/iax.conf
/etc/asterisk.extensions.conf

To ensure each internal LAN node can find each other (can't rely on Allstar's DNS) it's necessary to add each one to the [nodes] stanza in each node's config file /etc/asterisk/rpt.conf using the appropriate IP and UDP port depending on which node is being configured.

; from the VHF Gateway node 481480
[nodes]
481480 = radio@127.0.0.1:4569/481480,NONE      

481481 = radio@192.168.21.241:4570/481481,NONE  

481482 = radio@192.168.21.242:4571/481482,NONE

I added the DVSwitch bridging to the hub node 481481 which is configured as radioless, I made a local/private node on that machine 1399 for this purpose.

All 3 nodes have supermon and this needed some configuration to make sure the Asterisk Manager ports were available on their external interfaces bindaddr = 0.0.0.0 and not just on the loopback bindaddr = 127.0.0.1

/etc/asterisk/manager.conf ⇒

;
; Asterisk Call Management support
;

; By default asterisk will listen on localhost only.
[general]
enabled = yes
port = 5038
bindaddr = 0.0.0.0

[admin]
secret = YOUR_MANAGER_PASSWORD
read = all,system,call,log,verbose,command,agent,user,config
write = all,system,call,log,verbose,command,agent,user,config

Port Forwarding

My ADSL router has the following port forwards to allow external incoming connections to be set up

UDP 4569 ⇒ 192.168.21.240 for the VHF Gateway / Echolink node
UDP 4570 ⇒ 192.168.21.241 for the DMR Bridge node
UDP 4571 ⇒ 192.168.21.242 for the Test Node
UDP 5198-5199 ⇒ 192.168.21.240 for Echolink client connections
TCP 42110 ⇒ 192.168.21.240 for the VHF Gateway/Echolink node's Dashboard
- http://gm4slv.plus.com:42110
TCP 42111 ⇒ 192.168.21.241 for the DMR Bridge node's Dashboard
- http://gm4slv.plus.com:42111
TCP 42112 ⇒ 192.168.21.242 for the Test node's Dashboard
- http://gm4slv.plus.com:42112

To allow the node numbers to be resolved to useful names tp display on the dashboards the script astdb.php should run nightly to maintain a lookup table.

The image came with several copies of astdb.php in different places, all updating a central data file /var/log/asterisk/astdb.txt. Which was confusing, as they all looked in different places for the file detailing private nodes.

Private Node Names

To allow private node numbers to appear as useful information, rather than not in database you first put the information in a file privatenodes.txt

1399|GM4SLV|Bridge to DMR|TGIF TG2354429
1398|GM4SLV|Bridge to DMR|TGIF TG2354435

and then the astdb.php script pulls it in, with all the other nodes downloaded from the web, but astdb.php must know where to find the privatenodes.txt file.

The easiest way is to run the astdb.php from the directory containing privatenodes.txt

and therefore it's the copy in /var/www/html/supermon/ that is used, since privatenodes.txt resides here too.

To automate the process the update is done nightly via /etc/cron.daily/allstar_helpers which was modified to point to the correct version of astdb.php

#!/bin/bash
 
 
# Get new allmon data daily
/var/www/html/supermon/astdb.php

Semi-automated Private Node descriptions

I've written a small bash script on the gateway node481480.local to make it easier to re-name the internal “private nodes” as they appear listed in Supermon
for this to work it's necessary to arrange public-key authentication on the nodes, with passwordless logins. But that's normal, anyway, no?

#!/bin/bash
 
NODE1=node481480.local
NODE2=node481481.local
NODE3=node481482.local
WEB=/var/www/html/supermon/
 
PRIVATE_NODES=/home/gm4slv/privatenodes.txt
 
 
sudo cp $PRIVATE_NODES $WEB
sudo $WEB/astdb.php
 
 
scp $PRIVATE_NODES gm4slv@$NODE2:
ssh $NODE2 'sudo cp /home/gm4slv/privatenodes.txt /var/www/html/supermon/ && /var/www/html/supermon/astdb.php'
 
 
scp $PRIVATE_NODES gm4slv@$NODE3:
ssh $NODE3 'sudo cp /home/gm4slv/privatenodes.txt /var/www/html/supermon/ && /var/www/html/supermon/astdb.php'

Just make changes to the privatenodes.txt file in my local directory on the gateway node481480 and then run

gm4slv@node481480:~$ ./update_private.sh
Success: astdb.txt 1422647 bytes

Success: astdb.txt 1422647 bytes

Favourites

to keep the favorites.ini file consistent on all nodes I've written a script that distributes a copy to all nodes
I edit the copy in my home directory on node481480 and run

./update_favorites.sh

#!/bin/bash
# update_favorites.sh
# a script to keep the supermon favorites.ini file synchronized on all nodes
 
NODE1=node481480.local

sudo cp $FAVORITES $WEB
 
scp $FAVORITES gm4slv@$NODE2:
ssh $NODE2 'sudo cp /home/gm4slv/favorites.ini /var/www/html/supermon/'
 
scp $FAVORITES gm4slv@$NODE3:
ssh $NODE3 'sudo cp /home/gm4slv/favorites.ini /var/www/html/supermon/'

Supermon : allmon.ini

The nodes monitored, and the menu to select them, and external websites, on each node's Supermon Dashboard is configured by allmon.ini

Here's the current version:

Node Callsigns instead of Numbers

To have the telemetry say the callsign of a connected node, instead of its node number, install the script write_node_callsigns_ulaw.sh

I put it in /usr/local/bin/ and run it via root's crontab each day - but via a wrapper script /usr/local/bin/update_names.sh that then deletes the ulaw sound file for my own nodes, as I don't want all of them to be announced as GM4SLV - I'd rather hear the actual node numbers:

#!/bin/bash
 
/usr/local/bin/write_node_callsigns_ulaw.sh
 
rm /var/lib/asterisk/sounds/rpt/nodenames/481480.ulaw
rm /var/lib/asterisk/sounds/rpt/nodenames/481481.ulaw
rm /var/lib/asterisk/sounds/rpt/nodenames/1399.ulaw
rm /var/lib/asterisk/sounds/rpt/nodenames/1398.ulaw
rm /var/lib/asterisk/sounds/rpt/nodenames/48148.ulaw
rm /var/lib/asterisk/sounds/rpt/nodenames/481482.ulaw

I forget where I found it, so here's the write_node script itself

write_node_callsigns_ulaw.sh

DM41 Save/Restore Statistics

anonymous@undisclosed.example.com (Anonymous) — Tue, 10 Feb 2026 18:01:25 +0000

←Hints & Tips

DM41 Save/Restore Statistics

Using Extended Memory to save Statistics Registers

Background

Statistics use 6 regular registers to keep track of data for calculating Mean and Standard Deviations.

Keeping a long-term record of a set of variables means not being able to use the Statistics functions for anything else unless steps are taken to save and restore the registers.

It is possible to save the 6 registers in a data file in Extended Memory and then use the statistics for other things, and restore the saved Statistics back to Main Memory when required.

By Default the Statistics registers start at R11 but this can be changed with the command ∑REG

This is the default list of Statistics Registers and contents

R11	∑x	Summation of x-values
R12	∑x²	Summation of squares of x-values.
R13	∑y	Summation of y-values.
R14	∑y²	Summation of squares of y-values.
R15	∑xy	Summation of products of x- and y-values.
R16	n	Number of data points accumulated.

Advantage Pac : CFIT application seems to reset ∑REG to 12

Extended Memory Data File

The statistics registers use 6 Main Memory registers, usually R11 → R16

We need to create a Data File in Extended Memory to hold these.

Put the name in ALPHA e.g. REGS
Put 6 in x register
excecute CRFLD to create the Data File REGS in Extended Memory

Once it's created it can be used to hold the contents of the 6 Statistics Registers

Save Registers to Extended Memory

We need to make sure our Data File is the current file and that the pointer is at the beginning of the file
- Put REGS in ALPHA
- Put 0 in X so that we put the pointer at the first register record in the data file.
- Execute SEEKPTA
Now we need to copy the 6 Registers R11 → R16 to the Data File REGS
- ensure REGS is still in ALPHA
- put a number in X to indicate which range of Registers to save, this is bbb.eee where b is the beginning register and e is the end
  - put 11.016 in X
- execute SAVERX

Restore Registers from Extended Memory to Main Memory

We need to make sure our Data File is the current file and that the pointer is at the beginning of the file
- Put REGS in ALPHA
- Put 0 in X
- Execute SEEKPTA
We can copy the 6 registers held in the Data File REGS back to R11 → R16
- ensure REGS is still in ALPHA
- put a number in X to indicate where the recovered registers will be put in Main Memory
  - put 11.016 in X
- execute GETRX

A program to make it easier

It is possible to change the base register of the 6 Statistics Registers, away from the default of R11.

We need to take this into account.

This uses the query ∑REG? to find the base register, then create bbb.eee using simple arithmetic.

When used in SAVER (saveRegs) we ensure we copy the current Statistics Registers data.

When used in GETR (getRegs) we ensure we restore our data to the Registers currently set to be the active Statistics Registers (they may have changed since first saving them)

Multiple Saved Files

It's possible to have more than one Extended Memory file with Stats registers.

This could keep track of different sets of statistics and allow restore, update, save for many sets of statistical data.

I've set up two data files : REGS and CHESS in extended memory and made two version of the simple program above, the only change is to alter the lines which put the name of the file in ALPHA

Then I thought of adding a 7th Register holding the DATE of the latest SAVE for the CHESS statistics, so I can keep track of whether I'm up to date in entering the scores.

Delete the original CHESS Data File & make a new one with 7 registers

ALPHA → CHESS
execute PURFL
X = 7
ALPHA still → CHESS
execute CRFLD to create the new 7-register data file

The date is automatically stored in the register just after the Stats - in general in R18 when ΣREG is 12 - and automatically adapts the register used depending on ΣREG?

DM41X HP16C Module

DM41X HP16C Module

Keyboard Overlay

Background

The HP16C Programmer's Calculator is made for manipulating numbers in Binary/Octal/Hexadecimal/Decimal to help with programming and other areas that rely on the nitty-gritty of bit-twiddling.

Swiss Micros make a modern hardware emulation (similar in form to the DM15L I already own) but rather than adding another calculator to my (growing) collection I found there is a ROM/Module method to add all (and more) the same features to the DM41X (and presumably the HP41, if you can find a hardware ROM plugin with it).

I occasionally need to do some conversions/calculations into Hex and Binary (thinking of TCP/IP networking, subnet masks etc. or perhaps debugging RS232 serial data, or when writing rig control software?) and being able to do everything on the DM41X (along with the Complex Number module) means the DM41X will become even more useful day-to-day.

The HP16C

The HP16C Manual : https://literature.hpcalc.org/community/hp16c-oh-en.pdf

The DM16L

https://www.swissmicros.com/product/dm16l

I bought a DM16L in August 2022

Basic Operation

Like the 41Z Complex Number module, a USER keyboard assignment is made to a trigger command which then automagically re-maps the whole keyboard for one command, then it reverts to normal. A mental image of the re-mapped keyboard starts to develop with use, making operation easier with time.

I've assigned the LN key to the trigger command 16C for the USER keyboard

SHIFT ASN ALPHA SHIFT 1 SHIFT 6 C ALPHA LN

User Keyboard comments

With USER keyboard active I generally won't miss the loss of LN as I rarely use it.

If I do need LN I can simply turn off the USER keyboard.

The same applies for using the ∑+ key for entering Statistical Data - it's assigned to the Complex Keyboard trigger ΣZL.

I won't ever be using statistics at the same time as complex numbers (or HP16C functions).

The USER keyboard can generally remain active all the time except when I want to do statistics or calculate a natural logarithm. Two easy sacrificed keys. Are there others I can do without for additional assignments to frequently used functions or modules?

I've noticed that it's possible to assign the 16C command to the ∑+ key.

This allows a single key to be used both to trigger 16C mode, and then to trigger input mode 16NPT.

It means less hopping around.

The ∑+ key is doing double duty but ∑+ ∑+ seems a little more user friendly than LN∑+ for inputting numbers.

SHIFT ASN ALPHA SHIFT 1 SHIFT 6 C ALPHA ∑+

16KEYS?

16KEYS? info

I played with the LADYBUG module recently ( see DM41X Ladybug Module ) and enjoyed the more “immediate” keyboard input - with the whole keyboard re-mapped while using the module (in “INTEGER” mode). No need to preface each instruction with a trigger to enable the special keyboard for one command at a time.

I found that the HP16C Module can be switched to “full-time” 16KEYS mode too….

You need to get to the ∑BITS launcher and then select Y (for 16KEYS) and answer Y or N.

The 16KEYS function can't be reached any other way, that I've found. The simplest way is to use the DM41X CST menu to run the 16C ∑MOD launcher, then press SHIFT to switch to the ∑BITS launcher, then select Y (for 16KEYS).

You'll need to enable USER key mode, and then the 16C module can be used without the the need to trigger every command with 16C (normally ASN'd to LN key).

You still need to use 16NPT to input numbers (this is mapped to the A (∑+) key. Otherwise most things are just more intuitive. No need to use 16C before an arithmetic operation like + or - etc.

Example

Switch to BIN view

B

Enter a binary number 10111011

16NPT10111011ENTER

Convert to HEX

E

H: bb

Convert to DEC

D

d: 187

Enter a Decimal Number 23

16NPT23ENTER

d : 23

Add them

+

d: 210

Convert to BIN

B

b: 11010010

Much more intuitive….

Select the Base

USER keyboard active.

16C is USER assigned to LN - referred to as 16C hereafter.

I'll use the alpha letter for the top-row keys to describe them for Base Selection

16C B = BINARY

16C C = OCTAL

16C D = DECIMAL

16C E = HEX

Enter a number

HEX

Enter HEX value 5F

Use the 16NPT function which lives on the Σ+ button (it switches from the complex assigned ΣZL to 16NPT when the 16C is invoked)

16C E (to get into HEX mode)

16C 16NPT 5 F ENTER

Convert to BIN

16C B gives 1011111

Enter a new BIN number

16C 16NPT (i.e. Σ+) 1101100 ENTER

Add them together

16C + gives 11001011

Convert to HEX

16C E gives Cb

Convert to DEC

16C D gives 203

always enter numbers with 16C 16NPT the number ENTER

always use the 16 versions of mathematical functions

16C +

16C X

etc.

NOT, OR, AND, XOR

These are on shifted (and triggered with 16C) math keys:

- = NOT

+ = OR

x = AND

÷ = XOR

Example, in binary….

AND two numbers:

11011101 AND 10001001 →

16C B (to get into Binary mode if needed)

16C 16NPT 11011101 ENTER

16C 16NPT 10001001 ENTER

16C SHIFT X gives 10001001

In HEX…. XOR →

16C E (to get into HEX)

16C 16NPT BEEF ENTER (first number) (make sure at least 16-bit word size for this example Word Size

16C 16NPT CAFE ENTER (second number)

16C SHIFT ÷ (XOR) gives 7411

Convert answer to DEC

16C D gives 29713

Convert answer to BIN

16C B gives a long string of 1 and 0 that scroll across the screen…

Window

View the long BIN number using a WINDOW to look at 8 bits at a time…

16C SHIFT R/S

This asks WINDOW _ and enter 0 for the 1^st (MSB) 8 bits:

W0: 11101000:b

Scroll to sequential WINDOW slices with + and - →

+ →

W1: 0010001:b

+ →

W2: :b

The full 16-bit number is therefore:

111010000010001

Setting Word Size and negative number convention

The word size can be up to 64 bits. In general most stuff is 4, 8 or 16 bits wide, so you can set the size of the binary number in the ∑MOD launcher:

16C USR (one of several different ways of getting to ∑MOD)

16KEYS methods

There is then a choice of settings

B:O:D:H:F - 0: 1:2:W:S:?

The first four can set the mode to Binary, Octal, Decimal, Float.

0 sets UNSIGNED integers
1 sets ONE'S COMPLEMENT
2 sets TWO'S COMPLEMENT

Word size is checked with S

Word size is set with W then enter (eg) 16 to set 16-bit words.

Word Size can also be set directly from a 16C keyboard function 16WSZ accessed via 16C SHIFT 5 rather than via the ∑MOD menu/launcher

? displays the current settings (press ? then quickly press and hold it to read the displayed info)

0c - 16 - DEC

This means unsigned integers, 16-bit words, DECIMAL mode.

Other Launchers

Lots of functions are available in launcher sub-menus, eg a menu of rotate functions, or shift functions.

The various launchers are available cyclically via the 16C XEQ along with SHIFT and A

Some trial and error is needed to find what you want, but it starts:

16C XEQ → R: L LN RN R which is a menu to do bit-rotations.

Rotate 1-bit Left by pressing top-row button B

Rotate N-bits left with top-row button C (and enter the number of bits)

Rotate N-bits Right with top-row button D (and enter the number of bits)

Rotate 1-bit Right with top-row button E.

From the R menu:

A give the S: L LN RN R menu to SHIFT bits Left or Right

From the S menu:

XEQ gives ∑R : …………………. which gives lots of options to do things rightwards with the bits. list them

This goes on via XEQ and SHIFT (ORANGE button) to access several menu launchers. Trial and Error and muscle memory.

A brief map/list of launchers

16CXEQ → ∑ROT

∑ROT → XEQ → ∑LEFT → XEQ → ∑MOD → XEQ → ∑ROT

∑ROT → A → ∑SHF

∑SHF → XEQ → ∑RIGHT → XEQ → ∑BIT → XEQ → ∑SHF

∑LEFT ↔ SHIFT ↔ ∑RIGHT

∑MOD ↔ SHIFT ↔ ∑BIT

∑SHF ↔ SHIFT ↔ S“:

∑ROT ↔ SHIFT ↔ RC:

Registers etc

Numbers can be saved in 16C registers via 16C STO NN

e.g. save a subnet mask of 11111100 into 16C REG 00 (i.e. the last octet of a /30 network 255.255.255.252)

16C B (go to BINARY mode)

16C 16NPT 11111100 ENTER 16C STO 00

Use the stored value

What is 123 AND MASK ? (what's the network base number for host address of 123 using a netmask of 252?)

16C D (decimal so you can enter 123 rather than a BINARY number)

16C 16NPT 123 ENTER

recall mask (it doesn't matter that it was initially stored as a BINARY number, it's displayed in whatever base you are currently using)

16C RCL 00

AND them

16C SHIFT x

answer is 120

The MASK is still in 16-Register 00 if needed again….

Net address of a host with address 43?

16C D

16C 16NPT 43 ENTER

16C RCL 00

16C SHIFT x

answer : 40

xxx.xxx.xxx.43 has a network address of xxx.xxx.xxx.40

Most Used Functions

16C = LN (i.e. E on top-row)

16NPT = ∑+ (i.e. A on top-row, must be triggered with 16C) ²⁾

16C 16NPT type in a number ENTER (enter a number in whatever base is currently selected)

BIN OCT DEC HEX = 16C then one of top-row buttons B, C, D, E (select the required base)

∑MOD = 16C USR …. or 16C SHIFT 2 (open a settings menu to set the choice of mode/word/signed)

NOT / OR / AND / XOR = 16C SHIFT then one of - + x ÷ (logic functions)

RL / RR = 16C then one of SIN or COS (rotate Left or Right 1-bit)

RLN / RRN = 16C SHIFT then one of SIN or COS (rotate Left or Right N-bits _ _)

SLN = 16C TAN (shift Left N-bits _ _)

SRN = 16C SHIFT TAN (shift Right N-bits _ _)

Sb = 16C SHIFT 7 (set a bit _ _)

Cb = 16C SHIFT 8 (clear a bit _ _)

B? = 16C SHIFT 9 (is a bit _ _ set or not?)

#BITS = 16C SHIFT ∑+ (i.e. A on top-row) (how many bits are high?)

See Keyboard Overlay Pic above for more hints on 16C key assignments

EVERYTHING STARTS WITH ''16C''

It is recommended to change the assigned key occasionally to prevent wearing it out…..

