Inject an audio signal from your soundcard or ? into the lINE IN and see 
if you get Tx audio with MIC SEL set to LINE IN.  The level isn't 
important (keep it under a volt RMS to be safe), you are looking for 
functionality not fidelity at this point.

If so, and if the radio was a kit, it is very possible that the 5-pin 
connector between the DSP and the FP boards is misaligned.  As many 
times as I've had my K3 (and other people's K3s) apart, I made this 
mistake again today.  So I know it is easy to do!

This requires pulling the front panel off and inspecting, then removing 
the DSP board and refitting it if the problem is confirmed.
But it's easier to inject a signal than to tear the radio apart!
