Experimental Radio Station Eberswalde

The experimental radio station Eberswalde was a pioneer institution in the field of technical transmitters. It was built in Eberswalde, headquartered in Berlin in 1908 at the Finowkanal of the Held & Francke Bauaktiengesellschaft and opened on 13 February 1909 by the Telegraphenbauanstalt C. Lorenz AG, Berlin- Tempelhof as "Radio Lorenz, Eberswalde ".

History

The radio station used as an umbrella antenna system antenna, which was worn on a 70 meter high guyed mast Central and at the edges of sixteen 30 -meter-high wooden poles. The central mast was a guyed lattice tower in five levels of wood with a weight of 10.2 tons.

As transmitters arc and machine stations were used, which were used mainly for the purpose of Telegrafieübertragung. From 1920 regular experimental broadcasts are transmitted with language programs, from January 1923 to January 1925 also music programs have been transferred, although the station was never a radio station.

From 1924 the station for short wave experiments served. 1928 was built at the experimental radio station Eberswalde 's first experimental radio beacon. It worked in the medium-wave band and used a triangular patch antenna, which was suspended on three 28 meter high masts. From the mid- 1930s, the experimental radio station Eberswalde was gradually decommissioned. In 1939, the entire antenna systems has been dismantled, including the central mast. From 1942 the premises for a research position for Torfverwertung were used. It was hoped to be able to make of peat fuel. From 1954 to 1963, the buildings that are now unused, the forestry faculty of the Humboldt University in Berlin served.
