DF radio network North Sea
To support navigation and to improve the emergency service in the North Sea , a radio beacon network was set up in the 1940s by order of the British occupying powers . This made it possible to determine the location of every single ship that had a current telegraph transmitter on board.
A direction finder station was initially set up in 1946 on the island of Neuwerk , further direction finder stations were located in Sankt Peter-Ording and on the island of Norderney . Elbe-Weser Radio was the direction finding radio station. In 1949 the direction finding station was moved from Neuwerk to the Holter Höhe near Cuxhaven and thus to Elbe-Weser Radio due to the difficult supply of the crew on the island (especially in winter and bad weather) . This DF radio network was used very often, but had the disadvantage that it was initially limited to medium wave only. Call sign of the direction finding network in telegraph radio ( working channel 410 kHz ) was DAQ, later in radio communications the name of the coast radio station was used with a trailing "Gonio", ie bsplsw. "Sankt Peter-Ording Gonio".
In 1949 two emergencies occurred in which it was not possible to locate the position of the damaged ships with sufficient accuracy with the available technology. Therefore, a new system in the threshold wave range was built in 1951 in the village of Pferddemoor near Altenwalde.
Already in 1950 the bearing requirements of the ships were lower, as they now had their own, more modern navigation systems. The network was shut down on December 31, 1994.
