Yes, the No. 1 set is a large heavy bit of kit. But at that time, it was no different to other types of mobile radio technology.

re: the pic. I like the heating arrangement and the logo ! Could do with that here ATM. Been below 0 C at night - I can see some snow in the distance, on the top of the local range , ski field ....

Some more pics from pre-war and early wartime Canada. The Ford car appears to be a standard roadster model, straight out of the showroom , but it was finished in army livery. A unusual choice for a army vehicle considering the limited carrying capacity.

A nice 36 Ford tourer .... with improvised antenna mount.

Description
A circa 1940 photo featuring two vehicles.

The first is a 1936 Ford Phaeton outfitted for wireless. "A" Squadron Royal Canadian Dragoons had two such vehicles, the Lord Strathcona's Horse had three and the Fort Garry Horse had one.
The second vehicle is a cab-11 8-cwt Canadian Military Pattern truck.
This photo date isn't known however the first vehicle has a 1940 Quebec license plate. In 1940 it's likely that the vehicles were outfitted with a Wireless Set No. 11 but when they were acquired in 1936 it would have been a Wireless Set No. 1.
