The Sottens Transmitter is the nationwide transmitter for French-speaking Switzerland. The transmitter is located at Sottens, Canton of Vaud, Switzerland. It is run on 765 kHz with a power of 600 kilowatts and is easily receivable during the night throughout the whole of Europe. Since 1989 the aerial used has been an aerial with feeding in the middle, fixed on a 188-metre high grounded freestanding steel framework tower. Before 1989 a 190-metre high self-radiating, free standing steel framework tower was used as a transmission aerial. The Sottens transmitter most recently broadcast Option Musique radio programme from Radio Suisse Romande, up until 5 December 2010.
Further there is a 125 metre tall free-standing lattice tower on the site. This tower, which was built in 1931, carried until 1958 together with a second tower of same height, which was dismantled in this year and rebuilt in Dole as TV transmission tower, a T-antenna for mediumwave broadcasting. In 1958 this tower, which is insulated from ground, was rebuilt in a tower radiator and used as backup antenna.
After the shutdown of RSR on MW, the antenna was later used for ham radio experiments in February 2011, using both standard AM and DRM in the 80 m band.
