European cable networks. Until the Geneva Frequency Plan of 1975 came into effect on 23 November 1978, Deutschlandfunk was transmitted on longwave from Sender Donebach and on mediumwave from Bad Dürrheim, Cremlingen, Ravensburg, Ehndorf, and Mainflingen. With implementation of the plan Bad Dürrheim was shut down. In 1979 new transmitters came into service: in Erching for daytime longwave transmission and in 1980/81 in Nordkirchen and Thurnau for mediumwave transmission. On 1 January 1989 the Aholming transmitter replaced Erching and allowed 24-hour service on the second longwave frequency. On 1 October 1994 Heusweiler transmitter, which had previously transmitted "Europawelle Saar", began transmitting Deutschlandfunk. On 31 December 1994 Mainflingen transmitter was shut down. On 31 December 2014 longwave transmissions from Donebach on 153 kHz and Aholming on 207 kHz ceased, although Donebach 153 kHz continued into the early hours of 1 January 2015 before being shut down. On 31 December 2015 all remaining medium wave transmissions ceased at 2350 CET. FM FM transmitters carry the Deutschlandfunk signal throughout Germany but there are gaps in the coverage pattern, especially — but not only — in the southern states of Bavaria and Baden-Württemberg. As the state authorities have the power to allocate frequencies to broadcasters, they give preference to the regional public and commercial broadcasters under their jurisdiction. Streaming Several streams of Deutschlandfunk are available in MP3, AAC and Opus formats. References Citations Sources Shutdown of Medium Wave Services 31 December 2015. ARD ARD: 50 Jahre Erste Reihe.
