The Königs Wusterhausen transmitter on the Funkerberg in the north of Königs Wusterhausen in Brandenburg was one of the first transmitters in Germany. Broadcasting began in 1915 and continued until summer 1995. The technical equipment that is still available can be viewed alongside other exhibits in a museum that has been established there since the 1990s.
From the beginning of 1920, the Reichspost first attempted to transmit speech and music from Königs Wusterhausen (wireless telephony on the wavelength of 1300 m, and radio on the wavelengths 2525, 2900 and 4000 m.) The first radio broadcasts were the Christmas concert on the 22nd December 1920 and the Easter concert on March 23, 1921. Regular broadcasts began with the Sunday concerts, which took place on the initiative of the postal officials who played pieces of music on their private instruments.
The transmission of the telephony and radio broadcasts at the beginning of 1920 was still carried out by means of the Reichspost from the then C. Lorenz AG, provided by the arc transmission technology, because initially the Post did not have its own sound transmitter. Since the Lorenz company already had such a Poulsen arc transmitter for the transmission of speech and music in its test radio station in Eberswalde, Lorenz engineers (including Felix Gerth and Leo Pungs), who were responsible for the technology, were able to pass on their experience from Eberswalde. After private reception was officially forbidden in Germany until 1923, on October 29, 1923 the waves for broadcasting opened for entertainment and instruction, or as it was later called: entertainment broadcasting.
