[TenTec] Intermittent Omni VI RX Falloff (Art Trampler)

I had the same problem on my Omni-VI and fixed it by removing and  
re-installing the crystal filters.

Hey All,



On  my Omni VI Opt 3, the RX periodically drops off 20 to 25db, using  a
6db/S-unit scale.  If I wiggle the RF gain it can pop back, or if I go  key
down for one ?dih.?  I haven?t tried simply closing the PTT to  restore (as
opposed to any transmission) but I think that would also do  it.



I?d think ?Relay? or ?Diodes? if it only popped back with  closing the
PTT/sending; I?d think bad solder joint if it was only the RF  gain.  What?s
interesting is that the RX is not lost, just  significantly
reduced/attenuated.



Your  thoughts?



Thanks,
Art
