The R-278B/GR is a heavy tube type receiver that was used in military
air traffic control towers. Beside its today's uselessness, in my
opinion it equals R-390A in quality and workmanship.

A local junk dealer in Baltimore had 3 more or less complete GRC-27's
for $100 each. I think someone bought them for export, but for what
purpose? The problem with that equipment is that it does not have the
requisite number of UHF channels that would support current military
use, even in the 3rd world. And... they are heavy... aren't they.

They are heavy. I don't think it would be all that hard to convert them
to the new channel spacing (using a half-channel switch and reducing the
bandwidth), but I don't think anybody would want to, seeing how cheap
the modern UHF stuff is. And the military guys everywhere are trying to
get away from AM even for local ops stuff.
