A walkie-talkie, more formally known as a handheld transceiver, HT, or handheld radio, is a hand-held, portable, two-way radio transceiver. Its development during the Second World War has been variously credited to Donald Hings , radio engineer Alfred J. Gross , Henryk Magnuski and engineering teams at Motorola .
Donald Lewes Hings, CM MBE (November 6, 1907 – February 25, 2004) was a British-Canadian inventor, born in Leicester, England.In 1937 [1] he created a portable radio signaling system for his employer CM&S, which he called a "packset", but which later became known as the "Walkie-Talkie".
Henryk Władysław Magnuski (January 30, 1909 – May 4, 1978) was a Polish telecommunications engineer who worked for Motorola in Chicago.He was a primary contributor in the development of one of the first Walkie-Talkie radios, the Motorola SCR-300, and influenced the company's success in the field of radio communication.
After the war the FCC allocated the first frequencies for personal radio services; the Citizens' Radio Service Frequency Band (1946). Gross formed Gross Electronics Co. [ 5 ] to produce two-way communications system to utilize these frequencies, and his company was the first to receive FCC approval in 1948. [ 2 ]
Although a relatively large backpack-carried radio rather than a handheld model, the SCR-300 was described in War Department Technical Manual TM-11-242 as "primarily intended as a walkie-talkie for foot combat troops", and so the term "walkie-talkie" first came into use. [3] The final acceptance tests took place at Fort Knox, Kentucky in Spring ...
The SCR-536 is often considered the first of modern hand-held, self-contained, "handie talkie" transceivers (two-way radios). It was developed in 1940 by a team led by Don Mitchell, chief engineer for Galvin Manufacturing (now Motorola Solutions) and was the first true hand-held unit to see widespread use. [1]
Motorola was founded in Chicago, Illinois, as Galvin Manufacturing Corporation (at 847 West Harrison Street) [9] in 1928.. Paul Galvin wanted a brand name for Galvin Manufacturing Corporation's new car radio, and created the name "Motorola" by linking "motor" (from motor car) with "ola" (from Victrola), which was also a popular ending for many companies at the time, e.g. Moviola, Crayola. [10]
The first two-way radio was an AM-only device introduced by the Galvin Manufacturing Corporation in 1940 for use by the police and military during World War II, and followed by the company's 1943 introduction of the Walkie-Talkie, [3] the best-known example of a two-way radio. [4]
