Experimenting with ThumbDV and analog radio

Did some experiments with the ThumbDV or AMBE3000 and an analog radio. Very funny to experiment with. Sound is pretty good if you stay in range.

Working now on experimental DSTAR control via analog DTMF. e.g. (DTMF) B7602 = XRF076 B

I used a DRA818, but it is better to use the DATA port of a radio like Yaesu or ICOM. The DRA818 is a very cheap radio so do not expect high quality sound.

I used:

Commands DRA818:


  • USB soundcard or internal sound card of my PC
  • Wouxun analog radio
  • CH340 serial TTL ( connected CTS and RTC for controlling the DRA818 ) ( TinyTronics Netherlands )
