It was ideally suited for reaching vast and remote areas that would otherwise lack FM radio reception. In a way, FM suited this band because the capture effect of FM could mitigate interference from skywaves. Transition to the Following the collapse of the communist governments, that transition was remarkably accelerated as private stations have been established. This was also prompted by the lack of equipment for the OIRT band and the modernisation of existing transmission networks. In Czechoslovakia , the decision to use the Allocated frequencies are still valid and are used in the Czech Republic and Slovakia.
The first transmitter was put into operation at The transition was finished in Hungary closed down its remaining broadcast transmitters in , and for thirty days in July of that year, several Hungarian amateur radio operators received a temporary experimental permit to perform propagation and interference experiments in the 70— The main purpose of those stations is compatibility with older equipment.
This may have been to reduce co-channel interference caused by Sporadic E propagation and other atmospheric effects, which occur more often at these frequencies. However, multipath distortion effects are less annoying than on the CCIR band. Stereo is generally achieved by sending the stereo difference signal, using a process called polar modulation. Polar modulation uses a reduced subcarrier on The 4-meter band 70— The System D television channels R4 and R5 lie wholly or partly within the Countries which still use System D therefore have to consider the re-organisation of TV broadcasting in order to make full use of this band for audio broadcasting.
Second-hand automobiles imported from Japan contain a radio designed for the Japanese FM band, and importers often fit a "converter" to down-convert the In addition to showing an incorrect frequency, there are two other disadvantages that can result in undesired performance; the converter cannot down-convert in full the regular international FM band up to Also the converter may not allow pass-through of the MW band , which is used for AM broadcasting.
A better solution is to replace the radio and antenna with ones designed for the country where the car will be used. It was even more expensive for broadcasters to rebuild their transmitters to work on the new band. Altogether, the change set FM radio back ten years. The "devastating" change was successfully lobbied for with the FCC by RCA , which did not want FM radio to become dominant, although the higher frequencies had fewer interference problems.
RCA conducted "an organized campaign of misinformation". Norway , in January , was the first country to discontinue FM as a result. From Wikipedia, the free encyclopedia. See also: FM broadcasting in Japan. This section needs expansion. You can help by adding to it.
