Swan Electronics
Swan Electronics was a manufacturer of amateur radio gear located in Oceanside, California, USA.
==History==
Herbert G. Johnson, W6QKI founded Swan Engineering. Johnson built the first ten largely vacuum tube type design single sideband (SSB) transceivers in a garage in Benson, Arizona in 1960-1961. The more expensive Collins KWM-2 was the only other competing transceiver at the time. The operation moved to Oceanside California where, at one point, more than 400 radios per month were being manufactured, and some estimates say that more than 80,000 transceivers were sold during the company's lifetime.〔http://www.pcs.mb.ca/~standard/ Swan Virtual Museum〕
Swan merged with Cubic Corporation in 1967, and Johnson managed Swan as its subsidiary until 1973. Johnson founded Atlas Radio in 1974. Atlas produced smaller solid state radios for mobile communications from vehicles of all types.〔http://www.qsl.net/on6ab/History.html Swan History〕
Many Swan radios remain in service today, restored and operated by vintage amateur radio enthusiasts.
