[AMRadio] RCA AR-77 or RCAF GR-10 Receiver

Hi Dave,

I've seen a couple of these Royal Canadian Air Force versions of the AR-77
at Hamfests some years ago...back around the early 70's, QST used to
advertise some surplus outfit that had a quantity of them for sale (I could
never find the ad again after I got an AR-77 of my own in the early 90's ---
sold it it in 2000).

The military versions did NOT have the chrome dressing --- likewise, they
were a monotone colour..."RCAF blue", as I recall. I never did check the
calibration of the bandspread dials of those Hamfest receivers, & I wonder
to this day if the RCAF units had expanded AMATEUR radio bands, or some
other set of frequencies...?

Good luck finding a parts unit! Both versions of the receiver are pretty
rare in these parts, & the few that do turn up (years ago!) are pretty
rough. I liked the calibrated bandspread feature of mine, & the adjustable
crystal filter, but it suffered terribly from images on the high
frequencies, & the front-end tended to "take off" up in the higher regions
of the frequency range.

The full-page ads for it --- around 1940-41 in QST --- make for interesting
reading. One VERY rare option for it was a HUGE bass-reflex loudspeaker
assembly. Most impressive.

I'll wager that more than a few of these oldtimers still languish in
forgotten basement & attic locations of OT's who may well have themselves
forgotten they still have one in their possession! That's how long they've
been around...

Good luck in your search...persistance CAN pay off!
