DM15L Progs

Dumps taken from the DM15L using a serial console session in Putty.

Stock Swiss Micros Firmware

Dumps are also converted to readable program listings using the Swiss Micros online encode/decode tool at https://technical.swissmicros.com/decoders/nut/

Normal + "Complex Z to....."

LBL E converts Z=R±jX to RL, SWR, |ρ|∠ρ, |Z|∠Z

Data input :

if Z = R + j X, put R in Y-stack and X in X-stack and then run LBL E

R ENTER
X (and CHS as needed)
F
E

Results appear:

Stack X → Return Loss
Stack Y → SWR
Stack Z → (Re) |ρ| (Im) ∠ρ
Stack T → (Re) |Z| (Im) ∠Z

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

←3rd Party Firmware

LF15C - firmware for the DM15

A 3rd Party Firmware for the DM15 family of calculators

Overview of LF15C

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

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

Installing LF15C

DM15L running V32 or earlier (Linux)

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

DM15L running V33 or later (Linux)

This behaviour isn't consistent!

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

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

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

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

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

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

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

For installation using Windows

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

-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.

Anytone Smart CB for 10M

Small 11m/10m AM/FM mobile

Bought May 2023 from http://www.4x4cb.com/index.cfm - very helpful and friendly CB dealership - well recommended
User Guide : smart.pdf
User Guide : manual_anytone_smart_i_eng_cb.pdf

Modification

Modification to “Export Model” to provide 10m (and 12m) amateur bands and the 11m CB channels
Solder 2 jumper pads as per photo:

Resulting 14 bands can be selected:
- Power-on while holding A/F and cycling through with Mic UP and DN buttons
- Once selected : Power Off, Power On. Display briefly shows active band

Band	Channel 1	Channel 40	Comments
A	25.615	26.055	SS Low
B	26.065	26.505	S Low
C	26.515	26.955	Low
D	26.965	27.405	Mid / CEPT EU
E	27.415	27.855	High
F	27.865	28.305	S High / 10m
G	28.315	28.755	10m
H	28.765	29.205	10m
I	29.215	29.655	10m (29.600 = CH35 R)
J	29.665	30.105	10m +
†	25.165	25.605
L	24.715	25.155
N	24.890	24.990	21 Channels 12m Ham
U†	27.60125	27.99125	UK CB

All channels (except in Band N/12m) end in 5kHz. To drop to -5kHz (end in 0kHz) press/hold RFG. R is displayed.
- For 10m FM on Band I 29.600 is Channel 35 R
The bands follow the usual CB pattern, with 10kHz jumps, Alpha Channels, after 3, 7, 11, 15, 19. The Smart CB includes these as 3A, 7A, 11A, 15A and 19A.
All bands (except Band N 12m which only has 21 channels, and the UK CB band) follow the CB channel protocol of out of sequence channels 22, 23, 24, 25, 26 thus
- Band I (10m FM) with -5kHz R activated
  - Channel 22R : 29.470
  - Channel 23R : 29.500
  - Channel 24R : 29.480
  - Channel 25R : 29.490
  - Channel 26R : 29.510
- The Channels, in frequency order : …22,24,25,23,26…
To select Output Power:
- Press/hold RFG, PTT and Power On
  - Use Mic UP and DN to cycle through 3 power levels:
    - PL = 4W
    - Pn = 8W
    - PH = 15W
  - Once selected : Power Off, Power On
  - 15W might be overdoing it - in such a small package with limited heatsinking. 8W is probably the best option.

10m Channels

Assume R -5kHz is active

Also check with R inactive (freq. ends with 5kHz)

←Damasko DA36

Damasko DA36 Tests 1 (2019)

Created Thursday 31 October 2019

Investigation into fault last seen Aug 2018

Fault symptoms from 30/8/18

rate error high (> 30s/d) and dependant on position
amplitude low ≤200°
hand-winding would not increase amplitude or improve random fluctuating rate.

Investigation to confirm fault prior to arranging repair : 30/10/19

wind 40 turns manually & set time: Δ = -0.7s
on wrist 19:00
take TG measurements as auto power builds up over evening

Conclusion

There seems to be nothing wrong.

4 full days of on-wrist testing shows normal amplitude and rate error.

Power-run-down test gives a reserve time of ≥33 hours. This is less than the ETA 2836-2 spec of 38 hours. This may be due to starting the test with less than full wind? 33 hours is still acceptable. Rate and amplitude drops after 24 hours, but accumulated error is still acceptable if the test had been stopped before completion and the watch worn (an additional ~5 seconds of loss over the 33 hours of testing).

