(Google is your friend, I typed "AGC K3")

AGC definitely helps to some extent as well as working with the
passband as needed for really noisy situations.

I think a lot of folks on this list use the default settings which are
ABSOLUTELY fine but in some instances sub-optimal.  I know playing
with my AGC did help.

My biggest complaint with the NR feature on the K3 (If Eric/Wayne and
friends care about my 0.2 cents), is that so far, the various
different algorithms have not been that helpful.  Though we have a lot
of choices with the DSP, I find most of them a complete waste at least
on sideband.  I typically use F1-1 (default) or F2-1.

I do wish there was more of an explanation on the different NR
algorithms employed than what's in the manual (plays music for
Elecraft to chime in...) ,i.e.  what are the differences with respect
to the DSP, a general guideline/recommendation on what to try during
certain situations....etc.
