Swan Electronics

Swan Electronics was a manufacturer of amateur radio gear located in Oceanside, California, United States.

Johnson built the first ten largely vacuum tube type design single sideband (SSB) transceivers in a garage in Benson, Arizona, in 1960-1961.

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.

One of the distinguishing design features of that generation of Swan transceivers was their dual rate, gear-driven tuning dial.

Improved models of the two transceivers were periodically introduced well into the 1970s along with accessories, including a remote VFO (for separate control of receiver and transmitter frequency) and the Mark-I and Mark-II linear amplifiers.

Swan also designed a matched, separate receiver and transmitter pair, the 600R and 600T, which together offered better performance, higher output power and many more features than the transceivers could.