VPS Notes

GM4SLV.ORG.UK VPS : New VPS created 6^th March 2025

To separate my personal wiki site from yaddnet.org server
Wiki backed-up and moved from yaddnet.org to new gm4slv.org.uk VPS
SSL Certificate replaced to enable HTTPS

New VPS : March 2025

New VPS 1 obtained at Fasthosts

Type:Virtual Machine
Size:vps 1 2 60
Cpu:1 vCore
RAM:2 GB
Disk:60 GB NVMe SSD

Distributor ID: Ubuntu
Description:    Ubuntu 24.04.1 LTS
Release:        24.04
Codename:       noble

Installed PHP and Apache2

gm4slv@gm4slv:~ $ php --version
PHP 8.3.6 (cli) (built: Dec  2 2024 12:36:18) (NTS)
Copyright (c) The PHP Group
Zend Engine v4.3.6, Copyright (c) Zend Technologies
    with Zend OPcache v8.3.6, Copyright (c), by Zend Technologies

configured SSL per previous method SSL Install on VPS
changed SSH port from default 22 to a new port, changed VPS firewall to suit new SSH port
Ubunto OS brought up to date: sudo apt-get update and sudo apt-get upgrade and sudo apt-get dist-upgrade

Dokuwiki Security

previous installations used .htaccess to prevent web access to data/conf/lib/bin etc. directories
this time I decided not to use .htaccess but to follow the alternative instructions in https://www.dokuwiki.org/security to use LocationMatch

LocationMatch method

Apache is told which directories (data, conf, bin, inc, vendor) to make private. The downside is that this configuration might need altering if new directories are added during dokuwiki upgrades.

add to /etc/apache2/apache2.conf

<LocationMatch "/(data|conf|bin|inc|vendor)/">
    Order allow,deny
    Deny from all
    Satisfy All
</LocationMatch>

sudo service apache2 restart

.htaccess method

the secured directories in dokuwiki have suitable .htaccess files already. Apache needs to betold to allow them to alter behaviour

AllowOverride All

add to /etc/apache2/apache2.conf

         <Directory /var/www/html>
                Options Indexes FollowSymLinks MultiViews
                AllowOverride All
                Order allow,deny
                allow from all
        </Directory>

sudo service apache2 restart

SSH Security

Configured sshd to disallow password-logins and only accept public-key authentication
- be careful to check the files in /etc/ssh/sshd_conf.d for hidden config options!
uploaded public keys from
- Puttygen for putty on laptop
- ConnectBot app on phone
saved both in ~/.ssh/authorized_keys
now only logins with a valid public key will succeed.
- In the event of a loss of the public keys it's still possible to gain access via Fasthosts account dashboard
  - → then reconfigure sshd to accept password logins again until new keys can be uploaded.

06/04/25 : Renew SSL certificate

Same procedure as before
- Download “Certificate” → signed.crt
- Download “Intermediate Certificate” → ca.pem
- Upload via WinSCP to VPS
- Copy old /usr/local/ssl/signed.crt → signed.crt.old
- Copy old /usr/local/ssl/ca.pem → ca.pem.old
- Copy new files into /usr/local/ssl
- Restart Apache
There were 2 “Intermediate Certificate” for download from Fast Hosts…
- I used the one named 7D5B5126B476BA11DB74160BBC530DA7.cer
- This is the same as the one used when I renewed YaddNet.org SSL yaddnet_ssl_renewal
- It seems that the intermediate certificate is not unique to the domain being secured, it's a certificate that verifies the identity of the authenticator of the domain's SSL certificate.

UPDATE ON TWO INTERMEDIATE CERTIFICATES 05/07/25

I've discovered that the 2 Intermediate Certificates are necessary to complete the chain of authority.

What should be done is to join them together into one ca.pem file (and in the correct order…. )

[root@wiki:/home/g4slv/ssl]# cat 397A66CC2756362E0DAA87CA6EABE3B1.cer 00D27FBBC1DE359E5216AD6149586099C4.cer > ca.pem
 
[root@wiki:/home/g4slv/ssl]# cp ca.pem /usr/local/ssl
 
[root@wiki:/home/g4slv/ssl]# systemctl restart apache2

Check correct SSL operation at https://www.ssllabs.com/ssltest/analyze.html

Installing SSL for HTTPS

Create Certificates

First : obtain SSL Certificates

Configure APACHE

Second : configure Apache to use HTTPS

copy self generated gm4slv.org.uk.key from the “openssl” command to /usr/local/ssl/
copy the *crt for the newly obtained signed *.crt file renamed as signed.crt to /usr/local/ssl
copy the “intermediate” file to /usr/local/ssl/ (renamed as ca.pem)
edit apache config… looks like /etc/apache2/sites-available/default-ssl.conf
- SSLCertificateFile /usr/local/ssl/signed.crt
- SSLCertificateKeyFile /usr/local/ssl/gm4slv.org.uk.key
- SSLCertificateChainFile /usr/local/ssl/ca.pem
make symlink sites-enabled/default-ssl.conf pointing to sites-available/default-ssl.conf
a2enmod ssl
restart apache2
will it be listening on port 443? yes
open firewall port 443 on Fasthost control panel
Can I reach it with https://gm4slv.org.uk? yes
Can I still reach it with http://gm4slv.org.uk? yes
force redirect of plain HTTP: to HTTPS:
add to 000-default.conf:

        ServerName gm4slv.org.uk
        ServerAlias www.gm4slv.org.uk
        Redirect permanent / https://gm4slv.org.uk/

taken from https://linuxize.com/post/redirect-http-to-https-in-apache/
restart apache2
verify SSL access ok - yes
verify non-SSL is redirected to SSL - yes

Confirm proper security

Browse to https://gm4slv.org.uk

20/04/23 Renew SSL Certificate

new Signed and CA (intermediate) certificates obtained and installed in /usr/local/ssl

Hardware Upgrade 20/4/23

Original configuration VPS XS : 500MB RAM and 10GB SSD @ £1 per month (plus VAT)
Upgrade to VPS S : 1GB RAM and 20GB SSD @ £3 per month (plus VAT)
VPS rebooted for upgrade
RAM seems to have increased to 1GB but reported 'df -h' still shows 7.5GB total for / and 1.9GB for Swap. This is only 10GB.
Perhaps more time is needed for VM to catch up and expand the Virtual Hard Drive?
Gotcha…. the Virtual Drive was increased to 20GB, but not the partition or the filesystem… the only way to get a full 20GB was to “rebuild” the VPS….
took a backup of the dokuwiki files (rsync mirrored them to shack PC). Hit “Rebuild” and built a new VPS. Applied for replacement SSL keys (had to make a new CSR/KEY first)…
Used rsync to send back the dokuwiki files (from the shack PC mirror)
set up Apache2 to use the new SSL certificates…
VPS is now rebuilt and all wiki files restored & Apache2 uses HTTPS.

Debian Upgrade 15/2/24

Upgraded from Buster (10) → Bullseye (11)
Upgraded Dokuwiki (this needed PHP7.4 from Buster, which is why the Debian upgrade was necessary) to the newest version (Release 2024-02-06a “Kaos”)
Upgraded from Bullseye (11) → Bookwork (12) - might as well get to STABLE

Over the air ID

←AllStar Linking

Over the air ID

What's the requirement in the UK now, for identification of Gateways which are operating under your own licence, rather than an Notice of Variation that used to be needed in the olden days?

Licence Quote

Identification
  21. The licensee that shall ensure that:
    a) the station is clearly identifiable at all times;
    b) the call sign is transmitted as "frequently as is practicable during transmissions"; and
    c) the Call sign is given in voice or other appropriate format consistent with the mode of operation.

and nothing at all in the “Gateways” section that would require anything more than as frequently as is practicable.

Gateway Operation

Gateway operation
  14. The Radio Equipment may be used as a Gateway and may be operated (but not
      controlled) by other radio amateurs without supervision, providing that the Licensee:
      a) ensures that the Gateway transmits at powers no greater than 5 Watts ERP;
      b) is able to demonstrate that reasonable steps have been taken to minimise the risk 
         of the Gateway causing undue interference to other authorised uses of radio and
         provide evidence of this if requested by Ofcom;
      c) is able to close down the Gateway within two hours of being required to do so by
         Ofcom.
      d) takes all reasonable steps to ensure that the Gateway is only used by an Amateur;
      e) remains responsible for the operation of the Gateway and compliance with the
         terms, conditions and limitations of the Licence; and
      f) Anyone wishing to establish a link to a Repeater must have the written permission
         of the Repeater keeper to do so.

Voice IDs

I've added a couple of Crontab commands
- The first one plays the ID every hour (that seems to meet “as frequently as is practicable”)
- The second plays the time, after the ID on the hour

00 * * * * sudo /usr/sbin/asterisk -rx "rpt localplay 481480 /var/lib/asterisk/sounds/custom/gm4slv" > /dev/null 2>&1
00 * * * * sleep 4 && sudo /usr/sbin/asterisk -rx "rpt fun 481480 *81" >/dev/null 2>&1

The sound file “gm4slv.ulaw” came from the Node Callsigns instead of Numbers script, renamed from 481410.ulaw to gm4slv.ulaw and stored in /var/lib/astersisk/sounds/custom
The second crontab entry plays Good [morning|afternoon|evening] the time is…..
They play sequentially at the top of the hour

This works, but it turns out to be an annoyance - especially when leaving a VHF H/T monitoring the gateway within earshot of people who don't appreciate such interesting radio signals

I disabled it after a couple of hours…..

Morse IDs

The standard morse ID still goes out after a transmission - if no ID has been sent for at least 15 minutes (because the Gateway hasn't been used for more than 15 minutes).
I've changed the morse tone frequency and amplitude

[morse]
speed = 20                              ; Approximate speed in WPM
frequency = 600                         ; Morse Telemetry Frequency
amplitude = 2048                        ; Morse Telemetry Amplitude
idfrequency = 600                       ; Morse ID Frequency (was 1065)
idamplitude = 512                       ; Morse ID Amplitude (was 1024)

DESK15 - Calculator suite (including a Spreadsheet) for the DM-15

____________________

PREAMBLE
____________________

The HP-15c was probably the most simple but versatile scientific calculator.
Similar to DESK42 (for the DM42) DESK15 offers an alternative firmware for the
DM15/DM15L replica of Swissmicros with a suite of some applications like a
complex number calculator, a spreadsheet, a symbolic, a tabletop calculator
and even a sliderule and a simple text editor.

Have fun!
deetee


____________________

INSTALLATION
____________________

To install a new firmware to a DM-15 (Voyager) calculator have a look at
chapter Firmware Update of the Swissmicros Voyager Series User Manual at:
  https://technical.swissmicros.com/voyager/firmware/

On linux computers for example install the package lpc21isp and flash the
desired firmware (hex file) to the calculator with:
  sudo lpc21isp <firmware.hex> /dev/ttyUSB0 115200 12000

After starting this command press the reset button on the backside of the
calculator with a paperclip. After the flashing procedure ends you might need to
reset the calculator again. Every Swissmicros-Calculator has a reset button
on the PCB (even if there is no hole to reach it).


____________________

DESK
____________________

When you start DESK15 the first time you see the application launcher DESK. You
can launch the desired application with the keys 7, 8, 9 and 4, 5, 6:

  7 PLEX ... Complex Number Calculator
  8 FLEX ... Symbolic Calculator
  9 RAX  ... Spreadsheet
  4 TTOP ... Table Top Calculator
  5 RULE ... Slide Rule Simulation
  6 TEX  ... Text Editor

On the right side of the screen you see some extra information like the battery
level, date (day) and time (24 hour format).

Please note that the battery level is a momentarily value that varies due to the
momentarily activity of the calculator. But if you see the empty battery symbol
quite often you might consider changing the battery.

____________________

PLEX
____________________

PLEX is a scientific calculator generically designed to work with complex
numbers. Many routines of PLEX are used by other applications (even if they work
with real numbers only). Beside advanced mathematic functions it even offers an
extensive function analysis (function value, slope, solve, integrate and plot).

PLEX supports the following functions:
  Basic
    0-9.      Number input
    ENTER     Enter number (stack lift) or duplicate TOS

DM41X Matrix

anonymous@undisclosed.example.com (Anonymous) — Sun, 08 Feb 2026 08:26:58 +0000

←Hints & Tips

DM41X Matrix

Matrix functions in the Advantage Pac

Background

The matrix functionality isn't a standalone program, with a menu, like CFIT and PLY.

It's a collection of individual programs that can be used for many matrix tasks. Each one has to be called individually as needed.

There are many commands, the most used are those for

Dimensioning a new matrix MATDIM
Editing a matrix to enter values - there are 2 versions
- Real Matrix MEDIT
- Complex Matrix CMEDIT
Inverting a matrix MINV
Transposing a matrix TRNPS
Finding the determinant MDET
Multiplying two matrices together M*M
Solving a system of equations defined by 2 matrices MSYS

Shortcuts to Matrix Commands

To make things easier it's best to use the DM41X CST custom command shortcut mechanism.

Start with a blank CST and add the commands you need. Then save this CST so that it's easy to switch to other CST setups, and then return to the Matrix setup later.

I have the following

A	`MATDIM`	I
B	`MEDIT`	J
C	`CMEDIT`	K
D	`MINV`	L
E	`M*M`	M	`ZK?YN`
F	`MDET`	N	`EMDIR`
G	`TRNPS`	O	`EMDIRX`
H	`MSYS`	P	`PURFL`

Matrices are saved in Extended Memory, and I put commands in CST to find and remove them once I'm finished: EMDIR, EMDIRX and PURFL and I have ZK?YN to quickly access DM41X 41z Module complex number functions (assuming the module is plugged-in).

Basic Workflow

All matrix addressing is done via the ALPHA register

Dimension a new Matrix

Put the name of the matrix in the ALPHA register.
- Use single letters A, B, C etc. - these will create the matrix in Extended Memory
- ALPHA A ALPHA
Put the dimensions in the X register
- this is in the form r.ccc with 3 decimal places for the column
- for a 3×3 : 3.003 (3 rows, 3 columns)
- for a 4×2 : 4.002 (4 rows, 2 columns)
- 3.003
  - puts the dimensions in the X register ready for MATDIM to assign to the matrix named in ALPHA
Execute the MATDIM command from the CST menu A
- CST A
- This creates matrix A in extended memory

Populate a new Matrix

Populate the matrix with values using MEDIT from the CST menu B

For a 3×3 matrix

| 1 1 -1 | | 4 6 6 | | 1 8 9 |

CST B
1:1= 1R/S
1:2= 1R/S
1:3= 1CHSR/S
2:1= 4R/S
2:2= 6R/S
2:3= 6R/S
3:1= 1R/S
3:2= 8R/S
3:3= 9R/S

Determinant

With A still in the ALPHA register use the MDET command from the CST menu F

CST F
-50.000

Matrix A will now be in LU Decomposition form.
It can be used in this form for some other functions, but it's possible to get it back to normal form by Inverting twice using MINV from CST menu D
- CST D
- CST D
- You can check the element values by using MEDIT again, but just cycling through each with R/S and not changing any values
  - it's possible to set flag 08 which prevents any changes to values

Multiplication

Using M*M

For matrix multiplication you need 3 matrix definitions:

Matrix A and Matrix B are the two matrices to be multiplied
- Matrix A and Matrix B are dimensioned with MATDIM and populated with MEDIT
Matrix C is the matrix to hold the result
- Matrix C is simply dimensioned with MATDIM and will be filled automatically by the function M*M

To multiply two matrices together they must have the correct dimensions

Columns in A must equal Rows in B
Results matrix C will have the dimensions Rows of A x Columns of B

Create Matrix A

Follow the same procedure as above.

Make sure ALPHA has only the letter A

A different numerical example

A will be a 3×2 matrix

use MATDIM via CST menu
- 3.002 CSTA

| 2 3 | | 4 5 | | 7 6 |

Use MEDIT via CST menu
- CST B
- 1:1= 2R/S
- 1:2= 3R/S
- 2:1= 4R/S
- 2:2= 5R/S
- 3:1= 7R/S
- 3:2= 6R/S

Create Matrix B

B will be a 2×2 matrix

Make sure ALPHA only has B and then dimension B with MATDIM from CST menu A

ALPHA B ALPHA
2.002 CSTA

| 2 3 | | 4 5 |

* Use MEDIT via CST menu

CST B
1:1= 2R/S
1:2= 3R/S
2:1= 4R/S
2:2= 5R/S

We now have defined the matrices to be multiplied together.

Create Matrix C

We need a results matrix C

The dimensions of C will be rows of A and columns of B which is 3 rows and 2 columns : 3.002

Make sure ALPHA only has C and dimension C with MATDIM from CST menu A

ALPHA C ALPHA
3.002 CSTA

That's enough to create the results matrix

Multiply the matrices

Put the matrix names in ALPHA in the form Matrix 1,Matrix2,Results Matrix
- ALPHA = A,B,C
ALPHA A , B , CALPHA
Execute M*M from the CST menu
- CST E
C will now hold the answer

View the result

Put C in the ALPHA register
ALPHA C ALPHA
Use MEDIT from the CST menu and cycle through the elements (it's a 3×2 matrix)
CST B
- 1:1= 16.000? R/S
- 1:2= 21.000? R/S
- 2:1= 28.000? R/S
- 2:2= 37.000? R/S
- 3:1= 38.000? R/S
- 3:2= 51.000? R/S

The result in C is

| 16 21 | | 28 37 | | 38 51 |

System of Equations

A simple example first

Set of Equations

3 unknowns

3x + 4y + 6z = 39.7 2x - 4y - 3z = -7.0 y + 8z = 63.4

Matrix representation

Matrix A

| 3 4 6 | | 2 -4 -3 | | 0 1 8 |

Dimensions 3.003

Matrix B

| 39.7 | | -7.0 | | 63.4 |

Dimensions 3.001

Simultaneous Equations represented in Matrix Form

|A| x |C| = |B| | 3 4 6 | | x | | 39.7 | | 2 -4 -3 | x | y | = | -7.0 | | 0 1 8 | | z | | 63.4 |

Create Matrix A

ALPHA A ALPHA
3.003 CST A (MATDIM)
CST B (MEDIT)
- 1:1= 3 R/S
- 1:2= 4 R/S
- 1:3= 6 R/S
- 2:1= 2 R/S
- 2:2= 4 CHS R/S
- 2:3= 3 CHS R/S
- 3:1= 0R/S
- 3:2= 1R/S
- 3:3= 8R/S

Create Matrix B

ALPHA B ALPHA
3.001 CST A (MATDIM)
CST B (MEDIT)
- 1:1= 39.7 R/S
- 2:1= 7 CHS R/S
- 3:1= 63.4 R/S

Run MSYS

Put A,B in ALPHA
- ALPHA A , B ALPHA
Run MSYS - the solution matrix for x, y and z will be placed in Matrix B
- CST H

Examine Matrix B

Put B in ALPHA
- ALPHA B ALPHA
Run MEDIT from CST menu
- CST B (MEDIT)
  - 1:1= 1.500 'R/S/
  - 2:1= -3.800 R/S
  - 3:1= 8.400 'R/S

The solution

x = 1.5 y = -3.8 z = 8.4

Matrix A

A is now in LU-decomposed format
It can be restored to normal by Inverting Twice
Put A in ALPHA
Run MINV via CST menu twice
- CST D CST D
A is now back to normal and can be inspected and edited by MEDIT via the CST menu

Another way to solve a system

Instead of the MSYS function you could do it manually by entering Matrix A and Matrix B, and define Matrix C such that

A X C = B

C = B / A

C = A* X B where A* is Inverse A

Create Matrix C with dimensions 3.001 in the usual way then and do:

Put A in ALPHA
Invert A using MINV from CST menu (A is replaced by its inverse)
Put A,B,C in ALPHA
Multiply using M*M
- this multiplies B by the inverse of A which is effectively dividing B by the original A
C now contains the solutions for x, y and z
Put C in ALPHA
Examine C with MEDIT
- 1:1= 1.500 R/S
- 2:1= -3.800 R/S
- 3:1= 8.400 R/s
This preserves B unlike the MSYS method.
The Inverse of A can be reversed by repeating MINV with A in ALPHA
We can even run M*M on A and C to re-create B
- Put A,C,B in ALPHA
- Run M*M from CST menu
- B will be re-created

The Complex Matrix

It is possible to define, edit and carry out operations with matrices containing Complex Numbers.

