Well, I have a hard time to give you proper advice without more details but... why not start by setting the demod flat, reduce the gain (run the 20db attenuator) and adjust your audio levels from there and see what you get... / adjust on findings & let us know where you are USBRADIO/SIMPLEUSB deemphasis = no ; enable de-emphasis (input from discriminator) txboost = 0 rxboost = 0 ; 0 = 20db attenuator inserted, 1= 20db attenuator removed ; Set to 1 for additonal gain if using a low-level receiver output rxdemod=flat txprelim=yes txlimonly=no Tune rx audio levels from this point for a start. Test the rx to decode dtmf , adjust tx afterwards. My method here is not the best, but you got to start somewhere. I may not have thought of everything either. There is audio tuning software build-in to the current code but I have never used it to advise. ...mike/kb8jnm On 6/1/2018 5:42 PM, Bob Pyke wrote:

does the volume change in app_rpt when you adjust the volume control on the radio ?

The MASTR II has a TS-32, and the audio comes from “audio filter output” on the TS-32, which is driven by the MASTR II “VOL SQ HI” and from there is where it gets messy, as there appear to be errors in the schematic which indicates it is wired to the PTT, in one part of the schematic, and “SPkR H” in another part. I think they have some pi numbers miss labeled in the schematic.

Are you using discriminator audio, line audio or speaker audio ?

Is there a way to “select” something in between in software?
