The Eberswalde experimental radio station was a pioneering institution in the field of technical transmission systems . It was built in 1908 in Eberswalde on the Finow Canal by Held & Francke Bauaktiengesellschaft based in Berlin and opened on February 13, 1909 by C. Lorenz AG from Berlin-Tempelhof as "Radio Lorenz, Eberswalde".
history
The radio station used as an antenna system, a screen antenna , which was worn on a 70 meter high, guyed central mast and at the edges of sixteen 30-meter high wooden poles. The central mast was a wooden lattice mast guyed in five levels and weighing 10.2 tons.
- “Eberswalde is the real and real birthplace of German entertainment broadcasting. In 1919, the first wireless concerts "To all" were organized from Eberswalde, which contributed significantly to making the achievements of German radio technology known all over the world ... "
Arc transmitters based on patents of the Danish inventor Valdemar Poulsen , for which C. Lorenz had acquired the rights in 1906 , were initially used as transmission devices . Machine transmitters followed , which were mainly used for telegraphic transmission. From 1920 experimental programs with language programs were broadcast on a regular basis, from January 1923 to January 1925 music programs were also broadcast, although the station was never a radio station.
From 1924 the station was used for shortwave experiments . In 1928 the first experimental radio beacon was set up at the Eberswalde test radio station. It worked in the medium wave range and used a triangular plane antenna that was suspended from three 28-meter-high masts. From the mid-1930s, the Eberswalde test radio station was gradually shut down. In 1939 the entire antenna system including the central mast was dismantled. From 1942 the premises were used for a research center for peat utilization. It was hoped that peat could be used to make fuel. From 1954 to 1963 the buildings, which are now unused, served the forestry faculty of Berlin's Humboldt University.
