In 1949, the first of the company's amateur radio transmitters were manufactured, the Viking I model. The Viking line of amateur transmitters included the Valiant, Ranger and Pacemaker. In 1958, the company manufactured equipment for the Class D Citizens Band Radio. One such transceiver, the Johnson Messenger, is exhibited in the Smithsonian Institution as an example of early American-made technology. More information...
