There are two AGC parameters that should help.
1) AGC THR
This sets the signal strength which must occur before AGC is activated.
It is defaulted to the several microvolts range. If you are listening
on a quiet band with a gain turned up, you might have 20 or 30 dB of
signal range before AGC starts. Set AGC THR to a lower value. Based on
your comments, I suggest a value of 1 or perhaps 2.
CONFIG:AGC THR 001
(default is 5)
2) AGC SLP
Once AGC is activated, this determines how much louder strong signals
may sound than signals just at the AGC threshold. 15 will really
flatten the response.
CONFIG:AGC SLP 015
(default is 10)
I suspect if you adjust both of these parameters - and AGC is ON! - you
will be happier with the K3 in your particular operating environment.
