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.

-1.6584 x10 ^-10

User Programs can be saved/loaded via USB Serial port using a terminal emulator such as Putty

LF15C uses binary floating point representation, rather than the more common BCD.
- This improves the speed but introduces occasional small rounding errors

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.

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.

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.

Hardware / Firmware issue

I received the following email from Swiss Micros in 8th March 2024 explaining a hardware change that's required to early production units to ensure correct operation with the latest firmware, which allows the processing speed to increase when powered via USB (as per the DM41X and DM42).

email re: hardware mod

Dear valued customer,

We appreciate your decision to purchase the DM32 calculator.
As one of our early adopters, your support means a lot to us.

In our initial firmware versions, we restricted the CPU speed
to 48MHz due to power limitations from the CR2032 battery.
However, in upcoming firmware updates, we're introducing the ability
to switch to 160MHz when powered by USB. It's crucial to note that
upon unplugging the USB, the CPU speed must swiftly revert to 48MHz
to prevent battery voltage drop and subsequent CPU resets.

Regrettably, we've identified an issue affecting units purchased
before December 2023. In specific scenarios, the CPU speed doesn't
transition quickly enough, potentially leading to calculator resets.

This may happen upon USB disconnection if the device is engaged in
processing tasks rather than merely awaiting user input or being powered down.

All units ordered post-November 2023 have been enhanced to ensure consistent
performance. This modification entails replacing R4 with a 22k resistor
instead of the previous 100k one.

To address this issue, we offer several solutions:

If you're comfortable soldering, replacing R4 is a straightforward fix. We're happy to dispatch a replacement
resistor to you in an envelope, see https://www.swissmicros.com/product/r4-22k-resistor

Alternatively, you can send your DM32 to us, and we'll replace the resistor and return it to you promptly,
see https://www.swissmicros.com/product/rma

We anticipate a new batch of PCBs to be available in approximately three months. Once ready, we can send you
a replacement PCB. We kindly request that you return the replaced PCB to us.

https://www.swissmicros.com/product/dm32-replacement-pcb

We sincerely apologize for any inconvenience caused and appreciate your
understanding and cooperation in resolving this matter.

Thank you for your continued support and patience.

Best regards

Michael Steinmann

SwissMicros

I find the DM32 plenty fast enough running on batteries, so I'm not necessarily going to be plugging it it to boost its performance but I do want to stay up to date with firmware changes and don't want to risk any problems, so I've ordered the replacement SMD resistor and plan to swap it myself.

update 24/01/26 - I think I did the swap…. after receiving the new resistor, not sure of the date…. I'm fairly sure I did, anyway!

Generally I find C47 to be sluggish and laggy and although the features are great the User Experience is poor.
- The Dev. Team seem to spend more time adding new features/functions and don't really care that it's very slow
- Reports indicate that the DM42n runs C47 much faster

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

rxPort = 34001                ; Listen for USRP frames on this port

It should match Asterisk's private node as defined in /etc/asterisk/rpt.conf - in this case it's [1398]

[1398]
rxchannel = USRP/127.0.0.1:34001:31001 ; Use the USRP channel driver. Must be enabled in modules.conf
 ; 127.0.0.1 = IP of the target application
 ; 34001 = UDP port the target application is listening on
 ; 32001 = UDP port ASL is listening on

Make Sure Analog_Bridge.ini has the correct txPort and rxPort in its [AMBE] section

[AMBE_AUDIO]
address = 127.0.0.1                     ; IP address of xx_Bridge
; For DMR  - match the ports set in DVSwitch.ini
;txPort = 31103                          ; Transmit TLV frames to partner on this port
;rxPort = 31100                          ; Listen for TLV frames from partner on this port

; FOr NXDN - match the ports set in DVSwitch.ini

rxPort = 33100                          ; Listen for TLV frames from partner on this port
ambeMode = NXDN                          ; DMR, DMR_IPSC, DSTAR, NXDN, P25, YSFN, YSFW (encode PCM to this format)

should match the ports in DVSwitch.ini [NXDN] section

Set Callsign in NXDNGateway.ini

I don't know what Suffix means, I left it as found
Set the NXDN talkgroup in Analog_Bridge.ini
NXDN Talkgroups are listed here : https://www.pistar.uk/nxdn_reflectors.php
- A Talkgroup actually seems to specify a particular reflector IP address/Hostname & UDP port
- These are retrieved by NXDNGateway from the hostfile : /var/lib/mmdvm/NXDNHosts.txt
- Setting the txTG=23551 in Analog_Bridge.ini causes NXDNGateway to make a connection to the relevant reflector when you send traffic by keying up.
- For example TG23551 (Scot-Multi) appears in NXDNHosts.txt as:

23551   nxdnscotland.ddns.net   41400

Having txTG=23551 in Analog_Bridge.ini causes DVSwitch to connect, and start to flow packets, with nxdnscotland.ddns.net:41400

Updating DVSwitch Hostfiles

DVSwtich keep its hostfiles in /var/lib/mmdvm and updates via cron.daily/DVSM_Update which calls /opt/MMDVM_Bridge/dvswitch.sh update
This tries to download hostfiles from various places using curl
It seems to fail most of the time due to a SSL problem
A workaround is to put “insecure” in root's ~/.curlrc

 
gm4slv@node481482:~$ sudo su -
 
root@node481482:~# echo insecure >> ~/.curlrc
 
root@node481482:~# /opt/MMDVM_Bridge/dvswitch.sh update

Analog_Bridge.ini

; Analog_Bridge configuration file.
;   This file should be placed in either /etc or it can be
;   supplied as a path on the Analog_Bridge command line.

; The best way to think of this file is that there are two main sections, the USRP (analog audio) and
; AMBE_AUDIO (compressed audio).  Analog_Bridge will take everything sent to the USRP port and
; encode it for transmission on the AMBE_AUDIO port.  The encoder will use the format defined in ambeMode.
; As you might expect, the reverse direction is defined too.

; Analog_Bridge supports include files. More on this later...

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.

#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.

Music - A Return To An Old Hobby

anonymous@undisclosed.example.com (Anonymous) — Sun, 19 Apr 2026 08:45:07 +0000

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.

Laptop Backup via rsync

Laptop Backup via rsync

A simple way to keep a backup of my laptop Home directory

Backup hosts

where to put the backups for safe keeping

A NAS box on my home LAN : nas1
An old Lenovo Laptop acting as a LAN file server : laptop
My cloud VPS server : g4slv.info

Rsync Script

To automate the backup to any of the three backup hosts above I've got a script, obviously.

The script checks which hosts are currently online and reachable and backs up the same data to each of them. This check means any of the hosts can be turned off but the script won't simply hang waiting for connection timeout before trying the next hosts.

To reduce the traffic, and to limit backing up needless data (i.e. don't just backup the whole of $HOME) I have an exclude file that lists files and directories that should be ignored.

The backups are saved in a remote Directory called “devuan” - the laptop being backed up is running Devuan linux and has the hostname devuan

I also backup a mirror of the wiki to the local NAS and Laptop hosts (as long as I remember to pull a backup/mirror down from the wiki server first). There's no point in backing this up to the remote VPS - since that's the machine where the wiki lives in the first place!

#
 
# The NAS1 destination is a share called  Backups
# which is accessed via "daemon rsync" at nas1::Backups
# rather than a directory in /home/g4slv
# this allows passwordless rsync. Necessary since the ssh
# server @ nas1 is too old to accept identity keys from
# modern ssh clients - so normal rsync-over-ssh would require
# a password.
#
# Using a "module" overcomes this, and allows for automatic

then

Dokuwiki Mirror/Backup

I have a script to pull a copy of the dokuwiki files from the VPS and put them in /var/www/html/* on my laptop. The laptop runs apache2 and can server the wiki itself. This mirror can be backed up through the above script to the other backup hosts nas1 and laptop

#!/bin/bash
 
rsync -av -e "ssh -p xxxx" --progress  xxxx@g4slv.info:/var/www/html/dokuwiki/ dokuwiki/
 
sudo rsync -av dokuwiki/ /var/www/html/dokuwiki/
 
sudo chown -R www-data:www-data /var/www/html/dokuwiki

Fldigi Parrot

Fldigi Parrot

Experimental HF Digi-mode message-relay system using Fldigi and Python

Work in progress

Uses xml-rpc in python to communicate with fldigi and read the incoming RX Text.