Restarting and achieving full-power/amplitude & normal rate error takes some time on-wrist - avoiding manually winding as far as possible, just enough to start the movement running. Is there still an intermittent problem with the winding or power?

Time will tell.

RTC Correction

approx. error +3.5s/d = +40.5ppm
Correction factor C from C = 2^20 P /(10^6 + P)
Approximations :
- C = 1.04858 P
- P = 0.953674 C
Calculated C = -42.47

Put a text file /rtccalib.cfg in root directory of FAT drive with contents:

-42.47

Update 28/5/22

After a period of observation the rate is now over-corrected. Try reducing correction to -37.5 which corresponds to a ppm error of 35.76ppm, or 3.26 s/d.

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

41Z Deluxe Module

Weird behaviour with its "common factor" display

Update September 2024

The factorization error in the deluxe version has been fixed by Angel….

I see this watch as a modern version of Rolex's Milgauss - tough with the same level of Magnetic Resistance as the original Milgauss (1000 Gauss). The original anti-magnetic engineer's watch from Rolex wasn't the multi-thousands-of-pounds bauble they sell today.

Originally Rolex produced relatively expensive, but still affordable, tool-watches.

Unlike the Veblen Goods they churn out today.

Damasko's original and iconic watch, the DA36, is something akin to an early Rolex. Not cheap, but also not ridiculously over-priced. It has no obvious external frills, but has plenty of technology inside to justify the price and to add functional value.

I often ponder whether I'd buy a Milgauss if I could afford the £7000+ price tag. And now I've lived with the DA36 for almost 6 years I don't know that I would. My watch is now my watch. Why swap for another expensive toy?

Damasko have recently re-configured their range of watches and dropped the DA36, and most of the others from their early years of production, as they move upwards, into making higher price watches with in-house movements, rather than using off-the-shelf ETA units.

I'd love a DA36 to appear with the in-house movement, but I don't know that this is going to happen.

UPDATE — John Pumford-Green 24/04/23 17:45

The DA36 has now reappeared - as the DK36 with the new in-house A26-3 movement.

DK36 at Damasko

My watch developed a fault after a couple of years but this was easily repaired by Damasko. I might have introduced the fault myself after opening it up a few times to regulate it - perhaps I let in some dirt that found its way to the escapement and caused some abrasion?

I don't know.

It's now working perfectly well after 2½ years of continuous daily wear. I only take it off to have a bath/shower and (usually) to sleep, and very rarely if I need to squeeze my left hand into a tight space when working on cars, Land Rovers or transmitters. I don't think I've let it run down since the repair in December 2019.

The Milgauss

A modern Milgauss for comparison. There's not a lot of aesthetic similarity, the modern Milgauss is quite gaudy, with its green sapphire crystal and shiny dial.

The 1960's version ref. 1019 (not the original submariner style with a timing bezel) looks more workmanlike and is the one I'd go for if I had the money. When I last looked a birth year 1966 Milgauss fetches around £22,000…. so I'll stick with my DA36 and let it age with me.

The Damasko Steel Bracelet

The DA36 was bought with the Damasko steel bracelet and initially I was happy with it.

It is super-engineered. Each link, of ice hardened bead-blasted steel to match the watch's case, is fixed with strong torx secured pivot pins. The whole bracelet can be dismantled for cleaning. It's very strong, very well designed and very well made.

After time though the lack of adjustment (even with the two supplied “long” links) meant it became difficult to find a good comfortable fit.

The DA36 was then worn mostly on the Damasko leather strap or a variety of NATO straps, including some elastic MN types, which are certainly very comfortable.

The steel bracelet was sold in 2017, to someone in the USA, after I decided I couldn't get on with it.

Following the appearance of the rate-error fault in 2018, I switched to my Seiko SKX007 on a Strapcode Oyster steel bracelet, and liked it so much I decided to buy another Damasko steel bracelet for the DA36, and to request a set of additional adjustment links to allow more variation in size. The longer links can be bought in sets of 2 pairs, which along with the 2 pairs that come with the bracelet, allow a smooth adjustment in tiny steps, almost matching the difference made by adding or removing a normal link.

The new bracelet and links were bought in November 2019.

This allowed the use of up to 5 ¹⁾ adjustment links to step smoothly between the jump in one normal link. A good fit was obtained with 3 or 4 added long links. After some time I found I could wear the bracelet with no adjustment links, my wrist settled to a size that suited a whole number of normal links, but I have the option of a good range of adjustment, if things should change in future.

