The procedure as you outlined it essentail turns off AGC and puts you in a
completely manual AGC mode. This is how my old Collins 75A1 (circa 1949)
has to be run to listen to SSB and CW. I would not want to use a receiver
with manual gain again. The AGC slope feature was added to solve this. You
can set it up to make weaker signals have less volume. This setting in in
the RX menu.

buckshot, amp slop, white noise, and qrn, that you cannot copy them.. This
is not solvable with todays technology - but I find the O2 to far exceed the
1000D, MKV, Omni, etc. in this high noise environment so for the moment it
is the best answer..
