Actually, there is not much to it, it is a notch filter based on the principle of "Q multiplier". This is a method where positive feedback is used to narrow-up the IF stage passband in a radio receiver. If you google "Q multiplier principle" you should be able to find a lot of information about it. Cheers.
This is what we used in Vietnam at the MARS station. Qui Nhon.
Were they ever used "in the field" for military operations?
Beautiful! You get ALL the neat toys! :)
..... Impressive gear!
