From 1952 until 1992 the DECCA transmitter Zeven belonged to the German DECCA chain, which consisted of transmitters at Brilon, Stadtkyll and Coburg-Lautertal. In this chain it was the "Green" station and transmitted on 127,1100 kHz. After 1968 the station served also in the Frisian DECCA-chain as the "Purple"-station and used the frequency of 71.433 kHz. From 1992 until the shut-down of Frisian Decca chain on December 31, 1999, this station was operated exclusively for this DECCA chain.

After shut-down of DECCA, the facility was not used until the 2004. At this year it started transmitting of DGPS-signals on the frequency 303.5 kHz.

In 2017 the 93m tall mast was demolished, because a new built steel lattice tower adopted its task.
