The state transmitter Beromünster was a transmitter for medium-wave broadcasting in Switzerland . During its existence, the transmitter was not located in Beromünster itself, but in what was then the municipality of Gunzwil LU ( Sursee Office ).

It broadcast the public service program of the same name, Radio Beromünster .


The transmitter began operating on June 11, 1931 and was used until December 29, 2008.

The main transmission tower on the Blosenberg has been a listed building since 2009, the equipment of the former medium wave transmitter is now on display in the Museum for Communication in Bern . A redesign of the main transmission tower to the museum is in consultation.

Since 2010, the center for art and culture in the state broadcaster Beromünster (KKLB), an initiative of the artist Werner Zihlmann alias Wetz , has been located in the transmitter's former company building .


The state transmitter Beromünster began operations as the new medium wave transmission system in Switzerland on June 11, 1931 with a T antenna on two 125 m high transmission masts in Gunzwil. An increase in the transmission power and the construction of the Blosenberg tower as a self-radiating transmission mast in 1937 made the signal receivable in large parts of Europe . The two towers of the T antenna continued to carry an antenna for medium wave. In 1962 the west tower was dismantled and rebuilt as the St. Chrischona transmission tower for VHF radio and TV . The east tower that remained in Gunzwil served as the Beromünster reserve transmission tower .

The state transmitter Sarnen , which was activated in 1973, replaced the signal of the state transmitter Beromünster, which was now heavily disturbed in the dark ( ionospheric influence ) by co-channel transmitters. The Sarnen station was monitored from the company building in Beromünster.

With the implementation of the Geneva Wave Plan from 1978, the Beromünster transmitter was receivable on medium wave at the frequency 531 kHz and at the same time marked the lower end of the official medium wave range. The old frequency was 529 kHz. Between 1969 and 1992 the state broadcaster Beromünster could also be heard on a second frequency of 1566 kHz. The transmission power was last 180 kW. In 2002 it was found that the transmitter with the transmission power of 600 kW at that time exceeded the ordinance on emission limit values ​​for non-ionizing radiation (NISV) that came into force in 2000 , which would have required complex and cost-intensive renovation for this output . As medium wave broadcasting is becoming less and less important, it was decided to switch off the station at the end of 2008. On December 29, 2008 at 00:00 CET, the first program Musigwälle 531 was taken from the station. After three days with an endless announcement, the carrier signal on 531 kHz was definitely switched off on December 31, 2008 at exactly 11:59:01 pm.
