A total of 14 ranges are used for music and voice broadcasts on short waves. Three of them – the 60-, 90-, and 120-meter bands are for the radio stations, situated around the tropics. Thus medium waves are replaced, since they are disturbed by strong atmospheric interferences in those regions. Their broadcast was adopted at international conferences and by the International Telecommunication Union /ITU/. The 120-meter band covers the frequencies between 2300 and 2495, situated at each 5 kHz, or a total of 39 frequencies with only 7 of those used. There are more transmitters working in the next tropical band, called 90-meter and situated between 3200 and 3400 kHz. The third band – the 60-meter one is the most populated. The regulation for its usage includes the official frequencies between 4750 and 5060 kHz and the unofficially permitted ones up to 5100 kHz. The 75-meter band is situated between 60 and 90 meters. Its frequencies are provided to European and Asian radio stations. The frequencies, officially allowed for usage are 3900-4000 kHz for Asia and 3950 – 4000 kHz for Europe, while unofficially for Europe and Asia those reach up to 4050 kHz. Some radio organizations do not comply with those requirements and that is why one can find at least 30 radio stations from Indonesia, both Koreas etc. in the frequencies mentioned above. The next band – 49-meter short waves is provided for international usage from all over the globe. It covers the frequencies between 5900 and 6200 kHz, while radio shows can be broadcast unofficially on the sub-ranges between 5730 and 5900 kHz and from 6200 to 6295 kHz. The 49-meter band was called the "European one" years ago, since the Home Services of most countries had fixed frequencies within that range. However, radio fans were most intrigued over the last years by the changes in the 41-meter short wave band. For decades and for unknown reasons it was officially allowed radio shows with voices and music to be broadcast on the same frequencies. Some solutions were tried to be imposed during the World Radiocommunication Conference on July 4 2003, followed later by decisions of ITU, but with no result, despite the fact that the frequencies around that range started to look differently. Those between 6800 and 6995 can be used unofficially for radio broadcasting, as the 6800 – 6890 ones may be used exceptionally in the November – March period. Frequencies from 7000 to 7195 may be used by telegraphists mainly. The 7205 – 7350 range are for American telegraphists and for radio broadcasting from other continents. A mistake of the international radio institutions caused an argument between telegraphists and radio broadcasters over the border frequency of 7200 kHz, as both groups had been allowed to use it. Some radio stations wouldn't obey to those rules and continued to broadcast on the 7100 – 7200 kHz frequencies – Eritrea, Sri Lanka, Guinea, Somali, Uganda etc.
