Helgoland Radio
Helgoland Radio , callsign KHG ( K üstenfunkstelle H el g oland ), was a German coastal radio station on the German island of Helgoland that was active in the 1920s. The Deutsche Reichspost opened the station on March 10, 1921, but it was shut down again in the early 1930s. Later, the Deutsche Bundespost operated a coastal radio station on Heligoland, which was finally remote-controlled by Elbe-Weser Radio . After the German coastal radio stations were shut down by Telekom on December 31, 1998, the Hamburg ship reporting service reopened a remote coastal radio station on Heligoland on April 7, 1999.
history
In 1920 planning began for a coastal radio station on Heligoland. At the end of the First World War, there was a radio system of the Imperial Navy on the island's upper land . The coastal radio station should, however, be set up in the Helgoland post office and thus on the lowlands. The range of the future station was already structurally impaired. The navy agreed to give the Reichspost some equipment for the new station. Construction began in February 1921 and commissioning took place on March 10, 1921.
technology
Two receivers from Telefunken ("MUZE", Marine Universal Cell Receiver) were available for the frequency range 30 to 750 kHz. On the transmitting side, a G800 Lorenz sound spark transmitter was used for telegraphy in the frequency range 330 to 1000 kHz. An EV 192 tube amplifier from Telefunken was also available.
