INTRODUCTION
Short Wave (SW)
Your world receiver can receive a number of wavebands. Tuning to the required FM, MW or LW station will soon become a matter of routine, as the stations are always to be found at the same place on the dial and are thus tied to a fixed wavelength and frequency. With short wave this is unfortunately not always the case. Short wave transmitters have to change their wavelengths fairly often. In the short-wave range between 10 and 100-metre wavelength (frequencies of 30-3 MHz resp.) nine bands between 10 and 50 metres are allocated to short-wave broadcasting, with another four bands between 60 and 120 metres for broadcasting in the earth’s tropical areas. The latter are roughly located between the latitudes of 30° north and 30° south, i.e. around the equator. Most shortwave broadcasting bands, indicated in the short-wave table, are allocated for the whole world and can be used for international broadcasting. They are so far the only wavelengths which allow direct radio reception over long distances. So in addition to the broadcasting services, there is a large number of other users of short wave, for example radio amateurs, shipping and aviation, radio navigation etc.