When a particular text sequence is received (ZCZC CALL CALL) to trigger the “parrot” function, the RX text is then read searching for an end of message string (…end). When this is found the full message is then re-transmitted, with self-identification added to ensure it is clear which station is the source of the message and which is the source of the relay.

Transmitter control via RS232 / NMEA (for an IC-M710 marine HF transceiver) is also included to allow for remote commands to change frequency to be handled. Fldigi does the rig control (via its own hamlib configuration). Fldigi is told what we want the radio to do via xml-rpc rather than have direct control ourselves.

Monitoring

A web-page is provided that shows the Fldigi receive text, in almost real time at:

~~Fldigi RX Text~~

and another shows the parrot activity:

~~Fldigi Parrot~~

Software

The python scripts to run these functions are run within a tmux session which is set up with the following script:

tmux script

fldigi_xml.sh

#!/bin/sh
 
session="Shack"
 
tmux start-server
 
tmux new-session -d -s $session 
 
tmux rename-window "fldigi"
 
tmux selectp -t 0
tmux send-keys "python2 ./rx_buf.py" C-m
 
 
 
tmux selectp -t 0
tmux splitw -h -p 50
tmux send-keys "python2 ./parrot_flmsg.py" C-m
 
tmux selectp -t 1 
tmux attach-session -t $session

The python scripts

rx_buf.py
parrot_flmsg.py
flfn.py

are as follows:

rx_buf.py

rx_buf.py reads the Fldigi RX Buffer and provides the online web page to allow remote observation of what is being received.

parrot_flmsg.py

parrot_flmsg.py handles the message-relay functions.

Recent changes were made to handle the longer formal message formats of flmsg.

The parrot also provides some simple remote control of the HF transceiver's frequency and power level via QSY? and PWR? commands.

Parrot Operation

Basic overview

To trigger a message relay you need to send the following format of text:

ZCZC GM4SLV <YOURCALL> (replacing <YOURCALL> with your actual callsign)

This is the start of message trigger.

Then type/paste/otherwise send your message-to-be-relayed.

To end the message send:

… end

If you are using flmsg to to create and send the message it will send the correct end of message string … end itself, otherwise you need to add it manually.

After a short delay, if successful, you should hear/see your message being relayed.

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 manual for the HP16C Module hp_16c_emulator_manual.pdf

The versions of modules I'm using : hp-16c_rev.1a.zip

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…..

Svxlink Update (Dual Gateway)

Svxlink Update (Dual Gateway)

— John Pumford-Green 02/06/22 19:56

To allow testing and comparison between 2m and 70cm I've got two SVXLink gateways running.

MB7AZE : 70cm : 430.050MHz @ 3W using FT-60
GM4SLV : 2m : 144.625MHz @ ??W using FT-8900

Both feed the same dual band colinear via a duplexer.

Both are connected to G4NAB's SVXReflector http://svxportal-uk.ddns.net:81/index.php

(UPDATE — John Pumford-Green 03/06/22 09:05)

I now realize that the DTMF problems were due to setting de-emphasis ON while actually using the audio feed from the FT-8900 for 1200 packet, which already has de-emphasis applied. So I was doing double-de-emphasis.

No wonder the tones were being mangled.

The ~~deleted~~ section below shows what steps I took to restore the tone detection in this situation, but this isn't actually necessary if the correct audio feed is used. The quick-fix is to turn SVXLink's de-emphasis OFF and restore the DTMF twist to its normal value. The better fix will be to re-wire the interface to use the flat 9600 baud audio and restore SVXLink's de-emphasis.

Some tweaks were necessary to get GM4SLV to work - DTMF detection was flaky on certain digits when RX de-emphasis was enabled - which is necessary when using the 9600 packet flat-audio feed from the FT-8900. The issue seems to be the roll-off of the de-emphasis affecting the DTMF digits that use the widest spaced tone-pairs. There's are configuration items that can fix the problem: DTMF_MAX_FWD_TWIST and DTMF_MAX_REV_TWIST in the [Local Receiver] section. I had to set DTMF_MAX_FWD_TWIST to 15 to fix the problem.

The GM4SLV gateway now uses the FT-8900 via an unmodified CM108 sound dongle.

The PTT is from GPIO25 and SQL is from CTCSS.

I've swapped the Echolink service from MB7AZE-L to GM4SLV-L.

For the next period of testing MB7AZE will be lower profile, and the FT-60 handheld can not handle long periods of transmitting (e.g. when set on HUBNET or similar).

The start-up script that also sets up GPIO (for PTT):

#!/bin/bash
 
CFG=/usr/local/etc/svxlink/svxlink.conf
LOG=/home/gm4slv/svxlink.log
 
sudo killall svxlink
sudo killall svxlink
sudo killall svxlink
 
echo "25" > /sys/class/gpio/export
 
sleep 2
 
echo "out" > /sys/class/gpio/gpio25/direction
 
sudo svxlink --daemon --logfile=$LOG --config=$CFG
exit 0

crontab to start it at reboot

@reboot sleep 30 && sudo -u gm4slv /home/gm4slv/svx_ref.sh >/dev/null 2>&1

Privacy ?

anonymous@undisclosed.example.com (Anonymous) — Sun, 19 Apr 2026 08:45:35 +0000

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”*

The initial node, described here → GM4SLV Allstar 2025 got too cumbersome after adding DMR Bridging, along with handling Echolink.

I decided, since I had a few spare Raspberry Pi boards doing nothing much, to split the DMR Bridging to a separate node.

I removed the DVSwitch bridging from the VHF Gateway node and changed its node ID to 481480 (NNX)

DMR Bridging Node

Platform	Raspberry Pi 4 Model B Rev 1.5
OS	Debian GNU/Linux 12 (bookworm)
ASL Version	3.7.1-1.deb
Allstar Node	481481
Dashboard	http://gm4slv.plus.com:42111/

New hardware and OS install

Installed OS first Pi OS 64 bit Lite →

Pi OS Lite

then the ASL repository and finally ASL3 and Allmon3 following guide at:

https://allstarlink.github.io/install/debian/install/

I found this much nicer than the “Pi Appliance” method.

This one is for running DVSwitch to bridge to (at the moment) TGIF TG2354429 (my so-called ID Talkgroup )

I added the DVSwitch software, in the same way described here GM4SLV Allstar 2025 (using bookworm in place of buster) and decided to bridge to TGIF instead of Brandmeister.

I also decided to use the md380_emu emulator for the AMBE transcoding.

;   rxchannel = usrp/127.0.0.1:34001:32001

Svxlink & Echolink

Revisiting the Analogue FM Voice Gateway

Svxlink Gateway Initial Setup

Trying not to re-invent the wheel

find saved Pi Image File for a previous Svxlink system
copy to a new SD Card and boot a spare Raspberry Pi with it
find and connect a modified CM108 sound-dongle - has PTT and SQL via the dongle's own GPIO
connect to 2m FM radio and test initial config
make any necessary config changes - e.g. MB7AZE → GM4SLV
set up audio levels using devcal
change to 9600 packet interface on 2m radio to remove radio pre/de emphasis and apply pre/de emphasis in Svxlink
set up audio levels again using devcal
Check connectivity to Echolink
- remember to Port Forward on ADSL router : UDP 5198 & 5199 → svxlink Pi's IP address
- consider using a private proxy on my VPS instead? Java JRE and Echolink Proxy

Pi Image File handling

R Pi Image files

Devcal

devcal
remember to sudo killall svxlink to ensure no daemon svxlink processes are running in the background
remember to adjust path to valid svxlink.conf file which will be different to this old example
Set for 3kHz deviation
remember to edit the config file(s) to change the RX Pre-amp and TX Master Gain settings to match those find using Deval

sudo devcal -r -m=3000 -d=3000 /etc/svxlink/svxlink_noel.conf Rx1

sudo devcal -t -m=3000 -d=3000 /etc/svxlink/svxlink_noel.conf Tx1

add the PRE_AMP and MASTER_GAIN settings to both svxlink_el.conf and svxlink_noel.conf

Config Files

One for Echolink Enabled
One for Echolink Disabled
Switch Echolink on/off via DTMF commands
- Edit Logic.tcl to give this functionality

Edit the section proc dtmf_cmd_received {cmd} to add the stanzas that run external bash scripts to stop and restart svxlink with different config files

#
# Executed when a DTMF command has been received
#   cmd - The command
#
# Return 1 to hide the command from further processing is SvxLink or
# return 0 to make SvxLink continue processing as normal.
#
# This function can be used to implement your own custom commands or to disable
# DTMF commands that you do not want users to execute.
proc dtmf_cmd_received {cmd} {
  #global active_module

