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

Various methods to test the speed of calculators

HP Museum Benchmarks

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

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

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

For 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

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.

Date Start	Date Check	Accumulated Error (s)	Rate Error (s/d)	Comments

24/5/22				new correction C=-42.47
24/5/22	25/5/22		-0.3	new correction in wrong direction?
28/5/22			-0.3	still over-corrected. New factor: -37.5. DM41X reports this is a correction of -35.3ppm
28/5/22	31/5/22		+0.2	Now under-corrected? Difference across 3 days is only 0.5 seconds, so perhaps needs longer to reduce reaction-time-error
28/5/22	28/6/22		+0.1	Almost 1 month later. Delta 31/5/22 = -15.7s, Delta 28/6/22 = -11.6s. +4.1s in 28 days

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

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.

LF15C - firmware for the DM15

←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.

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.

    Please note:
    When in HEX mode enter numbers >9 with a dot (ie .1=a, .6=f).
    To set the OFFTIME (default is 60s) enter the desired value (5-300) in
    seconds to the stack and press Toff (fGSB6).
    Be careful when setting the lcd brightness (fGSB4, 0-64) or lcd voltage
    (fGSB5, 0-5-7). The default values are 0 and 5.
    Get/set date and time from/to the real time clock (RTC) with the gGSB menu.
    The format for the date on the stack is YY.MMDDw (where w is the number of
    the weekday (0=Monday). The format for the time is HH.MM.

TTOP
____________________

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

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

TEX
____________________

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

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

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

Hardware / Firmware issue

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

email re: hardware mod

Dear valued customer,

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

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

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

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

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

To address this issue, we offer several solutions:

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

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

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

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

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

Thank you for your continued support and patience.

Best regards

Michael Steinmann

SwissMicros

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

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

←6502 Project

Update Sept 2022

Some recent modifications and additions

Hardware

2 more 65C22 VIA chips to give a total of 3 VIAs providing six 8-bit I/O ports.
- VIA #1 ($6001) : Port A = Keypad
- VIA #1 ($6000) : Port B = LCD_1 (4×20 in 4-bit mode)
  - VIA #1 : IRQ connection to CPU for keypad and CB1 & CB2 buttons
  - VIA #1 Port B handshaking CB1 and CB2 connected to debounced buttons for user input experiments
- VIA #2 ($5001) : Port A = Spare
- VIA #2 ($5000) : Port B = SPI (bit0,1,2,6), Piezo Sounder (bit7)
  - VIA #2 : T1 Timer = square wave generator for sounder using Port B bit7
- VIA #3 ($4801) : Port A = LCD_2 (2×16 in 4-bit mode)
- VIA #3 ($4800) : Port B = Spare
  - VIA #3 : T1 Timer = System Clock Ticks at 10ms rate via NMI connection to CPU
main LCD changed to a 4 line by 20 character display
2nd LCD (2 x 16) added on VIA #3 Port A
LED indicator plug-in boards made to give easy visual indication of VIA output port state
Piezo sounder connected to VIA #2 Port B, bit 7
SPI interfacing using VIA #2 Port B
Buttons for controlling interrupt driven events, each de-bounced with a 555 monostable
555 timer as a power-on CPU reset

Firmware

ROM Monitor code extended to support the new hardware.

SPI transceive to communicate with a basic SPI slave running on a PyBoard
LCD #2 display of either “Mission Time” or SPI TX/RX data to/from PyBoard
code to send audible beeps of different pitch/duration (controlled by the 2 buttons)
keypad - confirmation keypress beeps
Byte (binary) to ASCII decimal conversion to show 16-bit/2-byte binary data as a human readable decimal number
Use of FLAGS to control background tasks extended/explored

Next Steps

add Serial Interface using Rockwell 65C51 ACIA and MAX232
learn how to code for interacting via serial interface
connect to a Wyse-185 Serial Terminal
[✓ John Pumford-Green, 2022-09-26]~~add DS1306 RTC via SPI~~
[✓ John Pumford-Green, 2022-09-26]~~move system clock back to VIA_1 using IRQ interrupt~~
[✓ John Pumford-Green, 2022-09-26]~~move beep to VIA_3 port B7~~
[✓ John Pumford-Green, 2022-09-26]~~move SPI interface to VIA_3 port B, for future connection to DS1306 RTC~~
- this will leave :
  - VIA_2 ports A & B free for external use
  - VIA_3 Port A = LCD2
  - VIA_3 Port B = Beep and SPI/RTC

DM41X Polynomial Solver

anonymous@undisclosed.example.com (Anonymous) — Sun, 19 Apr 2026 20:11:18 +0000

←Hints & Tips

DM41X Polynomial Solver

Advantage Pac Polynomials

Assuming Advantage Pac is plugged in…

Finds all roots, including complex ones.

Save to registers

To save the discovered roots in registers

Enter the polynomial coefficients as normal
prior to pressing RT to do the solve SET FLAG 06
- ShiftSF06
This will save the discovered roots in R24 upwards
- saves in pairs as REAL and IMAGINARY
  - R24 = REAL root 1
  - R25 = IMAG root 1
  - R26 = REAL root 2
  - R27 = IMAG root 2
  - etc
  - etc

Roots of a quadratic

To find the roots of a simple quadratic (with 2 real roots)

x² - 3x + 2 = 0

XEQ ALPHAPLYALPHA
Asks for DEGREE=?
- this is the highest power of x in the polynomial
- enter 2 R/S
Asks for a2=?
- the coefficient of x²
- enter 1 R/S
Asks for a1=?
- the coefficient of x
- enter 3 CHS R/S
Asks for a0=?
- the constant term
- enter 2 R/S
Display shows FX RT NEW
- FX = Function value at your choice of x
- RT = Root(s) of the entered polynomial
- NEW = Enter a new polynomial
- Choose RT B
Display shows ROOT = 2.0000
- to see next root press R/S
Display shows ROOT = 1.0000

The roots of our quadratic are 2 and 1

Higher order with complex roots

Either press TAN (J) to get the menu, and then NEW (LN) or XEQ PLY again

4x⁴ - 8x³ - 13x² - 10x + 22 = 0

This should have 4 roots, and most likely some will be complex.

