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.
Initially, Teletron developed its own products, which were mainly built
with discrete components. Later, when custom ICs became available and more
advanced methods of voice protection were required, they started selling
rebatched (OEM) devices,
such as the SP-810,
that were made by Telsy in Italy,
who were at that time developing their own custom ICs.
In the early 1980s, when Teltron was selling Telsy's
(renamed as TVC-9000), they decided to copy the designs from
and build the devices themselves again. In the mid-1980s,
a large batch of TVC-9000
units was sold to an African country.
This theft of Intellectual Property (IP) severely damaged the relationship
between Teltron and Telsy and prompted the latter to take
the necessary precaution to protect their company secrets in the future .
In the following years, Teltron introduced a range of secure voice products,
some of which were based on the
but also the very successful single-piece
that could be added to any existing VHF/UHF radio.
Some of Teltron's products were sold as rebatched produces (OEM)
by ANT in Backnang.
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.
