When you are in a QSO with one or more stations, and if they are at least a
little louder than the background noise or QRM, it is useful to turn the RF
gain control down somewhat so that the noise doesn't come up quite so loud
between words or CW characters. This reduces fatigue.
Automatic gain controls try to maintain a very constant volume level of the
received signal and noise, although they can very in their decay (recovery)
time constants. Some receives have a "sloped AGC" setting which only
partially compensates for changes in signal level; using this function would
be a lot like reducing the RF gain setting.

Brings up a good question:
When wouldn't someone want the RF gain all the way up?
I usually just leave it turned on full.

Well I have been a ham for 46 years and have never ever been so embarrased!
I never never touch the rf gain control but indeed it got turned all the wa=
y down.
Maybe it was the cat.
Unbelievagle!
Must have grabbed it by mistake thinking I adjusted the squelch.
Holy S$$t.
Thanks Steve you saved my bacon.
Crawling back in to my hole for a long time.
