[Elecraft] K3S audio and N1MM+

[Paul Wilton]

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.

I have connected the K3S via USB to my windows PC and with Audacity have proved that I can receive audio over the USB connection using the built-in soundcard in the K3S.  However, I cannot make it go in the other direction - ie get the K3S USB soundcard to modulate the output.

When I ask N1MM+ to transmit audio, then the K3S goes into TX.  However, I cannot heard the computer generated audio in my headset - all I can hear is my own breathing into the headset mic (hence proving that that the monitor function works).  Also, no RF is going out.  MAIN:MIC is set to RP, MAIN:MIC+LIN is set to ON.
