History[edit]

The company began as a mail order business, selling radio transmitting parts to amateurs and early radio broadcasters and was active in World War II defense production. After the war, the company introduced its Viking line of amateur transmitters, among them, the Viking, Valiant, Ranger and Pacemaker. The company transitioned to development and manufacturing of land-mobile radio products such as CB, business radio and associated technology such as the Logic Trunked Radio trunking format. EFJohnson's discontinued Viking line of amateur radio transmitter products are collected, restored, and operated by a number of vintage amateur radio enthusiasts.[1][2]

In 1995, the Project 25 standard for interoperability was endorsed by APCO, American Association of Railroads, the National Association of State Telecom Directors, the Department of Defense, National Security Agency, National Telecommunications & Information Administration, and Department of Justice. EF Johnson signed a Memorandum of Understanding to develop products that comply with the agreement. The company was purchased in 1997 by software manufacturer Transcrypt International. Headquarters relocated to Irving, Texas in 2005 and the company became EFJohnson Technologies in 2008. In 2010, EF Johnson Technologies, Inc. was acquired by Francisco Partners.