The matrix is defined with twice as many rows and columns as appears necessary, and edited with the function CMEDIT, in CST menu C

Example Definition

| 1+j2 5+j6 | | 3+j4 7+j8 |

Two rows and two columns 2×2 containing complex numbers, so the definition/dimension is 4.004

The numbers are actually saved as if in a larger real matrix as

| 1 -2 5 -6 | | 2 1 6 5 | | 3 -4 7 -8 | | 4 3 8 7 |

The entry is via CMEDIT via CST menu C, which asks for each Real and Imaginary part in turn

ALPHA A ALPHA
4.004 CST A
CST C
- RE. 1:1= 1 R/S
- IM. 1:1= 2 R/S
- RE. 1:2= 5 R/S
- IM. 1:2= 6 R/S
- RE. 2:1= 3 R/S
- IM. 2:1= 4 R/S
- RE. 2:2= 7 R/S
- IM. 2:2= 8 R/S

Multiplication of Complex Matrices

Create a second matrix

Matrix B of size 2×1 which can be multiplied by A as A x B

| 3+j4 | | 2+j6 |

Dimension second matrix

This is dimensioned as double the basic size of 2×1 : 4.002 and then populated with CMEDIT

ALPHA B ALPHA
4.002 CST A
CST C
- RE. 1:1= 3 R/S
- IM. 1:1= 4 R/S
- RE. 2:1= 2 R/S
- IM. 2:1= 6 R/S

Create a result matrix

Matrix 'C' which will be also be a 2×1 complex with dimension :4.002

ALPHA C ALPHA
4.002 CST A

Multiply A X B = C

ALPHA A , B , C ALPHA
CST E

Inspect Result Matrix C

ALPHA C
CST C
- RE. 1:1= -31.000 R/S
- IM. 1:1= 52.000 R/S
- RE. 2:1= -41.000 R/S
- IM. 2:1= 82.000 R/S

The result matrix is therefore

| -31+j52 | | -41+j82 |

Which agrees with my long-hand calculation (thanks to DM41X 41z Module )

|(1+j2).(3+j4) + (5+j6).(2+j6)| |(3+J4).(3+J4) + (7+J8).(2+J6)|

| (-5+j10) + (-26+j42) | | (-7+j24) + (-34+j58) |

| -31+j52 | | -41+j82 |

Systems of Complex Equations....

Once you can enter and manipulate Complex Matrices you can also use MSYS to solve systems with complex matrices in the same way as usual - the only difference is entering the matrices as Complex.

Clearing Up Extended Memory

After creating and manipulating (and some finger trouble) there will be a bunch of files in Extended Memory.

Most will be simple matrix definitions with obvious names A, B, C etc. but occasionally you'll accidentally have run MATDIM with some nonsense in the ALPHA register and created a nonsensical filename in extended memory, which it's tricky to spell out correctly in ALPHA in order to run PURLF - this is where EMDIRX comes in.

To simplify clearing up I include EMDIR, EMDIRX and PURFL in the CST menu.

Assuming you have other files in Extended Memory, the quickest way is to find the number of files in EM with EMDIR.

Run EMDIR from CST menu
- CST N
Count the files to find the number of the first file you've created using MATDIM - i.e. the first one after your other EM files
Put this number in x
Run EMDIRX from CST menu
- CST O
- this puts the name of the specified-numbered file in ALPHA and means you don't have to type it in yourself
Run PURFL from CST menu to delete this filename
- CST P
Run EMDIRX again (with the same number in X)
- If X returns as non-zero we've found another junk-matrix file in EM and ALPHA will have its name
- Run PURFL again
Keep doing this until EMDIRX returns 0.00 in X which means there are no more files to delete
- all your original files are still safe, as they are numbered below the number we were searching for

Another diversion... I3 Tiling WM

Another diversion... I3 Tiling WM

— John Pumford-Green 09/10/22 13:58

After setting up Alpine and some other console-mode software I got the urge to try going back to another window manager I've played with in the past - I3 WM

I used it on my touchscreen Raspberry Pi that used to live in the LandRover as a control panel for the Icom IC-M710 HF radio - as it's good for simple mouse-less control.

I delved into the usual round of other tiling WMs:

I3
DWM
Herbstluftwm (HLWM)

After setting up some things on I3 to work the way I wanted I didn't see the need to re-invent the wheel by spending time learning/configuring DWM or HLWM so I've settled on I3

There are some snippets of info and configs on a page in the Wiki:

I3 Window Manager

I have it setup on my laptop which runs Antix Linux from a USB memory stick, without using the Hard Drive, and with Persistent Storage working well it's a great, fast and responsive, Linux-on-the-desktop user machine. I'm limited by how much software can be installed, as it all has to fit in 3GB of RAM once it boots. There's some USB storage available for data/documents etc. too.

I'm also setting I3 up on the old laptop I have in the shed as my main fixed machine - which is where I'm learning to write 6502 Assembly, and using I3 tiling WM is great for this - one large tile can have a VIM session to edit the source code, smaller tiles with terminal/shell can be used to assemble the code and to write/burn it to EEPROM, and to handle GIT commits/uploads to GITHUB.

Linux is just so versatile!

DokuWiki Tweaks

anonymous@undisclosed.example.com (Anonymous) — Sun, 19 Apr 2026 15:02:31 +0000

←Dokuwiki

DokuWiki Tweaks

Hide Revisions and Page Source for not-ADMIN in Users

Edit ../lib/tpl/monobook/conf/tabs.php to add the check of AUTH_ADMIN for the tabs for Page Source and Revisions

            if(!empty($INFO["exists"])){
                $_monobook_tabs["ca-edit"]["text"] = $lang["btn_edit"]; //language comes from DokuWiki core
            }else{
                $_monobook_tabs["ca-edit"]["text"] = $lang["btn_create"]; //language comes from DokuWiki core
            }
        }
    }elseif (actionOK("source") && (auth_quickaclcheck($ID) == AUTH_ADMIN)){ //check if action is disabled and also that AUTH_ADMIN is logged in
        $_monobook_tabs["ca-edit"]["text"]      = $lang["btn_source"]; //language comes from DokuWiki core
        $_monobook_tabs["ca-edit"]["accesskey"] = "E";
    }
 
 
    //old versions/revisions tab
    if (!empty($INFO["exists"]) &&
            actionOK("revisions")
        && (auth_quickaclcheck($ID) == AUTH_ADMIN)) // check AUTH_ADMIN is logged in to see old revisions
        { //check if action is disabled
        //ATTENTION: "ca-history" is used as css id selector!
        $_monobook_tabs["ca-history"]["text"]      = $lang["btn_revs"]; //language comes from DokuWiki core
        $_monobook_tabs["ca-history"]["href"]      = wl(cleanID(getId()), array("do" => "revisions"), false, "&");
        $_monobook_tabs["ca-history"]["accesskey"] = "O";
        if ($ACT === "revisions"){ //$ACT comes from DokuWiki core
            $_monobook_tabs["ca-history"]["class"] = "selected";
        }

Include / Blog "Read More..."

The default is for a “read more…” link to be placed at the extreme right of the page - which is not ideal when using Monobook template.

I found the css setting that controls the position of “read more…” in ../lib/plugins/include/style.css

div.dokuwiki p.include_readmore {
  text-align: right;
}

changing it to

div.dokuwiki p.include_readmore {
  text-align: left;
}

solved the problem and “read more…” is now on the left, directly at the point that the eyes get to when reading a post on the main blog index page.

To prevent this being overwritten on updates I found it works to put the same stanza in ../conf/userstyle.css which should keep it safe…

Vector / Monobook tweaks

I like the Vector and Monobook templates, very similar feel to Wikipedia

Logout errors with later versions of Dokuwiki

After upgrading Dokuwiki to Igor it became impossible to log out due to a warning

Security Token did not match. Possible CSRF attack.

I initially ignored it but then downgraded back to Hogfather as there seemed to be no fix - other than to use a different template.

I recently upgraded to the latest Dokuwiki (Jack Jackrum), and upgraded all plugins and templates where possible. However the problem with logout with Vector and Monobook re-appeared.

I found there was a fix described on the forum:

https://forum.dokuwiki.org/d/20248-security-token-did-not-match-possible-csrf-attack-cannot-log-out

and the cure is to edit the appropriate line in main.php for each template, as the author seems not to be maintaining these templates any more, at least not the official ones accessed via Dokuwiki's Template/Extension installer. The github repository shows that the fix has been applied to Vector, and a pull request submitted to fix Monobook, the fixes haven't appeared in the official versions.

The does work, though…

For Vector edit /var/www/html/dokuwiki/lib/tpl/vector/main.php to add , 'sectok' ⇒ getSecurityToken() in the array statement after “do” ⇒ “logout”

 echo  "      <li id=\"pt-logout\"><a href=\"".wl(cleanID(getId()), array("do" => "logout", 'sectok' => getSecurityToken()))."\" rel=\"nofollow\">".hsc($lang["btn_logout"])."</a></li>\n"; //language comes from DokuWiki core

and the same for Monobook

 echo  "          <li id=\"pt-logout\"><a href=\"".wl(cleanID(getId()), array("do" => "logout", 'sectok' => getSecurityToken()))."\" rel=\"nofollow\">".hsc($lang["btn_logout"])."</a></li>\n"; //language comes from DokuWiki core

Monospace font

I found the style applied to monospace text was a little underwhelming.

I found the place to change it:

/var/www/html/dokuwiki/lib/tpl/{vector|monobook}/user/screen.css

add the the following and adjust as needed:

div#content .dokuwiki code {
  font-size: 100%;
  padding-left: 5px;
  padding-right: 5px;
  background-color: #eee;
  color: #00f;
  direction: ltr;
  text-align: left;
}

Footer Buttons

Remove the default footer buttons by editing {vector|monobook}/user/buttons.php and adding

For Monobook, change to

$_monobook_btns = array();

//delete all (defaults)
$_vector_btns = array();

this suppresses the inclusion of footer buttons from vector/conf/buttons.php

Add just the Dokuwiki and Vector/Monobook Buttons

Edit {vector|monobook}/user/buttons.php

Swap monobook for vector as appropriate

<?php
 
//check if we are running within the DokuWiki environment
if (!defined("DOKU_INC")){
    die();
}
//delete all (defaults)
$_vector_btns = array();  
 
//note: The buttons will be rendered in the order they were defined. Means:
//      first button will be rendered first, last button will be rendered at
//      last.
//DokuWiki button
$_vector_btns["dw"]["img"]      = DOKU_TPL."static/img/button-dw.png";
$_vector_btns["dw"]["href"]     = "https://www.dokuwiki.org/";
$_vector_btns["dw"]["width"]    = 80;
$_vector_btns["dw"]["height"]   = 15;
$_vector_btns["dw"]["title"]    = "DokuWiki";
$_vector_btns["dw"]["nofollow"] = !(cleanID(getID()) === "start");
 
//"vector for DokuWiki" button
$_vector_btns["vecfdw"]["img"]      = DOKU_TPL."static/img/button-vector.png";
$_vector_btns["vecfdw"]["href"]     = "https://www.dokuwiki.org/template:vector";
$_vector_btns["vecfdw"]["width"]    = 80;
$_vector_btns["vecfdw"]["height"]   = 15;
$_vector_btns["vecfdw"]["title"]    = $lang["vector_mdtemplatefordw"];
$_vector_btns["vecfdw"]["nofollow"] = !(cleanID(getID()) === "start");

Symbol Chooser font size

The drop-down picker for choosing a symbol to insert in the text being edited is very small in Monobook as standard.

It's controlled by the pickerbutton class and is set at 80% in the standard monobook css.

It's adjusted thus (to 1.2em) and some extra margin added around the symbols:

button.pickerbutton {

padding: 0px;
margin: 2px 2px 2px 2px;
border: 0;
background-color: transparent;
font-size: 1.2em;
cursor: pointer;

}

Put this in user/screen.css with all the other tweaks.

Mobile Scaling

The layout on a phone isn't too good, and can't be zoomed/scaled.

I found this thread:

https://forum.dokuwiki.org/d/12469-vector-template-doesn-t-display-correctly-on-mobile-devices/6

and applied the comment-out of the line :

//echo "<meta name=\"viewport\" content=\"width=device-width,initial-scale=1\" />";

in main.php and mediamanager.php

the page now scales/zooms okay to make it useable on a phone.

Dokuwiki Timezone

I noticed the timestamps on file creation/modification were in UTC
I'd rather have “local time” so I don't have to think too hard
The answer is here → https://www.dokuwiki.org/tips:timezone
I used the first option, after successfully testing the second (editing php.ini)
I created conf/local.protected.php with

<?php
date_default_timezone_set("Europe/London");

I did sudo chown www-data:www-data local.protected.php too, just to be sure
All looks good - pages created/modified while in summer time show the time in BST and pages modified in winter time show the time in GMT

