[TenTec] ORION II CW pile up readability

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.

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..
