Gang,
Got a very nice 75A-3 on a swap a few weeks ago and am
still looking for a second narrow bw mechanical filter. I
have learned that there are all sorts of Collins mecahnical
filters out there... just need one to fit the 75A-3. One
set of numbers should be F455 B something-or-other, with last
number indicating bandwidth, or so it seems. Problem is
running into the Collins parts numbers without any cross-reference
from Collins part numbers to the filter that would fit.
So far have figured that Collins part number 526 xxxx xxx
is a mechanical filter, and the last three indicating (I think)
the filter bandwidth. What I need is the Collins part number
for filters that will fit the 75A-3 (looking for narrow - CW -
filter). How does a 526-9764-020 pan out? right IF (455) and
bw (200 cps) (I think) - but would it fit?
Or if someone has one they want to part with....
TIA,
73, Al N5AIT