I occasionally put a NATO strap on, but it rarely stays for more than a day or two before the pull of the super-strong super-engineered bracelet wins out.

Update May 2022

I've owned the DA36 now for over 5 years. After the repair, and getting the 2^nd bracelet, it's rarely off my wrist. I'll occasionally wear another watch (typically a Casio GW-M5610) on my right wrist.

The DA36 stays on the left.

The ice-hardened steel is very resistant to scratching or other marks. After 5 years I can see some slight blemishes - just signs of an active life. The bracelet has more marks than the watch case itself - links rub against each other and the bracelet is more likely to be rubbed against hard surfaces than the watch - and as time goes by it slowly (very slowly) starts to look less like a new watch and more like a tool watch.

There are marks on the bezel, and on the bracelet end-link, at the 12 o'clock position, I guess I caught it on something abrasive at some time…. more wabi-sabi

The hardened steel, and matte bead-blasted finish, mean that there is no slow development of a general swirly patina. A scratch shows up, in the right light, as a shiny area of un-bead-blasted reflective steel. It's just the characteristic of the material. I wonder what it'll look like in another 10 years?

Time Keeping performance

Still well within COSC standards ( -4 / +6 ) at around -2s/d as of May 2022. Rolex now guarantee their watches to run better than COSC, at ±2 s/d. My DA36 has been within this range for the last few years, and is only now starting to fall outside that range. It may wander back towards zero over time. Who knows how all the different variables inter-react to make up the overall rate error, and how they vary with time?

Yaddnet Migration

←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?

For multiple loops store a Loop Count in C (or in Register 03)

(1000 STO C) and then XEQ C

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

Damasko DA36 Repair (2019)

Created Monday 18 November 2019

15/11/19

Sent an email asking for advice on having the watch repaired on 15/11/19 :

Good morning,

I bought a DA36 in October 2016, direct from Damasko and I have been very pleased with it and it has been very reliable, keeping good time over the last 3 years.

The serial number is DA36.1981

Recently I have noticed that it randomly loses a up to one minute in a single day, when most of the time it keeps to within ± 2 seconds per day.

On these occasions I have observed the watch using a Timegrapher machine, and I see that the displayed rate can be as low as -240 s/d and the displayed amplitude can be as low as 126 degrees. These periods of poor performance occur randomly and do not appear to be related to any physical activity etc. Often the watch returns to normal behaviour after a few hours. I now feel that I cannot rely on the watch to be reliable in normal use.

Can I arrange for the watch to be repaired or serviced to return it to it's previous excellent and reliable performance?

Since I bought the watch direct from Damasko I am happy to return it to yourselves for the repair.

Please advise me on how to proceed.

Best wishes,

John Pumford-Green

The DA36 arrived at Damasko's Barbing factory yesterday (Fri 22nd).

Email from Isabella:

Dear Mr Pumford-Green

Today we have received your DAMASKO DA36.1981.

It will be checked by our watchmaker now. After we have a feedback we will inform you about necessary repairs.

Please note: If your watch is not under warranty and/or you decide not to carry out the repair, we have to charge you €25.21 net for the expenses incurred.

Bitte beachten Sie: Falls Ihre Uhr nicht unter Gewährleistung fällt und / oder Sie die Reparatur nicht durchführen lassen sollten, behalten wir uns vor, für den entstandenen Aufwand €25.21 netto zu berechnen.

Mit freundlichen Grüßen / Best regards

Isabella Morell

Now to await the verdict….

Update 2/12/19

Email from Isabella:

Dear Mr Pumford-Green

Thank you for sending us your DAMASKO DA36.1981.

After checking it our watchmaker told us that there is many abrasion in the movement.

In the following I may offer you the following cost estimate:

Cleaning, and oiling the escapement

Regulate DA36.1981 €120

Shipping costs UK €50

Total amount €170

The named prices are without VAT.

Please let me know, if we can go ahead with your watch.

Reply from me:

Hello Isabella,

Thank you for the information.

I would be very happy for the repair to go ahead.

I can pay in advance by PayPal or would you prefer to complete the repair before payment, in case of additional expenses that might be necessary?

Regards,

John

Reply from Isabella:

Thank you for your quick reply.

I would send you the invoice for payment by PayPal when I get the watch back by our watchmaker. May I know which invoice and delivery address I can use?

Now to wait for the repair to be complete.

