Ron and all,
Are you aware that reducing the RF gain will reduce the AGC action as well.
Folks who want to try it may be surprised how well copy can be made under
QRM conditions with the AF gain at full and the overall gain controlled by
the RF gain.
With this technique, the residual AGC provides some 'limiting' protection
for the ears while allowing one to dig for really weak signals - this is
applicable at any bandwidth, but more so for wider ones.

To this day I still prefer a wide filter, even with moderate QRM. With my K2
on CW, I use the SSB filter more than any other. I love being able to keep
track of what's going on around the frequency I'm using. The trick of
course, is to turn off the AGC so stronger signals in the passband won't
depress the receiver gain. One of these days I'll add a hard limiter to
protect my ears. The dynamic range of the K2 allows really huge peaks to
come through without the AGC.
