[Milsurplus] collins mechanical filter/bandpass info needed

[John Kolb]

That's a F455Z-24C.  I don't have the specs on the -070 variation,
but it should be very similiar to the 526-9666-010.

LSB filter 455.0 kHz carrier freq
2.85 kHz min BW at 3 db, 3.1 kHz typical
4.9 kHz max at 60 db, 4.1 kHz typical
5 db insersion loss
2000 ohms in/out impedance

Here's a plotted response curve from one