Add DW2PDF

To allow export of pages from Wiki → PDF format install plugin dw2pdf
to enable functionality it was necessary to install php-mbstring package on the VPS
1. ```
sudo apt-get install php-mbstring
```
```
sudo service apache2 restart
```

UPDATE

— John Pumford-Green 26/04/23 10:04

removed dw2pdf plugin, it is largely unused and adds pointless bloat.

Increase maximum file size upload for Media Manager

edit php.ini
1. ```
sudo vi /etc/php/XX/apache2/php.ini
```
2. change upload_max_filesize = 2M to upload_max_filesize = 20M
3. change post_max_size = 2M to post_max_size = 20M
4. ```
sudo service apache2 restart
```

Allow any file-type upload

From https://forum.dokuwiki.org/d/3318-allow-upload-of-any-filetype/5

Edit /var/www/html/www/dokuwiki/inc/media.php and comment out :

    // because a temp file was created already
    //if (!preg_match('/\.(' . $regex . ')$/i', $fn)) {
    //    return [$lang['uploadwrong'], -1];
    //}

Acronyms & Abbreviations

I find the underlining and “explanation” of some abbreviations/acronyms by dokuwiki, when rendering a page, to be annoying.

such as DNS and ACL

The process is described HERE

To disable this I simply copied the default conf/acronyms.conf to a local version conf/acronyms.local.conf and then edited the local version to remove all the explanations.

Dokuwiki Template monospace font

the colour of the mono font is the same as general text and doesn't stand out as well as in other templates.
edit /var/www/html/dokuwiki/lib/tpl/dokuwiki/css/basic.less with a hex code for a better colour
- but see below for a better place to do the configuraiton

code {
    color: #c72522;
    font-size: 1.1em;
    padding: 0.1em 0.3em;

To prevent upgrades overwriting these changes - add them to /var/www/html/dokuwiki/conf/userstyle.css
pre relates to the blocks of <code> ////// </code>
code relates to monospaced text

pre {
        border-radius: 10px;

Bootstrap3 ThemeByNamespace

To force specific bootstrap/bootswatch themes dependant on the namespace

enable ThemeByNamespace option
create a file in <dokuwiki>/conf called bootstrap3.themes.conf
chown www-data:www-data bootstrap3.themes.conf
add the required theme/namespace mapping:

# Namespace  Bootswatch Theme
start                   bootswatch/darkly
public                  bootswatch/darkly
public:calculator       bootswatch/slate
public:journal          bootswatch/journal
private                 bootswatch/flatly
playground              bootswatch/united
private:wire2waves      bootswatch/paper
blog                    bootswatch/yeti

it seems necessary to disable showThemeSwitcher and to select a default theme to be used outside of any listed in the conf file

Alternative

Using the loadskin plugin

it's possible to switch to the default dokuwiki template when on a mobile device and the vector template when on a computer.

The loadskin plugin seems to lead to problems switching between monobook and vector - the navigation sidebar seems to disappear on one or the other. Not sure where the problem is.

Note Plugin

Various Coloured notes:

Monobook Tweaks

PDF Export Tab

The dw2pdf plugin provides a button on many templates to trigger export to PDF but not on monobook. It's possible to add a tab to the top of the page, beside the edit etc. tabs, to do the the pdf export function.

add the following code to to monobook/user/tabs.php

//PDF plugin: export tab
if (file_exists(DOKU_PLUGIN."dw2pdf/action.php") &&
    !plugin_isdisabled("dw2pdf")){
    $_monobook_tabs["tab-export-pdf"]["text"] = "pdf export";
    $_monobook_tabs["tab-export-pdf"]["href"] = wl(getID(), array("do" => "export_pdf"), false, "&");
}

Vector Interwiki Icons

The icon shown on interwiki links almost always appears as a small “lock” rather than the correct icon

commenting out the .link-https section in /vector/static/3rd/vector/main-ltr.css stops this :

div#content a.external,
div#content a[href ^="gopher://"] {
        background: url(static/3rd/vector/external-link-ltr-icon.png) center right no-repeat;
        padding: 0 13px 0 0;
}
 
/*
div#content a[href ^="https://"],
.link-https {
        background: url(static/3rd/vector/lock-icon.png) center right no-repeat;
        padding: 0 13px 0 0;
}
*/
 
div#content a[href ^="mailto:"],

QSO Logging

anonymous@undisclosed.example.com (Anonymous) — Thu, 04 Jun 2026 18:15:51 +0000

←Radio Topics

QSO Logging

2023 Logging setup

Paper Logbook

I've always (when I remember) used a Paper Logbook for CW and SSB contacts. I'm on the third book after starting the 1st one in March 1983.

I usually don't (but sometimes do) log Digimode QSOs on paper, as fldigi has its own ADIF logbook. However I've moved/installed/upgraded/deleted various fldigi installations on so many different PCs that I've actually lost all the logs anyway. I've recently started logging all QSOs in the paper logbook. There's no chance of “accidentally deleting” a real, paper logbook, after all.

Update July 2023

I initially started to make notes of each day's activity and QSOs here, in the wiki
This became a chore, too many separate things to do during/after a QSO
I ditched the wiki-diary idea but want to have more of a record of QSOs, and other notes on condx etc. than a simple one line entry in the logbook
I started keeping a paper “journal” - basically a more carefully created scratch-pad - with entries being done during the QSO - my notes done at the time.
The left hand page of the spread is a scribble/rough notes area and the right hand page of the spread has notes of activity, CQs made, CQs replied to, QSOs, callsigns, propagation data (SFI, A, K etc), beacons heard, anything really.
I still add an entry to both paper logbook and Xlog, but they don't need too much additional detail, as it's all in the “journal”

Electronic Logs

I've tried various PC based log systems over the years. A few years ago I had a major project to add all the old data from my paper logs into an electronic log - I think I used “logger32” on a windows PC. I started from August 2003, the date I re-activated my dormant interest in amateur radio, and I built my Elecraft K1.

I count this as “day zero” of my current radio incarnation.

I could then export the ADIF file and could use it to “pre-populate” any new log system I fancied trying.

I now use xlog on my shack's old Linux laptop. It has all the QSO data from August 2003 to the present (except most Digimode QSOs) and I continue to use xlog in parallel with a good old fashioned paper logbook.

I have also discovered that fldigi will automatically add each logged QSO to Xlog, if they are running on the same machine, which means I can now ensure my digimode QSOs are recorded alongside my CW and SSB QSOs.

As of August 26th 2023 I no longer keep an electronic log.

I have ceased LOTW uploads. QSLs are now direct only if anyone wants/needs confirmation of a QSO

LOTW

While I was adding all my historical QSO data to an electronic log I decided to “join” the ARRL Logbook Of The World and add my QSO data. I did it in various stages, but I think I've now got all my QSO records uploaded to LOTW. This is mainly to assist others in their paper chasing goals, as I'm not generally interested in getting QSLs in order to claim awards (I've only got 84 DXCC “confirmed” on LOTW for “Mixed”, with 65 in Phone and 65 in CW). If my uploads allow other people to reach targets, without me needing to write and post physical QSL cards, then it's easy enough to oblige with LOTW. I had to download the sourcecode and compile the latest version of TQSL from the ARRL website to run on Linux. I forget how I got the necessary certificates from ARRL….

Club Log

~~I created a ClubLog account and I also upload my ADIF exports at regular intervals. I embed the “last 30” QSOs on my qrz.com page.~~

Update July 2023

I decided it's too cumbersome, and with no obvious benefit, to upload ADIF files to ClubLog as well as to LOTW
- ClubLog has no purpose, really, for me at the moment

Update August 28 2023

I have decided to drop ALL computer logging
- this means no LOTW either
I want a simpler radio shack, without reliance on computer for logging or any other purpose.
Logging : paper log book
Notes : on paper in separate “diary” made during QSO - these can be dated and kept as a reference
- Notes on radio setup, antennas, beacons etc., solar conditions etc. are in the same “diary” - as a record of day to day activity alongside any QSOs etc.
No RBN checking, no QRZ.COM checking.
Re-start card-index of stations worked, if not too time-consuming?

Workflow

~~start flrig & ensure correct communication with IC-7200~~
~~start fldigi & ensure it controls the IC-7200 via flrig~~
~~start xlog & ensure it shows the correct radio frequency (when the freq. log button is pressed)~~
have QSOs in ~~fldigi or~~ CW and log in paper logbook ~~as appropriate~~
~~export log ADIF file from xlog - selecting the latest QSO numbers, rather than the whole log~~
~~use TQSL to sign and upload this latest ADIF export to my LOTW account<?del> * <del>use the ClubLog website to upload this latest ADIF export to my CLubLog account~~

A typical project

monitor_dev.s setup

Put the asm source for the project in a folder (/home/gm4slv/6502/ca65src/src/monitor/monitor_dev.s)
Put the makefile in the same folder
put any source files to be included in the assembly process in the includes folder
- /home/gm4slv/6502/ca65src/src/includes/rtc.inc
- /home/gm4slv/6502/ca65src/src/includes/ioports.inc
make a build main folder /home/gm4slv/6502/ca65src/build/

The general tree:

/home/gm4slv/6502/ca65src/ = base folder for ca65 projects aka $CA65SRC

config files : firmware.cfg, cc65.rules.mk, tools.mk are in $(CA65SRC)
sources directory : src is in $(CA65SRC) → $(CA65SRC)/src
inside sources directory are build, includes and the individual project source directories. $(CA65SRC)/src/build/, $(CA65SRC)/src/includes/ and (eg) $(CA65SRC)/src/monitor/
inside each project source directory are the asm source file eg monitor_dev.s and a specific makefile

To include sources from the includes directory first define the variables, then the includes :

Variables

define zeropage variables:

.zeropage
 
DUMP_POINTER:     .res 2
FLAGS:            .res 1
TOGGLE_TIME:      .res 1
CLOCK_LAST:       .res 1
MESSAGE_POINTER:  .res 2
TICKS:            .res 4
CENTISEC:         .res 1
HUNDRED_HRS:      .res 1
TEN_HRS:          .res 1
HRS:              .res 1
TEN_MINUTES:      .res 1
MINUTES:          .res 1
TEN_SECONDS:      .res 1
SECONDS:          .res 1
MEM_POINTER:      .res 2

and define the other .bss variables:

.bss
 
INKEY:            .res 1
ASCII:            .res 4
BYTE:             .res 2
TENS:             .res 1
HUNDREDS:         .res 1
HEX:              .res 2
HEXB:             .res 2
TEMP:             .res 1
TEMP2:            .res 1

Then the includes

  .include "../includes/ioports.inc"
  .include "../includes/lcd.inc"
  .include "../includes/getkey.inc"
  .include "../includes/functions.inc"
  .include "../includes/rtc.inc"

make sure the include files have appropriate .code directive to put it in the right place when its all assembled together:

e.g. in functions.inc:

Tutorial Progress

A record of my progress through the Ben Eater You Tube tutorial

Day One : Tuesday 16/8/22

Kit arrived
Installed:
- CPU
- EEPROM
- NAND Gate
- Address & Data lines between CPU and EEPROM and address decoder for EEPROM
Used python “makerom.py” script to burn eprom:

rom = bytearray([0xea] * 32768 )
 
rom[0] = 0xa9
rom[1] = 0x42
 
rom[2] = 0x8d
rom[3] = 0x00
rom[4] = 0x60
 
rom[0x7ffc] = 0x00
rom[0x7ffd] = 0x80
 
with open("rom.bin", "wb") as out_file:
     out_file.write(rom)

ROM file hexdump:

00000000  a9 42 8d 00 60 ea ea ea  ea ea ea ea ea ea ea ea  |.B..`...........|
00000010  ea ea ea ea ea ea ea ea  ea ea ea ea ea ea ea ea  |................|
*
00007ff

Unable to confirm correct running - still waiting for Arduino Mega to act as a logic analyzer. LEDs on data or Address lines show activity….

Next stage

add the 65C22 VIA and use LEDs on output to show correct running

make an 8-bit binary counter with LEDs as an exercise

Day Two : Wednesday 17/8/22

Using Siglent Function Generator as the CPU PHI2 clock

added 65C22 VIA and 8 leds
much debugging of hardware/wiring - breadboard is a NASTY way of doing this…..!
- ordered some IC sockets & other hardware to allow me to build a version on Vero/perf board and move away from breadboard once I've got the the point in the tutorials where all the hardware is stable.
used python script to get the “01010101 → 10101010” LED sequence running.

Self-study

modified assembly code to make the LEDs flash in a binary count

8 bit counter

### 8-bit Counter
 
code = bytearray([
    0xa9, 0xff,         # lda #$FF
    0x8d, 0x02, 0x60,   # sta $6002 : put 11111111 into VIA's Port B control register - all port pins are OUTPUT
 
    0xa9, 0xff,         # lda #$ff (start with all LEDs lit)
    0x8d, 0x00, 0x60,   # sta $6000
 
    0x1a,                # inc A
 
    0x4c, 0x07, 0x80,   # jmp $8007
    ])
 
 
rom = code + bytearray([0xea] * (32768 - len(code)))
 
rom[0x7ffc] = 0x00
rom[0x7ffd] = 0x80
 
with open("rom.bin", "wb") as out_file:
     out_file.write(rom);

This assembles as :

00000000  a9 ff 8d 02 60 a9 ff 8d  00 60 1a 4c 07 80 ea ea  |....`....`.L....|
00000010  ea ea ea ea ea ea ea ea  ea ea ea ea ea ea ea ea  |................|
*
00007ff0  ea ea ea ea ea ea ea ea  ea ea ea ea 00 80 ea ea  |................|
00008000

LEDs flash in binary count to 255 and cycle round… endlessly.

16 bit counter

I wanted to see if I could extend the counter to 16-bits, using 2 VIA ports to drive the LEDs

To make life easier I moved to assembly language and the VASM assembler as recommended in the tutorial.

To count beyond a single 8-bit byte needs a way of holding 2 separate bytes of the count, the low byte and high byte, and only increment the high byte when the low byte rolls past 11111111. Tricky with no RAM installed yet.

I used the 2 index registers X and Y. The carry bit is set as a result of arithmetic on the Accumulator register, so X (low byte) has to be copied to the Accumulator for the addition of 1 each time round the loop.

        .org $8000
 
reset:
        lda #$ff
        sta $6002    ; set port B pins to all output
        sta $6003    ; set port A pins to all output
        lda #$00
        tax          ; X holds the low byte. initialize to zero
        tay          ; Y holds the high byte. initialize to zero
 
 
loop:
        txa          ; copy low byte to A
        adc #$01     ; add 1
        tax          ; copy new value to X
        bcs high_b   ; if carry flag set, branch to increment the high byte
 
 
print:
        txa          ; bring the low byte to A
        sta $6000    ; send low byte to Port B LEDs
        tya          ; bring the high byte to A
        sta $6001    ; send high byte to Port A LEDs
        jmp loop
 
high_b:
 
        iny          ; increment high byte in Y
        jmp print
 
        .org $fffc
        .word reset
        .word $0000

Assembled code

00000000  a9 ff 8d 02 60 8d 03 60  a9 00 aa a8 8a 69 01 aa  |....`..`.....i..|
00000010  b0 0b 8a 8d 00 60 98 8d  01 60 4c 0c 80 c8 4c 12  |.....`...`L...L.|
00000020  80 00 00 00 00 00 00 00  00 00 00 00 00 00 00 00  |................|
00000030  00 00 00 00 00 00 00 00  00 00 00 00 00 00 00 00  |................|
*
00007ff0  00 00 00 00 00 00 00 00  00 00 00 00 00 80 00 00  |................|
00008000

Add another 8 LEDs, to Port A, to show the High Byte….

It now counts to 1111111111111111 or $FFFF or 65535 as displayed by the LEDs attached to both VIA ports.

Next stage

is to add the LCD module in place of the flashing LEDs

Day Three : Friday 19/8/22

LCD

added the LCD module to the VIA output port(s)
put the “hello.s” assembled code into ROM
LCD printed Hello, w and no more….

8 Characters… what, why?

Lots of messing about with the assembler code to see if I could get all the Hello, world! message to print to the LCD.

By adding the necessary instruction to change the display position I could use all 16 characters of the display, but I couldn't get it to print all the message in one go…. The same happened with a different LCD module.

Eventually I checked, and re-checked, the address and data lines between CPU, ROM and VIA and must have re-inserted one that was loose. Afterwards the display showed Hello, world! correctly.

I assume the error was that an address line between CPU and ROM wasn't connected, so at one step of the program the ROM went to the wrong address and returned garbage data, and the program stopped, or just randomly stepped through the otherwise empty ROM?

Anyway, whatever the mechanism, ensuring all address & data lines were seated correctly cured the bug.

Next Stage

adding RAM
rebuilding on “properly wired” stripboard to remove the annoyance of breadboard wires coming adrift.

Day 4 : Saturday 21/8/22

added RAM
re-wrote “hello_world” to use 4-bit LCD addressing and moved LCD to PORTB of VIA, freeing up all of PORTA for other uses
began building veroboard version to

Day 5 : Sunday 22/8/22

Arduino Project

I dabbled with Arduino to build some small projects back in 2021, mostly using the SI5351 PLL chip.

A lot was learned from the You Tube channel, and blog, of Charlie Morris ZL2CTM

https://www.youtube.com/c/CharlieMorrisZL2CTM and https://zl2ctm.blogspot.com/.

I designed and built a 60m QRP SSB/CW/Digimode transceiver which started as a Direct Conversion DSB radio and then morphed into a superhet SSB rig with 9MHz IF and crystal filter. I was also was in the process of building a phasing RX and CW TX to make an HF CW transceiver - band TBC but it was working on 17m when I drifted off the path and abandoned radio for a while.

I've dug out the 60m rig and it's still working. I've got it in my new shack as a 60m monitor RX. One of its features is a “scanner” - just cycling around a selection of channels pausing for a second and moving on which is handy for spotting activity popping up on one or other channel.

Today I also went searching for the Arduino sketches for all my little experiments at the time, and found them on the old laptop I used in the shed-shack at the time. This laptop is physically decrepit - screen broken etc. - but can still be accessed over the LAN. I've retrieved all the sketches and they are linked at the bottom of the page.

It's been a while (5 years!) since I played with Arduino and the 5351 PLL, so I'm a little rusty, but I'm considering making a QRSS TX to run on 60m if I can find somewhere to put a small base-loaded vertical (perhaps a helical linear-loaded vertical?). The first step will be to write the Arduino sketch to make the 5351 make pretty patterns on a waterfall. Then a simple 500mW PA strip shouldn't be too difficult.

I still have some un-used Seeduino Nano boards and some 5351s, so I think I'll rig up a development board and start writing code. Small baby steps….

(I've begun QRSS MEPT )

Music - A Return To An Old Hobby

date: 2026-03-02 14:52

I used to play a lot of music - by this I mean actually play it myself, on instruments like mandolin, bodhran, guitar….

I first fiddled with guitar as a teenager. Badly. I had a cheap nylon strung “classical” guitar, and even for a while a very cheap and very, very nasty electric guitar.

When I went to University in 1984 I was already into folk music, as well as heavily into early Mike Oldfield. So I knew of the bodhran. I bought myself a basic model mandolin and found a guy who made bodhrans in a small workshop in Manchester. All I could afford was a very basic calf-skin bodhran but it was enough to get the hang of it.

I listened to a lot of Planxty, Bothy Band, Boys from the Lough, Andy Irvine etc. back then, all on vinyl. I still have the same vinyl albums and play them occasionally even now.

Here's a B&W photo of my stash of instruments from around 1986. I developed & printed it myself, using an enlarger a mate had borrowed & set up in the bathroom in his flat. I recently found the photo again, and put it in a clip frame and hung it in my den.

I later bought a better mandolin, and also got better goatskin bodhran from Hobgoblin Music.

I sold my 1st mandolin, and bodhran to a mate of mine. I think he still has them. I certainly still have my 2nd mandolin and bodhran.

While I was at UMIST, between 1984 and 1988 I used to drink in the Jolly Angler in Ducie Street. It was a backstreet Irish pub, but had no music session. I went to play pool with mates and drink copious quantities of Hyde's Anvil bitter (and at Christmas time their strong Winter Ale from a small barrel on the bar).

The landlord had a niece who at that time was doing her O levels and was struggling with maths. She was a mean piano accordion player too. We started a weekly maths tuition followed by a few tunes. I took my mandolin and she took her PA.

After a few weeks of this a few customers asked

“is this a regular session?”

“no, just us having a few tunes”

“is it ok if we join in next week? There's no good session on a Thursday nearby”

“ Yeah! that'd be fun”

and then it exploded from there.

More and more and more people came on a Thursday night. After only a few weeks I found I was well out of my depth, and stopped playing, or trying to play. I'd learned a few new tunes in the first few weeks of the session but then found all I could do was sit and watch and listen.

But I still played mandolin for my own amusement. I wasn't particularly good, but I enjoyed it.

There have been various instruments over the years since then.

Later, after leaving UMIST and getting a job I bought myself a bouzouki from Hobgoblin too.

My parents had found an old Hohner Double-Ray Black-Dot in B/C at an antiques fair which I later bought by visiting the guy's house in Cramlington (nr. Newcastle) while we were visiting.

The story of this is on my old, old website which I recently uncovered…

https://g4slv.info/website/pages/music.htm

I then bought a 2nd hand Saltarelle “Le Bouebe” melodeon in D/G in around 2002, and later a Castagnari Lilly melodeon for my 40th birthday in 2006. I later sold the Lilly, as I wasn't playing it enough to justify keeping it.

I still have the Saltarelle. But I rarely ever take it out and play it any more.

Here's an old photo of me in the Westings, Shetland.

I got to be “ok” on melodeon - but nothing better then “ok”.

In fact I've never got better than “ok” on anything, in the 45+ years of my trying to play.

I didn't have a guitar for several years and during Covid lockdown in 2020 I bought a cheap classical guitar (Yamaha C40) and spent a lot of time while isolated at home trying to learn proper classical guitar. I followed some of the excellent courses by Bradford Werner https://www.thisisclassicalguitar.com/start-here/. When life returned to normal I stopped studying, but I'd already found some physical problems with my wrists and hands due to the Rheumatoid Arthritis. I still noodle on the guitar, but I can't see me being able to really immerse myself in learning it properly.

I also bought a Treble Recorder last year and then neglected to do anything about it. I'd played Descant Recorder as a primary schoolboy aged 10 or so. That's where I learned to read music. So the Treble Recorder was supposed to be my way of reconnecting with the fun of learning a new (and at face value fairly simple) instrument. Of course the Recorder is a vastly under-rated instrument capable of magical sound when played by an expert.

