The transmitter Vigra was a radio transmitter for medium wave of the Norwegian transmitter operator Norkring, a subsidiary of the Norwegian telecommunications company Telenor , which could also be received in Germany.
A 232-meter-high guyed tubular steel mast with a cross-shaped roof capacity was used as the transmission antenna , which was built between 1952 and 1953 as a 243-meter-high transmission mast and was shortened to 232 meters in 1999 for reasons of flight safety. However, at the end of 2007, even after this cut, the transmission mast was viewed by the responsible authorities as a threat to flight safety and its very existence was seriously threatened. The transmitter was put into operation as a long-wave transmitter in 1935 and destroyed in a bomb attack in 1940. After two provisional transmitters, a 100 kW transmitter on 629 kHz was put into operation on April 12, 1948, and it was then continued to transmit with 100 kW on 630 kHz. A T-antenna was used as a transmitting antenna until 1953.
On June 30, 2011 the transmitter, which last broadcast the regional program NRK Møre og Romsdal of the Norwegian public broadcaster NRK , was switched off and the transmission mast was blown up on September 8, 2011.