  # Example: Ignore all commands starting with 3 in the EchoLink module.
  #          Allow commands that have four or more digits.
  #if {$active_module == "EchoLink"} {
  #  if {[string length $cmd] < 4 && [string index $cmd 0] == "3"} {
  #    puts "Ignoring random connect command for module EchoLink: $cmd"
  #    return 1
  #  }
  #}

  # Handle the "force core command" mode where a command is forced to be
  # executed by the core command processor instead of by an active module.
  # The "force core command" mode is entered by prefixing a command by a star.
  #if {$active_module != "" && [string index $cmd 0] != "*"} {
  #  return 0
  #}
  #if {[string index $cmd 0] == "*"} {
  #  set cmd [string range $cmd 1 end]
  #}

  # Example: Custom command executed when DTMF 99 is received
  if {$cmd == "99"} {
    puts "Executing external command"
    playMsg "Core" "online"
    exec /home/gm4slv/svx_noel.sh &
    return 1

crontab entry to start with echolink enabled at boot time

@reboot sleep 30 && sudo -u gm4slv /home/gm4slv/svx_el.sh >/dev/null 2>&1

Catch up with git version

The version of svxlink running on this Pi was self-compiled from the GIT repository
- Update to latest version from GIT
I decided to pull & compile the latest version so I simply followed the instructions I'd put on the above wiki page and all went smoothly (if slowly)

DTMF Commands

Old info SVXLink : DTMF commands
Ignore Reflector commands - I am not (yet) connected to the SVX Reflector http://svxportal-uk.ddns.net:81/index.php

`*#`	System Status
`0#`	Help Module
`1#`	Parrot Module
`2#`	Echolink Module

`#`	De-activate module

Echolink Module

`<node number>#`	Connect to `<node number>`
`0#`	Play the help message
`1#`	List all connected stations
`2#`	Play local EchoLink node id
`31#`	Connect to a random link or repeater
`32#`	Connect to a random conference
`4#`	Reconnect to the last disconnected station
`50#`	Deactivate listen only mode
`51#`	Activate listen only mode
`6*#`	Use the connect by callsign feature
`#`	If connected = Disconnect, otherwise = Deactivate Echolink module

https://github.com/sm0svx/svxlink/wiki/ModuleEchoLink

Macros

`D1#`	Echolink	9999	Echotest
`D2#`	Echolink	973498	M0HOY-L	Hubnet
`D3#`	Echolink	662666	M0JKT-L	FreeStar

Sound files

use en_US when echolink is enabled
- this is also needed for reflector when it's re-enabled, as the US files also have the additional reflector sound samples
use en_GB when echolink is disable
easy to tell from status *# which is active!

Proxy

after consideration….
I decided to use my VPS-hosted echolink proxy

QRSS

QRSS

I've been running my QMX on WSPR, using its DigiMode and the USB interface to a laptop running WSJT-X, when I'm not using for real QSOs.

But I got to thinking “is that all there is?”

I've seen almost continuous QRSS signals on the WSJT-X waterfall on 30m while running WPSR, and I remembered running a grabber on 600m/500kHz back in the early days of access to that band, and I wondered what activity there still was using QRSS. So I looked around the 'net and found that the “QRSS Knights” group are still going and I wondered about joining it. It would give a more human interaction and more human use of the “down time” - I could still monitor propagation, but not using the computer to do everything… you still need to actively look at the waterfall and read the morse code from the noisy trace on the screen.

I've joined the Knights QRSS on groups.io https://groups.io/g/qrssknights and last night I set about getting a grabber up and running.

I settled on good old Spectrum Lab which I know has always worked well under Wine on Linux. After a bit of fiddling I got a working setup to display the “QRSS Watering Hole” on 30m, my band of interest, and then fiddled with some bash scripts to automate the “grab and upload” function to send images to my website. https://g4slv.info/

On this image from 10:20UTC today there are several QRSS signals….

From the top:

S52AB
G0PKT
M0BMN
G0MBA
G4JQT
IK2JET

I tried sending some QRSS at 1W this morning for an hour or so, but only saw the faintest of traces on the grabber of Fabian (DJ5CW) on his Polish-sited Grabber SO5CW which might have been me.

Once again, it seems that my quiet location is better for receive than transmit.

My grabber is now included on the grabber list at https://swharden.com/qrss/plus/ so let's see what appears on my screen.

I'll put some details of the simple bash scripts that do the uploads on the main wiki Radio pages, and add more info about QRSS there, when I get a chance.

Update

I ran on TX again in the afternoon and Fabian DJ5CW/ SO5CW confirmed reception in Poland!

The “L” really pops out at one point!

Benchmarking

Various methods to test the speed of calculators

HP Museum Benchmarks

These pseudo-code examples need tweaking for each calculator, some have alpha register names, some numeric.

The handling of the <loop> is different in each calculator,too.

The Programs are run for 1 minute and the result (the number of loops completed) is found in register 2 (or wherever is used in the calculator being tested).

For single loop (slow calculator) simply XEQ A

Result is the time to complete the loop(s) and deliver the answer 0.264577

Performance Index is calculated as

Loops x 34 / Time

For 1000 loops in 13 seconds:

1000 x 34 / 13 = 2615.38

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

DM41X 41z Module

Keyboard Overlay

Setup

assign the complex keyboard Z i.e. function ΣZL to USER menu on key Σ+
- SHIFT ASN ALPHA SHIFT F Z L ALPHA Σ+
  - SHIFT F is the method of getting Σ from the ALPHA keyboard (see the back of calculator)
- Enter USER mode with USR key
- The Σ+ now activates a complex number function when it's pressed - for one operation only

The rest of the guide was written without the use of full-time ZKEYS in mind

in the forum thread dealing with the factorization bug in the deluxe version Angel recommended I use the ΣZL method. He fears that occasionally ZKEYS might be broken with incorrect/missing USER assignments - so I'll try to stick to the normal ΣZL method.

Quick Ref

Z = Σ+

↑IM/AG = Z XEQ
ZREAL↑ = Z Z RCL
ZIMAG↑ = Z Z XEQ
ZINV = Z 1/X
POLAR = Z Z R→P (i.e. 6)
RECT = Z Z P→R (i.e. 5)
ZCONJ = Z SHIFT CHS (complex conjugate)
Z ^ X = Z EEX
Z ^ 1/X = Z Z EEX (root(s) of complex number) : see Cubic Roots
- ZNXTNRT _ = Z Z SHIFT √x NEXT ROOT enter the root you want
ZWDOT = ZZ. : dot product of 2 vectors/complex numbers
ZWCROSS = ZZ2 : Magnitude of the Cross Product of 2 vectors/complex numbers (no sign)
ZWDET = ZZ7 : Determinant (Cross Product) of 2 vectors/complex numbers, incl. sign/direction

Basic Operation

enter two numbers and add them together

The ''natural'' entry method

Enter a complex number to the stack
- 5 + j 20
  - 5 Z XEQ 2 0 ENTER
    - Z XEQ is ^IM/AG - set the imaginary part
add a second number to the stack
- 10 - j 32
  - 10 Z XEQ 3 2 CHS ENTER
add the two numbers together
- Z +
15 - j 12

Enter a real number

2.75 + j 0
- 2.75 Z Z RCL

Enter an imaginary number

0 + j 3.1415 (i Pi)
- SHIFT π Z Z XEQ

Use it to calculate with....

calculate e^iπ
- Z SHIFT e^x
- - 1 + j 0
- e^iπ = -1

Parallel Impedances

This involves the complex inverse function Z 1/x

Z1 = 50 + j 13 in parallel with Z2 = 23 - j 85
- enter Z1 50 Z XEQ 13 ENTER and invert it Z 1/X
  - 0.02 - j 4.87E-3
- enter Z2 23 Z XEQ 85 CHS ENTER and invert it Z 1/X
  - 2.97E-3 + j0.01
- add them together Z +
  - 0.02 +j0.01 and invert Z 1/X
    - 42.72 - j 11.99

convert to Rectangular ⇔ Polar operation

Z = 50 - j 23
initially in rectangular form…¹⁾
- enter Z as usual
  - 50 Z XEQ 23CHS ENTER
- convert to Polar format
  - Z Z 6 ( 6 is R→P but needs two presses of Z to activate it)
  - 55.04 ∠ -24.70
- convert back to Rectangular operation
  - Z Z 5
  - 50 - j 23

enter a number directly in Polar format

To enter 5 ∠ 53.13 directly
- switch to Polar format Z Z 6
- enter Mag / Angle:
  - 5 Z XEQ 53.13 ENTER
  - display : 5 ∠ 53.13
convert to Rect
- Z Z 5
  - display : 3.00 + j 4.00

