[Milsurplus] GO-9, AT-12, and such

[wf2u at ws19ops.com]

Hue,

The Canadian RCA-built AT-12 was simply a commercial product  
"recruited" for military use as it was a proven, reliable and fairly  
sturdy piece of equipment.
Similar in the procurement concept of the Bendix commercial aircraft  
radio product line which was also used by the Canadians.
My logic says that it made a lot of sense as far as the Canadian  
procurement was concerned, as there was personnel already familiar  
with the equipment from the airline industry, the US manufacturers  
were busy procuring materiel for US use, the British barely had enough  
for their own use. So instead of developing new equipment for military  
use only, the fairly recent and relatively - for the state of the  
technology then - modern commercial equipment made sense for  
procurement for the military.
I believe the concept is almost similar to the radio equipment in the  
Royal Canadian Navy in WW2. They started the war with 30 ships,  
finished with over 300.
The main Navy radio supplier, Canadian Marconi Corporation turned out  
equipment which was more advanced than the 30's design of radio  
equipment used in the British and US navies, as they had to start  
practically from scratch.

As far as I know and saw radio compartment photos, later, post  
GO-9/RU-19 equipped PBY's had the ATC aka ART-13/RAX setup, and not  
the BC-348, that receiver if you recall is not Navy. Of course even  
later, post WW2 it was the ART-13/ARR-15 in the Navy.
