National broadcaster in Switzerland

from Wikipedia, the free encyclopedia

Various broadcasting systems in Switzerland were designated as national broadcasters . They started operations in the 1930s.

Locations

In accordance with the three official national languages ​​of the time, medium-wave broadcasting was divided between the three transmission systems of the regional broadcasters Beromünster (German-speaking Switzerland), Monte Ceneri (Italian-speaking Switzerland) and Sottens (French-speaking Switzerland).

Infrastructure

The facilities in Beromünster and Sottens were opened in 1931 and each operated with a T antenna , which was supported by two 125 m high steel lattice towers . The Monte Ceneri facility was opened in 1933 and operated as a self-radiating transmission mast with a 190 m high steel lattice tower.

To increase the transmission power , a 190 m high steel lattice tower was also built in Sottens and in 1937 the Blosenberg tower in Beromünster was built as a self-radiating transmitter mast and made the signals receivable in large parts of Europe . The towers of the T antennas continued to carry antennas for medium wave. Later the T antennas were dismantled and one tower per transmitter was dismantled, so in 1958 one of Sottens was used as the La Dôle transmitter and in 1962 the west tower of Beromünster was used as the St. Chrischona television tower . The towers that remained at their home locations were isolated from the earth and converted into self-radiating transmission towers. They were used as Sottens reserve transmission tower and Beromünster reserve transmission tower .

The infrastructure included the medium-wave filling transmitter in Savièse from 1943 to 2005, the HBG time signal transmitter in Prangins from 1966 to 2011 and the Sarnen state transmitter from 1973 to 1992 , which, unlike the other state transmitters, broadcast in the upper medium wave range. During the night, it replaced the signal from the state broadcaster Beromünster, which was now heavily disturbed from midnight. The Schwarzenburg short-wave transmitter was used by Schweizer Radio International from 1939 .

The transmitting station Prangins and the receiving station Riedern (City of Bern ) belonged to the coastal radio station Bernradio , a shortwave station for ocean shipping.
