[CQ-Contest] Audio limiter/controller

[Tom Hellem]

Mark-
I have noticed the same thing on my K-3. Like you I have fiddled with the AGC adjustments but without much improvement. I have always understood that the purpose of the AGC circuitry is to prevent the condition you described. I am getting the feeling it is a design flaw in the rig. I have not done it yet but my next move is going to be contacting Elecraft and see what they say. I think they're pretty responsive so hoping we can get to the bottom of it that way. It might also be useful to poke around on the K3 reflectors. I would guess others have had the same experience.
