RCAF RCA ATR-11 Transceiver

[David Dunlop]

Anyone familiar with this airborne wireless set? A friend has run across one in it's wooden transit chest but information regarding it is next to non-existent it seems.

A series of ATR-1 to ATR-7 radios were apparently built for the RCAF in the early part of the war by Canadian Marconi. This ATR-11 was built in 1940's by RCA's Montreal facility.

The only thing we can find so far on the internet is several RCAF Harvard sites documenting these training aircraft. Quite a number of the RCAF postwar Harvard fleet surplussed out in the 1960's appear with a notation the aircraft in question was upgraded to an ATR-11 radio system sometime post war.

We are trying to wrap our heads around why a radio designed and built in the first half of the war would have been a preferred upgrade to Harvard Mk IV's after the war.