I recently found some old mp3 recordings I'd done in around 2002, in a zip file which contained the HTML and other files from a website I had back then. There were 4 mp3 files that had me playing mandolin, and bodhran (and guitar, out of tune)

They are badly recorded - from memory I did it by using a pair of cheap stereo headphones as a microphone (!) and recording using grecord on a linux box (an old Gnome app for simple sound recording - probably running on Red Hat 6?)

To multi track I'd play the 1st recording back from the speakers on another linux box while recording the 2nd track (and the playback of the 1st which was audible in the background….) and I'd repeat this again to get a 3rd track.

The are in https://g4slv.info/website/pshed/ and these are the links to the files

The future?

So, now, at 60 years old I'm wondering what to do with myself. What hobby to persue. How to find joy and fun again.

I found myself looking up at my mandolin a few nights ago, thinking *“I wonder if I remember any tunes?”* and I took it down from its hanger. And 2 hours later I forced myself to put it down & go to bed….

I've been a little lost recently, not knowing what to do with my spare time. Perhaps this is the answer. Just enjoy playing music for my own amusement again.

Privacy ?

Private versus Public

I recently got totally fed-up with the state of *the internet*. Mobile phones so tightly tied to *Google* or *Apple* that they track your every move and communicate every action you make online with databrokers that use this to profile you and target ads (and worse?) at you….

Why isn't it possible just to use a phone to make phone calls, send text messages, and to innocently and privately look at websites?

De-Googling etc.

I started *de-googling*[^1] as far as I could. And this included my *desktop* interaction with the web too. I'd already been using adblockers for years, but this time I went further.

And I found it's *impossible to fully de-google*.

Of course I *knew* this - after all, Android *is* Google. And the web *is* Google.

But I made tiny first steps. Why do I need accounts with Google and other major enshitifiers to do the things I still enjoy online? This feeling also tied in with a desire to cut-back on online shopping (I'll do a post on my *no-buy* aspirations another time) so I got rid of other accounts too.

I got rid of my accounts with (at least these, probably others that I've forgotten about):

Google
- My You Tube Channel was deleted too
Microsoft
Amazon
Paypal
eBay
Reddit

I didn't have *Facebook* or *Twitter/X* or *Mastodon* or *Instagram* or *Tik-Tok* or any other *social media* accounts, so there was no FOFOMO[^2] to worry about.

#### A quiet online life?

This still means I can use the internet but reduces the level of *integration* which happens - where everything talks to everything else *via Google*.

#### To properly de-Google?

After doing as much as I could with my stock Android phone I ran into the usual problem of how tightly integrated even the simplest of apps is with the Google eco-system and that it didn't seem possible to use a *normal* Android phone and at the same time to be invisible to Google & to escape its spying.

A fully de-googled-at-source-android was the answer. There are a few options. I won't go into them in detail, I just took the easiest route.

I bought a Fairphone6 pre-installed with /e/OS.

I tried it first *without* running *micro-G* (which spoofs some of the functionality of *Google Play Services* etc. and which gives access to certain Google services anonymously so that the apps that rely on some Google functionality can still be installed and will run).

But that limited my options for apps.

So I enabled *micro-G* and installed a *very small number* of non-FOSS Android apps:

2 Banking apps for my personal and business bank accounts
BBC Sounds - but only because *I can't abide adverts* even in podcasts - and the BBC is the only source I can trust not to shove commercial adverts at me during podcasts
Canon Print - to access my little Canon Selphy printer (yes, it is possible without the Canon Print app, but it's fiddly and error-prone)

And that's all.

Everything else is either the pre-installed version from /e/OS or it's a FOSS version from *f-Droid*

/e/OS has a built in system-level tracking blocker which circumvents the many (many) *phone-home* tracking messages that these non-FOSS apps send to various analytic/tracking providers. It's quite scary to see just how chatty these apps are, and how many external 3++rd++ party tracking services are fed data - quite separately from the actual application's useful and necessary network traffic (this still flows and allows the app to function normally).

#### Privacy - hiding from real people on the internet

I took things a step further - and tried to extract myself from *any online activity* which would involve showing anything of mine to *strangers on the internet*.

I made my [Commonplace Wiki](https://g4slv.info/dokuwiki/) private - nothing was readable by passing strangers.

I'd deleted my You Tube stuff already, as a part of *de-googling* so that had already been taken care of.

I started to delete various accounts that I had on web-forums, and thus my old posts disappeared too (I don't contribute much, and my words are unlikely to be missed by anyone).

I wanted to *disappear* from the online world.

I know it's not possible to remove all traces of your past online life - but I wanted my future involvement with the web to be invisible.

#### The Hypocrisy of this

But I was still reading *other* people's websites and blogs. Watching other people's You Tube videos - but *not-logged-in* and via a browser with an *adblocker* (or more often via `NewPipe` or by downloading the video to my laptop 1++st++ by using `yt-dlp`)

I was *consuming* but not *contributing*

This seems selfish and petty.

So I un-hid my dokuwiki site, and it's now readable by anyone. I don't know if anyone finds any of it useful, it exists mainly for me to have a place to store *useful-to-me* information.

I figure though that it's *good* to share stuff online (even when there are probably very few people that'll ever read it). But, because *I* find other peoples' stuff useful, interesting etc. then should I not let other people make up their own minds about my stuff? By at least making it accessible.

The important thing to me now is that this sharing *must be done without involving the enshitifying platforms* like *Google*, *Meta* etc. etc.

I *can* share my thoughts, experiments, notes etc. with real people on the internet - but only by hosting it myself.

This can be done with a blog (like this one) or a wiki like [this one](https://g4slv.info/dokuwiki/doku.php?id=start) and even with an old hand-built plain html website from more than 20 years ago, like [this one](https://g4slv.info/website/index.html) which I used to have back in the early 2000's and which has been languishing in a zip file for many years.

#### Blogging in 2026

After deciding that I don't want to hide from *real* people, that the internet is (still) a good thing when used for good reasons. It allows us to share with other *real* people. Enshitification has largely spoiled the *mainstream* web, but there are still lots of personal web sites, blogs, wikis etc.

Let's keep them going.

This is why I'm blogging now. It's been a few years since I last did any blogging, but I think I can enjoy it again (regardless of the number of readers) and create a small corner of the internet out of my own head. It might be self-indulgent twaddle, it might be pointless and meaningless and if *I* get some happiness out of making it, that's enough. But it *has* to be online and *has* to feel like it's a small fight against the enshitification that the major platforms have wrought on the once wonderful web.

[^1]: I use this as a generic term for *cutting out as much surveillance and tracking as possible* [^2]: Is this a new coining? Fear of FOMO The fear that I'll suffer *“Fear of Missing Out”*

Fingerprinting

Each calculator handles the calculation of functions (SIN, COS etc) differently - different algorithms, different degrees of precision etc.

One way of spotting similar underlying hard/firmware is to carry out a fixed chained calculation on each calculator and to observe the result.

One common test is a sequence of SIN COS TAN ATAN ACOS ASIN on a relatively low starting number - such as 9

9SINCOSTANATANACOSASIN gives a number (hopefully) very close to the starting value of 9 - and the variance from 9 is a fingerprint that can be used to spot similarities between different models.

I also found a different version of the same idea at https://tangentsoft.com/rpn/wiki?name=Ballpark+Accuracy#results

Instead of subtracting 9 from the result this test divides the result by 9 and then finds the LOG₁₀ of this fractional error

9SINCOSTANATANACOSASIN 9 / LOG

Here are some of these results

Notes

Complex Numbers

For more about the 41Z see the separate page DM41X 41z Module

I'm using the 41Z complex number module by Angel Martin to add a 4-level complex number stack. It's a bit confusing at first to get to grips with, but adds a lot of functionality to the the DM41x.

After a bit of trial and error (this is my first play with a “plug-in module” after all) I discovered the simplest way to make the keyboard function normally, and get easy access when needed to the complex functions, was to assign a USER key (usually the statistics summation key ∑+ to the 41Z module function ∑ZL.

Each press of ∑+ now temporarily modifies all the keys to access specific 41Z functions. The functions available are extensive, through the use of the SHIFT key and by multiple presses of the ∑+ (henceforth referred to as Z) key.

I drew out a diagram to show the various functions available.

Once a selection is made the keyboard switches back to its normal behaviour, so all the usual functionality is available.

Most of these are unlikely to be used often - and it's also possible to make a much narrow selection of 41Z functions and make your own USER assignments, rather than use the ∑ZL keyboard - although this might mean you block access to inbuilt functions you might want - which would mean switching out of USER keyboard mode at times. At the moment the ∑ZL option seems the most versatile.

Many of the 41Z functions available are beyond my pay grade and unlikely to ever find a use, but the Complex Keyboard still makes things much easier to deal with.

For example the two keypresses:

Z 1\x

is much easier than the 7 it would otherwise need to invert a complex number

XEQALPHAZINVALPHA I need to practice finding the right function (the main ones printed on the keyboard as well as the new ones provided by 41Z's ∑ZL keyboard, but my fingers are slowly starting to move in the right direction.

One thing I do notice, though, as that due to the need to press various keys (XEQ, ALPHA, SHIFT etc) it's sometimes possible to make a real mess if you miss a vital key in the middle of entering lots of data & instructions and find your stack totally screwed up, or several lines of program code full of nonsense….

I'm sure it'll all become second nature soon enough.

HP16C Emulator module

This is another interesting module to add the functionality of the HP16C - the Programmer's Calculator designed to handle calculations in various mathematical bases as used in computer programming and networking : Binary, Octal, Hexadecimal and Decimal. I adds much more value than the rather basic functions in the Advantage Pac module.

After much trial and error I found a combination of HP16C module and Library 4 library that worked correctly. The HP16C module needs the Library 4 module, but I found some problems with different versions. Using the versions contained in the Swiss Micros package had a weird bug - the 16* (multiplication) function simply didn't work. I found a post by Angel Martin on the HP Calculator Forum with a ZIP file containing the 2 modules that worked correctly.

Here is the zip file : hp-16c_rev.1a.zip

I'll make a separate guide to using the main features here DM41X HP16C Module

Sandbox Server

UPDATE — John Pumford-Green 04/03/25 08:02 GMT

The hardware running this little machine has recently become unreliable, the SSD is dying, so I've turned it off. I'll leave any old information about this box for future reference

UPDATE — John Pumford-Green 27/04/23 06:16

I have removed the self-signed SSL configuration on the shack sandbox server and reverted it to plain HTTP. I may re-instate it at some point in the future, but I decided I didn't want the hassle of persuading Chrome to accept the self-signed unsafe certificate all the time.

The details below show how it was originally set up, and can be used in future should I decide to repeat the process.

Encryption

The shack webserver has a mirror of my real dokuwiki, to use as a test-bed and after setting it up I discovered that the encryption plugin I was using on the real wiki Encrypted Passwords Plugin didn't work.

After some head scratching, and after trying out another plugin (dokucrypt2 plugin), I figured out the difference between the 2 web servers….

The real server is configured to do proper HTTPS, with a real, signed SSL certificate. The shack server only does plain old HTTP, no encryption.

To test out my theory that this is what was breaking Encrypted Password Plugin I setup self-signed SSL on the shack webserver. It's just for local testing so there's no need for traceable certification, just the ability to handle HTTPS traffic.

It turned out to be quite simple….

I found the information here : https://www.digitalocean.com/community/tutorials/how-to-create-a-self-signed-ssl-certificate-for-apache-in-ubuntu-16-04

gm4slv@shack:~/ssl_setup$ sudo openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout /etc/ssl/private/apache-selfsigned.key -out /etc/ssl/certs/apache-selfsigned.crt
Generating a RSA private key
.......................+++++

writing new private key to '/etc/ssl/private/apache-selfsigned.key'
-----
You are about to be asked to enter information that will be incorporated
into your certificate request.
What you are about to enter is what is called a Distinguished Name or a DN.
There are quite a few fields but you can leave some blank
For some fields there will be a default value,
If you enter '.', the field will be left blank.
-----
Country Name (2 letter code) [AU]:GB
State or Province Name (full name) [Some-State]:Shetland
Locality Name (eg, city) []:Clousta
Organization Name (eg, company) [Internet Widgits Pty Ltd]:GM4SLV
Organizational Unit Name (eg, section) []:GM4SLV
Common Name (e.g. server FQDN or YOUR name) []:shack
Email Address []:

The certificates are put in the directories already pointed to in the default SSL site config file so all I had to do was tell apache to enable ssl

sudo a2enmod ssl

and enable the default SSL site

gm4slv@shack:/etc/apache2/sites-enabled$ sudo a2ensite default-ssl.conf
Enabling site default-ssl.
To activate the new configuration, you need to run:
  systemctl reload apache2
gm4slv@shack:/etc/apache2/sites-enabled$ sudo service apache2 restart

SSL enabled

Browse to https://shack/dokuwiki and I got the usual dire Chrome warning

…. but chose to continue anyway…

and it works!

Encrypted Password Plugin

Then I tested the Encrypted Passwords Plugin and it also works

UPDATE— John Pumford-Green 31/05/22 21:13

The plugin page does say that HTTPS is needed:

Please note that the modern encryption mechanisms used within this Plugin require a modern Browser, JavaScript enabled and a wiki served via HTTPS!

Result!

I can now use the sandbox wiki to test everything that's running on the real wiki server.

Redirect to https

(UPDATE — John Pumford-Green 31/05/22 10:08)

edit

/etc/apache2/sites-enabled/000-default.conf

to add

ServerName gm4slv.plus.com
Redirect permanent / https://gm4slv.plus.com/

Open & forward router's port TCP/443 to the shack webserver

sudo service apache2 restart

Hey presto - external access to HTTPS

Diversion into the Linux Serial Console...

Diversion into the Linux Serial Console...

— John Pumford-Green 01/10/22 22:26

In preparation to my plan of adding a pair of RS232 serial ports to the next iteration of the 6502 computer I dug out an old Wyse serial terminal to use. I thought I'd check it still worked after many idle years gathering dust. It was last used when I first started playing with Linux on an old 486/DX2 machine (Red Hat 6 I think) and used it to access the headless 486 machine through a serial console.

To re-live the experience I hooked it up to my little “pico-ITX” Linux server, which has a real serial port with a 9-pin D connector (!) and set about configuring Debian 11 with systemd (urgh!) to provide a console and login on /dev/ttyS0.

Linux Serial Console

Then I remembered using Pine as an email client via a terminal session (and in xterm windows, and a non-X linux virtual terminal) so I thought I'd install it and re-live those days. Pine is no longer (easily) available but a new version is still being maintained - Alpine

Installed it and spent a happy evening getting it to work with 2 different IMAP accounts (and the correct SMTP servers) Old stuff but good

And then, telnet and telnetd….. and ftp and ftpd….. oh, those were the days..!

I wanted to install and run slrn for USENET NNTP news, like the old days, but I discovered there was no point even trying, as there seems to be no freely available NNTP servers around any more. Back in the day most ISPs seemed to provide a server even if it was limited in the newsgroups it carried. That doesn't seem to be the case any more.

On the subject of Wyse terminals and Linux I stumbled on a You Tube video https://www.youtube.com/watch?v=xQTr9ZOJkC0&feature=share&si=ELPmzJkDCLju2KnD5oyZMQ and this led to another interesting video https://www.youtube.com/watch?v=NUmTaRu6o8g&feature=share&si=ELPmzJkDCLju2KnD5oyZMQ describing a console-mode RSS reader Newsboat so I had to try it….

I've enabled the RSS feed from this dokuwiki WiKi/Blog, just to play…. point your RSS software at https://www.gm4slv.org.uk/dokuwiki/feed.php

Well, now I've got Alpine, Lynx and Newsboat running in a Tmux session, accessed from a nice amber glowing CRT with the Wyse-185.

Now I need to build Mk2 of the 6502 - which is going to be wire-wrapped and much more compact than the rat's nest of Mk1

SSL Install on VPS

SSL Install on VPS

I decided to bite the bullet and obtain an SSL certificate and install it on this VPS, and configure Apache2 to use HTTPS instead of plain HTTP.

I used Fasthost again to obtain the SSL certificate, and some of their instructions were a little dodgy regarding the steps to install it and get Apache to work with SSL. I managed in the end though.

gm4slv.org.uk now has a SSL certificate and connections to port 80 HTTP will be automatically redirected to port 443 HTTPS.

The steps with Apache (ignoring the process of obtaining the certificates):

There are 3 certificate files:

*.key is generated on the VPS itself with

openssl req -new -newkey rsa:2048 -nodes -keyout gm4slv.org.uk.key -out gm4slv.org.uk.csr

the signed *.crt file obtained from the signing authority via FastHost (it's the gm4slv.org.uk.csr key signed by the authority's key)
the “intermediate” file obtained from the signing authority via FastHost (this is the “chain of authority” file?)

Once the keys are to hand:

copy the 3 certificate files to a directory on the VPS. I used /usr/local/ssl/
tell Apache where to find the keys:
- add to default-ssl.conf virtual host site file
  - SSLCertificateFile /usr/local/ssl/signed.crt
  - SSLCertificateKeyFile /usr/local/ssl/gm4slv.org.uk.key
  - SSLCertificateChainFile /usr/local/ssl/ca.pem
add ssl mod to Apache:
```
 a2enmod ssl 
```
make symbolic link in sites-enabled pointing to sites-available/default-ssl.conf
restart apache
open VPS firewall port 443 in FastHost control panel
browse to https://gm4slv.org.uk

set up redirect of plain HTTP to SSL HTTPS by adding to 000-default.conf

    ServerName gm4slv.org.uk
    ServerAlias www.gm4slv.org.uk
    Redirect permanent / https://gm4slv.org.uk/

restart apache

Unison

Unison

I used unison previously to maintain sync/backup of files between machines on my own LAN.

This has been used to keep files on a PC synchronized to the Dropbox folders on another PC, and thereby with the Dropbox cloud.

Now that I have access to a remote Debian Linux VPS machine I thought I'd revisit the use of Unison to keep folders synchronised - perhaps to keep a remote backup of certain files.

You can never have too many backups

I installed the Debian package of unison on the new VPS machine and made a matching pair of configurations - one on the VPS and one on the Shack Laptop (which already has unison installed).

The configurations:

Laptop

root = /home/gm4slv/test_dir
root = ssh://gm4slv.org.uk/test_dir
sshargs = -C

VPS

root = /home/gm4slv/test_dir
root = ssh://gm4slv.plus.com:27659/test_dir
sshargs = -C

Unison version

I put some files in one “test_dir” and ran

unison vps

from the Shack Laptop and got this:

Unison 2.51.3 (ocaml 4.11.1): Contacting server...
Fatal error: Received unexpected header from the server:
 expected "Unison 2.51 with OCaml >= 4.01.2\n" but received "Unison 2.48\n\000\000\000\000\017",
which differs at "Unison 2.4".
This can happen because you have different versions of Unison
installed on the client and server machines, or because
your connection is failing and somebody is printing an error
message, or because your remote login shell is printing
something itself before starting Unison.

Incompatible versions. Laptop is running Debian 11 “Bullseye” and the packaged version of Unison is 2.51.3, whereas the VPS machine is running Debian 10 “Buster” and that has Unison version 2.48.

I've had this happen before, Unison is very touchy about having the same version at both sides.

I removed the older 2.48 from the VPS and downloaded a matching V2.51.3(ocaml 4.11.1) from github:

https://github.com/bcpierce00/unison/releases/tag/v2.51.3

Unpacked and moved unison to /usr/local/bin on the VPS.

Success

Now I was able to sync between the machines.

Adding the SSH public keys from both machines to the '~/.ssh/authorized_keys2'' of its peer meant it all went ahead without password prompting.

Now I have two “mirrored” directories on two separate machines I can use the VPS as a low-key remote file store.

Dokuwiki & Encryption

anonymous@undisclosed.example.com (Anonymous) — Thu, 04 Jun 2026 07:18:42 +0000

Dokuwiki & Encryption

I'm now using the encrypted passwords plugin to encrypt sensitive information on dokuwiki pages. This plugin has the advantage that the encryption used can be decrypted outside of Dokuwiki (e.g. if I can only get hold of the raw text file from a backup) via openssl.

An example of off-line decryption - I copied the encrypted text from a dokuwiki page and pasted it into the echo command below. At the openssl password prompt I entered the password used to encrypt and out popped the clear text this is an encryption test

gm4slv@gm4slv:~$ echo 'U2FsdGVkX1/oih+ShQJ/EcEaeOk4JVl4IU2FI1d35A/jAsfy/2nwGbcLEEgABjQf' | openssl base64 -d |openssl aes-256-cbc -d -pbkdf2
enter aes-256-cbc decryption password:
this is an encryption test

The plugin is documented here:

https://www.dokuwiki.org/plugin:encryptedpasswords

(UPDATE — John Pumford-Green 30/05/22 16:48 )

I found the encrypted passwords plugin didn't work on the sandbox wiki installation. The only difference I can see is that the sandbox uses PHP7.4 rather than PHP7.3 on the production webserver.

