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