LINE OUT from the K3 includes Tx audio.  LINE IN goes to Tx audio. If 
the computer has any path between LINE IN and LINT OUT, you'll get 
feedback when you go to transmit.

You have the MIC ON and MIC gain non-zero, so the K3 is using the MIC. 
Hence the feedback.

MIC+LIN means "Mic and line simultaneously".
