Solution Thanks for the help either on the reflector or direct. I found the problem in the end. This was brand new K3S I was setting up. Since I wanted to use N1MM+ as voice keyer, I had never run it with MAIN:MIC set to Line. Hence the “mic gain” for the LINE input was set to zero. Changing MAIN:MIC to Line first, increasing the gain so that the audio was working and then going back to MAIN:MIC to RP (with MAIN:MIC+LIN ON) worked.
