The Aholming transmitter was a 500 kW long wave transmitter from Media Broadcast GmbH for the frequency 207 kHz near Aholming in Lower Bavaria . It broadcast the Deutschlandfunk program from the beginning of 1989 to the end of 2014 and during this time was one of the two longwave transmitters of Deutschlandfunk, along with Donebach . The two radio masts were blown up on March 29, 2018.
technology
Two grounded guyed steel truss masts 265 meters high with a square cross-section formed a directional antenna. The three bracing by backstays were amounting to 101, 203 and 239 meters. The transmission energy was fed in via the 2nd Pardune at a height of 203 meters. The two masts stood on an axis of 140 degrees at a distance of 483 meters. The technical equipment was largely the same as that of the Donebach transmitter; due to the higher transmission frequency, the masts were lower and their distance less.
The geographic coordinates of the masts were:
- Northwest mast: 48 ° 43 ′ 50.5 ″ N , 12 ° 55 ′ 46.6 ″ E
- southeast mast: 48 ° 43 ′ 38.4 ″ N , 12 ° 56 ′ 1.6 ″ E
history
The Aholming transmitter went into operation on January 1, 1989 and replaced the transmitter in Erching , which had to be switched off at night due to the lack of possibility of using directional radiation (only one mast available) due to the requirements of the Geneva Wave Plan .
In 2008 the old tube transmitter was replaced by a fully transistorized system from Transradio Sendersysteme Berlin . Since February 15, 2008 the transmission system has belonged to Media Broadcast .
The shutdown of the analogue broadcast of Deutschlandradio programs via long wave at the end of December 31, 2014 was carried out in accordance with the specifications of the Commission for Determining the Financial Requirements of Broadcasters (KEF). Due to the decreasing use of this technology and the simultaneous progressive digitization of radio, this had pushed for the shutdown of cost-intensive long-wave broadcasting. The savings are now to flow into the further expansion of the DAB + transmitter network.
