Experts on the TT reflector:

I have two OmniVIs, both upgraded to option 3. The first I have had for some 
time
and it apparently has an early S/N (1A10533) while the 2nd one is newer 
(40A10...).
The older one will 'fold up' on signals within 5 kHz or so that are "20over S9" 
strength.
Pushing the attenuator cleans it right up, of course.  I didn't know that 
wasn't normal
until I got the newer rig. It is rock solid to 40 over S9.  As a trip to 
Sevierville is both 
expensive for shipping and  possible rig damage in-transit, I am asking the 
collected 
experts if there is something obvious I should check for a possible home repair 
effort.  
The only time this affects me in practice is with some big stateside signals 
when DXing
on 40CW to Asia in the morning: K7XB will consistently overload the older rig 
from
his SLC QTH!!  I haven't noticed it on the other bands yet. BTW: the above 
narrative 
assumes CW, of course, and folding up  means the signal itself sounds poor and  
so 
does everything around it.
