Check the manual for the AF LIM function. It will do exactly what you want.

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.

What do people do to limit the audio output from their transceiver during
CW contest operations to prevent hearing damage when extremely strong
signals "pop up" unexpectedly? I have an K3s and have tried to adjust the
AGC settings without success. Is there any other adjustment in the
transceiver or has anyone used an external audio limiter device between the
output of the rig and the headphones? If so, which unit works best?

I want to preserve what hearing I still have left after 59 years of
contesting!
