I’m a bit confused what the purpose of using gtk is beyond the graphical scope etc interface. It’s not pretty but it works….
Using external measurement is fine for TX level adjustment but for RX level you need to see the waveform coming in to soundmodem to make sure the audio isn’t over or under driven.