DEGREE=?
- 4 R/S
a4=?
- 4 R/S
a3=?
- 8CHSR/S
a2=?
- 13 CHSR/S
a1=?
- 10 CHSR/S
a0=?
- 22R/S
FX RT NEW
- RT B

Roots are displayed:

U = -1.0000 R/S
V = 1.0000 R/S
U = -1.0000 R/S
V = -1.0000 R/S
ROOT = 3.1180 R/S
ROOT = 0.8820 R/S
FX RT NEW

The 4 roots are

-1 + j 1
-1 - j 1
3.1180
0.8820

Cube Roots of minus 8

If x is the cube root of minus 8 then x³ = -8 and as a polynomial x³ + 8 = 0

Simply use 0 as the coefficient of X² and x

XEQ ALPHAPLYALPHA
Degree=? 3 R/S
a3=? 1 R/S
a2=? 0 R/S
a1=? 0 R/S
a0=? 8 R/S

RT B
- ROOT = -2.0000 R/S
- U = 1.0000 R/S V = 1.7321
- U = 1.0000 R/S V = -1.7321

Roots are
- 2.0000
- 1 + j 1.7321
- 1 - j 1.7321

Code & Command Snippets

Windows WiFi Disconnect

Windows will disconnect a WIFI connection when it discovers there's no WAN internet - presumably Windows thinks ALL networks are connected to the Internet and this prevents using WIFI for an isolated LAN, and also throws you off the WLAN whenever the ADSL connection fails, even when you're busy using only internal LAN sessions.

THIS IS WRONG BEHAVIOUR.

I found a solution, and typically it's a REGEDIT task:

From : https://superuser.com/questions/1650052/how-to-keep-windows-10-connected-to-wifi-without-internet

Add a Registry DWORD “NoActiveProbe” value “1” at Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\NetworkConnectivityStatusIndicator

Job Done. You stay on your LAN even when the interwebs is down.

Chrome redirects

To remove a “permanent redirect” - e.g. from an http to an https URL - I found the answer here:

https://www.neilwithdata.com/chrome-redirect-forget

Open the Chrome Developer Tools (F12)
Go to the Network tab and make sure Disable cache is ticked
Reload (or navigate to) the page you no longer want to be redirected while keeping the dev tools open.

Vim Pasting

I recently had problems pasting text into Vim by the traditional RIGHT click method. Vim would enter Insert(VISUAL) mode instead.

One solution when using Putty is to use its own mechanism :

SHIFT+INS

I prefer to use RIGHT click, as it's more natural so I found the solution is to add

set mouse-=a

to ~/.vimrc

This solves the problem, and I don't need to use nano when editing text files on my remote server via SSH using Putty.

Raspberry Pi Stuff

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

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

My configs

#includeifexists custom/extensions.conf

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

Installing DVswitch

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

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

Adding DVSwitch repository keys

As root :

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

Configuring DVSwitch

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

/opt/Analog_Bridge/Analog_Bridge.ini

and

/opt/MMDVM_Bridge/MMDVM_Bridge.ini

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

/etc/asterisk/rpt.conf

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

and setting Analog_Bridge.ini to match:

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

Testing

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

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

rpt cmd 2100 ilink 3 1999

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

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

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

So Far So Good

To boost the audio via the bridge

Analog_Bridge.ini to change from AUDIO_UNITY to AUDIO_USE_GAIN

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

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

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

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

Allmon2 / supermon

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

Laptop FreeBSD

←Computers

Laptop FreeBSD

I moved my Dell laptop from Devuan Linux to FreeBSD and here are some things I needed to do and some things I did for convenience….

Graphics

I found the basic install of the recommended drm-kmod package and i915kms driver wouldn't work - it crashed/hung during boot.

Removing this package and using the SCFB video driver worked, but didn't give (for example) DPMS control of the LCD screen.

I used SCFB temporarily be adding an xorg conf file 20-vesa.conf to /usr/local/etc/X11/xorg.conf.d/

Section "Device"
        Identifier "Card0"
        Driver "scfb"
EndSection

This was a reasonable workaround, but I found the solution to using correct Intel i915kms driver here : https://blog.hofstede.it/freebsd-150-on-the-thinkpad-t480-efficient-stable-and-8-hours-on-battery/

This is what worked:

Installed new packages

drm-latest-kmod

gpu-firmware-intel-kmod-kabylake

added to /etc/rc.conf

kld_list="i915kms"

added to /boot/loader.conf

# Graphics and power tuning
i915kms_load="YES"
drm.i915.enable_rc6=7
drm.i915.enable_fbc=1
drm.i915.lvds_downclock=1
drm.i915.enable_psr=1
compat.linuxkpi.i915_disable_power_well="0"

i915kms now loads and I have access to DPMS for turning off the LCD screen.

LCD Panel on/off

I made a few small shell scripts to assist in controlling the battery consumption by being able to alter LCD brightness, and turn the LCD off via DPMS and makde i3 shorcuts to them.

(later I made the same key actions for DWM when I moved back to using DWM)

now I can “$mod+Shift+o” to reduce brightness and “$mod+Shift+p” to increase it, and “$mod+Shift+i” to turn the LCD screen off completely.

I also added a devd rule to turn the LCD screen off when the lid is closed - this confused me initially, as it worked when testing it by adding the rule, restarting devd and testing, from within an X-Session…. but didn't work when devd was started during bootup…

This was due to the lack of DISPLAY if the script was triggered from “outside” the X session. Changing the script to set the DISPLAY variable was the solution.