Cubic Roots

Rectangular

enter complex real number -8 + j 0
- 8 CHS Z Z RCL
  - -8 + j 0
- enter 3 (goes into the normal X register)
- find the result of Z↑1/x
  - Z ZEEX
    - 1 + j 1.732 (the first of the cube-roots of -8)
- find the next root with the function ZNXTNRT
  - Z Z SHIFT√x
  - enter 3 at the _ prompt
    - -2 + j 0
- find the next root with the function ZNXTNRT
  - Z Z SHIFT √x
  - enter 3 at the _ prompt
    - 1 - j 1.732

The 3 cube roots of -8 are

1 + j 1.732
-2 + j 0 (the basic real cube root)
1 - j 1.732

Polar

enter complex real number -8 + j 0
- 8 CHS Z Z RCL
  - -8 + j 0
  - convert to POLAR
    - Z Z6
      - 8 ∠ 180
- enter 3 (goes into the normal X register)
- find the result of Z↑1/x
  - Z Z EEX
    - 2 ∠ 60.000 (the first of the cube-roots of -8)
- find the next root with the function ZNXTNRT
  - Z Z SHIFT √x
  - enter 3 at the _ prompt
    - 2 ∠ 180
- find the next root with the function ZNXTNRT
  - ZZSHIFT√x
  - enter 3 at the _ prompt
    - 2 ∠ -60.000

The 3 cube roots (in POLAR) of -8 are

2 ∠ 60.000
2 ∠ 180
2 ∠ -60.000

Alternate input method

BEWARE

key Imaginary part first & press normal ENTER
key real part (and no ENTER)
do complex enter (Z ENTER) or another complex function (e.g. Z +) (be careful with the stack lift or it gets confusing)
e.g. 52 + j 36
- 36 ENTER 52 Z ENTER
- 52 + j 36 is now in Stack
enter second number
e.g. 23 - j 15
- 15 CHS ENTER 23 (don't Z ENTER this…!!)
to add them together use Z + now (instead of Z ENTER)
result : 75 + j 21

gotcha

pressing Z ENTER after the second number (instead of the required complex function) will give you

Stack value	Stack
	U
52 + j 36	V
23 - j 15	W
23 - j 15	Z

doing a Z + now will add the second number to itself and the result will be 46 - j 30

This is normal RPN stack behaviour, but is confusing when you're building complex numbers.

use ↑IM/AG instead

The natural entry mode is much better

you enter the real and imaginary parts in the order you expect them
the stack operation is less obscure.
It just seems more intuitive.

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.

Solve with an Integral

from HP34C manual pp233
Solves Bessel function for Bessel-zero mod. index value

differs from the DM15L (HP15C) version because the Integration Accuracy estimate is very small so the test of x < = y? will never be true
instead we store a required ACC value (much like in the HP42S/DM42) in R001 and test against this instead

Limits 0 → 1 answer -1.000
Limits 0 → 1 answer 3.6490 E-2
Limits 0 → 2 answer 3.1416
Limits 0 → π answer 2.1102 E1
Limits 0 → 1 answer 5.0000 E-1 (rads mode)
Limits 0 → 1 answer 2.0000
Limits 0 → 1 answer 7.8540 E-1
Limits -1 → 1 answer 2.3857 E-2
Limits -1 → 1 answer 2.2033

Using FIX10 still allows the integrations to complete almost instantly except for Program 8 which takes around 8 seconds!

Dropping to FIX08 and program 8 integration completes almost instantaneously too. Strangely Program 8 has some odd behaviour regarding display precision.

FIX04 → FIX07 → instantaneous answer 0.5000….
FIX08 → instantaneous answer 0.50000….
FIX09 → 8 seconds answer 0.499964689
FIX10 → 8 seconds answer 0.4999747623
FIX11 → 10 seconds answer 0.49999489949
FIX12 → 10 seconds answer 0.499999962001
FIX13 → instantaneous answer 0.5000……
FIX14 → instantaneous answer 0.500000……
FIX15 → instantaneous answer 0.5000000……

Pure Blog

I've installed Pure Blog

After trying the Blog Plugin in dokuwiki and Chyrp-Lite PHP/SQLite blogging platform I switched to Pure Blog.

It's just what I need, and nothing extra to make it big and bloated.

Installation & Configuration

See https://g4slv.info/installing-pure-blog for some info.

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.

Monobook user/screen.css

Dokuwiki Template CSS

Standard settings for font sizes etc. for different elements is here:

/var/www/html/dokuwiki/lib/tpl/dokuwiki/css/design.less

add any modified tweaks to the CSS to a userstyle.css i.e. /var/www/html/dokuwiki/conf/userstyle.css

font-size etc

pre {
        border-radius: 10px;
        background-color: #fcffff
}
 
 
code {
    color: #c72522;
    font-size: 1.1em;
    padding: 0.1em 0.3em;
    border-radius: 0px;
    }
 
 
.dokuwiki .aside {
    font-size: 90%;
    }
 
 
body {
    font-size: 90%;
 
}
.dokuwiki div.breadcrumbs {
    font-size: 90%;

Dokuwiki Template Tagline

<p style="font-size:12px;background-color:#a5e4fa;">Try to learn <b><i>something</i></b> about everything, and <b><i>everything</i></b> about something <br> <i> -Thomas Huxley “Darwin's bulldog” (1824-1895)</i></p>

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];
    //}

jpg upload error - XML

Media manage red warnings when uploading jpg image files

Error: Call to undefined function xml_parser_create()

New VPS was missing the php-xml package.

sudo apt install php-xml
sudo service apache2 restart

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.

Add folded plugin

make a clickable hide/reveal section with

++++ visible text | hidden text blah blah ++++

e.g.

There is a table here...

Col1	Col2	Col3
one	two	three

def func():
    print "hello world"

Increase TAGCLOUD font size

edit /var/www/html/dokuwiki/lib/plugins/cloud/style.less

increase size factor

/* Size factor. */
@sF: 1.2;

force re-fresh of browser to show new font size.

Keyboard Plugin

tweak the size, border and colour

example keys

Ctrl+C

}

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;
    border-radius: 0;
    }

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;
         background-color: #fcffff
 
}
 
code {
    color: #c72522;
    font-size: 1.1em;
    padding: 0.1em 0.3em;
    border-radius: 0px;
    }

Remove Dokuwiki template footer buttons

edit /var/www/html/dokuwiki/lib/tpl/dokuwiki/tpl_footer.php

comment out (  ) the license stanza and/or the <div> that contains the “buttons”

<?php
/**

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.

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")){

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;
}
 
/*

Getting back into radio

I've got the radio bug again

HF

New HF antenna - simple vertical on a 10m Sota-Pole after the old Racal mast holding up the Inverted-L collapsed this winter
- improved ground/radials (6/4/25)…. more work to be done
Going back to “the old days” where I used 'phone more often
Putting aside the CW keys/bugs for a while
- and also digimodes put to one side
New HF Rig : FT-891 for SSB and 10m FM 'phone operation
Portable “go box” with G90 being re-assembled
- New 7m Sota-Pole for portable operation

Other bands/modes

DMR back online at home
- Full Duplex 2-timeslot hotspot
- Anytone 878
2m APRS I-Gate running again GM4SLV-2
VHF and APRS mobile GM4SLV-9 with TM-D710

6502 based homebrew computer

— John Pumford-Green 17/09/22 12:29

I started a new project last month. I'd been thinking of what to use my new DM16L for, apart from simple Decimal to Hex to Binary conversions.

In a roundabout manner I found the work of Garth Wilson and his excellent resources for 6502 hardware and assembly-language. Then I found the excellent YouTube videos of Ben Eater and I was convinced that I needed to start building and learning 6502. I've always struggled with some aspects of software - it seems too abstract and not rooted in anything hard and physical. I found I enjoyed learning about machine code, and then Assembly, as it is tied very firmly to the hardware, you need to understand what happens on each clock cycle, where the data goes, how it can be manipulated.

And a DM16L calculator is right at home with the bit-twiddling needed to write code at the machine-code/assembly level. After all, the HP16 was originally designed for Programmers back when machine-code and bit-level programming was all there was!

