About the station

This channel was 765 kHz on the medium wave frequency with last 170 kW: operating performance and could be heard during the night hours in many parts of Europe ( 600 to 2009 kW). The station began operation in 1931 on the frequency 677 kHz ( 443.1 meters) with a power of 25 kilowatts. Reinforcements of the transmission power found in each case 1934 (100 kW), 1950 (200 kW), 1970 (500 kW), 1988 (600 kW) instead of what new stations were installed in the respective years. From 1947 to 1989, a 190 meter high lattice tower even more radiant, which was designed as a shrinkage -reducing antenna was used as a transmitting antenna. Prior to a T antenna, which was stretched between two 125 -meter-high steel truss masts was used from 1931 to 1947. The T- antenna was dismantled in 1958, dismantled one of the two poles and rebuilt in La Dole as a television broadcast tower. The other tower, which is insulated from earth remained in Sottens, was transformed into a radiating transmitting tower and now serves as a reserve antenna. On 21 September 1989 at 16:04 local time clock of the 190 meter high transmission tower was blown up because he needed by the onset of rust higher maintenance costs. In the same year a 188 -meter-high free-standing steel framework tower was built with a cage antenna with central supply as a replacement for the busted transmission tower. By 1994, the first program of the French-speaking Switzerland Radio Suisse Romande ( Radio Télévision Suisse today ) broadcasting was aired on the station since 1994, ran through the transmitter of the program at this time newly launched Option Musique. Since the transmitter had the more stringent limits in Switzerland not adhered to non- ionizing radiation and a reorganization would have a further power reduction, and thus a range slump result, the transmitter should be turned off on December 3, 2010. In fact, however, ran until 31 December 2010 Note loop that had pointed to alternative reception options for Option Musique.

The transmission system was used according to the cut-off from 28 January to 5th March, 2011 by radio amateurs. On 13 and 20 February 2011 was also sent in DRM.