/etc/devd/rules.d/lid.conf

notify 20 {
match "system" "ACPI";
match "subsystem" "Lid";
match "notify" "0x01";
action "/home/g4slv/bin/on";
};
notify 20 {
match "system" "ACPI";
match "subsystem" "Lid";
match "notify" "0x00";
action "/home/g4slv/bin/off";
};

The lid actions call one of these →

~/bin/on

#!/usr/local/bin/bash
 
su g4slv -c 'setenv DISPLAY :0.0 && /usr/local/bin/xset dpms force on'

~/bin/off

#!/usr/local/bin/bash
 
su g4slv -c 'setenv DISPLAY :0.0 && /usr/local/bin/xset dpms force off'

Other tweaks

Small scripts to automate swithing between Wifi and Ethernet

net_wlan.sh

#!/bin/sh
 
doas service netif stop em0 
doas service netif start wlan0
doas service dhclient restart wlan0

net_eth.sh

#!/bin/sh
 
doas service netif stop wlan0 
doas service netif start em0
doas service dhclient restart em0

Serial USB Adaptors

To get access to a USB serial device as normal user (as long as I'm in the wheel group) I added a rule in /etc/devd.conf

notify 100 {
        match "system"          "DEVFS";
        match "subsystem"       "CDEV";
        match "type"            "CREATE";
        match "cdev"            "ttyU[0-9]+";
        action "chmod ug+rw /dev/$cdev";
 
};

This makes the device R/W for the wheel group. Without this rule (the chmod part) the device is only R/W for root.

DM41X 41z Module

anonymous@undisclosed.example.com (Anonymous) — Tue, 17 Feb 2026 15:42:44 +0000

←Calculators

DM41X 41z Module

Keyboard Overlay

Setup

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

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

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

Quick Ref

Z = Σ+

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

Basic Operation

enter two numbers and add them together

The ''natural'' entry method

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

Enter a real number

2.75 + j 0
- 2.75 Z Z RCL

Enter an imaginary number

0 + j 3.1415 (i Pi)
- SHIFT π Z Z XEQ

Use it to calculate with....

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

Parallel Impedances

This involves the complex inverse function Z 1/x

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

convert to Rectangular ⇔ Polar operation

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

enter a number directly in Polar format

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

Cubic Roots

Rectangular

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

The 3 cube roots of -8 are

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

Polar

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

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

2 ∠ 60.000
2 ∠ 180
2 ∠ -60.000

Alternate input method

BEWARE

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

gotcha

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

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

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

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

use ↑IM/AG instead

The natural entry mode is much better

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

Useful Functions

The Advantage Pac Module adds several features not normally found on the HP41.

The most useful to me are

MATRX : Simple square matrix “Simultaneous Equation” solutions
CFIT : Fitting data to various curves : LIN/LOG/E^x/Power
SOLVE and INTEGrate : similar to the HP15C/DM15L functions
PLY Polynomial Solver
Matrix (more extensive than the one above)
TVM : Finance calculations

Also available are

Complex Numbers
Number Bases and Boolean Logic

- these are better handled in the Angel Martin modules DM41X 41z Module and DM41X HP16C Module

These are less useful to me (at the moment)

Vector
Differential Equations
Co-ordinate Transformations

DM15L Non-linear Curve Fit

anonymous@undisclosed.example.com (Anonymous) — Mon, 06 Apr 2026 12:40:53 +0000

←Hints & Tips

DM15L Non-linear Curve Fit

Using DM15L/HP15C built-in L.R function to fit non-linear curves

Background

The idea is that the 3 different non-linear function forms can be expressed as linear expression y = m.x + c if we manipulate the x or y values before adding them to the statistics accumulator.

The different curves require different treatment of the data to linearize, and the resulting coefficients may require treatment too.

Tl;dr

Method for Exponential

y = b.e^ax

Ln(y) = a.x + Ln(b)

Enter Accumulation data	`y_i gLn x_i ∑+`
Calculate coefficients	`fL.R.e^x`
Estimate ŷ & r for a new `x`	`x fŷ.r e^x`

Method for Logarithmic

y=a.ln(x)+b

y = a.Ln(x) + b

Enter Accumulation data	`y_i Enter x_i gLn∑+`
Calculate coefficients	`fL.R.`
Estimate ŷ & r for a new `x`	`xgLn fŷ.r`

Method for Power

y=b.x^a

Ln(y) = a.Ln(x) + Ln(b)

Enter Accumulation data	`y_i gLn x_i gLn∑+`
Calculate coefficients	`fL.R.e^x`
Estimate ŷ & r for a new `x`	`x gLnfŷ.re^x`

Exponential

y = b.e^ax

This can be expressed as Ln(y) = Ln(b) + a.x

Ln(y) = a.x + ln(b)

compare with a linear expression y = m.x + c

Using Ln(y) and x as data points and running the L.R. function will give coefficients equal to a and ln(b)

You can obtain the actual value of b finding its antilog with e^x.

Once the L.R. has run you can find estimates of ŷ by running the fŷ.r to get the estimate of Ln(y) and then finding its antilog with e^x

Mechanism

To enter the data points you convert the y data to its Ln first, then accumulate as normal

y_i gLn x_i ∑+

Once all the data has been entered you get the Linear Regression coefficients a & b fL.R. and e^x to correct the b LR coefficient.

Example Data

y	2.8	3.6	5.8	8.0
x	0.8	1.1	1.7	2.1

fClear ∑

2.8 gLn 0.8 ∑+

3.6 gLn 1.1 ∑+

5.8 gLn 1.7 ∑+

8.0 gLn 2.1 ∑+

All data is in the accumulator, now do the Linear Regression fL.R.

This gives a and Ln b coefficients

Y: 0.805 = a

X: 0.3897 = ln b

so we need to find b so e^x

Y: 0.805 = a

X: 1.476 = b

Equation estimation is therefore y = 1.476 e ^0.805x

I made the data table by using the equation y = 1.5 e ^0.8x and then used approx. y values for the data table…. so the estimate looks pretty good

To do an estimation of y when x = 0.9

0.9 fŷ.r e^x

Y: 0.999962 = r correlation coefficient

X: 3.047425 = ŷ estimation

Method for Exponential

Enter Accumulation data	`y_i gLn x_i ∑+`
Calculate coefficients	`fL.R.e^x`
Estimate ŷ & r for a new `x`	`x fŷ.r e^x`

Logarithmic

y = a.ln(x) + b

Compare to a linear expression y = m.x + c shows the logarithmic curve is linear if we use Ln(x) as we accumulate data points.

