Followed INRAD instrux re making adjustments after filter installation; filter
passband seems centered around 200 Hz, way low, so low that at first, I thought
it wasn't working at all.
Haven't tried re-installing the stock 600Hz filter, yet.
INRAD sez they never heard of this syndrome; indicated Yaesu may be helpful.
Been staring at my facservmanual block diagrams and schematics for ideas, so
far to no avail . . . any help out there, please?
