I have a Collins Mechanical Filter F455-FB-21 (6W2) - it looks new.
Can anyone tell me what radio this was used in? What bandwidth is the filter?
I presume it is a 455 kHz filter.
Does anyone have any idea what this filter is worth? I have two crystals with it so presumably
it i was used as an SSB generator, or they were used as BFO crystals. 453.58 kc. and
Thanks for any helpful ideas.
