Copenhagen wave plan
The Copenhagen Wave Plan refers to the wave plan drawn up in Copenhagen in 1948 for the distribution of transmission frequencies for broadcasters in the long and medium wave range .
ratification
The Copenhagen Wave Plan was not signed by some of the participating countries ( Austria , Luxembourg , Sweden , Turkey , Syria , Egypt and Iceland ) because the frequency allocation was often viewed as unfair . Germany , to which very few frequencies were allocated in this plan (e.g. only two medium-wave frequencies), was not represented as the loser of the war.
Effects
Despite the criticism, the Copenhagen Wave Plan came into force on March 15, 1950. The upper limit of the medium wave range has been increased from 1465 kHz to 1602 kHz. As a result of the poor frequency assignments, the rapid expansion of the VHF transmitter networks was pushed ahead in Germany . However, in the course of bilateral agreements and in cooperation with the allied armed forces, whose transmitters such as AFN or BFBS were not included in the Copenhagen Wave Plan , it was possible to coordinate further transmission frequencies in the long and medium wave range, for example in 1953 for the German long wave transmitter .
implementation
From the beginning, the treaty was not consistently adhered to, even by the signatory countries. In the course of the 1960s and 1970s, fewer and fewer states adhered to the Copenhagen Wave Plan, so that in 1974/1975 a new wave plan for the long and medium wave range, the Geneva Wave Plan , was drawn up.
