[Elecraft] AGC INFORMATION

[Matt Murphy]

Louis,

FWIW I like my K3 noisy, almost so it sounds like there is no AGC action,
just enough to protect my ears from an unexpected loud signal. I've found
that this makes it easiest to copy extremely weak CW signals that are below
the noise, and prevents static pops from covering up the signal.  The two
settings to adjust are AGC threshold and AGC slope.  Start with threshold
as it will make the biggest difference in how strong vs weak signals
sound.  If you need finer-grained control, the AGC threshold can be useful.
The other settings should be fine at their default values. The AGC decay
"soft" setting is preferred by some in pileups, so you might try both
settings.

I found this writeup which looks pretty good:
