This Rockwell Collins KWM-380 / HF-380 Original NOS Matching Set of 2, First IF Crystal Filters (On the Receiver / Exciter Board) is P/N 293-1332-010
Not many know about this filter in the KWM-380 and HF-380 Transceivers.
This Crystal Filter set of 2, is located under the shielded part of the receiver/ exciter board.
They essentially act as a roofing filter with steeper skirts that an LC circuit could provide.
The filter requires a "matched" set of two, in order to keep the attenuation to a minimum.
If one crystal in this filter set fails, you need to replace with a matched set.
There is no other source for these and if one would fail, your rig basically becomes a door stop.
I have only a few sets left!
