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.
