The earliest portable field radios were designed for the bush pilots of Consolidated Mining and Smelting who had to fly their planes between remote sites in the far north of Canada. The first true walkie-talkie was built by Hings in 1937, but was ignored until the war broke out. CM&S loaned Hings to the Department of National Defence and the National Research Council in Ottawa to help redevelop his invention for use in battle. They were also called wireless sets, or “pack sets”. The term “walkie-talkie” (sometimes “talkie-walkie”) was coined by journalists reporting on these new inventions during the war.