What is “many abrasion” in the escapement - did I do it while regulating - introducing some foreign bodies, dirt/dust? Will not do any further regulation once I get it back, and just have it serviced every few years…. I can put up with a few seconds/day here and there, as long as it's not > ± 10s/d

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

DESCRIPTION="You have connected to a SvxLink node,\n"

/usr/local/share/svxlink/events.d/local

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
  }
  # Example: Custom command executed when DTMF 99 is received

    exec /home/gm4slv/svx_el.sh &
    return 1

exit 0

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
- remove port forwards on home router for UDP/5198 & UDP/5199
- open port TPC/8100 for only my home IP address on VPS
  - this means only one IP address can reach the Proxy on port TCP/8100
- open ports UDP/5198 & UDP/5199 for anywhere on VPS
- edit echolink proxy config on VPS to allow only GM4SLV-L to connect
  - this means only one callsign can connect to the proxy
- start proxy in a tmux session, using bash script on VPS
- edit ModuleEchoLink.conf on svxlink pi to use the proxy
- restart svx_el.sh

Brandmeister Details

On arrival (25/3/24) the Dual-Hat board had the wrong firmware (MMDVM_HS_HAT) and would not operate correctly as a duplex/two-timeslot hotspot.
Pi-Star has capability to upgrade attached MMDVM firmware, but attempts to load MMDVM_HS_Dual_Hat repeatedly failed
The firmware upload function was locked but unlocking was a simple matter of solder-bridging the pads of “JP1” on the MMDVM board.
Pi-Star Firmware upgraded successfully to MMDVM_HS_Dual_Hat v1.6 and duplex/two timeslot functionality was successful

Netradio Control

Python code for TCP/IP control of multiple radios

Server

This provides TCP/IP access to one or more radios, allowing control of Frequency, Mode, Pre-amp and Attenuator. It also gives remote access to S-meter readings.

There are separate rig-dependant command modules that then provide a standard interface for commands sent by a client, regardless of the particular radio connected.

There are modules for

Icom C-IV radios such as IC-R75, IC-718, IC-7200 etc.
AOR AR7030
Icom IC-M710 marine

GM4SLV Allstar 2025

New explorations into Allstar and Bridging

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

Hardware

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

DVSwitch Bridging

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

Instructions here: ASL to DMR Bridge

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

My configs

/etc/asterisk/rpt.conf before bridging added

; Radio Repeater configuration file (for use with app_rpt)
; Your Repeater
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
;
; This is where you define your nodes which can be connected to.
;
 
[nodes]
; Note, if you are using automatic update for allstar link nodes,

#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.

  - Normal 300 baud AFSK resolves at 2000Hz - and is decoded by WinRPR at this offset

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:

I will remove the Debian version 1.6 and sudo make install the newly compiled v1.7 once I'm happy with it.

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 : VPS SSL Renewal

←YaDDNet

YaDDNet : VPS SSL Renewal

Renewed SSL certificates for 2025/6

Read the final part about combining the 2 intermediate certificates!

15/03/25 : SSL certificates

Renewed SSL certificates available for download on Fasthosts account
- Download “Certificate” and rename → signed.crt
- Download both “Intermediate Certificates”
  - not sure why there are 2 intermediate certificates
  - rename one as ca.pem.1
  - renmame other as ca.pem.2
Use WinSCP to copy the 3 certificates to the Yaddnet VPS
Log on to yaddnet vps via SSH
- copy existing certificates in /usr/local/ssl from
  - signed.crt → signed.crt.old
  - ca.pem → ca.pem.old
- copy new certificates from home directory to /usr/local/ssl
- for clarity this gives new files
  - /usr/local/ssl/signed.crt
  - /usr/local/ssl/ca.pem.1
  - /usr/local/ssl/ca.pem.2
  - copy ca.pem.2 → ca.pem
- Restart Apache
  - service apache2 restart
- browse to https://www.yaddnet.org/index.php?
- site loads correctly
  - check site security

swap ca.pem files (copy ca.pem.1 → ca.pem)
Restart Apache
browse to https://www.yaddnet.org/index.php?
site loads correctly
security also valid

Different intermediate CA.pem certificates

I used openssl to inspect the two different intermediate certificates

gm4slv@yaddnet2:~ $ openssl x509 -in ca.pem -noout -text > /home/gm4slv/capemold.txt

for ca.pem.1

Certificate:

