Pierre-sur-Haute military radio station
The Pierre-sur-Haute military radio station is a site used for French military communications. It is in the Sauvain and Job communes, with the boundary between the Rhône-Alpes and Auvergne regions passing through the site. A civilian radio relay has also been built at this location by the telecommunications company フランス語:Télédiffusion de France.
== History ==
In 1913, a semaphore telegraph (French: ''フランス語:Chappe telegraph'') was built where the military radio station is now. At the time, it was a small stone building, with the semaphore on top.〔
In 1961, during the Cold War, NATO asked the French Army to build the station as part of the 82-node transmission network in Europe known as the ACE High system.〔Jane's Military Communications (1987), cited by 〕 In this network, the Pierre-sur-Haute station, or FLYZ, was a relay between the Lachens (FNIZ) station to the south and the Mont-Août (FADZ) station to the north.〔(【引用サイトリンク】date=30 June 2012 ) And 〕 The NATO radio station was using American-made tropospheric scatter equipment to relay voice and telegraph signals on a network stretching from Turkey to the Arctic Polar Circle in Norway.〔 The French Air Force took control of the station in 1974.〔 In the late 1980s, the system was gradually replaced by a combination of national defense systems and some NATO-owned subsystems.〔 The large parabolic antennas, known locally as ''Mickey's ears'', were replaced with the current two-antenna setup in 1991.〔
