For reference, here are my preferred AGC and other settings for contesting with
a K3 and large CW pileups.
Bob's a great op, so I really appreciate seeing his settings. But
they're all run together in his email with no paragraphs or punctuation,
so it's very hard to read. I copied his settings into a word processor
and added paragraphs.

First, set *CONFIG:TECH MD ON* to un-hide some AGC settings.Set
CONFIG:TECH MD OFF when finished, to eliminate distracting values from
accidentally appearing in the SubRx display (PLL1, AFV, dBV, etc.)
*AF GAIN LO* -- Cuts audio hiss.May not work with all headphones.OK on Heil.
*AF LIM 20* -- Only takes effect when AGC is OFF (rarely used)
*AGC DCY Soft* -- Reduces AGC-induced IMD, recommended for pileups
*AGC HLD 0.05* -- Slow AGC hold time (50 ms).Reduces AGC-induced IMD,
recommended for pileups.Works with AGC-S only, no affect when using AGC-F.
*AGC PLS NOR* -- Loud static pulses do not pump AGC
*AGC SLP 010*-- A pretty "flat" AGC response curve.I may move this lower
since pileups of loud guys can blend together, but I like this setting
because it saves my ears.
*AGC THR 010* -- AGC kicks in at about S-8.Signals lower than THR behave
as they would with AGC OFF ( +1 dB of RF = +1 dB of audio)
*AGC -F 120* -- Factory default fast AGC decay rate (recovery
time).Higher = faster.Faster can be bad.
*AGC –S 20*-- Factory default slow AGC decay rate (recovery time).Higher
= faster.Faster can be bad.
*RF GAIN at 3 O'Clock or less* except when all signals and band noise
are very low (e.g. 10m)
*AF GAIN* never higher than 3 O'Clock
*AFX OFF*
*NR OFF*
*NB OFF*
*RIT OFF*
*XIT OFF*
FL1 to FL5 BW set to match labeled filter bandwidth exactly, not wider
or narrower.
Use *AGC-F* or *AGC-S* for CW, whatever works best for you.
Use *AGC-S* for SSB.
CW Pitch 500 (or to taste), IF shift centered (on CW)
500 Hz InRad 8-pole filter on CW
2.8 kHz 8-pole filter on SSB (1.8 8-pole when bands crowded, *must move
IF SHIFT lower for pleasing audio*)
Use *XFIL* button to toggle between filters and reset the IF shift,
rather than NOR (hold) button
*PREamp ON* for 15m and up, *PREamp OFF* for all other bands
