This RCA film, “Radio At War”, has probably been already mentioned umpteen times, but i just viewed it myself.

https://www.youtube.com/watch?v=WUx_hqwHM1I

I saw RCA AR-77 receiver; TBY transceiver; SCR-610 radio in Jeep;  BC-375 ? transmitter in wood chest; SCR-178 in wood chest in forest with handcrank

generator; BC-611 handie-talkie; Navy large console with RAS HRO-type receiver at left ( i do NOT believe aircraft carrier installation ); RCA AR-60 receiver,

SCR-284 ( BC-654 ) on beach. Also carrier takeoff films of SBD ( “Slow But Deadly” or “Speedy D” ) warplanes.

I noticed, from the cut of the American troops, this was filmed long before the obesity virus escaped from Wuhan.