I've installed the dokucrypt2 plugin https://www.dokuwiki.org/plugin:dokucrypt2 on both machines and it works on both.

I'll have to de-crypt the original encrypted pages and re-encrypt them using the dokucrypt2 plugin if I want to access them on the sandbox machine, but that's not too difficult to do, there's not much encrypted information (yet).

(UPDATE — John Pumford-Green 30/05/22 19:43 )

I solved the issue with the sandbox server - it needs to be enabled for HTTPS (SSL) for this plugin to work.

I installed a self-signed certificate and set up SSL for the shack's webserver as detailed here: Sandbox Server and the original plugin works. Which is good, because I preferred it to the dokucrypt2 plugin.

Update July 2022

I've modified the server/client code to create a single-radio AR7030 control program that gives access to IF filter, and reads s-meter etc.

New (July 2022) version of Tkinter GUI with S-Meter graph and IF filter Selection

Icom IC-706

anonymous@undisclosed.example.com (Anonymous) — Thu, 04 Jun 2026 06:39:56 +0000

←Rig and Key List

Icom IC-706

Mark 1 - the original “Shack-in-a-box”

HF 100W
6m 100W
2m 10W

Background

From the Silent Key equipment of Peter GM0CXQ

First impressions

In poor condition cosmetically, internally and externally
Intermittent RX performance on several bands, most severely 6m, due to LPF switching relays
No Power cable
- ordered via eBay 24/5/23
No microphone
- ordered via eBay 25/5/23
Not “MARS” modified → no TX on 60m

Initial tests

Sensitivity ok on all HF bands
6m shows intermittent “deafness” after changing bands - LPF relays?
Initially some higher HF bands also showed slow decrease in sensitivity after a few minutes. After transmitting a few times on each band this tendency stopped - have the LPF relay contacts “wiped” themselves clean by carrying more significant signal current on TX?
- 6m still suffers random RF signal loss on RX
TX power ok on all HF bands, and 6m, with 100W FM carrier at setting “H”
All controls work correctly
Fitted FL-223 “Narrow SSB” filter option appears to work (TBC)
Frequency calibration not checked but appears to be acceptable.

Repairs and Modifications

Cleaning

All knobs removed and washed in warm soapy water and all grooves in knobs scraped clean with toothpicks.
Front Panel cleaned, all recesses around buttons/controls cleaned with toothpicks and warm water (being careful….)
Covers from main unit removed and washed to remove build up of dirt from inside and outside.
Inside of main unit vacuumed and blown to attempt to remove as much loose powdery dirt deposits as possible without damaging any connectors or components. Some cleaning of surfaces done where possible.
Re-assembled

6m LPF relays

To cure signal loss on RX I removed the LPF board and was able to pop the clear plastic tops from the 2 relays, used on either side of the 6m LPF section.
Contacts in RL2 and RL3 were cleaned with Contact Cleaner spray, and wiped with paper soaked in cleaner, to remove any dirt/contamination build-up.

Tops replaced on relays and LPF board replaced into radio.
Receive sensitivity now good and does not vary with time, or following band changing.
The relays used on the other HF bands are of a different (more easily sourced) type and can't be opened in this manner. Fortunately they all seem to be healthy at the moment.

MARS TX Mod

To allow use on the 60m band I carried out the simple modification to remove “D59” from the Main PCB, which removes the “TX only in Ham Bands” restriction.
Radio now transmits across the whole HF band, including 60m

Signalink USB

For Digimodes using fldigi and a Signalink USB soundcard requires a simple Cat5 ethernet cable to connect the IC-706 Mic socket to the Signalink USB soundcard. The Jumper information is here : https://tigertronics.com/sl_wirebm.htm

Rigctl / Hamlib

Connect serial RS232 from laptop to IC-R75 and then C-IV cable between IC-R75 and IC-706. The IC-R75 will convert between RS232 and C-IV. Separate C-IV hex addresses means each radio can be addressed individually through one serial connection (/dev/ttyUSB0)

rigctl -m 3009 -s 9600 -r /dev/ttyUSB0

CCIR493 Selcall - 2026

anonymous@undisclosed.example.com (Anonymous) — Mon, 08 Jun 2026 17:46:06 +0000

←Radio Topics

CCIR493 Selcall - 2026

I am tempted to revisit my previous experiments with CCIR493 selcall. There's a page giving details and info of what I've already done with HF Selcall here

Today (June 6^th 2026) I saw a Mastodon post from Peter OE1LFB https://mastodon.radio/@oe1lfb showing a new Codan Envoy, and an idea sparked that perhaps there were other active Selcall users around. I sent a Mastodon post offering to try CCIR493 selcall but Peter informed me that the Codan was “..being used with the Austrian Red Cross, for emcom.”

But the idea took root anyway and I dug out both my Jenal SC2 microphones.

I initially connected one to my Xeigu G90, via its rear panel “data” connector and this seemed to work well. To properly test I wired the second SC2 to a mic plug for my Icom IC-7200.

I now have two separate HF Selcall transceivers. I put them both into dummy loads and tried various selcalls, beacon and beacon-99 calls between them. All working correctly.

In the past I've done selcall tests with a couple of stations - GM4WMM and F6EMT. I need to think about what to do this year as a mini-project.

Peer Tube Video

I've put a rambling video on Peer Tube : https://makertube.net/w/kPHwY1jNVMrH4fxvzHKhuN

When not otherwise being used I'll try to leave the IC-7200 monitoring one of these frequencies (all USB) with Selcall ID 3657

60m : 5371.5kHz
40m :
30m :
20m : 14343.0kHz
17m : 18163.0kHz
15m : 21427.0kHz
12m : 24977.0kHz
10m : 28305.0kHz

I plan to take the G90 and its selcall mic to various portable locations and test the path back to my home station using selcall beacons.

If anybody has the ability to use Barrett/Codan/CCIR493 selcall on HF and would like to try some tests and perhaps set up a net or sked please let me know! My email address is on the home page of this wiki, and is on my G4SLV @ QRZ.com page.

I have also been thinking about an “Engineer Order Wire” back-channel using Allstar for co-ordination and discussion of HF tests. I'll write a new Allstar wiki page about my new Allstar setup but in the meantime - I'm at Allstar node 481483. I don't monitor 24/7, but try to keep an ear on it while I'm near the shack.

6502 Setup

anonymous@undisclosed.example.com (Anonymous) — Tue, 30 Dec 2025 09:55:07 +0000

←6502 Project

6502 Setup

Various pre-requisites

Vim Syntax Highlighting

To get better syntax highlighting for 6502 assembler I found a vim syntax file asmM6502.vim

https://github.com/jestin/asmM6502.vim

This was saved as ~/.vim/syntax/asmM6502.vim

To make sure assembler source code used the 6502 syntax add:

autocmd BufRead,BufNewFile *.s,*.asm,*.inc set filetype=asmM6502

to ~/.vimrc

Vim in action

Assembler compiler VASM

To compile source to machine-code suitable for blowing onto EEPROM use the vasm compiler

It's possible to self-compile VASM by downloading the source-code from:

http://sun.hasenbraten.de/vasm/

but there are ready made binaries here, specifically for the 6502 old-style binaries:

http://www.compilers.de/vasm.html

Use the link at the foot of the page:

http://www.ibaug.de/vasm/vasm6502.zip

Download, unzip (extracts the files needed into ../vasm6502_oldstyle/linux/)

sudo cp ./vasm6502_oldstyle/linux/* /usr/local/bin

Add an alias to ~/.bashrc

←Arduino Projects

60m Transceiver

The 60m transceiver has the following features, which vary according to the loaded firmware

Channelized operation
LCD display
- Frequency
- Mode (SSB / CW)
- Modulation Source (Mic/Key/Data)
- RX / TX status
9MHz IF with Xtal filter
SSB & CW set via mode switch
Approx 3W PEP
Digital mode input/output and PTT via 9-pin D
SSB Mic input via 8-pin round “Icom” connector
Modulation Source (Mic or Data) can chosen via select switch
Scan start switch - scan a preset group of channels - cycles continuously, no “squelch”
- Use of Jenal SC2 CCIR493 Selcal microphone can be supported - including scanning

Arduino Versions

There are several different firmware versions….this is just a sample…

RX Only, with SSB, CW & scan

Audio levels

Devcal

Use the devcal program to set RX and TX audio levels.

This allows adjustment of alsamixer settings and then for fine tuning adjustment of PRE-AMP (for RX) and MASTER GAIN (for TX) config options to set the correct audio level INPUT on RX and deviation on TX.

Once the correct PRE-AMP or MASTER GAIN values have been determined in DEVCAL they are added to the relevant sections in svxlink.conf

To use DEVCAL first sudo killall svxlink

For Receive audio input:

sudo devcal -r -m=3000 -d=3000 /usr/local/etc/svxlink/svxlink.conf Rx1

Inject a signal to the radio @ ±3kHz deviation Adjust audio input level via

radio volume control
alsamixer Mic Capture level
devcal +/- to adjust PRE-AMP setting

until the displayed deviation agrees with the input signal's deviation.

Quit devcal

Transfer the displayed PRE-AMP value to the conf file.

For Transmit audio output

Monitor TX deviation

sudo devcal -t -m=3000 -d=3000 /usr/local/etc/svxlink/svxlink.conf Tx1

Toggle TX with T

Adjust

Alsamixer output
devcal +/-

to achieve ±3kHz TX deviation.

Turn off TX with T

Quit devcal

Copy the displayed MASTER GAIN value to the conf file.

sudo alsactl store

to save current mixer levels.

To prevent Echolink incoming connections while a Talkgroup is active

Uncomment :

proc tg_selected {new_tg old_tg} {
  puts "### tg_selected #$new_tg (old #$old_tg)"
  # Reject incoming Echolink connections while a talkgroup is active
  if {$new_tg != 0} {
    setConfigValue "ModuleEchoLink" "REJECT_INCOMING" "^.*$"
  } else {
    setConfigValue "ModuleEchoLink" "REJECT_INCOMING" "^$"
  }
}

in /usr/local/share/svxlink/events.d/local/ReflectorLogic.tcl

<svxinstall>/events.d/local/

Here are the 3 files containing tweaks to the standard behaviour.

Editing the original files (in events.d/) would work, but would get overwritten if the software is upgraded/re-installed. Putting local copies in events.d/local means the changes survive upgrades etc.

The actual path is:

/usr/local/share/svxlink/events.d/local/

I'll try to document what is different once I refresh my memory.

svxlink hotspot

anonymous@undisclosed.example.com (Anonymous) — Thu, 04 Jun 2026 06:39:56 +0000

←SVXLink

svxlink hotspot

Hardware

Platform	Raspberry Pi
Software	SVXLink
Interface	CM108 soundcard
Radio	IC-2E

Background

Remote/portable personal node.

Similar setup to MB7AZE but without the connection to Echolink and monitoring fewer TalkGroups. I use TG 8 as a testing ground to keep my traffic off the rest of the system.

UPDATE — John Pumford-Green 03/06/22 17:57

Making it into a mobile hotspot/echolink node/SVXreflector/parrot….

Svx Mobile

Networking

Usual method of deployment is to use a small MiFi 4G router as an access point to let the Raspberry Pi reach the internet. When this MiFi router is in use the node is on an inaccessible network and I can't reach it to make changes or shut it down.

The answer is SSH Tunnels

I use a “Remote SSH Tunnel” to get access to it from my home LAN.

The idea is that the remote node makes an outgoing SSH connection, to a machine on my LAN. I have an open port in the router forwarded to an internal machine for SSH access when I'm away from home. This is straightforward, and the remote Pi can easily create a SSH session on to my PC in the shack.

ssh -p xxxxx my.external.host.name

Along with this incoming SSH connection from the remote node is also a request to set up a “Remote Tunnel” which makes the internal Shack PC set up a listening SSH port. After this is done, any connection to this new listening port will be sent backwards to the remote node, tunnelling within the existing SSH connection.

This tunnel will now accept incoming connections from machines inside my LAN and forward them to the remote node. I can now effectively SSH to the remote SVXLink node as if it were on my LAN in the shack.

The magic is all done in SSH, but to make it more robust I use a package called autossh which is a wrapper around SSH that monitors for loss of the tunnel connection and initiates a new connection automatically if it should fail for any reason.

Here is the script that fires it all off:

tunnel.sh

#!/bin/bash
 
autossh -M 20000 -N -T gm4slv_tunnel

Simple enough, but effective.

The gm4slv_tunnel is connection defined in .ssh/config as:

Host gm4slv_tunnel
	HostName gm4slv.plus.com
	User gm4slv
	Port xxxxx
	RemoteForward 4446 localhost:22
	RemoteForward 8080 192.168.0.1:80

This sets up a remote tunnel, listening on port 4446 of my shack PC that will be forwarded back up the SSH connection to the SVXLink Raspberry Pi. It also sets up a listening port 8080 which gives me http access to the 4G MiFi router at the remote site in case I want to shut it down or reboot it or whatever. I just browse to http://my_shack_pc:8080 and I'm actually logged into the MiFi router. Magic!

etc/ssh/sshd_conf needs to have Gateway Ports yes to allow the Shack PC to accept connections to its new remote listening ports (4446 for SSH and 8080 for HTTP) from other LAN machines, otherwise these ports would only be accessible to the Shack PC itself (on “localhost:4446” or “localhost:8080”)

To allow an unattended/automatic login from the remote Raspberry Pi to the Shack PC it's necessary to set up public_key authentication and to have a passphrase-less key on the Raspberry Pi.

Generate a public/private key pair on the Raspberry Pi with ssh-keygen and don't enter a passphrase before saving it in .ssh/id_rsa and .ssh/id_rsa.pub. Then transfer a copy of .ssh/id_rsa.pub from the Raspberry Pi to the Shack PC and put it in the authorized_keys2 file:

(on Raspberry Pi):

$ scp .ssh/id_rsa.pub user@shack_pc:

enter password etc. to do the initial scp transfer

(on Shack PC)

$ cat id_rsa.pub » .ssh/authorized_keys2

then any further SSH or SCP sessions from the Rasperry Pi to the Shack PC should occur without any need for passwords.

The Pi is now set up for automatic SSH Remote Tunnel - as long as the script is run at boot time:

Crontab is used to fire off the tunnel and start SVXLink @reboot

@reboot sleep 60 && sudo -u gm4slv /home/gm4slv/tunnel.sh 2>&1
@reboot sleep 30 && sudo -u gm4slv /home/gm4slv/svx_ref.sh >/dev/null 2>&1

To check the Tunnel is up you look at netstat -ntl on the Shack PC:

gm4slv@laptop:~ $ sudo netstat -ntlp

SSH is listening on ports 4446, 20000 and 8080 which proves it's up and running.

Port 20000 (and 20001) is used by autossh to handle its “is the tunnel still up” packets.

From the Shack PC I can ssh localhost -p 4446 and reach the remove Pi, hostname svx

Antenna Changes

anonymous@undisclosed.example.com (Anonymous) — Tue, 07 Jul 2026 09:04:47 +0000

Antenna Changes

Now that I'm turning my attention back to QRP I decided that the antenna I've used for many years - an Inverted-L held up by (over the years) different supports, and currently a 10m SOTA-pole with the top few sections removed - tuned against a mess of radials and ground rods by a CG-3000 Auto-ATU - was due for a change.

The Auto-ATU needs “a few watts” to trigger a re-tune on a new frequency. Occasionally it'll work with 5W but not consistently, and certainly won't re-tune at anything lower than 5W. This means occasionally having to give it a carrier from a QRO radio to re-tune before switching to a QRP radio.

Not cool!

I'd considered a trapped inverted-L configuration, with traps for each band at the 1/4 wave points. But in a rare 60m SSB QSO with Stuart GM4WMM he told me he's using a multiband trapped End-Fed-Half-Wave. Fed via a 49:1 transformer, with the traps at the 1/2 wave points.

This removes the need for a good, low impedance ground connection and simplifies things. It also means “more wire” in the air for each band.

First Step - EFHW for 30m

I removed the Auto-ATU and put my nanoVNA on the current antenna/ground feed point to see what I've got now (a totally random length). The first resonance/low SWR is around 3.2MHz. That means a 1/4 wave at 3.2MHz or around 23m. I can perhaps squeeze a little more wire into the space but I'll accept that the new antenna overall length will be limited to “around 23m”.

Next I wound a 49:1 transformer on a FT50-43 toroid (the largest type-43 toroid I could find), and added the usual 100pF capacitor across the 50 ohm input.

Connecting this to the antenna - and also adding a connection to the existing ground system, mostly for consistency, and some static drain etc, I found a very good resonant return loss dip at around 6MHz. And another at 12MHz and another at 18MHz. As it stands I could use it as a 3 x 1/2 wave on 17m….

My main band is 30m. So the next step, to allow me to use 30m while I build the traps, was to shorten it to 1/2 wave resonance on 10.1MHz.

I now have a resonant “End Fed Half Wave” for 30m.

No need for an ATU (auto or manual).

Next step - trapped EFHW for 2 bands - 30m & 40m

I made a trap for 10.1MHz and added it to the end of the current antenna, then added wire to make a dual-band 30m / 40m antenna. That should cover my normal CW operations for a while.

I found that adding the trap and additional 40m section caused the the 30m resonance to move up about 200kHz, so I had to add about 12“ of wire to the first part of the antenna to bring it back down into band. Otherwise it was a simple to add the trap, add the extra wire, trim the far end to bring the 40m resonance into band.

I'm thinking of also trying to get 60m, but a 1/2 wave on 60m is around 30m and won't fit in the space - UNLESS the loading effect of the 30m and 40m traps, below their resonance, will add enough inductance shorten the required wire length sufficiently.

I need to re-make the 49:1 transformer with a larger toroid. Some calculations would imply that a 50-size core isn't suitable for 5W. So far I've not seen any evidence of problems (I'm assuming overheating would lead to a loss of correct transformer action, and loss of the impedance transformation - and hence high SWR. This hasn't been seen yet on CW at 5W or on WSPR at 1W, so perhaps it'll survive long enough for me to replace it with a 140-size toroid, once I buy a few….

Blogging Platforms

I've recently been playing with self-hosted blogging platforms.

It started with revisiting the Blog plugin for Dokuwiki and deciding that I wanted to use a purpose made blog platform instead.

This brought me back to re-visit Chyrp-Lite which I found easy to set up and to use.

Then I found Pure Blog which seemed even more light-weight and more akin to what I was looking for.

Then I found I was updating wiki-pages here in Dokuwiki and updating Blog pages in Pure Blog. Both are running on the same web-server.

And although I found it annoying to have to mentally flip between forms of Markdown, I got on with it, as I thought there was a benefit in separating wiki-like pages from blog-like posts.

Pure Blog drawbacks

Pure Blog is hard-coded to run in the root directory of a web-server. Not in a sub-directory. I tried it that way, and it doesn't work. This didn't pose too many problems at first.

My two instances of dokuwiki (home and work-related) ran in their own sub-directories, as does my old vintage 2001 website. So far so good.

Today I used the Pure Blog in-built update function to update the code to the latest version, and I found before pressing the GO button that the script wanted to clean out the webserver root directory of anything that wasn't part of Pure Blog.

That meant my sub-directories containing dokuwiki etc.

Well, that's not going to happen…

Instead it's “Bye Bye Pure Blog”

Back to Dokuwiki

I've re-instated the Dokuwiki Blog plugin and will go back to using it for the occasional blog-like post - something that doesn't fit in my existing structure for the wiki itself. I've copied across a few articles from the Pure Blog, fortunately there aren't many that I feel the need to drag across, and to correct the markdown & move the images etc.

I might continue to pull across a few more, as the mood takes me, but I'll basically just start afresh, from here.

Shack To Makerspace

Shack To Makerspace

I used to have a radio-shack in the house, with component drawers on the walls, a filing cabinet to keep tools, parts, hardware etc.

I built things and operated radios.

Move to the shed

Then in around 2013 I renovated the old garden shed and moved my shack out there. It was a pleasant few years having a space to do as I pleased, with just enough space to have a radio-bench and a work-bench.

Gradually the shed succumbed to the ravages of the Shetland weather and I decided it wasn't really worth continuing using it. And at the same time I gave up playing radio at all.

I had a few brief periods of in-the-house radio operation last year, but never really got deeply involved.

Move back to the house

Now, in 2026 I'm getting interested in radio again - in operating and in building. So I started setting up a shack. One rig was brought out of retirement. Then another.

I put shelves over the operating desk to hold some test gear etc. but I still had no real building/tinkering facilities. My component drawers, junk boxes, books and test gear were still in the shed.

Today I put a filing cabinet in the new shack. Moved books, test gear, some old projects and work in progress into the shack and then moved my wall-mounted component drawers from the shed to the new shack. I can now sit and tinker with circuits on my tiny operating desk. I can build projects. I can experiment. All from the relative comfort of my tiny shack.

I'm still finding places for everything, so it's a bit of a mess, but here's how it looks at the moment.

Laptop FreeBSD

←Computers

Laptop FreeBSD

I moved my Dell laptop from Devuan Linux to FreeBSD and here are some things I needed to do and some things I did for convenience….

Graphics

I found the basic install of the recommended drm-kmod package and i915kms driver wouldn't work - it crashed/hung during boot.

Removing this package and using the SCFB video driver worked, but didn't give (for example) DPMS control of the LCD screen.

I used SCFB temporarily be adding an xorg conf file 20-vesa.conf to /usr/local/etc/X11/xorg.conf.d/

Section "Device"
        Identifier "Card0"
        Driver "scfb"
EndSection

This was a reasonable workaround, but I found the solution to using correct Intel i915kms driver here : https://blog.hofstede.it/freebsd-150-on-the-thinkpad-t480-efficient-stable-and-8-hours-on-battery/

This is what worked:

Installed new packages

drm-latest-kmod

gpu-firmware-intel-kmod-kabylake

added to /etc/rc.conf

kld_list="i915kms"

added to /boot/loader.conf

# Graphics and power tuning
i915kms_load="YES"
drm.i915.enable_rc6=7
drm.i915.enable_fbc=1
drm.i915.lvds_downclock=1
drm.i915.enable_psr=1
compat.linuxkpi.i915_disable_power_well="0"

i915kms now loads and I have access to DPMS for turning off the LCD screen.

LCD Panel on/off

I made a few small shell scripts to assist in controlling the battery consumption by being able to alter LCD brightness, and turn the LCD off via DPMS and makde i3 shorcuts to them.

(later I made the same key actions for DWM when I moved back to using DWM)

now I can “$mod+Shift+o” to reduce brightness and “$mod+Shift+p” to increase it, and “$mod+Shift+i” to turn the LCD screen off completely.

I also added a devd rule to turn the LCD screen off when the lid is closed - this confused me initially, as it worked when testing it by adding the rule, restarting devd and testing, from within an X-Session…. but didn't work when devd was started during bootup…

