Recently used an Orion II (on CW), receiving on bands crowded with many very 
strong CW signals (and a fairly large antenna). I noticed sometimes a condition 
where the receiver seemed to momentarily lose sensitivity (when listening to a 
rather weak intended signal) at the symbol rate of a stronger signal just 
outside the DSP passband, as if whenever the strong out-of-passband signal was 
present, in-passband gain would decrease. This was significant enough to affect 
my ability to read CW from the intended (weak) station. Is there a name for 
this artifact? Can it be controlled by proper adjustment of the receiver (I was 
using the receiver at full RF gain, no attenuation, no preamp enabled.) Sorry 
if this has been discussed before (or discussed to death) as I don't read the 
reflector digest regularly.

Thanks,

Dave
