My Omni 6+ has gone hard of hearing. The signal loss has been traced to the
pbt board. When I inject a 9mhz signal to the input of the board, I see about a
6 s unit difference between it and a good one. We have swapped out the 2.4khz
filter with no change. We have also done the bpt adjustments and peaked the 3
output coils. I'm suspecting Q9, the second mixer maybe the problem. Anybody
have any experience with this board?
Tnx, Ernie K2EP
