history

Location of the Pierre-sur-Haute radio station ( ) and the other former military radio stations FADZ ( ), FROZ ( ) and FNIZ ( ) |
In 1913 an optical telegraph was built there in the Chappe system . At that time there was only a small stone building with the optical telegraph on the roof.
In 1961, during the Cold War , the French army built one of the 82 stations of the Troposcatter radio network ACE High for NATO , which, unlike shortwave radio , was supposed to work even after a nuclear war . In this network, the Pierre-sur-Haute station with the callsign FLYZ was a relay between the Lachens station (FNIZ) in the south and the Mont-Août station (FADZ) in the north. Four 10 kW transmitters (two in each direction) and sixteen receivers (eight in each direction) were used. In 1974 the French Air Force took over the management of the station. In 1988 NATO began decommissioning the ACE-High system. Today the station is still used for military communication as well as for two different civil facilities.
Current function
The Pierre-sur-Haute transmitting and receiving system is operated by the French Air Force and is subordinate to the Base aérienne 942 Lyon-Mont Verdun radar unit, 80 km away . It is one of the four radio relay stations along the French north-south axis that are in constant communication with each other. The other three are the military radio station Lacaune , the military radio station Henrichemont and the Brétigny-sur-Orge Air Base . The station is mainly used for radio communications on a cross-armed forces level. If French nuclear weapons were to be used, the order could be passed on through this station.
The station was part of the Commandement Air des Systèmes de Surveillance d'Information et de Communications (CASSIC) since its commissioning on January 1, 1994. From January 1, 2006 the station of the Direction interarmées des réseaux d'infrastructure et des systèmes d 'Information (DIRISI) subject.
Around 20 employees are on site, including electrical mechanics, mechanics and cooks. The station is headed by a major. This rank in the French army corresponds to that of a German Oberstabsfeldwebels ( NATO rank code OR-9 ).
In addition to military use, the broadcasting company TDF has a transmitter there. There is also a radar system on the civilian transmission tower , which is operated by the Direction générale de l'aviation civile and monitors and secures the airspace and flight movements at Lyon Saint-Exupéry Airport .

Trivia
In 2013, the French domestic secret service DCRI forced the chairman of the French Wikimedia association Wikimédia France Rémi Mathis to delete the French Wikipedia article on the radio station under threat of pre- trial detention . Since this chairman was also the administrator of the French-language Wikipedia, he was able to comply with the request. The article was restored after a short time and then created in additional languages.