The L.R. will provide the actual a and b coefficients.

To estimate ŷ first find the Ln of x then use the fŷ.r

Mechanism

y_i Enter x_i gLn∑+

Calculate LR Coefficients

fL.R.

Calculate estimated ŷ by finding the Ln of your x value first and then using fŷ.r

xgLnfŷ.r

Example Data

y	1.5	1.7	1.8	2.1
x	0.8	1.7	2.6	4.9

fClear ∑

1.5 Enter 0.8 gLn∑+

1.7 Enter 1.7 gLn∑+

1.8 Enter 2.6 gLn∑+

2.1 Enter 4.9 gLn∑+

Linear Regression Coefficients : fL.R.

Y: 0.324 = a

X: 1.544 = b

Equation y = 0.324 . Ln(x) + 1.544

Estimate ŷ for X = 3

3 gLn fŷ.r

Y: 0.985 = r, correlation coefficient

X: 1.900 = ŷ, estimation

Method for Logarithmic

Enter Accumulation data	`y_i Enter x_i gLn∑+`
Calculate coefficients	`fL.R.`
Estimate ŷ & r for a new `x`	`xgLn fŷ.r`

Power

y = b.x^a

This can be rearranged as Ln(y) = Ln(b) + a.Ln(x) or Ln(y) = a.Ln(x) + Ln(b)

Compare to a linear expression y = m.x + c

Our expression will be a straight line if we accumulate Ln(y) and Ln(x)

The coefficients given by the L.R. function will be a and Ln(b) - so to get the real b coefficient we find its antilog e^x

We get the estimate for ŷ we first find the Ln of our chosen x and then use the ŷ.r to get Ln(ŷ) and then e^x to get ŷ

Mechanism

Accumulate using

y_i gLn x_i gLn∑+

Calculate LR Coefficients

fL.R.e^x

Calculate estimated ŷ

xgLnfŷ.re^x

Example Data

y	1.3	2.2	3.3	4.4
x	0.6	1.3	2.4	3.6

fClear ∑

1.3 gLn 0.6 gLn∑+

2.2 gLn 1.3 gLn∑+

3.3 gLn 2.4 gLn∑+

4.4 gLn 3.6 gLn∑+

Linear Regression Coefficients : fL.R.e^x

Y: 0.678 = a

X: 1.837 = b

Equation : y = 1.837x^0.678

Estimate ŷ for X = 3

3 gLnfŷ.re^x

Y: 1.000 = r, correlation coefficient

X: 3.869 = ŷ, estimation

Method for Power

Enter Accumulation data	`y_i gLn x_i gLn∑+`
Calculate coefficients	`fL.R.e^x`
Estimate ŷ & r for a new `x`	`x gLnfŷ.re^x`

←Hints & Tips

DM32 Curve Fit

CFIT Program from the Owner's Manual

State File

The listing from the Owner's Manual has been entered into the calculator and saved as a State File

cfit.d32

Use

The program provides the usual set of Curve Fitting for Straight Line, Exponential, Logarithmic and Power curves, automating the same techniques as the manual method for DM15 described here DM15L Non-linear Curve Fit .

There is no “best fit” algorithm, which means you need to decide in advance which of the 4 curve types to fit, before entering the data. If you choose a different curve you have to enter the data again.

Choose a Curve

Each curve type has a separate program label

XEQ S : Straight Line
XEQ E : Exponential
XEQ L : Logarithmic
XEQ P : Power

Enter Data

Data is entered the same way whichever of the 4 programs is chosen.

X-value R/S Y-value R/S
X-value R/S Y-value R/S
X-value R/S Y-value R/S
X-value R/S Y-value R/S

Run the Curve Fit

Once all the data is entered you run the fit using XEQ R

This gives the various paramaters

R-value (correlation coefficient) R/S
B-value R/S
M-value R/S
Prompt for an x-value to use to calculate ŷ - enter a number R/S
- ŷ is shown for that x-value
Prompt now for a y-value to use to calculate an estimate of x R/S
- x estimate is shown for that y-value
Prompt for a new x-value to use to calculate ŷ R/S
- this goes on until you want to stop….
- press C to quit

Curve equations

Straight Line y = B + Mx
Exponential y = Be^Mx
Logarithmic y = B + M Ln(x)
Power y = Bx^M

Examples

Logarithmic

x	0.3	1	2	3	4	5
y	-1	2	3.8	5	5.6	6

0.3 R/S 1 +/- R/S
1 R/S 2 R/S
2 R/S 3.8 R/S
3 R/S 5 R/S
4 R/S 5.6 R/S
5 R/S 6 R/S

Run the fit

XEQ R
R=0.99932 R/S
B=2.05210 R/S
M=2.5359 R/S
enter an x-value to calculate an estimate of y
- 2.5 R/S
- y? 4.37571
enter a y-value to calculate an estimate of x
- 0 R/S (what is x-value where the curve crosses the x-axis at y = 0? The solution to the equation)
- X ? 0.44520
finish C

Results

The curve equation is y = 2.05210 + 2.5359Ln(x)
The values for R, B and M are stored in register-variables R, B and M for future use
- e.g. make an EQN
- Y = B + M x Ln(X)
- the equation can be evaluated, solved or integrated using the stored values for B and M
Until a new Curve fit program is run, or anything is done to change the Statistics Registers, you can re-run the fit with XEQ R to allow more y and x estimates to be made

Use

This set of programs will provide real and complex roots of polynomials up to 5^th order. The coefficient of the highest term is assumed to be 1 and all the coefficients must be normalized to make this so.

