The majority of the time, the DX station is not far off the noise
floor. If they are, then the RF gain becomes useful, otherwise I leave
it alone.
I recently tried turning the AGC off in DATA A mode. If you're trying
to capture the entire audio bandwidth, it helps, a lot. A strong signal
no longer swamps the weaker signals. This is for 'sweep' mode only, but
I don't bother to switch it in for working DX. It follows my concept of
never allowing AGC to kick in for the best data decoding (least is
best). For low level signals, it seems to work better and is certainly
worth a try.
Then I narrow the filtering down to only the desired station per usual,
clone the other VFO, offset split according to the DX instructions and
make the contact. Pretty durned simple and easy. The only thing it's
hard on is the ears, the sudden LOUDness of the band can be jolting when
you switch to DATA A.
