Edgar F. Johnson started his mail-order parts business in 1923, in his Wisconsin bedroom. He moved into manufacturing parts, then into making whole radios. He gained a reputation for making sturdy, reliable gear which could take commercial 2-way use.

Today’s E.F. Johnson is a leading maker of Project 25- compliant digital radios for public safety and military applications. It was purchased in 1997 by software manufacturer Transcrypt International. In 2005, its headquarters moved to Irving, Texas
