The transmitter Weißkirchen wsa a medium wave broadcasting facility located near Weißkirchen, Oberursel, Germany. It was the most powerful European AM transmitter of the American Forces Network and transmitted on 873 kHz with a power of 150 kilowatts. It started operation in May 1951 on 872 kHz and moved its frequency to 873 kHz in 1978 according the regulations of Waveplan of Geneva. At this time, its aerial is still there, consisting of three guyed lattice steel masts built in 1954/55. These masts, which are each 86 metres tall and insulated against ground are arranged in a row with a distance of 140 metres between each mast. At daytime omnidirectional radiation is used, whereby usually the mast in the middle of the row is used. At nighttime directional radiation by usage of all three masts is applied.
As the numbers of American forces stationed in Europe has waxed and waned over the years, in response to developments in politics such as the end of the Cold War, this transmitter has remained operational, though its observed signal strength appeared far less able to compete with other Medium-Wave broadcasters compared to reception reports made in the early to mid-1970s. For many European listeners in the 1970s and 80s, its relays of United States domestic networks provided the only American radio receivable in Germany, excluding stations specifically intended for overseas reception, such as the Voice of America.
The transmitter ceased broadcasting on Friday May 31st, 2013 (http://www.afneurope.net/Headline/tabid/2098/Default.aspx?aid=28284).