I got a Ben Eater 6502 kit and haven't looked back.

I plan eventually to fix a hardware design, once I've experimented on Vero-board, and perhaps design some PCBs and build it “properly”….

General Info

Since I need reading glasses to be able to tell the time, or use any of the functions, this watch can never be my main timepiece. That role is taken by my Damasko DA36, with its very legible analogue face, which can be read at a glance, without glasses.

UPDATE : Feb 2024

I've gone back to full-time wearing of Varifocals, so I can now read a digital watch again…. so I'm wearing the G-Shock 5610 most of the time.

←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
privatenodes.txt                              100%   79    39.0KB/s   00:00
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
NODE2=node481481.local
NODE3=node481482.local

FAVORITES=/home/gm4slv/favorites.ini
 
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

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
xxxxxxxxxxxx	xxxxxxxxxxxx	xxxxxxxxxxxx

This is how it looks in the source:

^           Table with alignment           ^^^
|         right|    center    |left          |
|left          |         right|    center    |
| xxxxxxxxxxxx | xxxxxxxxxxxx | xxxxxxxxxxxx |

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>
This is some text which contains addresses like this: http://www.splitbrain.org and **formatting**, but nothing is done with it.
</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.

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

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:

RAX
____________________

RAX is the spreadsheet application of DESK15. When starting RAX you are in the
navigation mode, where the number keys work as cursor pad (see below). The
navigation mode is also active when you refer in a formula to a specific cell.

Keys in navigation mode:
  2 4 6 8  Navigation (Down/Left/Right/Up)
  ENTER 5  Edit selected cell, edit new formula cell
  R/S      Define and edit a new text cell
  BSP      Delete cell
  STO RCL  Save/load spreadsheet to/from one of 6 slots
           Please note that a text in the last cell (D8) is used as slot name.
  GSB      Menu: Quit RAX, New sheet, Copy&Glue/Paste, Hex mode (see PLEX)

Keys in edit mode (ENTER to select and quit):
  SST GTO        Cursor left/right
  SUM+           Insert a stack enter command to separate numbers
  BSP            Backspace - delete character
  RCL            Reference (Select reference cell and enter)
  ENTER GSB R/S  Quit edit mode to navigation mode

Keys in text edit mode (R/S):
  2 4 6 8    Navigation (Down/Left/Right/Up)
  7 1 5      Pos1, End, Center
  SST GTO    Cursor left/right
  BSP        Delete character (left of cursor)
  R/S ENTER  Exit text editing mode
  Any other key inserts the selected character.


____________________

FLEX
____________________

The symbolic calculator FLEX has the look and feel of PLEX, but actually
calculates in the first cell of a RAX spreadsheet. Hence you can see and edit
(with R/S) the formula that yields to the result.

Quit FLEX (and go back to the DESK menu) with GSB.

____________________

TTOP
____________________

TTOP is a tabletop calculator that enables (simple) calculations with big
numbers (even in HEX format) with up to 17 digits. If desired two digits are
used for decimals (ie for cent amounts). PLease note that entering decimals
(after pressing ".") always "shifts the pressed number key in".

TTOP supports the following functions:
  + - * / Basic operation
  CHS     Negate TOS (ends number input)
  EEX     Push Y*10^X to the stack (Y*16^X in HEX mode)
  ENTER   Enter number (stack lift) or duplicate TOS
  SWAP    Swap X and Y
  ROT     Rotate 3 stack elements
  BSP     Clear last number
  SQRT    Calculate square root
  SUM+    NAND ~(X & Y) ... useful in HEX mode
  STO RCL Store TOS or push stored number to stack (store 0 to delete)
  GSB     Menu: Quit TTOP, 0/2 decimals, HEX mode


____________________

RULE
____________________

RULE is a simulation of a historic slide rule for reasons of education and
reminiscence.

RULE supports the following functions:
  SQRT /   Slide one pixel left/right
  EXP 9    Slide 5 pixel left/right
  POW10 8  Slide 10 pixel left/right
  POW 7    Slide 20 pixel left/right
  GSB      Quit RULE


____________________

TEX
____________________

TEX is a (very) simple line oriented text editor. But as entering a text with
cursor keys is quite a pain TEX is sufficient to manage a ToDo or shopping list
or some important formulae. Please note that TEX can manage a maximum of 255
characters (with not more than 18 characters per line).

TTOP supports the following functions:
  4 8 3 9  Navigation (Down/Up/PdDown/PgUp)
  ENTER    Edit (top) line
  /        Edit line but split line at cursor position after editing
  *        Join two lines
  - BSP    Delete (top) line
  +        Insert line before top line
  STO RCL  Save/load TEX document to/from one of 6 slots
  GSB      Quit TEX

  To enter a new line after the last line edit with split option (/) and
  leave editor immediately (ENTER).
  To edit a text TEX uses the text editing routines of RAX (see above).

The HP35s

I have two of these - one for the workshop/shed and one for general use. I try to keep them programmed with the same functions mostly.

The HP35s is a useful RPN programmable scientific calculator, with a few annoyances, but I'm glad I've got a couple lying around to play with. Of course it's not possible to interface a computer with the HP35s, so I have no electronic records of my programs. I write everything down in a notebook, in case I need to re-enter it later, but sharing it online isn't quite as straightforward as with the SwissMicros calculators.

Using Solve and Integrate together

from HP343C handbook
DM41X version uses SOLVE and INTEG from Advantage Pac

Create a MYSOLVE wrapper that handles putting the correct SOLVE program name in ALPHA etc
Create the program that is to be solved and which has as it's function an integral
Create the program that defines the integral

LBL ¬MYSOLVE
¬MOD                    // the label of the program to be solved is put in ALPHA
SOLVE                   // we XEQ SOLVE (the Advantage Pac solver)

LBL ¬MOD
¬BESSEL           // We put the name of the program with the integral in ALPHA
STO 00            // We store our current guess for X in R 00 to be accessible by the integral finction
0                 // put upper and lower limits for the integration in Y and X
PI
INTEG             // xeq INTEG from Advantage Pac
ABS               // our current guess, make it positive
X<=Y?             // Y has the Integration's estimate of accuracy - we use this to limit our search
ClX               // if our guess has returned a value from the integral that's less than the inherent accuracy then that's GOOD ENOUGH, we set X to zero and SOLVE completes     
X≠0?              // if we still don't have zero we put back the last guess and SOLVE continues

Running it

MYSOLVE sets up the ALPHA register with the name of the prog to be solved, so nothing needed in ALPHA at this time
put initial guesses in X and Y
- 1 ENTER 2
try FIX 4
Run MYSOLVE - via XEQ or set up a CST menu item for it

After a few minutes of Goose-flying we get the answer 2.4048

Useful Memo prog

MEMO

65c22 Timer values

for VIA Tone generator

Needs Ladybug module

The required count is calculated from Φ₂ and the audio frequency required.

Count (decimal)

{ Φ₂ / ( 2 x F ) } - 2

for 1000Hz and a 1MHz Φ₂ :

Count = { 1,000,000 / ( 2 X 1000 ) } - 2 = 498

498d → $01F2

Run as XEQALPHATIALPHA

Prompt F for required audio tone frequency.

Enter freq

R/S

Result is the 2-byte value for T1CL & T1CH

e.g.

XEQALPHATIALPHA

R/S

Result:

$001F2

The Counter should be set to

T1CH = $01
T1CL = $F2

Entered as follows (make sure you're in DECS mode in Ladybug while entering the program - otherwise the 1000000 won't be interpreted correctly). When viewing/editing the program later it will look different!

============= 13/2/22 ===========================


#### HP35s Butterworth Filter designer
#
# Changed 12/2/22 to make it fit in a single prog label with no
# sub routines (ie using up additional labels). Frequency entry

# 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.

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.

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!

MediaWiki VPS Install

MediaWiki VPS Install

— John Pumford-Green 27/04/23 06:21

I have recenlty rebuilt the VPS install during a hardware upgrade, and the Mediawiki install is no longer in place.

The following guide would allow it to be re-installed should I decide to.

To compare mediawiki with dokuwiki I installed mediawiki on my little shack server.

I followed the instructions here

https://www.mediawiki.org/wiki/Manual:Running_MediaWiki_on_Debian_or_Ubuntu

and did a few tweaks etc. to get things running.

I forgot to document the tweaks!

So I thought there would be no harm in installing it on my VPS to run alongside the main dokuwiki site, with a view to deciding whether to switch to mediawiki later.