Quadratic

x² - 3x + 2 = 0

Run XEQ P
Enter the order at the prompt for F?
- 2 R/S
Enter coefficient B

Enter coefficient A
- 2 R/S
1^st root is shown
- X=1.0000 R/S
2^nd root is shown
- X=2.0000 R/S
quits

The two roots of x² - 3x + 2 = 0 are 1 and 2

4-th order

4x⁴ - 8x³ - 13x² - 10x + 22 = 0

This has a non-unity value for the highest term, so all the coefficients need to be divided by 4 to make it so, this can be done as they are entered

XEQ P
Enter order 4 at the prompt for F?
- 4 R/S
Enter the coefficients starting at the second one (for x³) and dividing by 4
- 8 +/- ENTER 4 ÷ R/S
- 13 +/- ENTER 4 ÷ R/S
- 10 +/- ENTER 4 ÷ R/S
- 22 ENTER 4 ÷ R/S

DM32 Simultaneous Equations

Local copy simeq.d32

Overview

This set of programs allows the solution of 3×3 and 2×2 systems of equations, as well as the inverse and determinate of the matrix representing the coefficients.

The set of equations is represented by a 3 x 4 array of numbers, with the first 3 columns representing the coefficients of the equations and the 4th column the “value” of the equations.

For example

Ax + Dy + Gz = J

Bx + Ey + Hz = K

Cx + Fy + Iz = L

These equations can be represented in matrix form

| A D G | | x | | J | | B E H | | y | = | K | | C F I | | z | | L |

This is effectively

A x X = B

and therefore

X = B / A

X = B x A^-1

The unknown matrix is obtained by multiplying B by the inverse of A

They are entered sequentially in the order

ABCDEFGHIJKL

Use

Enter the values of the 3×3 matrix and the 3×1 column vector by using prog. A

XEQ A
Enter each value at the prompt followed by R/S
Once all values A → L are entered you can
- find the determinant of the coefficient matrix with prog D
  - this is not required for a simple solution, but might be useful for other purposes?
- Invert the coefficient matrix A with prog. I
  - XEQ I
- Multiply the column vector by this inverse matrix using prog. M
  - XEQ M
  - This gives the resulting X, Y and Z by pressing R/S to step through them

Examples

3 x 3

A system of equations with 3 unknowns x, y and z

23x + 15y + 17z = 31

8x + 11y - 6z = 17

4x + 15y + 12z = 14

Beware!

You enter each value in sequence going down the columns in sequence

Which is the opposite sense to the way matrices are entered in DM15L and DM41X

XEQ A
- 23 R/S
- 8 R/S
- 4 R/S
- 15 R/S
- 11 R/S
- 15 R/S
- 17 R/S
- 6 +/- R/S
- 12 R/S
- 31 R/S
- 17 R/S
- 14 R/S
Find the inverse XEQ I
Multiply XEQ M
Display shows solutions
- X = 0.930622 R/S
- Y = 0.794258 R/S
- Z = -0.136364
You can inspect the inverted matrix by running A again
- XEQ A
- A ? 0.048 R/S
- B ? -0.026 R/S
- etc….etc…
You can re-invert A back to the original state by running prog I again
You can see the determinant of A by running prog D

2x2

The programs expect a 3×3 matrix. If the system is 2×2 you have to use dummy values to pad out to 3×3

Set C, F, H, G, L = 0 and I = 1

e.g.

2x + 3y = 6

8x - 4y = 9

This becomes

2x + 3y + 0z = 6

8x - 4y + 0z = 9

0x + 0y + 1z = 0

and is entered

XEQ A
- 2 R/S
- 8 R/S
- 0 R/S
- 3 R/S
- 4 +/- R/S
- 0 R/S
- 0 R/S
- 0 R/S
- 1 R/S
- 6 R/S
- 9 R/S
- 0 R/S
Find the inverse XEQ I
Multiply XEQ M to find the unknowns
- X = 1.59375 R/S
- Y = 0.93750 R/S
- Z = 0.00000 C

DM41X Matrix

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

←Hints & Tips

DM41X Matrix

Matrix functions in the Advantage Pac

Background

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

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

There are many commands, the most used are those for

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

Shortcuts to Matrix Commands

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

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

I have the following

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

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

Basic Workflow

All matrix addressing is done via the ALPHA register

Dimension a new Matrix

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

Populate a new Matrix

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

For a 3×3 matrix

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

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

Determinant

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

CST F
-50.000

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

Multiplication

Using M*M

For matrix multiplication you need 3 matrix definitions:

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

To multiply two matrices together they must have the correct dimensions

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

Create Matrix A

Follow the same procedure as above.

Make sure ALPHA has only the letter A

A different numerical example

A will be a 3×2 matrix

use MATDIM via CST menu
- 3.002 CSTA

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

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

Create Matrix B

B will be a 2×2 matrix

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

ALPHA B ALPHA
2.002 CSTA

| 2 3 | | 4 5 |

* Use MEDIT via CST menu

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

We now have defined the matrices to be multiplied together.

Create Matrix C

We need a results matrix C

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

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

ALPHA C ALPHA
3.002 CSTA

That's enough to create the results matrix

Multiply the matrices

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

View the result

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

The result in C is

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

System of Equations

A simple example first

3 unknowns

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

Matrix representation

Matrix A

Create Matrix A

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

Create Matrix B

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

Run MSYS

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

Examine Matrix B

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

The solution

x = 1.5 y = -3.8 z = 8.4

Matrix A

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

Another way to solve a system

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

A X C = B

C = B / A

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

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

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

The Complex Matrix

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

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

Example Definition

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

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

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

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

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

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

Multiplication of Complex Matrices

Create a second matrix

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

| 3+j4 | | 2+j6 |

Dimension second matrix

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

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

Create a result matrix

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

ALPHA C ALPHA
4.002 CST A

Multiply A X B = C

ALPHA A , B , C ALPHA
CST E

Inspect Result Matrix C

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

The result matrix is therefore

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

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

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

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

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

Systems of Complex Equations....

