I'm trying to identify the filters installed in the 9MHz IF of my
OMNI VI+. The only clues seem to be the crystal frequencies marked on
the top of the crystals. There are 3 filter installed:
1. I suspect this is the factory installed SSB filter: marked 48058
on one end, 9634 on the other
2. Marked 8726 on one end, 48037 on the other
3. Marked 48036 on one end, 9630 on the other.
