The broadcasting station Münchenbuchsee was put into operation in 1922 as the first fixed longwave transmitter in Switzerland. The plant was shut down in 1981 and partially dismantled.

prehistory

During the First World War there were significant problems with the transmission of telegrams by wire because of censorship or other disabilities. During the war, an inquiry was made for a wireless telegraph station at " Telefunken " Berlin. The planned large station for overseas connections was rejected due to the costs of CHF 3.5 million.

For the first League of Nations assembly in November 1920, the Marconi Society provided a provisional transmission system for its own account in Bel-Air near Geneva in order to prove the efficiency of wireless telegraphy .

history

On March 11, 1921, the Swiss Federal Council granted the Marconi Wireless Telegraphen Co., London, for a company yet to be founded, the license to build and operate a wireless telegraph station . The Swiss Marconi radio station was then founded with share capital of CHF 1,7500,000, with the intention of taking over operations for a period of up to 25 years. The aim was to put the transmitter into operation by the next League of Nations assembly in September 1921. Shortly afterwards, the two steel towers with a height of 91.5 meters, twenty small towers and the necessary buildings were built on a hill south of Münchenbuchsee. The first telegrams for test purposes could already be sent to London in August, so that provisional operations could begin in September during the second League of Nations assembly.

On April 26, 1922 the festive opening ceremony took place in the presence of various invited guests.

The whole Marconi station consisted of the transmitter system in Münchenbuchsee, the receiver system in Riedern and the headquarters in the main post office building in Bern. The Marconi station is only intended for continental traffic, telegrams for dispatch to American, African, Asian countries and Australia are forwarded via London. Although Moscow is 500km further than the promised 2000km, an attempt to send telegrams directly was successfully completed. Thus telegrams could now also be sent directly to Moscow.

In 1924, the Swiss Confederation bought back shares from the English Marconi Wireless Telegraphen Co. and issued additional shares to expand the facility, making it the majority shareholder.

Radio Cooperative Bern

In 1925, an additional 40m mast was built for the Bern radio cooperative and a transmitter with a capacity of 1.2 kW was installed. On November 19, 1925, the spokeswoman Betty Spengler reported on the ether for the first time: "Hello, here Radio Bern on wave 302". The program from the studio in the Kursaal is broadcast via the Münchenbuchsee broadcasting station.

In 1928 the Marconi radio station was renamed “ Radio-Schweiz Aktiengesellschaft für wireless Telegraphie und Telephonie, Bern” in order to emphasize its national importance.

From 1930 onwards, the Bern radio cooperative broadcast from a new transmitter near Wankdorf in Bern.

In 1933 it consists of the following elements:

  • Two long wave transmitters Marconi with approx. 14kW anode power. They send antennas that are stretched between two 90m and one 125m mast, the required electrical power is transformed in a separate transformer house.
  • A shortwave telegraphy transmitter type Marconi with an output of 4kW
  • A short wave transmitter with max. 20kW of power for traffic with America. The four transmitters are connected by land lines with the main telegraph office of Radio Switzerland in Bern.

From probably 1941 Radio Schweiz AG operated the only coastal radio station from an inland area with the callsign HEB under the name Bern Radio .

The dismantling

In 1977 the coastal radio transmitter HEB was relocated to Prangin VD.

In 1982 the three radio masts of Radio Schweiz AG in Münchenbuchsee were demolished.

In 1983 the building rights were transferred to the community of Münchenbuchsee. They are now used as a hall and leisure facility.

Specialty

Today the HB9F Bern relay community is rented in part of the former transmission system and maintains various relay stations and beacons .