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

Clearing Up Extended Memory

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

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

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

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

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

←Hints & Tips

DM41X PPC ROM Solve & Integrate

Solve (SV)

Similar to other Solvers (e.g. the Advantage Pac Solve) but with some minor differences to be aware of.

ASTO the Global Label (name) of the program (in this example it's LBL AA) containing the expression to be solved in Register 06
- ALPHAAAALPHA
- XEQALPHAASTOALPHA06
The program with the expression to be solved must be written as though unknown x is on the x-stack only
- other solvers “fill the stack” with x
- here you need to manipulate the stack to get x as needed. It's easiest is to just ENTER ENTER ENTER and then treat the stack the same as other solvers (i.e. as if it's filled with x and you use x<>y to pull a fresh copy of x as needed in the expression).
Put a “step size” in y and a “start value” in x (e.g. -3)
- 0 ENTER -3
run SV

example

2x² + 3x - 4 = 0

Integrate (IG)

This is very similar to SV - the main difference is that the Global Label for the program containing the expression to be integrated is stored with ASTO in Register 10.

I'm using AA as a general scratchpad Program label for use with Solve and Integrate…

ALPHAAAALPHA
XEQALPHAASTOALPHA10

For SV it's R06.

Otherwise carry out the same procedure for storing the expression.

Time taken for integration, and the accuracy obtained, is set by the display format - the more digits the longer the integration takes.

Set SCI 04 for most cases.

Set the name of the prog. in Reg 10
Edit the prog. for the expression to be integrated
Set the display format/accuracy to SCI 04
The limits of integration are set

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.

Using Solve and Integrate together

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

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

Running it

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

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

65c22 Timer values

for VIA Tone generator

Needs Ladybug module

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

Count (decimal)

{ Φ₂ / ( 2 x F ) } - 2

for 1000Hz and a 1MHz Φ₂ :

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

498d → $01F2

Run as XEQALPHATIALPHA

Prompt F for required audio tone frequency.

Enter freq

R/S

Result is the 2-byte value for T1CL & T1CH

e.g.

XEQALPHATIALPHA

R/S

Result:

$001F2

The Counter should be set to

T1CH = $01
T1CL = $F2

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

I've installed Pure Blog

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

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

Installation & Configuration

Laptop Backup via rsync

Laptop Backup via rsync

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

Backup hosts

where to put the backups for safe keeping

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

Rsync Script

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

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

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

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

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

Dokuwiki Mirror/Backup

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

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

Sandbox Server

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

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

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

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

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

Encryption

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

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

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

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

It turned out to be quite simple….

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

gm4slv@shack:~/ssl_setup$ sudo openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout /etc/ssl/private/apache-selfsigned.key -out /etc/ssl/certs/apache-selfsigned.crt
Generating a RSA private key
.......................+++++
...........+++++
writing new private key to '/etc/ssl/private/apache-selfsigned.key'
-----
You are about to be asked to enter information that will be incorporated
into your certificate request.
What you are about to enter is what is called a Distinguished Name or a DN.
There are quite a few fields but you can leave some blank
For some fields there will be a default value,
If you enter '.', the field will be left blank.
-----
Country Name (2 letter code) [AU]:GB
State or Province Name (full name) [Some-State]:Shetland
Locality Name (eg, city) []:Clousta
Organization Name (eg, company) [Internet Widgits Pty Ltd]:GM4SLV
Organizational Unit Name (eg, section) []:GM4SLV
Common Name (e.g. server FQDN or YOUR name) []:shack
Email Address []:

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

sudo a2enmod ssl

and enable the default SSL site

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

SSL enabled

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

…. but chose to continue anyway…

and it works!

Encrypted Password Plugin

Then I tested the Encrypted Passwords Plugin and it also works

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

The plugin page does say that HTTPS is needed:

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

Result!

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

Redirect to https

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

edit

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

to add

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

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

sudo service apache2 restart

Hey presto - external access to HTTPS

Diversion into the Linux Serial Console...

Diversion into the Linux Serial Console...

— John Pumford-Green 01/10/22 22:26

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

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

Linux Serial Console

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

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

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

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

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

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

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

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

DokuWiki Tweaks

DokuWiki Tweaks

Hide Revisions and Page Source for not-ADMIN in Users

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

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

Include / Blog "Read More..."

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

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

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

changing it to

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

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

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

Vector / Monobook tweaks

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

Logout errors with later versions of Dokuwiki

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

Security Token did not match. Possible CSRF attack.

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

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

I found there was a fix described on the forum:

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

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

The does work, though…

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

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

and the same for Monobook

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

Monospace font

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

I found the place to change it:

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

add the the following and adjust as needed:

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

Footer Buttons

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

For Monobook, change to

$_monobook_btns = array();

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

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

Add just the Dokuwiki and Vector/Monobook Buttons

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

Swap monobook for vector as appropriate

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

Symbol Chooser font size

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

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

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

button.pickerbutton {

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

}

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

Mobile Scaling

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

I found this thread:

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

and applied the comment-out of the line :

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

in main.php and mediamanager.php

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

Dokuwiki Timezone

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

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

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

Add DW2PDF

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

UPDATE

— John Pumford-Green 26/04/23 10:04

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

Increase maximum file size upload for Media Manager

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

Allow any file-type upload

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

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

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

Acronyms & Abbreviations

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

such as DNS and ACL

The process is described HERE

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

Bootstrap3 ThemeByNamespace

To force specific bootstrap/bootswatch themes dependant on the namespace

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

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

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

Alternative

Using the loadskin plugin

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

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

Monobook Tweaks

PDF Export Tab

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

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

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

Vector Interwiki Icons

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

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

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

Watchcheck Python code

anonymous@undisclosed.example.com (Anonymous) — Fri, 23 Jan 2026 14:13:10 +0000

Watchcheck Python code

I wrote a small python2 application to keep track of a watch/clock's daily rate error. It's a console-only mimic of an Android app that I use on my phone to track my watch timekeeping.

