[Elecraft] K3 Monitor feedback

[Mike]

Hmmm..

Any voice mode (I don't have FM) I get feedback with MIC+LIN on. Muting 
the Line setting in WIndoze (Mine doesn't say whether it's in or out) 
kills the feedback. Pulling the line-in or line-out doesn't kill the 
feedback.

If the ProSet is laying on top of the rig, there is feedback at all 
settings until I move it. Vox is off, so that indicates that the mic is 
open all the time. Verified that by putting my hand around the mic, 
cupped toward the K3 from a couple of feet away, 
*SQUEEEEEEEEEEEEEELLLLLLLLL*.

I don't understand the audio path, but ti me it seems like a flaw somewhere.

If I didn't like RTTY so much, I could just set MIC+LIN off, and be happy.

When I switched to AM, I had the rear panel mic enabled and the MIC+LIN turned ON. When I turned MIC+LIN OFF the feedback went away. The operation of this menu function wasn't exactly clear to me so I had set it up the way I thought it should be for all modes (SSB, AM, PSK and FSK). I was wrong.
