I'll discuss this with Lyle, KK7P (our DSP engineer). I don't think 
this has anything to do with "desensing" if a narrow filter is being 
used. I can't imaging what might cause it with lower-level signals. The 
ADC has plenty of resolution, and the DSP has plenty of horsepower, so 
there should be no difficulty in separating out multiple stations in 
close proximity.

There are only two things I can think of: the AGC may be set too 
"flat", or, if a speaker is being used at moderate to high output, that 
perhaps the RFC47 mod hasn't been done (on the RF board). In any case, 
we'll look into it.

tnx