        Subject: C = GB, ST = Greater Manchester, L = Salford, O = Sectigo Limited, CN = Sectigo RSA Domain Validation Secure Server CA

and for completeness the old original ca.pem from prior to the renewal

Certificate:
    Data:
        Version: 3 (0x2)
        Serial Number:
            0d:e0:ff:b5:ee:62:cb:61:10:9f:60:8c:9c:ed:5e:d3

        Subject: C = US, O = DigiCert Inc, OU = www.digicert.com, CN = Encryption Everywhere DV TLS CA - G2

It appears that the certificate (ca.pem.2) from “Sectigo” has the longest validity, and that this is the more recent/appropriate one, so I've made it the certificate in use

sudo cp ca.pem.2 ca.pem

sudo service apache2 restart

UPDATE ON TWO INTERMEDIATE CERTIFICATES 5/7/25

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

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

Don't rename the 2 files as ca.pem.1 and ca.pem.2 per the above

Transfer them both with their original names and then cat them together

[root@yaddnet2:/home/g4slv/ssl]# cat 397A66CC2756362E0DAA87CA6EABE3B1.cer 7D5B5126B476BA11DB74160BBC530DA7.cer > ca.pem
 
[root@yaddnet2:/home/g4slv/ssl]# cp ca.pem /usr/local/ssl
 
[root@yaddnet2:/home/g4slv/ssl]# systemctl restart apache2

DM41X PPC ROM Curve Fit

anonymous@undisclosed.example.com (Anonymous) — Sun, 19 Apr 2026 20:12:08 +0000

←Hints & Tips

DM41X PPC ROM Curve Fit

The PPC ROM's CV function does similar Curve Fitting to the Advantage Pac CFIT program, without the limitation on negative data point values.

Negative X values are acceptable for Linear and Exponential curves

Negative Y values are acceptable for Linear and Logarithmic

If any data point has BOTH X and Y negative then only Linear is possible.

Running CV

XEQ ALPHACVALPHA

Unlike CFIT there is no displayed menu for the top-row buttons, so you need to remember the functions.

Key	A	B	C	D	E
Shift	∑-				Initialize
	Σ+	Solve Type J	Y	X	Solve Best Type

Unlike normal Stats entry (where Y-value is entered first, then ENTER, then X-value is entered second, so that the X-value is in the X register before pressing ∑+) here we enter in “conventional” order.

Clear old data SHIFT E (Initialize)
X ENTER Y Σ+
X ENTER Y Σ+
X ENTER Y Σ+
X ENTER Y Σ+
etc…..

once the data is accumulated either

enter a fit-type digit (J)
- 1 : Linear : Y = b*X + a
- 2 : Exponential : Y = a*e^bX
- 3 : Logarithmic : Y = b*Ln(X) + a
- 4 : Power : Y = a*X^b
then press B to Solve Type J

press E to Solve Best Type

The solution appears as

Z : r correlation coefficient Y : a coefficient X : b coefficient

You can now get estimates of Y (for a given X) or X (for a given Y)

You can accumulate more data (to add to what's already there) and do another FIT calculation.

If you want equally spaced X coordinates for single variable Y-data CV puts incrementing digit in X so you simply

ENTER Y₁ Σ+

ENTER Y₂ Σ+

ENTER Y₃ Σ+

ENTER Y₄ Σ+

…

and you accumulate as if you'd entered (1,Y₁), (2,Y₂), (3,Y₃), (4,Y₄)…

If you have X and Y data then the automatically incrementing X is overwritten by the manually entered real X values.

Examples

Description

Return Loss & SWR from Complex Impedance

Input Rs and Xs to calculate |z|, |ρ|, VSWR and R.Loss

Complex numbers in DM32

The DM32/HP31Sii handles complex numbers by treating stack-X as Real, stack-Y and Imaginary for one complex number, and stack-Z as Real and stack-T as Imaginary for a second complex number.

This means the normal 4 level stack can hold 2 complex numbers. This is similar to the HP41 Advantage Pack's method.

To store a complex number in a register actually requires two to be used - one for Real part and one for Imaginary part. This is similar to the HP15C/DM15L.

