[MRCA] What is this? SCR-522

[scottjohnson1 at cox.net]

It would seem the whole VHF "system", including the 100-156 frequency range,
was the brainchild of RAF fighter command.

Bendix built the Lion's share of the BC-639, BC-640, and SCR-522 equipment
for the allies, All of mine has dual badging, i.e., red air ministry plates
and black US signal corps plates.

I have bot a working BC-640 and 640A, as well as working SCR-522s.  It was
primitive, and better equipment followed along in the form of the ARC-1 and
ARC3/36/49 (Which served until the early sentries, at least !)

But- It was there when it was needed and performed splendidly compared to HF
interplane and the earlier pipsqueak British fighter sets. And of course,
the postwar VHF comm spectrum was narrowed to 116-136 MHz in the US, While
internationally it extended up to 150 MHz.

Don't sell that radio short! The SCR-522 is a radio with huge limitations,
insensitive, the auto channel mechanism was larger than the radio and all
the difficulties trying to get the multi overtone crystal to work for the
front end. But all that aside it was king in the ETO and just about
everywhere by the end of the war being VHF AM was where the world was going.
I prefer American hardware like the ARC-1 or better yet the ARC-3 that came
after, the ARC-3 stayed in service well into the sixties but the
cantankerous old SCR-522 with all its problems set the standard for
everything that came after.

 

Hard to Imagin anyone would attempt to do something like a P-51 for a museum
without that radio.