Here are my steps to install mediawiki on the VPS machine, which already has a fully configured and working webserver & PHP. The main addition will be setting up a SQL server (probably MariaDB).

Installing pre-requisites

sudo apt-get install apache2 mariadb-server php php-mysql libapache2-mod-php php-xml php-mbstring

wget https://releases.wikimedia.org/mediawiki/1.38/mediawiki-1.38.1.tar.gz

tar zxvf mediawiki-1.38.1.tar.gz

sudo mkdir /var/www/html/mediawiki

sudo mv mediawiki-1.38.1/* /var/www/html/mediawiki

That has installed a SQL server and the mediawiki files into the webserver root. Next is to configure the SQL database to hold the wiki.

SQL Configuration

gm4slv@gm4slv:~$ sudo service mysql START
gm4slv@gm4slv:~$ sudo mysql -u root -p
Enter password:
Welcome TO the MariaDB monitor.  Commands END WITH ; OR \g.
Your MariaDB connection id IS 36
Server version: 10.3.34-MariaDB-0+deb10u1 Debian 10

TYPE 'help;' OR '\h' FOR help. TYPE '\c' TO clear the CURRENT INPUT statement.
 
MariaDB [(NONE)]> CREATE USER 'new_mysql_user'@'localhost' IDENTIFIED BY 'mwPass';

MariaDB [(NONE)]> quit;
Bye

Create the database and grant the user access

gm4slv@gm4slv:~$ sudo mysql -u root -p
Enter password:
Welcome TO the MariaDB monitor.  Commands END WITH ; OR \g.

MariaDB [my_wiki]> GRANT ALL ON my_wiki.* TO 'new_mysql_user'@'localhost';
Query OK, 0 ROWS affected (0.001 sec)
 
MariaDB [my_wiki]> quit;
Bye

Browse to https://gm4slv.org.uk/mediawiki and got an error message that there was a PHP component missing intl

sudo apt-get install php-intl

sudo service apache2 restart

Browse to mediawiki again and all seems well. The message now is that LocalSettings.php is missing, which is created at the next step, following the on screen link.

Configure the SQL access:

Database Username : new_mysql_user
Database Password : mwPass

Complete the questions, select the required extensions etc. and download the LocalSettings.php file. Then upload the file to the VPS and put it in /var/www/html/mediawiki

Tweaks

File uploads

Make sure images directory has ugo+rwx permissions

Logo

Somehow upload a logo.png into images and edit LocalSetting.php to point at the log:

$wgLogos = [
        '1x' => "$wgResourceBasePath/images/logo.png",
 
 
        'icon' => "$wgResourceBasePath/images/logo.png",
];

Image thumbnails & pdf

to be continued

sudo apt install ghostscript imagemagick xpdf-utils

add to LocalSettings.php:

$wgPdfProcessor = '/usr/bin/gs';
$wgPdfPostProcessor = $wgImageMagickConvertCommand; // if defined via ImageMagick
// $wgPdfPostProcessor = '/usr/bin/convert';  // if not defined via ImageMagick
$wgPdfInfo = '/usr/bin/pdfinfo';
$wgPdftoText = '/usr/bin/pdftotext';
 
 
$wgFileExtensions[] = 'pdf';

Now upload a pdf file and it should appear in the file brower.

Try putting it in a page with the <gallery> funtion

<gallery>
File:Blog.pdf|page=1

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

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.

Watchwinder

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°

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

Repairs / Mods

2023 : No Transmit Output Power.

Receive functions normally
trace to - pre-drive TX buffer amp transistor - Q1 Main PCB
- No Drive to PA from Main Board
- TX signal present at base of Q1 but no signal at collector
- Q1 2SC4673 sourced from eBay https://www.ebay.co.uk/itm/322993473692
- 07/02/23 : Replaced Q1 and full transmit power restored.

Remote Control

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.

←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.

60m

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.

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.

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?

CCIR493 Selcall - 2026

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.

QRSS

←Radio Topics

QRSS

I've started playing with QRSS, inspired by getting involved with QMX and QCX and the QRP world. QRSS is something to use the equipment for while I'm not actively operating CW, and by either transmitting QRSS for other people to receive, or running a receive “grabber” for other people to observe, I'm helping with other people's experimental use of the hobby (and my own). I could continue using WSPR for similar ends, but I find QRSS much more human.

First Step

I need to be able to receive - never transmit if you can't receive first. I remember using Spectrum Lab in the past, on 500kHz for a grabber, and I knew it ran well under Wine on Linux. So I installed Spectrum Lab on my Linux shack laptop.

A bit of fiddling and I got it to display QRSS nicely.

Grabber

Receiving locally is nice, but the real fun comes from sharing the waterfall image via the internet…. a “grabber”

That just required setting Spectrum Lab to make regular screen captures, and to deposit them in a directory where they can be accessed by the Linux system easily.

And then a small bash script to send the file by SCP to my VPS webserver.

#!/bin/bash
DIR=/home/g4slv/Screenshots
 
sleep 5
 
scp -P 2182 $DIR/capt.jpg g4slv@g4slv.info:
rm $DIR/capt.jpg

and on the VPS another bash script to rename the new capture to include a datestamp, and then to copy the new capture to the webserver, along with the date-stamped copy.

#!/bin/bash
 
 
DATE=`date +%y%m%d_%H%M`
 
DIR=/home/g4slv
sleep 30
if [ -e capt.jpg ]
then
        cp capt.jpg capt_$DATE.jpg
        sudo mv $DIR/*.jpg /var/www/html/grabs/
fi

This makes sure I don't lose all the grabs, and can access them via the website, to look for interesting artifacts, or signals of interest.

Both scripts run every 10 minutes via Crontab. Each script has a sleep command to delay its operation to allow the correct sequence of actions, and to give time for the SCP operation to upload the new capture file to the VPS.

On the following grab, at 12:00 UTC 8 Jul 2026 are:

GM4GKH using some Hell variant rather than QRSS CW
S52AB
SO5CW
G0PKT
M0BMN
G0MBN
G4JQT
IK2JET

QRSS TX

To set the QMX to operate as a QRSS beacon is a bit convoluted….

Protection
- PA Max volts → 3V - this will give approx 1W
Messages
- Message 1 → GM4SLV
Keyer (from single click of Menu key in normal operation mode) → 6 (dot = 6 seconds)
Beacon
- Mode → FSKCW
- Frequency → 10,140,050
- Frame → 10 (repeat every ten minutes)
- Start → 0 (start on minute zero)
- Time → set to any random time, it's just used to start each TX cycle every “Frame” minutes. Absolute time isn't important.

Sending “GM4SLV” at 6-second dot takes about 7 minutes, and then there's 3 minutes of RX to allow the PA to cool down, and the cycle repeats every 10 minutes. I don't know if the RTC is accurate enough to allow for “stacking” to improve reception of my signals, without GPS time lock it might drift around a little?

Direwolf update : 10/04/24

Direwolf v1.6 in Debian has a minor annoyance - it decodes its own transmitted frames occasionally due to cross talk in the sound card
This is reported to be fixed in 1.7 release so I cloned the git repository and built the current 1.7 version
It has removed the annoyance of seeing (and reporting to APRS-IS) your own transmitted packets
There are other changes and improvements which I will investigate over time.
Steps to clone/build

sudo apt-get install libavahi-client-dev
git clone https://www.github.com/wb2osz/direwolf
cd direwolf
 
mkdir build && cd build
cmake ..
make -j4

Running the new version

cd src
./direwolf -c ~/direwolf.conf

A few red warnings due to changes for v1.7 not being fully compatible with the previous config options, but it runs and doesn't seem to decode its own transmissions any more.

A few tweaks to the config:

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:

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

Svx Mobile

anonymous@undisclosed.example.com (Anonymous) — Thu, 04 Jun 2026 21:03:37 +0000

←SVXLink

Svx Mobile

Plan…

To make a mobile hotspot that will provide access to SVXReflector and Echolink as well as a handy single-frequency parrot repeater.

Hardware

Remains the same as the previous portable hotspot

Raspberry Pi
CM108 soundcard
IC-2E
MiFi router

It will be installed in my vehicle, which also has a TM-D710 for APRS and voice comms.

Add 5V regulator to power R.Pi from 12VDC
Put everything in a grab-box for portability

SVXLink Config

Echolink Module enabled (switchable via DTMF commands)
Echolink using a Java JRE and Echolink Proxy running on my VPS machine to enable incoming connections.

