One of the pioneers of mobile voice radio and of the military walkie-talkie was Canadian engineer Donald Hings (1907-2004). In1938 he designed a portable emergency voice radio for use by airplane pilots and others in remote, mountainous areas. During the Second World War Hings worked for the National Research Council, where he was responsible for designing what became the highly successful Wireless Set (Cdn) No. 58, or C-58 set, as well as a number of other pieces of radio equipment. During the course of his career Hings was awarded more than 50 Canadian and U.S. patents. In recognition of his service to the war effort and outstanding contributions to technology, Hings was recognized as a Member of the British Empire (MBE) and a Companion of the Order of Canada (C M)

Function

TO TRANSMIT, RECEIVE AND AMPLIFY RADIO FREQUENCY AND AUDIO FREQUENCY SIGNALS FOR RADIO-TELEPHONE COMMUNICATION.

Technical

Appears to be a Wireless Set (Cdn) No. 58 Mk.1. The C-58 set was one of the first military "walkie-talkies," developed in Canada for short-range voice communication by infanrtry patrols and paratroops and for inter-batallion communication. Using amplitude modulation, it operated at 6-9 MHz and, depending on the antenna used, had a range of 3-8 km. This is not a handheld device -- the operator carried it over his left shoulder and operated it with his right hand. The radio was powered by a dry cell battery (carried in a separate Signals Satchel), or by a vibrator power unit (.2) connected to a vehicle battery.Thousands were made by Canadian manufacturers during the Second World War. [Ref. Louis Meulstee, Wireless for the Warrior, Vol. 1 (Broadstone, UK: G.C. Anrold, 1995).
