[Elecraft] K3S audio and N1MM+

[Don Wilhelm]

Paul,

Where are the software soundcard sliders for the K3 USB CODEC set in 
your computer.
They normally will be at 75% or more.

Do you have anything plugged into the LINE-IN jack on the back of the 
K3.  If so, that over-rides the audio from the USB CODEC. Remove the 
Line-In plug.

73,

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.
