[Elecraft] K3 Problem

[Dick, WN3R]

I actually sent my rig back for this problem, but I didn't analyze 
properly so it came back to me with "no problem found".  I now 
understand where my distortion is coming from.

With compression above 30, I seem to be getting some RF feedback when 
MIC+LIN is ON.  When it is OFF, audio is clean.  Thinking RF was being 
picked up by a cable, I removed them all.

It made no difference. In the TEST mode, tx audio is clean.

I am anxious to get this fixed before the contest so I can use voice 
recordings in N1MM.

Thanks