Once the real and imaginary values are on the stack various “Complex” functions are accessed by SHIFTCMPLXFunction for example to add

Z₁ = (10 + j20)

and

Z₂ = (30 - j25)

gives

Z₃ = Z₁ + Z₂ = ( 10 + j20 ) + ( 30 - j25 )

20 ENTER 10 ENTER
25 CHS ENTER 30

The stack will show

Then carry out the addition

SHIFT CMPLX +

The display will show

X has the real part of Z₃ (40) and Y has the imaginary part of Z₃ (-5)

Z₃ = ( 40 - j5 )

The program

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

Dokuwiki Security

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

LocationMatch method

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

add to /etc/apache2/apache2.conf

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

sudo service apache2 restart

.htaccess method

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

AllowOverride All

add to /etc/apache2/apache2.conf

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

sudo service apache2 restart

SSH Security

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

06/04/25 : Renew SSL certificate

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

UPDATE ON TWO INTERMEDIATE CERTIFICATES 05/07/25

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

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

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

Second : configure Apache to use HTTPS

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

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

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

Confirm proper security

Browse to https://gm4slv.org.uk

20/04/23 Renew SSL Certificate

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

Hardware Upgrade 20/4/23

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

Debian Upgrade 15/2/24

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

SSB TX EQ

I'm not naturally a 'phone operator and avoid playing with audio settings as much as possible. I prefer simple “communications quality” audio when I use SSB. As the FT-891 is intended to be my “phone mode radio” and I've done some initial adjustments to try and achieve a clean, basic communications-quality setup.

From what I can work out, the “bandwidth” settings of the EQ refer to Q - the smaller the number the lower the Q and the wider the affected bandwidth. I'm aiming for gentle shaping of the voice band to cut the low-end boomy bass and lift the high end “articulation” so I've set a low-Q on each pole of the EQ filter. I've set both the non-Compression and the Compression EQ settings to the same values - I want the audio to sound the same with and without the processor. The Mic's rear “tone” switch can be used to give a slight increase in low frequencies by switching → 1 if I ever feel the need.

Here are the settings I've got on the FT-891

MH31 Fist Mic rear switch → 2

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.

Set up audio levels MB7AZE SvxLink Config

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

Diaries

Diaries

I write this in the hope that anyone reading it might be inspired to start diary writing if they don't already or to continue, and to discuss their process, if they do.

I like to store memories on paper, for later. Mundane daily life or exciting events….

What is a diary as a rule?

A document useful to the person who keeps it.

Dull to the contemporary who reads it…

…and invaluable to the student, centuries afterwards, who treasures it.

Walter Scott

I keep a diary

I started in 1992, my mid-20's but then I let it lapse after a few inconsistent years of intermittent diary writing. Looking back the snatches of life I recorded from those days are (to me) fascinating and I regret not having kept it up.

I started bullet journaling in 2016, a few days before my 50^th birthday.

After about a year of this small A6 format *bullet-points-with-longer-bits-and sketches-every-now-and-again* I started *proper* daily diary writing later in 2017. Bullet-journaling is still one aspect of my practice, but not for task-management - just for remembering what I did.

I've been at it ever since.

I'm 60 now, so that's 10 year's worth of life captured, in 46 A-5 sized Volumes (I'm now on Volume 47)

My general process

I write short bullet points at the beginning of the day, and add others if necessary at other times. These can be quickly scanned when searching for things at a later data.
I do small sketches (usually pen & ink & watercolour) of little things that will jog my memory later

I write a long-form entry each morning telling the story of the previous day, usually between 2-5 pages, after the bullet-sketch-quick-view page(s)
I stick in ephemera
- cinema tickets
- photographs
- till receipts
- bus tickets
- labels & tags from significant purchases
I write longer angsty brain-dumps on whatever topic is on my mind, to try and think-through something that's bothering me

In more bullet-journal style…..

Things I track

I keep track of various regular occurrences
I keep track of purchases, online orders etc
I keep a record of medications and medical treatments and consultations and symptoms

I keep track of the scores of our almost daily chess games

I note the weather each day
I track what days I work (I'm self-employed, so it's a bit variable)
if I've walked the dogs
if I got to bed before 11pm
I track if I cooked tea
if I went swimming
I note the family finances each week
and the electricity meter reading
and heating oil level and when the last delivery was
I note when I last changed the cooker's propane gas bottle
and when I last had a haircut (in the kitchen, by my own hand, with clippers)
and when the dog last had a haircut (at the groomer's for the sum of £60, every roughly 6 weeks)
I note the deaths of *“significant”* celebrities

I get through an A5 Leuchtturm hard-back in around 9 weeks.

My motivation?

Everything can be interesting when viewed later, from the future, even my own humdrum life.

I can now look back at almost 10 years of my “middle-age” life, in my 50s.

When I see the first frog spawn of the year…

When the car broke down, how often I've agitated the septic-tank to break up fat-blockages (yes, indeed, the joys of isolated rural living). I can find that time when we kept pigs, or the dog had a cruciate ligament rupture (and the subsequent repair & recovery).

