Hi Jeep - fun stuff! Finding the batteries in USAF "Stock" in those days is interesting!  Whatszis for?  LOL
I used to work for Motorola Communications in Schaumberg Ill (1970's) and there was a BC-611 proudly displayed in a glass case in the lobby of the manufacturing plant.  Even then, employees marvelled at it...
The standing joke was:   "Joe ain't old but he aligned that set in 1942..."

For whatever value, in the late 50's, CAP had a lot of 611's on 5500 kHz. Not sure where that frequency came from but there they were.  VHF was fairly scarce in those days, so the 611's were good for close in usage. As cadets, we'd take them out and see what they were good for, range wise. In suburban or wooded areas, we maybe got a mile... maybe.  In about 1960, the AF and the FCC denied the frequency as it was an aero assigned frequency. We turned them all in to go I have no idea. I remember the Burgess XX-69 B+ battery was expensive. We had a few of the D-cell dual adaptors.  In 1962, I drew a pair from MARS while at Keesler AFB.  Found the XX-69 (BA?) in bench stock. Nobody had any idea what they were for so, I got 10 of them. I recall selling mine, and the test jig, in about 1968, via the Yellow Sheets.  Also, concur with others that troops in WW2 really depended on the BC-1000 SCR-300 radios. But, Motorola's predecessor Gavin (?) nonetheless did a nice job with the 611 radio.
