The longwave transmitter Erching was a longwave broadcasting facility of the Voice of America established in 1953 near Erching, Bavaria, Germany. This transmitter, which used a 256 metre high guyed-steel-framework mast aerial, was at the time of its inaugauration the most powerful radio station in the world with a transmitting power of 1000 kilowatts

In 1973, this facility was shutdown because of a relaxed political climate. In 1979, it was used for LORAN-D tests. The German Federal Post succeeded, by a workout of the waveplan of Geneva, in getting a new frequency for this transmitter and using it for broadcasting the program of Deutschlandfunk. Because directional radiation was required at night time for which a second aerial mast had to be erected, impossible because of the planned (and 1992 opened) new Munich International Airport, the transmitter had to be shutdown at night time.

A new transmitter site was consequently placed at Aholming in 1985. After the completation of the longwave transmitter Aholming, the longwave transmitter Erching was shutdown and dismantled. Presently, they are dependent on the German Federal Intelligence Agency.