And there's the strange blank period of a couple of months in mid-2018, when I'd had a heart-attack and I seemed unable to write anything in my diary about it (or anything else). Until I was back to normal again. I think I felt that I would remember everything anyway, without writing it down. I'm glad I did write a quick precis of the events of those weeks, even if it took a few months to get it down on paper.

I'm inspired by Mass Observation, the diaries of Alan Bennet, the writings of Simon Garfield, the passionate call-to arms in Irving Finkel's video (see below).

Indexing

In December 2023 I decided that I need a way of finding old entries/events/facts etc. so I started an Index…. more later in a blog post…

The Great Diary Project

The wonderful Irving Finkel mini lecture on You Tube Rescuing unwanted diaries gives a feel of why I think capturing everyday life, in ordinary peoples' diaries, is important.

The result of Irving's discovery of the importance of diaries is the The Great Diary Project

There is a similar project in the USA The American Diary Project

Anne Lister

Now well known after the BBC dramatization as “Gentleman Jack” - Anne Lister lived in the 18th Century, was a land-owning woman (unusual) and most famously, gay.

Her diaries were written partly in a “secret” code, to hide the more personal aspects.

They were researched and sections published in 2 volumes by Helena Whitbread.

Anne Lister

I've read the first volume, and it's a fascinating insight into life in the 1820s - leaving aside the sexual aspects - just the practicalities of life, the leeches and quack medical treatments. The amount of walking needed to get anywhere, the poor diets (even for the wealthy). The physical discomfort tolerated (even by the wealthy).

John Gadd

I recently discovered John Gadd and his diary.

He seems to have kept a very similar style of journal to mine - writing daily in one book storing EVERYTHING, writing, photos, tickets, labels…. and a record of his day, his thoughts and only touching on “world news” if it particularly meant something to him.

He called it his “Omnium Gatherum”.

He died aged 90 on 2020, after keeping his diary consistently since 1947, really settling on its eventual format in the early 1970s. His diary was a memory-aid, as is mine, but of course it also captures lots of other things, mundane at the time but over a lifetime the mundane becomes the historical, and illustrate how life changes.

I'd love to see the books and look through the pages, and see how he indexed everything to make it searchable and to find anything within a few minutes.

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

____________________

PREAMBLE
____________________

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

Have fun!
deetee


____________________

INSTALLATION
____________________

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

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

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


____________________

DESK
____________________

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

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

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

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

____________________

PLEX
____________________

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

PLEX supports the following functions:
  Basic

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

Module

Fixed version Sept. 2024

User Guide

41z_deluxe_manual_1_.pdf

ZK?YN (UPDATE 5/8/22)

ZK?YN Info

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.

R Pi Image files

R Pi Image files

Various tips and tricks for working with Raspberry Pi Disk Images

Taking an image

remove SD card from Pi
insert into PC
unmount the image partitions if they get auto-mounted

take the image using dd

sudo dd if=/dev/mmblahblah of=name_of_image.img bs=4M

wait….. and wait….
this can now be either
1. saved as it is (possibly a big file)
2. compressed with gzip
```
gzip name_of_image.img
```
an alternative is to make sure the image is as small as it needs to be, appropriate to the space actually needed by the installed OS.

Using ''losetup'' to work with the image file

The image can be used as a loop device and then mounted as a normal disk to allow access to the files etc.

To access the image as a loop device you let losetup find the partitions automatically and convert them to to loop partitions loop0p1 (the /boot partition) and loop0p2 the root partition. You can then mount whichever one you need.

gm4slv@laptop:~/piimg $ sudo losetup -Pf igate.img
gm4slv@laptop:~/piimg $ lsblk
NAME      MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT
loop0       7:0    0   4.3G  0 loop
├─loop0p1 259:0    0   256M  0 part
└─loop0p2 259:1    0     4G  0 part
sda         8:0    0 298.1G  0 disk
├─sda1      8:1    0 235.1G  0 part /
├─sda2      8:2    0     1K  0 part
├─sda3      8:3    0  50.9G  0 part
└─sda5      8:5    0  12.1G  0 part [SWAP]
sr0        11:0    1  1024M  0 rom
gm4slv@laptop:~/piimg $ sudo mount /dev/loop0p2 /mnt
gm4slv@laptop:~/piimg $ cd /mnt
gm4slv@laptop:/mnt $ ls
bin  boot  dev  etc  home  lib  lost+found  media  mnt  opt  proc  root  run  sbin  share  srv  sys  tmp  usr  var
gm4slv@laptop:/mnt $ cd etc/
gm4slv@laptop:/mnt/etc $ cat hostname
igate
gm4slv@laptop:/mnt/etc $

This allows you to change files (one example is to set a fixed IP address in /etc/dhcpcd.conf) as required.