I wrote it mainly as a thought-experiment rather than as a fully functional piece of code.

You put the application in a directory specific to the watch and execute it from that directory. the data from each measurement is stored in a json file in the same directory.

update 23/01/26 I've modified the code to run under Python 3 - using the tool 2to3 and a minor manual tweak.

Kenwood TH-D72

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

←Rig and Key List

Kenwood TH-D72

Remote Control

The TH-D72 can be used to remotely control a TM-D710. This allows remote control of VHF Frequency/Memory Channel, TX power, CTCSS/DCS tones and to enable/disable cross-band repeat.

The remote control function uses specific DTMF sequences to instruct the TM-D710.

To enable “Remote Ctrl” mode :

Select the correct UHF uplink frequency to match the TM-D710
Turn off the TH-D72
Hold MR and PTT
Turn on the TH-D72

The display will show “Mobile Ctrl”

The TM-D710 must also be put in Remote Control mode.

On the TM-D710

select VHF mode on both sides
turn off the APRS TNC if it's on
set the left side to the wanted VHF Frequency
set the right side to the UHF Uplink/control frequency to match the TH-D72
- the first steps are done by selecting PM5 on my TM-D710
- make sure the left side/VHF is the “active” side by clicking the left volume knob
turn off
hold Rev button
turn on

The TM-D710 should now be in remote mode.

To restore normal operation repeat the same sequence of

Turn off
Hold Rev
Turn on

Successful commands sent to the TM-D710 will receive a “pip pip pip” revertive.

The commands are send using the TH-D72 keypad, remapped as:

1 = DCS On	2 = Tone On	3 = CTCSS On	A = Enter
4 = DCS Off	5 = Tone Off	6 = CTCSS Off	B = CTCSS/DCS Tone
7 = Call Ch. Mode	8 = VFO Mode	9 = Memory Mode	C = Repeater On
* = Down	0 = Power	# = Up	D = Repeater Off

to change VHF Frequency to 145.500
- 8 (VFO Mode)
- A (Enter) 145500 A (Enter)
to change to memory channel 2
- 9 (Memory Mode)
- A (Enter) 002 A (enter)
To turn on Cross-Band Repeat
- C
To turn off Cross-Band Repeat
- D

Once the TM-D710 is in the correct condition - VHF Frequency, tone, power, cross-band repeat - it's possible to restore the TH-D72 to normal operation and use it to access the cross-band repeater and use DTMF tones as normal (eg. to control another system via the repeater). Just exit “Mobile Ctrl” mode on the TH-D72

Turn off
hold MR and PTT
Turn on

You should be back in normal operation mode.

Obviously, to control the TM-D710 again (eg to disable cross-band repeat) simply go back to Mobile Ctrl mode in the same way, and send the required commands.

CCIR493 Selcall - 2026

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

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

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

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

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

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

Peer Tube Video

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

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

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

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

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

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

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.

QRSS

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

First Step

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

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

Grabber

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

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

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

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

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

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

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

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

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

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

QRSS TX

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

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

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

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

Reference Values for comparison to "Normal" behaviour

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.

The DA36

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?

Allstar - 2026

Allstar - 2026

I've put an Allstar node back on the air!

Shari Pi 70cm

I built a Shari-Pi 3U node last year, to use as a portable Allstar/Echolink node - accessing the internet via my mobile phone hotspot. At that time I also had a “hig power” 2m node running at home.

After a while I became disenchanted with radio and turned everything (even HF) off…

In May 2026 I became interested in the hobby again, and started to re-build a few parts of my station. Once the HF gear was up and running I put the Shari-Pi 70cm Allstar node online. The range is rather limited, given the low, low power and short stubby antenna - it's only intended for “within the house” coverage, after all. On a walk today I found I could hear still access, and hear it up to a mile away, almost line of site!

At the same time I'm starting to think about HF Selcall and hoping to find some other people around Europe (or further?) who might be interested. The thought struck me that Allstar would work as an “Engineer Order Wire” - a back-channel for co-ordination and discussion.

Greater Range?

How could I make the Allstar node have a better range, around my local - remote, rural, isolated - area? Should I resurrect my other Allstar node - a R.Pi, CM108 modified sound-dongle, 2m radio?

I have in the shack a TM-D710 V/UHF radio capable of cross-band repeat, I have a TH-D72 and together these make a great remote-controllable cross-band repeater system. Could I use a 2m frequency for access, cross-banding to the Shari-Pi's 70cm frequency?

Yes, it works!

Using the “Wireless Control” functions built into the TM-D710/TH-D72 it's possible to have a cross-band repeater that can be enabled & disabled over the air from the handheld, and effectively make the Allstar private 70cm hotspot into a high power 2m Gateway. (Where “high power” = 5 watts).

TH-D72 and remote control

Make the Left Side of the TM-D710 the Active side, set to the Shari-Pi's 70cm Frequency/Tone : 430.050MHz / 77Hz CTCSS
Put the Right Side of the TM-D710 on 2m : 144.9125MHz / 77Hz CTCSS
Turn off
Hold “Rev” and power on
- Radio should be in Remote Control mode
Use the TH-D72 to start/stop the Repeat function, change TX power on the 70m port, etc….
- Put the TH-D72 on the chosen 20m frequency : 144.9125MHz / 77Hz CTCSS
- Turn off
- Hold MR and PTT and power on
- This should be “Moblie Ctrl” mode
  - To Enable Cross Band Repeat : Press C (aka MR) (No need to hold PTT button)
  - To Disable Cross Band Repeat : Press D (aka Call)
- To exit “Mobile Ctrl” mode - reverse the porcess
  - Turn Off
  - Hold MR and PTT and power on
- Now it's possible to use normal Allstar DTMF commands to control the linking etc. of the Shari-Pi node, transparently it seems to be on 2m

; |t - Tone escape sequence
;
; Tone sequences consist of 1 or more 4-tuple entries (freq1, freq2, duration, amplitude)
; Single frequencies are created by setting freq1 or freq2 to zero.
;
; |m - Morse escape sequence
;
; Sends Morse code at the telemetry amplitude and telemetry frequency as defined in the

HF APRS Mobile/Portable

anonymous@undisclosed.example.com (Anonymous) — Thu, 04 Jun 2026 06:54:52 +0000

HF APRS Mobile/Portable

Initial Thoughts

My plan is to use either of

TinyTrak3 + serial GPS as a one-way tracker
Netbook with direwolf and a USB GPS
1. a tracker
2. xastir for maps etc

Either of these will interface with a Xiegu G90 and some form of mobile whip.

