In 1969 Dillberg transmitter took over the
medium wave transmissions from
Nuremberg-Kleinreuth transmitter, which was shut down in this year. As the mast of Dillberg transmitter is grounded, it was equipped with a cage antenna for this purpose. The frequency of the transmitter was, until 1978, 800 kHz and then changed to 801 kHz in 1978 after the
waveplan of Geneva went in service. Although it was possible to use also the frequency 909 kHz for Dillberg transmitter, the Bavarian Broadcasting Company decided to run it on 801 kHz forming with
Transmitter Ismaning a single frequency network, as operating on 909 kHz would have required an expensive extension of the antenna as directional radiation would be required at night time for this frequency. The Mediumwave Transmitter has been officially shut down on September 30, 2015 (together with the Würzburg 729 kHz and Ismaning 801 kHz Transmitters), according to Guidelines of the "Commission for Budget Requirement of public Broadcast (KEF)" and also due to the fact that there remained only minimal auditorium for the "Bayern Plus" Program via Mediumwave, which is primarily distributed digitally today - Bavaria-wide - via DAB+ (Bavarian Bouquet), within Broadband Cable Networks and Satellite (DVB-S), as well as via Internet. ==Directional radio==
