The story
The name Transradio dates back to 1918 when Transradio was founded as a subsidiary of Telefunken. In 1919, TRANSRADIO-Aktiengesellschaft für drahtlosen Überseeverkehr was the first company to introduce duplex radio transmission worldwide.
Telefunken Sendertechnik GmbH, which had existed since 1989 was renamed Telefunken SenderSysteme Berlin AG in 2000. Five years later the company became TRANSRADIO SenderSysteme Berlin AG. The nominal capital of 1.5 Mio € in 2010 was increased to 1.87 Mio €. After massive losses since 2007 and in spite of further loans to the tune 1.8 Mio € from its majority shareholder Bevita Commercial Corp.(Vaduz), TRANSRADIO filed for insolvency on 1st August 2017.
