The transmitter Erching was a longwave transmitter, built 1952-1953 in the vicinity of the Hallbergmooser hamlet Erching. He used as a transmitting antenna a 256 meters high, insulated against ground guyed lattice steel mast with top capacity and he was at the time of its commissioning in 1953 with a transmission power of 1000 kW, the strongest radio stations in the world.
The program of the Voice of America has been radiated from the transmitter Erching his time mainly for the Eastern European countries. However, the program of the RIAS has also at times disseminated. It was broadcast on the frequency 173 kHz. To complicate the reception of the transmitter Erching program, some radio stations were taken ( no jamming ) in operation at the time on this frequency, even in Russia, which send some still do.
A peculiar feature of the power station; they was using its own generators, since all transmitters were designed as American appliances for a supply of Dreh-/Wechselstrom 60 Hertz and a converter or inverter American operators was apparently too expensive. For this reason, the station building had large characteristic oil tanks, which gave the whole complex of the face of an oil refinery. Only when the German Federal Post Office took over the station, a transformer has been installed and switched the power supply to the power supply from the public grid.
Until recently, transmitters were used in which the modulation performed according to the method Doherty. These devices were efficient, but required if applicable high coordination. When in 1988 the frequency had to be reduced to 2 kHz ( 209 kHz to 207 kHz of ) the sender was two days out of service.
1973 Erching transmitter was shut down as part of the policy of detente, but in 1979 reactivated even for tests of the radio navigation system LORAN -D. In the framework of the Geneva wave plan allowed the former German Federal Post Office, for this transmitter, the longwave frequency 209 kHz (from 1988: 207 kHz) to obtain and utilize the transmitter Erching for broadcasts of the Germany radio program. There had to be applied at night for the use of this frequency by requirements of the Geneva Plan directional wave radiation and no second antenna support could be established because of the nearby under construction new airport Munich, that station had to be shut at night.
For this reason, they sought a new location for the transmitter and found him in 1985 near Aholming. With the commissioning of the transmitter, the transmitter Aholming Erching was shut down and dismantled.
Today is the site privately owned and is marketed for film and photo shoots.
