Transradio
From Wikipedia, the free encyclopedia
In 2005, Telefunken SenderSysteme Berlin changed its name to Transradio SenderSysteme Berlin AG. The name Transradio dates back to 1918 when Transradio was founded as a subsidiary of Telefunken. A year later in 1919, Transradio made history by introducing duplex transmission. Transradio is specialised in research, development and design of AM, VHF/FM and DRM broadcasting systems.
