You can adjust this acg response if you want flatter ,  refer to manual
and adjust to personal taste from flat (limiting ) like to the icom 7800
to very rounded Like some k2's 
there is a lot of control over how the AGC works

What problem, explain please?

have you tried calibrating the PLL?

 select lo-hi cut and adjust, it's fine, I regularly use 1.8 or less on
SSB here

use high and low cut on the filters, perhaps Taylor the RX EQ to suit
your ears.

noise noise reduction, in DSP can not, (no mater what code is used)
deliver the impossible and render readable an SSB sig that is brueid in
the noise. the K3 noise reduction is the best I have heard on any radio
to date but I still prefer it off most of the time and let the brain do
it

NO Fix please! the delay is right for me ! 


I came to the K3 from the Icom 7800, the 7800 is for sale I know which
one I prefer to listen to.