This was due to the lack of DISPLAY if the script was triggered from “outside” the X session. Changing the script to set the DISPLAY variable was the solution.

/etc/devd/rules.d/lid.conf

notify 20 {
match "system" "ACPI";
match "subsystem" "Lid";
match "notify" "0x01";
action "/home/g4slv/bin/on";
};
notify 20 {
match "system" "ACPI";
match "subsystem" "Lid";
match "notify" "0x00";
action "/home/g4slv/bin/off";
};

The lid actions call one of these →

~/bin/on

#!/usr/local/bin/bash
 
su g4slv -c 'setenv DISPLAY :0.0 && /usr/local/bin/xset dpms force on'

~/bin/off

#!/usr/local/bin/bash
 
su g4slv -c 'setenv DISPLAY :0.0 && /usr/local/bin/xset dpms force off'

Other tweaks

Small scripts to automate swithing between Wifi and Ethernet

net_wlan.sh

#!/bin/sh
 
doas service netif stop em0 
doas service netif start wlan0
doas service dhclient restart wlan0

net_eth.sh

#!/bin/sh
 
doas service netif stop wlan0 
doas service netif start em0
doas service dhclient restart em0

Serial USB Adaptors

To get access to a USB serial device as normal user (as long as I'm in the wheel group) I added a rule in /etc/devd.conf

notify 100 {
        match "system"          "DEVFS";
        match "subsystem"       "CDEV";
        match "type"            "CREATE";
        match "cdev"            "ttyU[0-9]+";
        action "chmod ug+rw /dev/$cdev";
 
};

This makes the device R/W for the wheel group. Without this rule (the chmod part) the device is only R/W for root.

DM15L Non-linear Curve Fit

anonymous@undisclosed.example.com (Anonymous) — Mon, 06 Apr 2026 12:40:53 +0000

←Hints & Tips

DM15L Non-linear Curve Fit

Using DM15L/HP15C built-in L.R function to fit non-linear curves

Background

The idea is that the 3 different non-linear function forms can be expressed as linear expression y = m.x + c if we manipulate the x or y values before adding them to the statistics accumulator.

The different curves require different treatment of the data to linearize, and the resulting coefficients may require treatment too.

Tl;dr

Method for Exponential

y = b.e^ax

Ln(y) = a.x + Ln(b)

Enter Accumulation data	`y_i gLn x_i ∑+`
Calculate coefficients	`fL.R.e^x`
Estimate ŷ & r for a new `x`	`x fŷ.r e^x`

Method for Logarithmic

y=a.ln(x)+b

y = a.Ln(x) + b

Enter Accumulation data	`y_i Enter x_i gLn∑+`
Calculate coefficients	`fL.R.`
Estimate ŷ & r for a new `x`	`xgLn fŷ.r`

Method for Power

y=b.x^a

Ln(y) = a.Ln(x) + Ln(b)

Enter Accumulation data	`y_i gLn x_i gLn∑+`
Calculate coefficients	`fL.R.e^x`
Estimate ŷ & r for a new `x`	`x gLnfŷ.re^x`

Exponential

y = b.e^ax

This can be expressed as Ln(y) = Ln(b) + a.x

Ln(y) = a.x + ln(b)

compare with a linear expression y = m.x + c

Using Ln(y) and x as data points and running the L.R. function will give coefficients equal to a and ln(b)

You can obtain the actual value of b finding its antilog with e^x.

Once the L.R. has run you can find estimates of ŷ by running the fŷ.r to get the estimate of Ln(y) and then finding its antilog with e^x

Mechanism

To enter the data points you convert the y data to its Ln first, then accumulate as normal

y_i gLn x_i ∑+

Once all the data has been entered you get the Linear Regression coefficients a & b fL.R. and e^x to correct the b LR coefficient.

Example Data

y	2.8	3.6	5.8	8.0
x	0.8	1.1	1.7	2.1

fClear ∑

2.8 gLn 0.8 ∑+

3.6 gLn 1.1 ∑+

5.8 gLn 1.7 ∑+

8.0 gLn 2.1 ∑+

All data is in the accumulator, now do the Linear Regression fL.R.

This gives a and Ln b coefficients

Y: 0.805 = a

X: 0.3897 = ln b

so we need to find b so e^x

Y: 0.805 = a

X: 1.476 = b

Equation estimation is therefore y = 1.476 e ^0.805x

I made the data table by using the equation y = 1.5 e ^0.8x and then used approx. y values for the data table…. so the estimate looks pretty good

To do an estimation of y when x = 0.9

0.9 fŷ.r e^x

Y: 0.999962 = r correlation coefficient

X: 3.047425 = ŷ estimation

Method for Exponential

Enter Accumulation data	`y_i gLn x_i ∑+`
Calculate coefficients	`fL.R.e^x`
Estimate ŷ & r for a new `x`	`x fŷ.r e^x`

Logarithmic

y = a.ln(x) + b

Compare to a linear expression y = m.x + c shows the logarithmic curve is linear if we use Ln(x) as we accumulate data points.

The L.R. will provide the actual a and b coefficients.

To estimate ŷ first find the Ln of x then use the fŷ.r

Mechanism

y_i Enter x_i gLn∑+

Calculate LR Coefficients

fL.R.

Calculate estimated ŷ by finding the Ln of your x value first and then using fŷ.r

xgLnfŷ.r

Example Data

y	1.5	1.7	1.8	2.1
x	0.8	1.7	2.6	4.9

fClear ∑

1.5 Enter 0.8 gLn∑+

1.7 Enter 1.7 gLn∑+

1.8 Enter 2.6 gLn∑+

2.1 Enter 4.9 gLn∑+

Linear Regression Coefficients : fL.R.

Y: 0.324 = a

X: 1.544 = b

Equation y = 0.324 . Ln(x) + 1.544

Estimate ŷ for X = 3

3 gLn fŷ.r

Y: 0.985 = r, correlation coefficient

X: 1.900 = ŷ, estimation

Method for Logarithmic

Enter Accumulation data	`y_i Enter x_i gLn∑+`
Calculate coefficients	`fL.R.`
Estimate ŷ & r for a new `x`	`xgLn fŷ.r`

Power

y = b.x^a

This can be rearranged as Ln(y) = Ln(b) + a.Ln(x) or Ln(y) = a.Ln(x) + Ln(b)

Compare to a linear expression y = m.x + c

Our expression will be a straight line if we accumulate Ln(y) and Ln(x)

The coefficients given by the L.R. function will be a and Ln(b) - so to get the real b coefficient we find its antilog e^x

We get the estimate for ŷ we first find the Ln of our chosen x and then use the ŷ.r to get Ln(ŷ) and then e^x to get ŷ

Mechanism

Accumulate using

y_i gLn x_i gLn∑+

Calculate LR Coefficients

fL.R.e^x

Calculate estimated ŷ

xgLnfŷ.re^x

Example Data

y	1.3	2.2	3.3	4.4
x	0.6	1.3	2.4	3.6

fClear ∑

1.3 gLn 0.6 gLn∑+

2.2 gLn 1.3 gLn∑+

3.3 gLn 2.4 gLn∑+

4.4 gLn 3.6 gLn∑+

Linear Regression Coefficients : fL.R.e^x

Y: 0.678 = a

X: 1.837 = b

Equation : y = 1.837x^0.678

Estimate ŷ for X = 3

3 gLnfŷ.re^x

Y: 1.000 = r, correlation coefficient

X: 3.869 = ŷ, estimation

Method for Power

Enter Accumulation data	`y_i gLn x_i gLn∑+`
Calculate coefficients	`fL.R.e^x`
Estimate ŷ & r for a new `x`	`x gLnfŷ.re^x`

DM15L/41X/41L "Multi-Variable" Solve

Using multi-variable equations in SOLVE

Source

https://www.hpmuseum.org/cgi-sys/cgiwrap/hpmuseum/articles.cgi?read=556

In order to conveniently employ SOLVE or INTEG on the HP-34C/15C/41C for multiple-input, single-output (MISO) user-defined functions, the user's program should emulate the way SOLVE and INTEG manage input variables on the three Pioneer-series models and the HP-33s.

Assume that a MISO function is to be programmed as an RPN routine on a HP-34C, HP-15C, or HP-41C/CV/CX. A user may wish to use SOLVE or INTEG successively for any selected “focus” variable with all others held constant, and without having to edit the RPN routine. Here is a simple procedure for this purpose:

Choose a numbered storage register for each variable in the function. On the 41C/CV/CX, choose another numbered register as the indirect storage register. (Do not use a stack register, as it will be overwritten by SOLVE or INTEG.) In PROGRAM mode:

Program the function as an RPN routine that not only meets the basic requirements, but also retrieves each variable from its chosen storage register when it is used. (On the 41C/CV/CX, the label beginning the routine must be an external label.) The second instruction of the routine (immediately after LBL) should store the stack x-register value to the indirectly-referenced register. This instruction is “STO (i)” on the HP-34C and HP-15C; it is “STO IND nn” on the HP-41C/CV/CX. In RUN mode:

Store the desired constant values of the fixed-value variables to their storage registers. Store the register number containing the floating variable to the indirect storage register. Invoke SOLVE or INTEG in the usual manner. This procedure utilizes indirect storage to make the RPN program more flexible. SOLVE and INTEG feed the each value of the floating variable as input to the user program, which immediately stores the value indirectly to its user-chosen register. Each variable in the function is then recalled for use in calculations, so the user program need not be structured to receive any particular variable from the stack.
EXAMPLE:

f(x, y, z) = 2*x - ln y + 1/z

x in R1; y in R2; z in R3
indirect in R00 (HP-41 only)

DM41X Ladybug Module

←Hints & Tips

DM41X Ladybug Module

Another HP16 emulation

Ladybug Key Overlay

Details

Ladybug is a more user-friendly, if less versatile, “HP16C programmer's calculator” module than the fully-featured HP16 module by Angel Martin. Both have their uses, but for a simple calculator for bit-banging while writing 6502 assembly code Ladybug does everything, with a less convoluted User Interface.

Although I also have a DM16L, the Swiss Micros modern clone of the original HP16C, I am finding that having Ladybug on the DM41X allows me to quickly switch between “normal” floating point calculations and integer “programming” calculations, and have access to the best of both worlds.

The DM16L/HP16C has very limited (basically unusable) floating point support.

The Ladybug module is more intuitive and usable than the Angel Martin HP16 emulator module and having Ladybug for INTEGER and the rest of the DM41X/HP41CX functionality for other tasks makes the DM41X my go-to calculator. The DM16L is fantastic as a single-minded programmer's calculator, and is used extensively when I'm engrossed in writing assembly code, but the DM41X is much more versatile and is carried with me at all times when I'm away from the workbench.

Launching

modules needed:
- Ladybug
- Boost
- OS/4

To switch to “Ladybug Integer” mode : XEQALPHAINTEGERALPHA

To leave (and return to normal mode) : XEQALPHAEXITAPPALPHA

Using the DM41X CST menu simplifies this, set 2 Custom menu entries for INTEGER and EXITAPP

Nice features

A “CMP” function akin to 6502 - sets flags in the same way but doesn't change the register(s)
Status Flags : C, Z, N and V equivalent to 6502 flags and set in the same way after various operations.
- Flag 0 = Zero Z
- Flag 1 = Sign N
- Flag 3 = Carry C
- Flag 4 = Overflow V
2's-complement mode is set with Flag 2
Leading Zeros display is set with Flag 5

Word Size is set with Shift+R/S
Windowing is selected with .
Bits can be set Shift+4, reset Shift+5 and tested Shift+6

Boolean Operations on values in X and Y registers
- AND Shift+1
- OR Shift+2
- XOR Shift+3

NOT Shift+CHS (invert each bit, on the value in the X register)

Shift and Rotate functions are conveniently accessible - see Overlay picture above - without delving into menus or launchers

DM41X Hints & Tips

Module Switching

Using the Ladybug module for Integer/Base calculations means it's impossible to also have the 41Z complex number module or the HP16C simulator module and the necessary library “plugged in” at the same time. There is a clash between Library 4 needed for 41z (and also needed for 16C) and OS/4 which is needed for Ladybug.

I've used the DM41X “module save/load” function to have different module-plugged states:

41z.m41 : with 41Z 2×2 Deluxe and Library 4 modules active
16c.m41 : with HP16 C Simulator and Library 4 modules active
lady.m41 : with Boost, OS/4 and Ladybug modules active
adv.m41 : with Advantage Pac module active

These are accessed via setup → 2. Module → 4. Load Modules → 1. Load AM list

Choosing the required *.m41 file will automatically unplug/plug whichever modules were active when the config. was saved.

This makes it easier to remember which supporting library/module are needed to use each particular module's functions.

It's possible to also save the flash state - which modules have been pre-loaded into the DM41X's Flash Memory making them available to be plugged in using different options at the setup 2. Module choices…. you'll work it out.

Advantage Pac : Flag 21

I found that using some of the Advantage Pac programs (e.g. MATRX or CFIT) would lead to AVIEW instructions in programs run subsequently to cause a HALT - requiring use of the R/S key.

I was told via a question on the Swiss Micros Forum that this was likely to be due to the Advantage Pac setting FLAG 21 (printer active) to help in its own presentation of information on the display.

FLAG 21 SET while FLAG 55 is CLEAR (since there's no Printer Module active) causes AVIEW instructions to halt awaiting user intervention (R/S key)

To restore things to normal : either CLEAR Flag 21 via CF or simply turn the calculator off and on again.

See APPENDIX D in the HP41CX User Manual Volume 2 for a better explanation of the use of Flag 21 to control AVIEW behaviour.

Extended Memory

Copy a program to Extended Memory:

Put Prog's name in Alpha register
XEQ storep
The prog remains in main memory but can be deleted (CLP) if memory needed
To restore to main memory put name in Alpha and then XEQ GETSUB

DDAYS

To find the number of days between two dates

enter 1^st date into Y-stack as dd.mmyyyy
key in 2^nd date into X-stack as dd.mmyyyy
XEQ ALPHA D D A Y S ALPHA
result is the difference in days.
DDAYS can be added to the CST program chooser to make it easier if multiple calculations are required

Example

Days between 27/2/66 and 31/5/22

27.021966 ENTER 31.052022 XEQ ALPHA D D A Y S ALPHA

Result = 20,547

Check :

365 ÷

Result 56.293

I'm 56 and a bit… sounds right…

XYZALM

Various Alarm functions

Put any message for the Alarm into the ALHPA register

Load the stack registers with:

Z : Repeat Interval HHHH.MMSSs or 0
Y : Date DD.MMYYYY or 0
X : Time HH.MMSSs

Execute XYZALM to set the alarm

When alarm goes off it is acknowledged by pressing any key except STO.

Acknowledging a non-repeating (i.e. Z was 0) alarm cancels it.
Acknowledging a repeating alarm cancels it and re-arms it, adding the Repeat Interval to create the new alarm time.
Pressing STO cancels the alarm but makes it a PAST DUE alarm.

Example

Set alarm for 22:20, today, not repeating, called Supper

ALPHA S U P PER ALPHA
0 ENTER (for Z = repeat interval)
0 ENTER (for Y = Date = Today)
22.20 XEQ ALPHA X Y Z A L M ALPHA

At 22:20 the alarm is activated. ALPHA shows SUPPER.

Alarm is cancelled by pressing any key but STO

Pressing STO creates a PAST DUE alarm which means it gets re-triggered if the calculator is turned off. It can be cancelled and deleted by pressing any key (except STO) and then the calculator will turn off. Pressing STO will create a new Past Due alarm, and allow the calculator to turn off. On turn on the Past Due alarm will still exist and turning off will trigger it again.

A Past Due alarm is useful to remind you that something happened previously and turning the calculator off is a memory-jogger.

CATALOGUE 5 R/S and ⇑ ⇓ steps through all alarms.

To clear an alarm from the Catalogue: SHIFT C ( where C is √ on top row )

Notes

Bought on eBay as a first, relatively cheap, vintage HP Voyager model. Some of the keys are a little vague feeling, although always registering positively and never missing a key-press (unlike the Swiss Micro DM15L which occasionally misses a key-press if it's not performed with enough pressure).

I like the old feel, and although it's noticeably slower than more modern calculators, it has plenty of useful features and functions to be carried and used when the higher power or features of the DM42, DM41X or DM15L are not needed.

DM32 Progs

Description

Return Loss & SWR from Complex Impedance

Input Rs and Xs to calculate |z|, |ρ|, VSWR and R.Loss

Complex numbers in DM32

The DM32/HP31Sii handles complex numbers by treating stack-X as Real, stack-Y and Imaginary for one complex number, and stack-Z as Real and stack-T as Imaginary for a second complex number.

This means the normal 4 level stack can hold 2 complex numbers. This is similar to the HP41 Advantage Pack's method.

To store a complex number in a register actually requires two to be used - one for Real part and one for Imaginary part. This is similar to the HP15C/DM15L.

Once the real and imaginary values are on the stack various “Complex” functions are accessed by SHIFTCMPLXFunction for example to add

Z₁ = (10 + j20)

and

Z₂ = (30 - j25)

gives

Z₃ = Z₁ + Z₂ = ( 10 + j20 ) + ( 30 - j25 )

20 ENTER 10 ENTER
25 CHS ENTER 30

The stack will show

Then carry out the addition

SHIFT CMPLX +

The display will show

X has the real part of Z₃ (40) and Y has the imaginary part of Z₃ (-5)

Z₃ = ( 40 - j5 )

The program

LBL Z
INPUT R
INPUT X
X<>Y       ; swap so Real is R and Imag is X
0
ENTER
50         ; enter Zo as 50 + j 0 
CMPLX +    ; complex addition Z + Zo
STO A      ; store intermediate value Re (Z + Zo)
R↓        
STO B      ; store intermediate value Im (Z + Zo)
R↓         ; X and Y stack now holds input Z real & imag again   
0
ENTER
50         ; enter Zo as 50 + j 0 (again)
CMPLX -    ; complex subtraction Z - Zo
RCL B      ; Im (Z + Zo)  
RCL A      ; Re (Z + Zo)
CMPLX ÷    ; complex divide (STACK z,t holds (Z - Zo) stack x,y holds (Z + Zo) (from reg. A & B) to calculate complex reflection coeff. ρ
STO E      ; save Re ρ
R↓
STO F      ; save Im ρ
RCL E
y,x -> θ, r ; convert complex rectangular ρ to mag/angle - X holds the magnitude |ρ| ( Y holds the angle, but we don't care)
STO P       ; save |ρ|
1
RCL+ P
1
RCL- P
÷
STO S       ; store VSWR ( 1 + |ρ| ) / ( 1 - |ρ| ) 
RCL P       
LOG

X
STO Y       ; store Return Loss = 20 LOG |ρ|
RCL X

STO Z       ; store magnitude of impedance |z|
RCL P       ; |ρ|
RCL S       ; VSWR
RCL Y       ; Return Loss
RTN

Example

Z = 65.2 + j 17.7
R = 65.2
X = 17.7

Results on stack:

|Z| = 67.6 ohms
|ρ| = 0.2
SWR = 1.5:1
Return Loss = 13.9dB

Dokuwiki Mirror

I'm running a SANDBOX installation of dokuwiki on the small headless server in have in the shack.

This is to allow me to mess around with templates and layouts and things without impacting the real wiki.

To give it some data - a full mirror of the existing real wiki - I've used rsync

cd /var/www/html/
sudo rsync -av --delete gm4slv@gm4slv.org.uk:/var/www/html/dokuwiki/ ./dokuwiki/

This copies the production wiki into the web server root on the little sandbox machine.

UPDATE — John Pumford-Green 27/04/23 05:53

Added –delete to the command, to remove pages in the Mirror copy that have been deleted from the VPS (production) server, to keep them properly in step.

I can then play around to my heart's content.

The same mechanism would work to retrieve/install the whole wiki from a backup

I've put it in a shell script:

#!/bin/bash
 
WEBDIR=/var/www/html/dokuwiki/
 
SERVERDIR=/var/www/html/dokuwiki/
 
SERVER=gm4slv.org.uk
 
 
sudo  rsync -e "ssh -l gm4slv -i /home/gm4slv/.ssh/id_rsa"  -av $SERVER:$SERVERDIR $WEBDIR

This means I can automate the mirroring with crontab of I wanted to, but it would mean the sandbox will lose any local modifications I've done. Perhaps it's best to keep the option to revert to production version as something I do from time to time, rather then automatically.

Code & Command Snippets

Windows WiFi Disconnect

Windows will disconnect a WIFI connection when it discovers there's no WAN internet - presumably Windows thinks ALL networks are connected to the Internet and this prevents using WIFI for an isolated LAN, and also throws you off the WLAN whenever the ADSL connection fails, even when you're busy using only internal LAN sessions.

THIS IS WRONG BEHAVIOUR.

I found a solution, and typically it's a REGEDIT task:

From : https://superuser.com/questions/1650052/how-to-keep-windows-10-connected-to-wifi-without-internet

Add a Registry DWORD “NoActiveProbe” value “1” at Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\NetworkConnectivityStatusIndicator

Job Done. You stay on your LAN even when the interwebs is down.

Chrome redirects

To remove a “permanent redirect” - e.g. from an http to an https URL - I found the answer here:

https://www.neilwithdata.com/chrome-redirect-forget

Open the Chrome Developer Tools (F12)
Go to the Network tab and make sure Disable cache is ticked
Reload (or navigate to) the page you no longer want to be redirected while keeping the dev tools open.

Vim Pasting

I recently had problems pasting text into Vim by the traditional RIGHT click method. Vim would enter Insert(VISUAL) mode instead.

One solution when using Putty is to use its own mechanism :

SHIFT+INS

I prefer to use RIGHT click, as it's more natural so I found the solution is to add

set mouse-=a

to ~/.vimrc

This solves the problem, and I don't need to use nano when editing text files on my remote server via SSH using Putty.

R Pi Image files

Various tips and tricks for working with Raspberry Pi Disk Images

Taking an image

remove SD card from Pi
insert into PC
unmount the image partitions if they get auto-mounted

take the image using dd

sudo dd if=/dev/mmblahblah of=name_of_image.img bs=4M

wait….. and wait….
this can now be either
1. saved as it is (possibly a big file)
2. compressed with gzip
```
gzip name_of_image.img
```
an alternative is to make sure the image is as small as it needs to be, appropriate to the space actually needed by the installed OS.

Using ''losetup'' to work with the image file

The image can be used as a loop device and then mounted as a normal disk to allow access to the files etc.

To access the image as a loop device you let losetup find the partitions automatically and convert them to to loop partitions loop0p1 (the /boot partition) and loop0p2 the root partition. You can then mount whichever one you need.

gm4slv@laptop:~/piimg $ sudo losetup -Pf igate.img
gm4slv@laptop:~/piimg $ lsblk
NAME      MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT
loop0       7:0    0   4.3G  0 loop
├─loop0p1 259:0    0   256M  0 part
└─loop0p2 259:1    0     4G  0 part
sda         8:0    0 298.1G  0 disk
├─sda1      8:1    0 235.1G  0 part /
├─sda2      8:2    0     1K  0 part
├─sda3      8:3    0  50.9G  0 part
└─sda5      8:5    0  12.1G  0 part [SWAP]
sr0        11:0    1  1024M  0 rom
gm4slv@laptop:~/piimg $ sudo mount /dev/loop0p2 /mnt
gm4slv@laptop:~/piimg $ cd /mnt
gm4slv@laptop:/mnt $ ls
bin  boot  dev  etc  home  lib  lost+found  media  mnt  opt  proc  root  run  sbin  share  srv  sys  tmp  usr  var
gm4slv@laptop:/mnt $ cd etc/
gm4slv@laptop:/mnt/etc $ cat hostname
igate
gm4slv@laptop:/mnt/etc $

This allows you to change files (one example is to set a fixed IP address in /etc/dhcpcd.conf) as required.

Shrinking the image

If the OS had been expanded after install to fill the whole SD Card space there is now a lot of pointless wasted space in the image that

takes up disk space to store
makes copying to a new SD card slow
makes it impossible to copy to a smaller card

The image can be shrunk to a more appropriate size.

The gist of it is here

unmount the loop device:
```
sudo umount /mnt
```
use gparted (need to be at a machine with a graphical session) to shrink the partition to a more suitable size, leaving some room for safety
dispose of the loop device
```
sudo losetup -d loop0
```
The *.img file is still the same size, but the partitions within the file are smaller, the rest of the space needs to be stripped from the *.img file with truncate
Use fdisk to inspect the image file to see where the partitions start and end

gm4slv@laptop:~/piimg $ sudo fdisk -l igate.img
Disk igate.img: 4.25 GiB, 4563402752 bytes, 8912896 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: dos
Disk identifier: 0x38ea48c4
 
Device     Boot  Start     End Sectors  Size Id Type
igate.img1        8192  532479  524288  256M  c W95 FAT32 (LBA)
igate.img2      532480 8912895 8380416    4G 83 Linux

The second partition ends at block 8912895 so you shrink the filesystem to this point (plus one). This requires the calculation of the actual number of bytes, based on the block size of 512 bytes.
