Teltron
Teltron GmbH

Teltron was a medium-size electronics company in München (Germany), that produced secure speech solutions for the police and other law enforcement agencies in the days of analogue two-way VHF and UHF radio, selling rebatched (OEM) as well as in-house developed equipment.


With the introduction of digital two-way radio, such as Tetranet, many law enforcement agencies in Europe abandonned analogue radio and, hence, the voice scramblers and other secure voice products that were used with such radios. As a result, Teltron GmbH lost most of its turnover and was eventually dissolved in 1988. The name 'Teltron' is used by several other companies, both in Germany and abroad, which are not related to the former Munich-based crypto manufacturer.