Shrinking the image

If the OS had been expanded after install to fill the whole SD Card space there is now a lot of pointless wasted space in the image that

takes up disk space to store
makes copying to a new SD card slow
makes it impossible to copy to a smaller card

The image can be shrunk to a more appropriate size.

The gist of it is here

unmount the loop device:
```
sudo umount /mnt
```
use gparted (need to be at a machine with a graphical session) to shrink the partition to a more suitable size, leaving some room for safety
dispose of the loop device
```
sudo losetup -d loop0
```
The *.img file is still the same size, but the partitions within the file are smaller, the rest of the space needs to be stripped from the *.img file with truncate
Use fdisk to inspect the image file to see where the partitions start and end

gm4slv@laptop:~/piimg $ sudo fdisk -l igate.img
Disk igate.img: 4.25 GiB, 4563402752 bytes, 8912896 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: dos
Disk identifier: 0x38ea48c4
 
Device     Boot  Start     End Sectors  Size Id Type
igate.img1        8192  532479  524288  256M  c W95 FAT32 (LBA)
igate.img2      532480 8912895 8380416    4G 83 Linux

The second partition ends at block 8912895 so you shrink the filesystem to this point (plus one). This requires the calculation of the actual number of bytes, based on the block size of 512 bytes.
Either calculate it yourself, or put the calculation in the command:
- ```
 sudo truncate --size=$[(8912895+1)*512] name_of_image.img
```

Voila, a smaller image on file which uses just enough space for the already known to be working OS

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

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

gui_smeter.py

CRT SS9900

Multi-Mode 10m/11m/12m

Background

I wanted a mobile 10m radio for use on 10m FM, and occasionally SSB, to try and re-capture the fun I had in the early days of being a ham (1983). Looking around I found a lot of choice of radios covering 12m and 10m amateur bands, and (of course) all the space in between containing the 11m/CB bands.

I bought a CRT9900 which seemed to offer the best versatility - it's more like a ham radio than a channelized CB.

It's hardly been used - I don't think I've ever had a QSO with it yet - so I now intend to make a concerted effort to get some use from it, and even looking at 11m when 10m is moribund.

Propagation conditions should be improving as Solar Cycle 25 peaks, and (writing this in early May 2023) the summer Sporadic-E season should also bring some inter-Europe propagation too.

p.s. I even have a CB callsign from the Charlie Tango group : “108 CT 2182” (108 = Scotland and I asked for 2182 as a nod to SSB marine radio)

Icom IC-706

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

HF 100W
6m 100W
2m 10W

Background

From the Silent Key equipment of Peter GM0CXQ

First impressions

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

Initial tests

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

Repairs and Modifications

Cleaning

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

6m LPF relays

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

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

MARS TX Mod

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

Signalink USB

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

Rigctl / Hamlib

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

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.

HF Weather FAX

— John Pumford-Green 22/10/22 08:25

I thought I'd have a look at some other HF signals and found that Fldigi will decode Weather FAX.

I found a big list of active FAX stations:

https://www.weather.gov/media/marine/rfax.pdf

and set up Fldigi and my Icom IC-R75.

PT. REYES, CALIFORNIA, U.S.A.

I'd like to receive FAX from NMC/Point Reyes in California…. and perhaps I'll leave fldigi monitoring one of their frequencies for a period

4m FM

Low Band PMR and 4m Ham band

Background

The PMR radio system for the Shetland Islands Council (SIC) Roads dept. is being re-engineered (summer 2023) with new base station radios and a new IP based microwave link network.

I thought I would set myself up with the ability to monitor, and test coverage, both mobile and at home. I found my old FM1100 and also was given a selection of other ones by SIC, as well as the PDP to program them.

My plan is to configure the radios for both 4m ham band and SIC roads network.

CCIR493 Selcall

HF Selcall Experiments

Background

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

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

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

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

Basic details

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

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

At its simplest a selcall transmission can be either:

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

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

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

Jenal SC2 Mic

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

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

SC2 Handbook

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

Scanning

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

Previous Selcall Activity

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

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

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

Selcall Activity 2023

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

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

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

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

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