BEST SHORTWAVE RADIO STATIONS CODE

They are therefore very useful for checking the accuracy of your receiver. These are stations which use very accurate transmitters controlled by atomic clocks, and thus serve as highly accurate references. The only other short-wave frequencies which it is usually legal to receive and which require no specialist equipment are 'time and frequency standard stations'. It therefore requires specialist receivers to listen to these other services and indeed under some jurisdictions it is illegal to do so, however there is a world of fun to be had on short wave if you have the time and patience. Broadcasters normally use AM (though some are now digital), whereas most of the other users are either digital or use SSB as with the radio hams. There are lots of other short-wave frequencies which are used for all manner of purposes including ship-to-shore communications (maritime), air traffic control (aeronautical), military and defence, weather information and even spy stations and radio pirates. The largest amateur short wave band which includes FM and satellite allocations. One of the most popular bands with lots of world-wide chatter.

BEST SHORTWAVE RADIO STATIONS CODE

Only used for Morse code and digital transmissions. In some countries extends above and below these limits. Strictly speaking not a short-wave band, but a medium-wave one. Radio amateur transmissions are not listed in the database, but the frequencies to listen out on are listed below. Radio hams use morse code (CW) and digital transmission modes as well, which require additional equipment to decode. Using a normal AM receiver, SSB sounds as if someone is talking with several socks stuffed in their mouth. Receiving SSB needs specialist equipment but even relatively low cost receivers will often do the job. Radio Amateurs (fondly referred to as 'hams') use a different set of frequencies to broadcasters and also use a different form of modulation for speech called single side band (SSB) instead of amplitude modulation (AM) used by international broadcasters. Note that on the main web-site, the range of frequencies listed for these bands in the pull-down menu are somewhat wider to ensure that transmissions from any of the aforementioned out-of-band broadcasters are also captured. Little activity other than tests of local digital services. Highest frequency band in common daily use. Restricted to 7300-7400 kHz in the Americas. Restricted to 3950-4000 kHz in Europe, Africa and the Middle East. (Strictly speaking not a short-wave band but a medium wave one!) There are fourteen discrete bands which are allocated by the ITU for broadcasting over the short wave frequency range: Band Most short-wave radio stations are on a 5 kHz raster meaning that their frequency in kHz will either end with a '5' or a '0' (eg 15205 or 6110 kHz). Also remember, radio frequencies below around 12000 kHz work best when it's dark (at night!) and those above around 9000 kHz work best during daylight hours. If you're just tuning around short wave and looking for stations, the official bands are definitely the place to start. However, not all stations stick within the agreed bands, indeed many choose to use frequencies just outside the official bands where there are fewer competing broadcast stations and thus less interference (this is known as 'out-of-band broadcasting'), but most do remain within the agreed limits. The frequencies and bands used for short-wave radio broadcasting are agreed internationally by an agency of the United Nations known as the International Telecommunications Union ( ITU), and all countries should adhere to the ITU's rules.
