History / Summary

This particular piece of the wireless set No 19 (WS19) Mk II (Aust) connects the control unit to the radio. The complete radio was a
type fitted to 1939-1945 Australian vehicles and Armoured Fighting Vehicles (AFVs) such as Dingo and Australian Cruiser tank AC3; also used as a ground station. Commonly known as the WS19 or '19 Set'. One of the first "cross-band" radios, it was manufactured in large numbers in the UK, Canada, USA and Australia and was widely used. It contains a tuneable 2 to 8 megahertz (MHz) HF transmitter / receiver (the A set) operating on either radio telephone (R/T), CW or MCW (tone-modulated CW) with a range of 10 miles on R/T or 20 miles on CW between vehicles; some versions also had a 230-240 MHz VHF R/T transmitter/receiver (the B set) with a range of several hundred yards, and an intercom amplifier for AFV crew's headsets (the C set). Some control boxes include a 'rebroadcast' feature that allowed HF receptions to be transmitted on VHF, and vice-versa.
