The Holzkirchen transmitter was a radio transmission system operated by the International Broadcasting Bureau (including the operator of Radio Free Europe ), which was built in 1950 on a former military airfield near Holzkirchen and went into operation on May 1, 1951. The transmitter served to broadcast news programs in the languages ​​of Eastern European countries and broadcast in the medium and short wave range , with the medium wave transmitter mainly transmitting the Czech program. In order to make the reception of the broadcasts from Radio Free Europe more difficult, numerous jammers were used in the Eastern European countries . In order to still enable reception, broadcasts were often carried out alongside the intended frequencies, which also led to interference with neighboring stations.

Impact on the environment

The IBB transmitters had powers of up to 250 kW and worked with strong directional radiation (the 150 kW medium wave transmitter had a high antenna gain in the main beam direction ). Some residents claimed that the emissions from the system would make them sick, but these statements have not been scientifically confirmed. In the case of numerous scientifically observed, similar and sometimes significantly more powerful transmitter systems, no such effects could be proven statistically relevant by the ICNIRP .

history

When the IBB was allowed to broadcast from the Czech Republic after the fall of the Wall , the medium-wave transmitter was used for Polish-language broadcasts. After the medium-wave transmitter of the WDR in Langenberg was switched off on the frequency 1593 kHz, the medium-wave transmitter switched to this frequency, on which it was in operation until 2001 for broadcasts in Serbo-Croatian .

The shortwave transmitter was also dispensable in the course of political developments and broadcasting in Holzkirchen was finally stopped on December 31, 2003. In April 2004 the last shortwave transmitter was removed and in August 2004 the entire area was cleared and the antenna systems demolished.

A golf course, which opened in summer 2007, was built on the former transmitter site.
