Autophon has been founded as a specialist manufacturer for automated telephone systems in Solothurn in 1922. In 1931, the company started production of "Audio frequency Telephone Broadcast Receivers" (NF-Telephonrundspruch or NF-TR). This system used the Telephone lines for the distribution of broadcast programmes and worked on audio frequencies - in contrast to the later HF-Telephonrundspruch or HF-TR, where six radio programmes have been distributed over telephone lines using frequencies in the longwave band, not otherwise used in Switzerland. The HF-TR service remained active until 1998.
Later, Autophon produced receivers under Lorenz License and started their own broadcast receiver production in 1935. Well into the fifties, Autophon was a popular manufacturer of radios in Switzerland, but the company didn't cope with the switch to FM and television receivers.
Autophon was an active manufacturer of commercial and military communications equipment, many receivers and transceivers used in Swiss Army came from the plants near Solothurn.
The telecommunication segment of Autophone was merged into Ascom in 1987.
