 And with a few warnings it builds!
+Reprogramming needs a STM programmer like this [[https://www.aliexpress.com/item/FREE-SHIPPING-ST-Link-V2-stlink-mini-STM8STM32-STLINK-simulator-download-programming-With-Cover/1823628996.html|one from china]], or if you can't wait that long, [[https://www.amazon.co.uk/gp/product/B0722WMDFQ/|this one]] on Prime from Amazon.  The driver for the ST-link-V2 programmer is here [[https://www.st.com/en/development-tools/stsw-link009.html]].  I used the ST-Link utility programming tool (which includes the driver) from [[https://my.st.com/content/my_st_com/en/products/development-tools/software-development-tools/stm32-software-development-tools/stm32-programmers/stsw-link004.license=1533224576969.html|here]].
+Pinout of the SG41 2mm connector is [[https://github.com/Qyon/STM32_RTTY/blob/master/docs/pinout_extension_port.txt|here]].
+Connections to the 2mm pitch RS41-SG connector I made were:
+  * Gnd to Gnd
+  * +VDD_MCU to +3.3v
+  * SWCLK to SWCLK
+  * SWDIO to SWDIO
+  * Rst to Rst
+Be aware that some of the circuit diagrams around are for the OEM ST-Link V2 programmer which has many more pins than the cheap one I link to above.
+And we have a connection using the ST-Link utility.
+<code>
+:51:09 : ST-LINK SN : 56FF6B064977535412210687
+:51:09 : ST-LINK Firmware version : V2J29S7
+:51:09 : Connected via SWD.
+:51:09 : SWD Frequency = 4,0 MHz.
+:51:09 : Connection mode : Normal.
+:51:09 : Debug in Low Power mode enabled.
+:51:09 : Device ID:0x420
+:51:09 : Device family :STM32F100xx Low/Medium density Value Line
+:51:09 : Can not read memory!
+                  Disable Read Out Protection and retry.
+</code>
+I then tried for several hours to re-programme the chip, and kept failing, before discovering that I needed to turn off the 'Read Out Protection' that was turned on in the chip.  I used the STM32 ST-Link utility to do that, connecting to the RS41 (Target -> Connect) and then editing the Options Bytes (Target -> Options Bytes) to disabled Read Out Protection and 'Unselect all' in the bottom 'Flash sectors protection' section.
+<code>
+:51:19 : Option bytes updated successfully.
+:51:31 : Flash memory erased.
+:52:01 : Memory programmed in 6s and 812ms.
+</code>
+Now both the ST-Link and the CooCox CoIDE tools will both flash the chip
 The RS41 takes 2 x AA batteries - as you look at the battery holder vertically, with the aerial down and temperature sensor up, the right hand battery has + at the top, the left hand battery has + at the bottom.
+I have tried all of the software above, but currently am running darksidelemm's and getting packets transmitted:
+$$$$$G7PMO-RS41-1,18,17:03:20,N52.3227,W0.7062,93,0,4,2810,25*9511
+Hopefully this is of use to others - any corrections please do let me know.
+Cheers,
