On the Hesselberg , near Wassertrüdingen , operates the German radio tower , a subsidiary of Deutsche Telekom AG , the transmission tower Hesselberg (also known as radio transmission station Wittelshofen 1 ) is dedicating FM , digital TV , mobile and radio .
The 121 m high transmitter, visible from afar, is a basic network transmitter for the Bavarian DVB-T transmitter network. The transmission area includes the region of western Central Franconia and northern Swabia .
The 674 meters above sea level. The transmission tower located above sea level is of an unusual design: It is designed as a hybrid tower and consists of a free-standing steel lattice tower as the substructure and a guyed transmission mast as the upper part. At a height of 35 meters, 40 meters and 88.50 meters, the mast has radio relay platforms.
The present transmitter building was built from 1968 to 1970. In 1970 the analogue television stations were put into operation. In 1993 the transmitter received a new, five-tonne GRP cylinder that contained new TV transmission antennas. The total cost of the renovation amounted to DM 2.1 million .
Until the switch to DVB-T on November 25, 2008, analog television was broadcast.
Radio amateurs also maintain a relay station for radio , packet radio and ATV on the Hesselberg . The energy for the operation is generated exclusively by solar cells and wind power. The respective transmitters on the frequencies 439 MHz, 1240 MHz, 2400 MHz and 10.2 GHz are operated with the 15 W ERP (24 W EIRP ) approved by the Federal Network Agency . This can lead to disruptions in model flight operations in the 2.4 GHz band on the Hesselberg, which is why the 2.4 GHz relay on the Hesselberg is controversial.
Since January 14, 2014, a second station operated by radio amateurs has been operating in APRS mode with the call sign DB0EBZ in the Hesselberghaus of the Evangelical Education Center in Hesselberg, and on August 6, 2016, a DMR relay was activated under the call sign DB0HLB .

Digital television ( DVB-T )
DVB-T will end on April 24, 2018 at the Hesselberg station. For cost reasons and due to the overall improvement in the coverage provided by the DVB-T2 standard, a DVB-T2 HD conversion has not been implemented at the Hesselberg site. The coverage of the region should then be guaranteed by the transmitters Dillberg , Nuremberg , Büttelberg and Aalen .
