Mike, I had the same thing happen to me. Unfortunately, I didn't read your post in time to respond. The K3 audio menu settings are per mode. 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.
