Hallicrafters
The Hallicrafters Company manufactured, marketed, and sold radio equipment beginning in 1932. The company was based in Chicago, Illinois, USA.
History
William J. Halligan founded his own radio manufacturing company in Chicago in late 1932. Prior to this, he had been involved in radio parts sales for some years but decided that the time was right for a handcrafted amateur radio receiver - the company name being a combination of Halli(gan) and (hand)crafters.
The new company was located at 417 State Street and immediately ran into patent difficulties when RCA decided to sue them for building radio sets without an RCA patent license. An opportunity came to purchase the concern of Silver-Marshall Inc. in 1933 and, with it, an RCA patent license as the most valuable asset.
In order to meet their financial obligations, Hallicrafters produced radios for other manufacturers until they were financially able to begin production of their own line of communications receivers, starting with the SX-9 'Super Skyrider', in late 1935.