Either calculate it yourself, or put the calculation in the command:
- ```
 sudo truncate --size=$[(8912895+1)*512] name_of_image.img
```

Voila, a smaller image on file which uses just enough space for the already known to be working OS

Summer 2022

We finally admitted defeat with the plan to rebuild/refurbish our old Thorn Club Tours :

It was a romantic idea to restore them to their former glory, but realistically it would have been unjustifiably expensive and time consuming… we just wanted to ride bikes again after several years away from them.

So we decided to invest in 2 new modern hybrid bikes instead.

Two new Trek FX 2 Disc (Equipped) will replace the old Club Tours.

Mastodon & Twitter

Mastodon & Twitter

— John Pumford-Green 20/12/22 07:39

I recently tried Mastodon - the distributed, not-powered-by-advertising, not-run-by-megalomaniac-billionaires social media platform.

This was after years of “not-using-Twitter”. I didn't use Twitter for a variety of reasons. One was “what's the point of it?” and another was “I don't like AI and Algorithms deciding what I should see” and another was “I ABSOLUTELY HATE ADVERTISING”.

I'd looked at Mastodon a few times over the last year or so, but thought “what's the point of it?” and “everyone else is on Twitter anyway”.

Then Elon Musk took over Twitter and there seemed to be a mass exodus of people, and Mastodon was where they were going.

So I set up a Mastodon account and started to explore.

Initially it seemed to make sense - I had an account on an “instance” centred around the radio hobby, and most of the postings were interesting (or at least “on topic”) and it looked like it was possible to get involved, make “friends” and share experiences, and even post/read/enjoy the odd off-topic item.

I couldn't shake off the annoyance I felt that many of the posts were references to things still going on “over in the other place”, “on the Bird Site” etc. Lots of Twitter-in-jokes and references, that made no sense to people who had no interest or previous connection with Twitter, and were probably also annoying to people who had “escaped” Twitter and were enjoying the new atmosphere of Mastodon.

Carrying over old Twitter baggage started to dominate (as I saw things) as more and more “refugees” made the jump.

Endless “have I done the right thing?” or “I'm here now, what do I do?”, or “This doesn't work like Twitter, I don't like X, Y or Z”.

… then the floods of “memes” referencing ongoing Twitter happenings…

In my mind if you leave Twitter and join Mastodon you don't need to keep dragging over Twitter-related posts, jokes, comments, memes.

I started trying to filter out content I didn't want to wade through, stuff that made no sense to me (as a non-Twitter user), then I started un-following people that persisted in filling up the timeline(s) with such stuff.

Then I thought “What's the point of this?”

I'd managed perfectly well without Twitter all these years.

I was now spending more time trying to “clean up” my Mastodon timeline & home feed than I was happy with.

So I decide “No. It's not for me”

and Deleted my Mastodon.radio account (as well as the account I'd set up but not yet used on Mastodonapp.uk)

Enough was enough.

I'm just not a “social media microblogging” kind of person, I suppose.

Prepping

— John Pumford-Green 21/12/22 23:07

We had a “weather event” on Monday December 12th 2022 - a short, sharp and vicious snow storm. Some snow fell earlier in the day, but until lunchtime it wasn't really anything to get excited about….

Then it turned nasty, and somewhat surreal.

The Shetland Power Outage of December 2022

The snow became heavier and had a peculiar “sticky wetness” about it, causing it to cover roads quickly. More significantly it started to cling to overhead power lines, building rapidly and freezing on the lines causing them to begin to fail as the strong wind began to blow the thickened and heavily weighted lines to break under the strain.

I'll ignore the specific sequence of events of my day, as I'm more interested here in the longer term consequences of the snow storm rather then the “excitement” of the day's drama.

We eventually got home after a 4 hour journey in very poor weather, with bad roads (and not a few poor drivers, unused or unable to drive in snow) to contend with, at approx 8pm to find the power at home had failed. This is not unusual, and initially the electricity company (SSEN) were estimating 23:00 for restoration. No problem, we have wood-burning stoves for heating, in two rooms, and a gas (propane) cooker for heating water and for cooking food.

One evening without power is not unusual, and nothing to worry about.

We had our Petzl headtorches on, we lit the woodstoves and we made a meal.

As the evening went on, the full severity of the power failures began to be known, and the repair estimate moved to “22:00 tomorrow”…. It moved further and further away with each successive update.

This was the start of a 6 day power outage, in sub-zero weather conditions, with snow and ice and occasional gale force winds.

The 3 mile section of single track road connecting us to the main road network, and to shops for supplies, was almost impassable by the next morning. I certainly wasn't willing to try my luck, in a 2WD van, for the next 3 days, so we were effectively trapped at home with no power, and the estimated restore time kept being extended as more and more was known of the severity of the damage to the overhead power distribution system. Many, many lines and poles were down. Crews of engineers, and materials, specialized vehicles, helicopters were mobilized from the mainland and began to arrive in the following days.

Short sharp weather event, long power failure

The damage occurred on Monday afternoon, after approx 4 hours of heavy snowfall.

Our power was reconnected at 00:20 on Sunday morning, almost 6 days later.

In that time we had managed to get new food and other supplies on Thursday and Friday, as the road became passable, and the power remained off.

We maintained a continuous online internet and mobile phone connection
we had lighting from headtorches
heat from multi-fuel (Morso Squirrel) stoves
cooking from propane gas cooker.
The water supply remained on throughout.
Food supplies were initially limited for the first few days

“Monday is shopping day” and we usually run-down the stores during the week and replenish the larder on a Monday. The “event” on Monday prevented the usual weekly shop.

We don't keep any emergency supplies of food.

Things that were helpful

a supply of pre-charged 12V Sealed Lead Acid batteries. This allows for re-charging of USB devices (phones, headtorches, USB Battery-power-banks etc) when paired with a 12V powered USB hub, or using a quickly home-made 12V → 5V regulator (7805).
a battery powered 4G MiFi router with an appropriate (EE) SIM card (PAYG, with plenty of Data Credit). This allows continuous connection to internet - important to keep in touch with friends, and to keep abreast of news and announcements about the progress of power repairs.
Petzel headtorches always close at hand. We each have Petzl “Actik Core” headtorches with USB rechargable battery packs. The batteries can be replaced with 3 x AAA batteries if necessary.
a supply of fuel for the Morso Squirrel stoves. This was a recent delivery of £300 worth of softwood logs. At other times of the year we may not have a stock of firewood.
a source of cooking and water heating that doesn't rely on electricity. Propane (Calor) gas powered kitchen cooker, common in rural areas.

Things that could have been better, with pre-planning

Food - have a dedicated supply of long-shelf-life food items, that can be relied on even if the normal food supply is at a low ebb. Keeping a slightly larger “normal” larder, by allowing a reserve to build up week by week, without going mad would also be of assistance, especially for items that wouldn't be suitable for the “emergency long-shelf-life” food cache.
Hygiene and health - have a supply of toilet paper, wet wipes, pain killers, simple first aid items, batteries, candles, matches, lighters. Keep these in one box where they will only be used “in an emergency”.
Water. While this event did not involve a loss of mains water for us, it did affect water supplies elsewhere. In any future event it is not unrealistic to imagine a loss of supply. It would be worthwhile having a stock of water, for drinking, cooking, hygiene etc.
A better form of 12V power - larger capacity batteries, that were known to be fully charged. A 100Ah Leisure battery and a number of 24Ah Sealed Lead acid battery would be longer lasting and provide more confidence, than a random group of “condition unknown” smaller (3Ah?) SLABs.
A pre-prepared source of fuel for the Morso stoves. Wood is useful, but in general is not likely to be kept in sufficent quantity. A better option are smokeless Ovoids. Once the stoves are lit with Ovoids they can be kept burning continuously, 24/7 for days or weeks at a time, and only require 2 daily top ups of new fuel. One bag of ovoids, with care, can fuel 2 stoves for 2 days.
Lighting - a supply of tea-lights and candles would have allowed background room-lighting to supplement the head torches and make the long dark winter evenings more enjoyable. Perhaps a system of 12V powered LED lighting would be even better.
Batteries - have a supply of AA, AAA and CR123 batteries for torches, radios etc
Battery powered AM/FM radio for entertainment without relying on internet/streaming.
Power for ADSL router to allow internet connection without relying on a 4G mobile phone signal. It is possible the ADSL connection may not be available, depending on the state of the power at the local exchange. Having a choice between 4G and ADSL would allow options, though.

Thoughts for the future

Having experienced a 6-day power outage following a single afternoon of heavy snow, it's now easy to imagine a much longer storm, causing much more widespread damage, and leading to a much longer period without power, and without access to the “outside world”.

I am tending to the opinion that it is worthwhile planning for a period of 14 days. Being self-sufficient, at home, with no external assistance, for 2 weeks might never be needed, but the security and confidence of building up this level of preparedness, is liberating. It also means that we won't be a burden on any support services, allowing them to concentrate on the more vulnerable and less well prepared. We can also provide assistance to others if we have a surplus of stores, supplies, tools, batteries, etc.

Becoming a Prepper

I've often read online prepper websites and watched Prepper You Tube videos. Many of them have a few sensible points, but often are aimed at a level of “disaster survival” that seemed of little relevance.

Now, after, a simple snow storm (admittedly of a peculiar type of very wet, very heavy , icy snow) led to being isolated at home for 6 days with no power, it is EASY to imagine a much worse, or longer lasting, event requiring off-grid living, at home, for a longer time period.

I see the benefit of making some simple pre-preperations. Not to survive “the Zombie Apocalypse” or “TEOTWAWKI”, but just a failure of our utility supplies - Electricity, Water or the blockage of transport routes by snow, ice, landslide etc.

If you are going to lay in stores of materials, consumables, food and water, then it's probably worth trying to aim for 14 days of self-sufficiency. Even if not for “natural disaster” - perhaps sudden unforseen job loss, lack of accessible cash/online payment - having enough at home to live for 2 weeks relieves some of the stress.

COVID, with the orders to stay at home, for shops to either be told to close, or for panic buying to rapidly empty the shelves has also shown that unusual situations can occur without warning, and the ability to sit-tight for 2 weeks allows time for a degree of normality to be restored, and shops to be restocked.

More examples come to mind as I think of scenarios to prepare for. Until recently they would appear fanciful, but now, post COVID with climate change starting to impact even the temperate UK weather systems, it's perhaps not hysterical to start planning and prepping for future events.

I'll start adding more pages to the WiKi as I explore Prepping as a project, with the aim of achieving a 14 day autonomy over the course of the next few months.

Watchwinder

Home Brew Winder

I built a simple watch-winder to keep automatic watches fully wound when not being worn. Mainly as a small project to play with a pyBoard and a servo motor.

A short piece of microPython makes the servo turn, first one direction, then then other, then a pause, at a speed that makes sure a watch is fully wound overnight. The speed depends on the required number of turns to achieve full-wind, which depends on the watch movement, and whether the movement winds in one or other, or both, rotational directions.

The watch is placed in a plastic box attached to the servo motor and the motor is simple clamped in a panavise, with the axis of the servo at about 45°

CRT SS9900

CRT SS9900

Multi-Mode 10m/11m/12m

Background

I wanted a mobile 10m radio for use on 10m FM, and occasionally SSB, to try and re-capture the fun I had in the early days of being a ham (1983). Looking around I found a lot of choice of radios covering 12m and 10m amateur bands, and (of course) all the space in between containing the 11m/CB bands.

I bought a CRT9900 which seemed to offer the best versatility - it's more like a ham radio than a channelized CB.

It's hardly been used - I don't think I've ever had a QSO with it yet - so I now intend to make a concerted effort to get some use from it, and even looking at 11m when 10m is moribund.

Propagation conditions should be improving as Solar Cycle 25 peaks, and (writing this in early May 2023) the summer Sporadic-E season should also bring some inter-Europe propagation too.

p.s. I even have a CB callsign from the Charlie Tango group : “108 CT 2182” (108 = Scotland and I asked for 2182 as a nod to SSB marine radio)

SSB TX EQ

I'm not naturally a 'phone operator and avoid playing with audio settings as much as possible. I prefer simple “communications quality” audio when I use SSB. As the FT-891 is intended to be my “phone mode radio” and I've done some initial adjustments to try and achieve a clean, basic communications-quality setup.

From what I can work out, the “bandwidth” settings of the EQ refer to Q - the smaller the number the lower the Q and the wider the affected bandwidth. I'm aiming for gentle shaping of the voice band to cut the low-end boomy bass and lift the high end “articulation” so I've set a low-Q on each pole of the EQ filter. I've set both the non-Compression and the Compression EQ settings to the same values - I want the audio to sound the same with and without the processor. The Mic's rear “tone” switch can be used to give a slight increase in low frequencies by switching → 1 if I ever feel the need.

Here are the settings I've got on the FT-891

GPO Brass Key

GPO Brass Key

An old brass GPO key

A bog-standard brass GPO key, I think. I can't remember where it came from, I picked it up somewhere along my radio journey.

It's quite a nice little key, but I find it a bit “hard” - there's no springiness to the contact closure whatsoever. My HK-708 has a little give, mainly I think due to the spring-loaded ball bearings holding the trunnion rods - but this GPO key is very “rigid”. It sends nicely, once I get used to the feel. I've got it adjusted to my liking, and can happily send at 20+ wpm, but I have to be in the right mood to enjoy using it. If I had to use only one key, and it was this one, I'm sure I'd be happy, but while I have a choice I tend to pick something else.

Seeing how different keys feel does make me wonder about obtaining more, just for the interesting variety of sending feel that's there to be sampled!

Hi-Mound HK-708 Key

My original key from 1982

My HK-708 in all its glory

I got this key while I was still at school, in around 1982, to use for learning to send CW. It was all I could afford at the time, and must have been quite cheap. I've had it, and used it, for over 40 years now, and it's still my main straight key for most QSOs.

Inscribed with my original callsign in about 1983

(and if the recently announced OFCOM licence review goes through unchanged I'll be allowed to revert to G4SLV again, despite living in Scotland. And I can't wait to go back to my “real” callsign!)

I didn't like the original small plastic disc-like knob and at some point, at University in around 1985, I exchanged it for the channel select knob from a Decca Voyager HF SSB Marine transceiver that I had stripped for parts. This is a much larger and heavier aluminium knob which make the key feel much more solid.

The replacement Decca Voyager knob mounting details

The axle (trunnion?) ends are supported by ball bearings, tensioned with springs and the key, for all its cheapness, feels nice and smooth. I've often toyed with getting rid of it and getting something “proper” (a Marconi 365, a PS213, a Junkers, a NATO, or something modern and handmade and brass) but I keep coming back to it and don't see the need to replace it. Of course a small collection of keys is still an option, for interest and variety, but not a necessity while I have this one.

Modern version

I noticed recently that the currently available version of the HK-708 is significantly different to my old one from 40 years ago.

The new one has the same small disc-like knob (which I didn't like) but the main lever is straight, not curved downwards at the knob and I see that the tension spring is forward of the axle, towards the front of the key, so it must be in compression, rather than tension. Whether that makes a difference to the feel, I don't know. I also don't know if the pivots are still ball-bearings or simple bushes. I don't think I'll risk getting a new one to keep on hand in case of need!

Python module for netradio

Some functions aren't needed for receive only, and should be removed (ptt_on ptt_off etc.). This module originally came from another project (not “object oriented”) and I had to add lots of self statements to the needed functions, ignoring the ones not used for “netradio”. I'll trim it, later, if I remember.

Kenwood TH-D72

anonymous@undisclosed.example.com (Anonymous) — Thu, 04 Jun 2026 06:39:56 +0000

←Rig and Key List

Kenwood TH-D72

Remote Control

The TH-D72 can be used to remotely control a TM-D710. This allows remote control of VHF Frequency/Memory Channel, TX power, CTCSS/DCS tones and to enable/disable cross-band repeat.

The remote control function uses specific DTMF sequences to instruct the TM-D710.

To enable “Remote Ctrl” mode :

Select the correct UHF uplink frequency to match the TM-D710
Turn off the TH-D72
Hold MR and PTT
Turn on the TH-D72

The display will show “Mobile Ctrl”

The TM-D710 must also be put in Remote Control mode.

On the TM-D710

select VHF mode on both sides
turn off the APRS TNC if it's on
set the left side to the wanted VHF Frequency
set the right side to the UHF Uplink/control frequency to match the TH-D72
- the first steps are done by selecting PM5 on my TM-D710
- make sure the left side/VHF is the “active” side by clicking the left volume knob
turn off
hold Rev button
turn on

The TM-D710 should now be in remote mode.

To restore normal operation repeat the same sequence of

Turn off
Hold Rev
Turn on

Successful commands sent to the TM-D710 will receive a “pip pip pip” revertive.

The commands are send using the TH-D72 keypad, remapped as:

1 = DCS On	2 = Tone On	3 = CTCSS On	A = Enter
4 = DCS Off	5 = Tone Off	6 = CTCSS Off	B = CTCSS/DCS Tone
7 = Call Ch. Mode	8 = VFO Mode	9 = Memory Mode	C = Repeater On
* = Down	0 = Power	# = Up	D = Repeater Off

to change VHF Frequency to 145.500
- 8 (VFO Mode)
- A (Enter) 145500 A (Enter)
to change to memory channel 2
- 9 (Memory Mode)
- A (Enter) 002 A (enter)
To turn on Cross-Band Repeat
- C
To turn off Cross-Band Repeat
- D

Once the TM-D710 is in the correct condition - VHF Frequency, tone, power, cross-band repeat - it's possible to restore the TH-D72 to normal operation and use it to access the cross-band repeater and use DTMF tones as normal (eg. to control another system via the repeater). Just exit “Mobile Ctrl” mode on the TH-D72

Turn off
hold MR and PTT
Turn on

You should be back in normal operation mode.

Obviously, to control the TM-D710 again (eg to disable cross-band repeat) simply go back to Mobile Ctrl mode in the same way, and send the required commands.

Vibroplex Presentation Bug

1957 Presentation Model

Bought : ? , eBay
Cost : ?
Serial Number : 198474
Date : 1957
Plate : D6

Features the “La Hiff” adjustable mainspring, which was only used on the original “genuine” Presentation models.

Details

This was my first bug key and has had to have some work to repair damage to the frame. The tapped holes for the screws that hold the frame to the base were stripped, and the frame couldn't be tightened sufficiently to the base. I found the easiest (although not invisible) way to fix it was to drill through the original holes, all the way, and then tap a new thread (M6) and use longer screws to secure the frame to the base. This has spoiled the key's “original” appearance, but made it actually useable as a bug key, which to my mind is much more important. I'm sure old-time professional bug users would make whatever repairs were necessary to keep their favourite keys in operation, caring little of maintaining “originality”. You can see one of the protruding bolts here:

60m

A return to 60m in earnest

I've been active on 60m since it was first available (with a NOV) - and mostly in Digimodes on FK / 5366.5kHz, along with a bit of CW and very little SSB. For many years 60m digimodes was the only activity I did on the radio. In recent years I've been largely QRT, or having the odd spell on CW, but I still have an interest in 60m as a place for experimentation and for inter-UK communications. 2024 will be my year of 60m, with more SSB operating.

Band Utilization

Captured well by G3NRW's chart uk_60m_5_mhz_band_utilization_chart_band_plan_by_g3nrw.pdf
Since this chart was first produced many more European countries have access to 60m - mostly using the WARC allocation 5351.5 → 5366.5
The UK was first to have access to 60m but we are now out of touch with how the band is developing, locked in our unique set of bandlets.
Digimodes among UK stations still takes place on 5366.5kHz (USB Dial) which is an RF centre frequency of 5368.0. This is therefore out of the WARC allocation.
- Many Eu hams choose to ignore this - the WARC allocation goes to 5366.5kHz and if they set their radios to 5366.5kHz they operate there ignoring the fact that their actual signal is out of band.
- I tend to just work them and leave them to juggle the legalities.
I still see the band as interesting mainly for it's use as quiet, mostly channelized band for inter-UK experiments, rather than a band for “working DX”.
The WARC band has evolved its own internal band-plan.
- IARU Bandplan including 5MHz WARC hf_r1_bandplan.pdf

UK : Occupancy versus Bandlet/channel

I plan to investigate which bandlets are used for amateur QSOs and where/when any non-ham, commercial, military and UNID activity blocks access to our allocated spectrum.
- Which bandlets are clobbered regularly?
- Which bandlets have clear SSB channels most of the time?
- Where are the regular amateur nets, QSOs, CQ calls?
