Basically this corrects the transmit (TX) and receive (RX) frequency of the board, if they’re not on frequency. This is the BER 0.4% when no setting RX/TX offset. 240 -120. 94 -125. 50 -130. The STM32-DVM-MTR2K will saturate the MMDVM ADC input at signals much stronger than -30dBm. That's ok, I did that on purpose in order to keep the signal level at the low end up a little higher in order to improve ADC resolution for weaker signals.

Now when I put everything into repeater mode. The radio decodes nothing voice wise. All my commercial gear, and secondary GD77 with stock firmware running, has no ...GB7WR is a homebrew MMDVM repeater based on the Pi-Star image on a Raspberry PI 4. It runs a Motorola GM300 on transmit and receiving with a Motorola GM340. The coverage south of the M50 is limited and does not match the propagation map. This appears to be due to some high buildings in that direction.
