OK, I brought this up before, and was specifically told that "low RF
gain and high AF gain," as is traditional in analog radios, does not
apply to the O2.
Personally, I like to leave the RF gain at 100, then use the AGC
threshold as my RF gain, and then touch it up with the attenuator.

I'm beginning to feel like a broken record on this subject...
Turn the AGC off... Turn off the NB, etc... Get rid of all the 'cover up'
processing crap as it only adds distortion to the mix...
Go to the 300 cycle roofing filter...
Turn the RF gain down until you don't hear anything...
Turn the audio gain relatively high - lots of hiss...
Now advance the RF gain until you hear signals...
Ride the RF gain as your audio gain...
You should be able to separate the signals in the pile...
Now, there will be times when the DX is so mixed with other signals, 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..
