WIRELESS SET (CANADIAN) No. 19 MK.III
Year 1942

Wireless Set, Canadian, No.19 MK. III has been designed primarily to provide a complete and reliable system of communications in Armoured Formations. It is not restricted to use in Armoured Formations, but may also be used in Armoured Fighting Vehicles (AFV), in various Wireless Trucks and as a Ground Station. The st provides the following communication facilities:- (i) The A-Set for long range communication (ii) The B-Set for short range communication (iii) The I.C. Amplifier for intercommunication within the vehicle. Unlike the No. 19 Mk. II , it is possible on the Mk. III to switch-off the sets not in use. Since it is no longer necessary to heat the A-Set valves in order to operate the B-Set or I.C. Amplifier, the MK. III is more economical in battery consumption.
