This has been an interesting discussion alright.
I have spent quite a bit of time experimenting with different settings
of af gain/rf gain/agc using an Orion II with latest firmware.
My observations have been that the difference in readability of a weak
cw dx station has for me been minimal by increasing af gain and riding
the rf gain regardless of agc settings.
It does not seem to alter the s/n ratio between the weak cw station and
the atmospheric noise much at all, if any.
Perhaps this is because I am using a vertical antenna that may be more
noise susceptible?
The difficulty I have with minimal agc and high af/low rf gain is that
as soon as the dx station signs, a very strong station calls and just
about blasts me across the room before I can get the rf gain down.
Advice please?
Tnx & 73,
Wayne