I may use 30m hoping to get packets directly to other iGates in Europe or use 10m and run an iGate on 10m at home. It's all on the drawing board at the moment. It will be interesting to compare local coverage between 30m and 10m as well as seeing how well 30m mobile with a short whip can perform.

Tiny Trak 3

Uses serial GPS to provide position data
Only transmits, no receive/decode
Can transmit VHF (1200bd) or HF (300bd) APRS

Mobile Journey #1 on 30m

02/05/23:

using 10m “stinger” mobile whip and G90's internal ATU / 20W
not very encouraging local coverage between mobile and home QTH
large gap in coverage - journey actually went to Lerwick and back….
next experiment will be to use 10m - hopefully antenna is more efficient on that band

03/05/12

found that the antenna used yesterday was tuned to 31MHz… short whip
swapped for 2nd whip and this is tuned to 28.2MHz…. longer whip. More efficient?

60m Transceiver

The 60m transceiver has the following features, which vary according to the loaded firmware

Channelized operation
LCD display
- Frequency
- Mode (SSB / CW)
- Modulation Source (Mic/Key/Data)
- RX / TX status
9MHz IF with Xtal filter
SSB & CW set via mode switch
Approx 3W PEP
Digital mode input/output and PTT via 9-pin D
SSB Mic input via 8-pin round “Icom” connector
Modulation Source (Mic or Data) can chosen via select switch
Scan start switch - scan a preset group of channels - cycles continuously, no “squelch”
- Use of Jenal SC2 CCIR493 Selcal microphone can be supported - including scanning

Arduino Versions

There are several different firmware versions….this is just a sample…

RX Only, with SSB, CW & scan

QRSS MEPT

anonymous@undisclosed.example.com (Anonymous) — Sun, 12 Jul 2026 15:39:55 +0000

←Arduino Projects

QRSS MEPT

I started work on my small QRSS MEPT idea with a simple Arduino / SI5351 / 16×2 LCD arrangement. The LCD is only there because I found this breadboard setup already with Seeeduino Nano, SI5351 and LCD in my box of “Arduino Project bits” - from a previous experiment - and I thought I'd keep it for the time being as a display to help in debugging (?). Once the MEPT is functional and ready for operation I'll remove the LCD (and its code from the sketch)

Step one

modify an old sketch & strip out un-needed code until I had a simple carrier generator
add function to vary the frequency in a stepped-ramp sequence to check operation
add functions to make dits and dahs and spaces of appropriate lengths
add function to send a callsign/message explicitly entered as a series of calls to dah(), dit() and space() and run it from loop()
add code to light an onboard LED during “key-down”
add code to show operating frequency and the letters of the callsign as they're sent on the LCD

I monitored the SI5351 output on my normal 30m grabber - there's enough radiation direct from the SI5351 board to make a trace on the waterfall.

}

Step Two

The next step will be to build a small TX PA to boost the SI5351 output up to around 1W and a LPF. I'll add a PTT line to key the PA, driven from the Arduino so that the sketch can have periods of carrier off between cycles if necessary. 1W should be enough power and should be simple enough to generate. I might have a go at a Class-E MOSFET amplifier.

Test Amp

I found a 30m PA strip from a previous project that produces about 6W from < 10mV drive, with 3 class-A bipolar driver stages feeding an IRF510 MOSFET - originally intended as a linear amplifier.

I've played with the supply volts and the MOSFET bias and can comfortably get up to 3W carrier with 8V supply. It's not terribly efficient but at QRP levels that's hardly relevant.

I've got it connected to the Ardiuno/Si5351 and it's on the air running 1W.

I'll use this amp as a blueprint for a new PA for the MEPT, perhaps with fewer stages as I don't need so much gain or linearity.

I've seen it on grabbers around Europe

Grabber results at 1W

At 1533z I reduced power to around 200mW

Grabber Results at 200mW

Stretch Goals

Add a function to generate “Slow FSK Hell” to make waterfall-readable text - see the image of GM4GHK below
Add DFCW
Add a “normal-speed CW ident” for cases where it might make sense (?)

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:
    Data:
        Version: 3 (0x2)
        Serial Number:
            39:72:44:3a:f9:22:b7:51:d7:d3:6c:10:dd:31:35:95

            Not Before: Mar 12 00:00:00 2019 GMT
            Not After : Dec 31 23:59:59 2028 GMT
        Subject: C = US, ST = New Jersey, L = Jersey City, O = The USERTRUST Network, CN = USERTrust RSA Certification Authority

or ca.pem.2

Certificate:
    Data:
        Version: 3 (0x2)
        Serial Number:
            7d:5b:51:26:b4:76:ba:11:db:74:16:0b:bc:53:0d:a7
        Signature Algorithm: sha384WithRSAEncryption
        Issuer: C = US, ST = New Jersey, L = Jersey City, O = The USERTRUST Network, CN = USERTrust RSA Certification Authority
        Validity
            Not Before: Nov  2 00:00:00 2018 GMT
            Not After : Dec 31 23:59:59 2030 GMT
        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
        Signature Algorithm: sha256WithRSAEncryption
        Issuer: C = US, O = DigiCert Inc, OU = www.digicert.com, CN = DigiCert Global Root G2
        Validity
            Not Before: Nov 27 12:46:40 2017 GMT
            Not After : Nov 27 12:46:40 2027 GMT
        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