Logic.tcl additions for switching EL on/off

Added to <…>/events.d/local/Logic.tcl

 # Example: Custom command executed when DTMF 97 is received
  if {$cmd == "97"} {
    puts "Executing external command"
    playMsg "Core" "online"
    exec /home/gm4slv/svx_ref_el.sh &
    return 1
  }

  # Example: Custom command executed when DTMF 98 is received
  if {$cmd == "98"} {
    puts "Executing external command"
    playMsg "Core" "online"
    exec /home/gm4slv/svx_ref_noel.sh &
    return 1
  }
  # Example: Custom command executed when DTMF 99 is received
  if {$cmd == "99"} {
    puts "Executing external command"
    playMsg "Core" "online"
    exec /home/gm4slv/svx_noref_el.sh &
    return 1
  }

DTMF command 97# will cause svxlink to restart with Reflector connected, Echolink connected.
DTMF command 98# will cause svxlink to restart with Reflector connected, Echolink disabled.
DTMF command 99# will cause svxlink to restart with Reflector disabled, Echolink connected.

Start with Reflector ON and Echolink ON

97#

#!/bin/bash
 
CFG=/usr/local/etc/svxlink/svxlink_ref_el.conf
LOG=/home/gm4slv/svxlink.log
 
sudo killall svxlink
sudo killall svxlink
sudo killall svxlink
 
echo "25" > /sys/class/gpio/export
 
sleep 2
 
echo "out" > /sys/class/gpio/gpio25/direction
 
sudo svxlink --daemon --logfile=$LOG --config=$CFG
exit 0

Start with Reflector ON, Echolink Disabled

98#

#!/bin/bash
 
CFG=/usr/local/etc/svxlink/svxlink_ref_noel.conf
LOG=/home/gm4slv/svxlink.log
 
sudo killall svxlink
sudo killall svxlink
sudo killall svxlink
 
echo "25" > /sys/class/gpio/export
 
sleep 2
 
echo "out" > /sys/class/gpio/gpio25/direction
 
sudo svxlink --daemon --logfile=$LOG --config=$CFG
exit 0

Start with Reflector disabled, Echolink ON

99#

#!/bin/bash
 
CFG=/usr/local/etc/svxlink/svxlink_noref_el.conf
LOG=/home/gm4slv/svxlink.log
 
sudo killall svxlink
sudo killall svxlink
sudo killall svxlink
 
echo "25" > /sys/class/gpio/export
 
sleep 2
 
echo "out" > /sys/class/gpio/gpio25/direction
 
sudo svxlink --daemon --logfile=$LOG --config=$CFG
exit 0

It's probable that I'll configure the initial start @reboot to be with Reflector and Echolink

crontab → @reboot sleep 30 && sudo -u gm4slv /home/gm4slv/svx_ref_el.sh >/dev/null 2>&1

Using a PROXY server for connecting to Echolink, and be able to accept incoming Echolink connections, is necessary because it's not possible to control external firewall/port forwarding when using the MiFi 4G router for internet access.

Connecting direct to Echolink, without the proxy still allows outgoing Echolink connections to be made

Rather than relying on other PUBLIC Echolink proxies I though it would be wise to install and run a proxy server myself, on the VPS machine. It turned out to be easier than I thought and the basic steps are here

Parrot

I imagine being able to use the Parrot feature as a temporary single-frequency repeater perhaps for emergency use?

I'll experiment….

Yaddnet Migration

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

←YaDDNet

Yaddnet Migration

My http://www.yaddnet.org DSC database originally ran on various machines in my shack at home. It was migrated to a server donated for the purpose - located in Las Vegas, in 2019. This document records the steps needed to transfer everything and get it running on the new Virtual Private Server. In case it ever needs doing again in future this will help jog my memory of what's involved.

Moving YaddNet to a Virtual Server in the Clouds

Created Thursday 24 October 2019

Server IP: 64.235.39.127

Create SQL database

UPDATE 13/04/24

MIGRATING TO A NEW UBUNTU 20.4 VPS REQUIRED THE FOLLOWING

https://ostechnix.com/how-to-reset-root-password-in-mysql-8-on-ubuntu-linux/

The original Process

1) sort out passwordless root access to MySQL

add skip-grant-tables to end of config file:

(such as….)

/etc/mysql/mysql.conf.d/mysqld.cnf

restart mysqld

$ mysql -u root
mysql>FLUSH PRIVILEGES;
mysql>ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY '';
mysql>quit;

remove skip-grant-tables from /etc/mysql/mysql.conf.d/mysqld.cnf

restart mysqld

2) create blank/empty yadd database

$ mysql -u root

mysql> create database yadd;
mysql> quit;

2a) scp migrate tarfile to remote server

and wait….

2b) untar migrate tarfile

3) use saved schema file to create the tables:

$ mysql -u root yadd < schema.sql

4) import the full database backup:

$ mysql -u root yadd < yadd_xxxxx.sql

and wait……. and wait……

5) test all the data is there…!

Create Web site

6) extract yaddnet files from tarball

7) extract html files into /var/www/

8) permissions/ownership of /var/www/html ? Not Needed

9) apache “sites-enabled” - change virtual server's port? Not needed

Configure auto-start of Input servers

10) /etc/rc.local command to start tmux session

sleep 60; su USER -c /home/USER/yaddnet/tmux_yadd.sh &

11) start tmux session and see if it's working…

12) fire some test packets at it from uCoastTester.py

13) crontab entries

15 */4 * * * /home/USER/yaddnet/purge_err.sh > /dev/null 
* * * * * /home/USER/yaddnet/purge_tmp.sh > /dev/null

Tweaks

14) Character encoding for pages

edit /etc/php/7.2/apache2/php.ini

change default_charset from UTF-8 to ISO-8859-1:

default_charset = "ISO-8859-1"

This renders “degree” signs etc. on web pages correctly.

15) mysql config

add to /etc/mysql/mysql.conf.d/mysqld.conf

sql_mode = "STRICT_TRANS_TABLES,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION"

restart mysql

This (among other things) allows the group-by queries to work.

16) Open firewalld UDP port 4530 for DSCDecoder (and close unneeded port 9999)

firewall-cmd --permanent --service=yadd --add-port=4530/udp

firewall-cmd --permanent --service=yadd --remove-port=9999/udp

firewall-cmd --complete-reload

Firewall Config - note 21/5/22

While creating this Wiki page, from a previous note in ZimWiki, I wondered about the firewall config, as it appears I didn't explicitly open UDP/50666 for YaDD's traffic, but I added udp/4530 for DSCDecoder.

Looking at /etc/firewalld/services/yadd.xml I see:

<?xml version="1.0" encoding="utf-8"?>
<service>
  <short>yadd</short>
  <description>YaDD Service</description>
  <port port="50666" protocol="udp"/>
  <port port="4530" protocol="udp"/>
</service>

so 50666 must have been added when the VPS was built (not my me). I guess I asked for it when the offer to provide the VPS was made, but forgot about DSCDecoder until later.

Get Domain Name

16) Buy domain yaddnet.org from “fasthosts.co.uk” and set DNS record to point host www.yaddnet.org to the new server IP address

£10.79 per year, auto-renew via PayPal.

UPDATE 18/11/19

Received an email from kb7ypf@yahoo.com:

“I have been using yaDD 1.7.1 monitoring and logging GMDSS signals. I have been using it for about two weeks. This morning when I started yaDD it worked great, as usual, however, when I went to the web and accessed the message logging page, I got this message: “Failed to connect to MySQL: Access denied for user 'root'@localhost' …….”

Unattended-Upgrade breaks MySQL

I confirmed the same symptoms…

but it was working this morning?!

SSH'd into the server and couldn't access mysql from the commandline, either, same error.

This reminded me of the behaviour of a “stock” mysql server before doing the steps in 1) above.

Found an entry in /var/log/apt/history.log from 06:25 PST (14:25 UTC)

Start-Date: 2019-11-18  06:25:08
Commandline: /usr/bin/unattended-upgrade
Upgrade: mysql-server-5.7:amd64 (5.7.27-0ubuntu0.18.04.1, 5.7.28-0ubuntu0.18.04.4), mysql-server-core-5.7:amd64 (5.7.27-0ubuntu0.18.04.1, 5.7.28-0ubuntu0.18.04.4)
End-Date: 2019-11-18  06:25:29

Looks like “unattended-upgrade” has upgraded mysql, and also reset the normal permissions/privileges. Bloody Hell!

stop mysql
edit mysqld.cnf to add “skip-grant-tables”
start mysql
log in to mysql “mysql -u root”

$ mysql -u root
mysql>FLUSH PRIVILEGES;
mysql>ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY '';
mysql>quit;

stop mysql
remove “skip-grant-tables” from mysqd.cnf
start mysql
test…

looks like we lost about 1 hour of DSC loggings while the SQL server refused to talk to us, from 14:25 UTC until ~15:30 UTC when I got it running normally again.

