history
The Bielstein has been a radio station location since 1951 . Until 1954, the Teutoburg Forest transmitter had a 60 m high transmission mast, over which an FM program with a transmission power of 3 kW was broadcast. This mast was replaced in 1954 by a 102 m high construction.
After a two-year construction period, a 298 m high tubular steel mast was put into operation in 1970 to close the remaining supply gaps. After a Pardune was torn off on January 15, 1985 at 6:26 am due to icing and squalls , it fell over. It was then replaced in 1986 by a 302 m high, guyed steel truss mast.
On April 6th and 7th, 2006, the transmitter was converted to DVB-T by replacing the top of the mast . This reduced the height to 290 m. The broadcast of the DVB-T signal began on May 29, 2006.
