German long wave transmitter
The German long-wave transmitter was a nationwide radio program of the ARD , which was broadcast from 1953 to 1961 and was the predecessor of the later Deutschlandfunk .
history
At the beginning of the 1950s, the members of the ARD commissioned Nordwestdeutscher Rundfunk (NWDR) to produce and broadcast a nationwide radio program on long wave after the GDR radio had put a long wave transmitter ( Germany's transmitter ) into operation. After approval by the Allied High Commission , the NWDR broadcast the first test programs from January 8, 1953. For this purpose the 100 kW medium wave transmitter of the "Reichssender Hamburg" from 1934, converted for the long wave frequency 151 kHz, was used.
Only music was played which was interrupted by a measuring tone for three minutes every hour. Since radio programs with a high proportion of music were rare at the time, the then nameless long-wave program was often set in restaurants to entertain guests.
Three years later, on May 2, 1956, the North German Broadcasting Corporation (NDR) , which had now been founded, was able to start regular operation of the program. Except for news at the top of the hour, there were no innovations, otherwise only music was played. On May 1, 1958, the program was named German long wave transmitter . From now on, verbatim broadcasts and program information for all ARD radio programs were broadcast from 4 p.m. to 8 p.m., followed by a moderated music program until midnight. The respective director of the NDR was responsible for the program of the German long wave transmitter.
In 1960, the independent Federal Agency for Public Law Deutschlandfunk (DLF) with its seat in Cologne was founded by federal law . At the end of 1961, the ARD's mandate to NDR to operate the German long-wave transmitter expired. The long-wave frequency was handed over to the new transmitter Deutschlandfunk, which started broadcasting its radio program on January 1, 1962.
Broadcasting
Since no long-wave frequencies were provided for in the Copenhagen wave plan for Germany, it was decided to transmit on 151 kHz at the lower end of the long-wave band. Norway, which operated a transmitter in Tromsø on 155 kHz , gave its consent on the condition that a transmission power of 20 kW is not exceeded. The program was broadcast on the NDR's Billwerder-Moorfleet station in Hamburg. The method of AM-compatible single sideband modulation was used because the sideband that protruded into the frequency range used by maritime radio services at that time had to be suppressed.
Although the German long-wave transmitter was designed as a nationwide program, it could only be received in the northern half of Germany due to the comparatively low transmission power of 20 kW and due to the decentralized transmitter location. However, the output could be increased to 50 kW by 1962.
After the program was discontinued, Deutschlandfunk was broadcast on the Billwerder-Moorfleet station until November 30, 1962. On December 1, 1962, the Deutsche Bundespost put the 151 kHz frequency into operation for Germany radio, initially at the Mainflingen location near Frankfurt. Since 1967 the Deutschlandfunk has been broadcast on the same frequency by the Donebach transmitter in the Odenwald. At the MW conference in 1975 ("Geneva Wave Plan") Donebach was officially assigned the frequency 153 kHz.
With the discontinuation of long-wave broadcasting by Deutschlandfunk at the turn of the year 2014/2015, the Donebach station ended.
