I came across one of these panadaptors. Its almost identical
to the Army version (BC-1032 ?), but this one has an IF
of 400 KC +/- 50KC. Does anyone have any idea what
receiver(s) it was used with? I'll probably try to convert
it to a 455KC IF so its usuable with receivers I have, but
before doing that I'd like to get some more info about it.
TIA.

The RBB and RBC use 400kHz for the IF, and they had optional outputs
for a panadaptor, so I'm fairly sure they were meant for each other.

I wouldn't modify it.
