The two German rivals in the development of wireless communications equipment,
AEG (Allgemeine Electicitätsgesellschaft) and Siemens Halske, in 1903 joined together to
form the "Gesellschaft für drahtlose Telegraphie mbH" (Society for wireless telegraphy),
the later "Telefunken". They became strong concurrents to the Marconi Wireless Corp.
Telefunken got a good reputation with equipping the Wireless Stations of Norddeich Radio
in 1905 and Nauen in 1906. Telefunken was in fact not a manufacturer of radio
sets, but was a brand selling sets from different manufacturers (Siemens, AEG).
In 1928, Telefunken presented television equipment with mechanical scanning,
in 1938 the first electronic television studio. Commercial surveillance receivers,
military wireless stations and equipment for maritime and aeronautical communications
by Telefunken were very successful, after WWII, most of the production plants have been
dismanteled.
In 1945, Telefunken started production of domestic sets again, after few years,
it's spectrum expanded to commercial receivers and transmitters, television
and audio recording technology - soon, Telefunken got an excellent reputation in
military and commercial telecommunications.
After 1979, the company was renamed AEG - Telefunken Aktiengesellschaft, later it
has been split up and nearly went bankrupcy. After having been taken over by
French Thomson-CSF, the company joined together with DASA (Deutsche Aerospace) and
Daimler Benz and is known as Telefunken RACOM in the segment of commercial
communications technology.
Here, I focus on some most popular shortwave receivers from Telefunken,
You find a lot of information about other military and Wehrmacht Telefunken
equipment on various websites.
