I set out to do this with an Arduino some years ago and built the hardware on a breadboard. I never got past decoding the FSK signal from my M102 though and gave up for whatever reason. I think I ordered a REX. 🙂
The idea was to store the decoded bits in a 1MB EEPROM connected to the Arduino's SPI interface. On Sat, Apr 3, 2021, 17:59 John R.
