Einheitsempfänger
In August 1939,
International radio exhibition Berlin
.
History
The project started in 1938, associating the
Loewe, Lorenz, TeKaDe and Telefunken. The objective was to produce 10,000 units, but the start of World War II caused only about 50 devices to be installed in military hospitals and various government departments. The Berlin
transmitter was destroyed by Allied bombing in November 1943.
Like British televisions of the era, the Einheitsempfänger could receive only one channel with its frequency pre-tuned at the factory to reduce construction costs.