…..and relax!

going forward

Have 2 choices - remove unattended-upgrades package and lose all automatic security upgrades OR configure unattended-upgrades to blacklist mysql-server from upgrades.

https://wiki.debian.org/UnattendedUpgrades and https://help.ubuntu.com/community/AutomaticSecurityUpdates

has some helpful info… found where to blacklist individual packages….

service unattended-upgrades stop

edit /etc/apt/apt.conf.d/50unattended-upgrades to blacklist mysql

	// List of packages to not update (regexp are supported)
	Unattended-Upgrade::Package-Blacklist {
			"mysql-server";
			"mysql-server-5.7";
			"mysql-server-core-5.7";
	};

service unattended-upgrades start

check it's running:

gm4slv@lasvegas-nv-datacenter:~$ apt-config dump APT::Periodic::Unattended-Upgrade

APT::Periodic::Unattended-Upgrade "1";

hopefully that will sort it?

YaDDNet : New VPS

anonymous@undisclosed.example.com (Anonymous) — Fri, 05 Jun 2026 07:43:18 +0000

←YaDDNet

YaDDNet : New VPS

Moving YaDDNet from USA to UK

Background

YaDDNet started hosted on a machine in my shed
In 2019 I almost gave up maintaining & hosting it and was approached by Alan Spindel ex. of WLO/Mobile Radio with the offer of a free VPS in the States
I moved everything from my own PC to the new Cloud Server - as documented largely here Yaddnet Migration
It's run quietly and without too may hiccups since 2019 until now, April 13th 2024
Alan has now been asked to contribute financially for continued access to the VPS - up to $200 per month
This is way too much money!
I looked at my current VPS hosted by Fasthosts and they do a VPS with similar specs to the existing USA-based server - for £12 per month
I let Alan know I'd take on the new server and migrate YaDDNet ASAP, and began the process of obtaining server, installing software required, copying YaDDNet Python code, transferring YaDDNet HTML/PHP web pages and then the big job of taking a MYSQL dump of the YaDDNet database and copying it over, and putting it into the new SQL server.
Let the fun begin

New VPS

I bought a VPS L from Fasthosts
- 120GB HDD, 4GB RAM, 2 CPU, Ubuntu 20.4
I copied the yaddnet python code (in a tar-ball) that deals with the network feeds of Yadd and DSCDecoder and injects the resulting data into the MySQLdatabase from the existing server.
I installed the necessary software
- Python2.7
- python-is-python2
- python-dev-is-python2
- MySQL Client
- MySQL Server
- Apache2
- PHP
- Tmux
- Vim
- copied my .bashrc from the old server for colour prompt etc.

Using the previous Yaddnet Migration info Yaddnet Migration I had some guidance of any tweaks needed.
I needed extra Python2 supporting libraries
- For MySQLdb → pip install MySQL-python
- but for pip…. I need pip2… how to get it - it's no longer available from Ubuntu's apt repositories.
  - I found a script get-pip.py at github
    - https://github.com/pypa/get-pip
    - also need python-dev from apt
    - also need my_config.h from where..?
    - finally can pip install MySQL-python

curl https://bootstrap.pypa.io/pip/2.7/get-pip.py --output get-pip.py
sudo python2 get-pip.py
sudo apt-get install python-dev
sudo wget https://raw.githubusercontent.com/paulfitz/mysql-connector-c/master/include/my_config.h -O /usr/include/mysql/my_config.h
sudo pip2 install MySQL-python

at this point I could run the python server code, in a tmux session as usual, using the shell script in the python directory extracted from the tar-ball. All the supporting libraries were there.

MySQL config

My old notes had instructions of how to set MySQL for password-less root access, but I found by trial and error that these steps no longer work in Ubuntu 20.4, with systemd
I found some help online https://ostechnix.com/how-to-reset-root-password-in-mysql-8-on-ubuntu-linux/
- the basic is that it's now necessary to add options to MySQL via systemd
- for skip-grant-tables

$ sudo systemctl stop mysql
$ sudo systemctl status mysql
$ sudo systemctl edit mysql

[Service]
ExecStart=
ExecStart=/usr/sbin/mysqld --skip-grant-tables --skip-networking

$ sudo systemctl daemon-reload
$ sudo systemctl start mysql
$ sudo mysql -u root

mysql> FLUSH PRIVILEGES;
mysql> ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY '';
mysql> exit

$ sudo systemctl revert mysql
$ sudo systemctl daemon-reload
$ sudo systemctl restart mysql

Make database for yadd

$mysql -u root

mysql> create database yadd;
mysql> quit;

Get the data

on the old server

$ mysqldump -u root yadd > yadd_backup.sql

and wait…. and wait…..
eventually there's a 6.2GB sql file containing all the existing data
bzip2 the file to make it smaller (it's about 400MB now) for scp transfer to the new server
send it across:
- scp yaddnet_backup.sql.bz2 gm4slv@109.228.53.165:

on the new server
- bunzip2 yaddnet_backup.sql.bz2
- and wait….and wait
then inject it into the new yadd database

mysql -u root yadd < yaddnet_backup.sql

and wait…. and wait…. and wait
eventually the command returns and the database is restored on the new machine

Web pages

extract the backed-up webpages from the old server and copy them to /var/www/html
To be able to retrieve SQL data via PHP I needed to install more

sudo apt-get install php-mysql

Almost there….
New MYSQL user with a password for PHP data retrieval
- Alan Spindel informed me that there was an update some time ago and it was necessary to create a new MySQL user, with a password, and to modify the PHP files to use it in the PHP → MySQL transactions

CREATE USER 'XXXXX'@'localhost' IDENTIFIED WITH mysql_native_password BY 'YYYYY';
GRANT ALL PRIVILEGES ON *.* TO 'XXXXX'@'localhost' WITH GRANT OPTION;

XXXXX is the username as set in all the PHP files and YYYYY is the password for the user
to perform some of the SQL queries (group-by) - need to alter sql-mode but again the old method using *.cnf files no longer works

# MySQL systemd service file

[Unit]
Description=MySQL Community Server

set up my own Yadd receiver pointing at 109.228.53.165 port 50666 and let it send new data….
it's arriving!
Alter DNS for the domain at Fasthosts to point yaddnet.org and www.yaddnet.org → 109.228.53.165
Wait for new data from other YaDD receivers to start arriving as the DNS change propagates….
it's arriving
make /var/www/html/pages/php/test/tmp world read/writable to allow new text files to be written there (eg REU searches etc.)

Clean up

that's everything working correctly
crontab entries to maintain everything

@reboot sleep 60; sudo -u gm4slv /home/gm4slv/yaddnet/tmux_yadd.sh >/dev/null 2>&1
 
 
15 */4 * * * /home/gm4slv/yaddnet/purge_err.sh > /dev/null

get SSL certificates from Fasthost and convert Apache2 to HTTPS, per previous posts
- SSL Install on VPS

install mercurial on new server and make new code repositories

hg init
hg add
hg com -m "first commit, new server"

yaddnet_repo containing the python and various bash scripts for handling incoming data and SQL injection
yaddnet_web_repo containing the html and php web pages

Extra

config directory needs access control via .htaccess and .htpasswd
- first apache2 needs config tweaking

<Directory /path/to/website/database_tweaks/config>
        Options Indexes FollowSymLinks
        AllowOverride All
        Require all granted
</Directory>

.htaccess file in config directory

AuthType Basic
AuthName "Password Protected Area"
AuthUserFile  /path/to/website/database_tweaks/config/.htpasswd
Require valid-user

create a .htpasswd file for the user who can have access to config
restart apache2
to prevent directory file-listing (where there's no index.html file) remove Indexes from apache2.conf

<Directory /var/www/>
        Options  FollowSymLinks
        AllowOverride None
        Require all granted
</Directory>

to allow the test directory itself to be listed (I can't be bothered to maintain an index for these scraps of php)

<Directory /var/www/html/pages/php/test/>
        Options Indexes FollowSymLinks
        AllowOverride None
        Require all granted
</Directory>

restart apache2
