Bill,
The R-278, part of the GRC-27, if my memory serves me. The GRC-27
consists of a transmitter, receiver, and modulator/power supply in a
large vertical cabinet. It weighs a ton... or more.. hi! The receiver
is neither rare nor desirable, per se. The receiver is of the older ilk
of UHF military receivers. It only has 100kHz channel spacing from
225-399.0MHz. The later equipment has channel spacing of either 50kHz
or (as the current eqpt does)25kHz spacing. I suppose if one were to be
resurrecting a mobile control tower or the like, one might want one of
these. Again, though, its only one part of the actual radio set.
That's my take on it. Having said the above, I had one "on the air" a
number of years ago that I got from the AF MARS program. It was
impressive to demo it to friends but that's about all. I would imagine,
however, that the "compleat collector" would need to have one of these!
