Comment,s 1) The Canadian Marconi marketing brochure does not mention a  receiver. It is assumed that the TR-15PS requires an external receiver.
2) The marketing brochure for this radio was found  at Library and Archives Canada in the RCMP file #RG12 Volume 113. In the 1930s, the Department of Transport handled the purchasing of equipment for the RCMP so that's  why the brochure was found there. The transmitter was most liekely used in RCMP patrol cars.
