- Shortwave_radio abstract "Shortwave radio (as the name implies) refers to radio transmissions using shortwave frequencies. The widest popular definition of the shortwave frequency interval is the ITU Region 1 (EU+Africa+Russia...) definition, and is the span 1.6–30 MHz. ca. 1.6 MHz is just above medium wave.There are also other definitions of the shortwave frequency interval: 1710 kHz to 30 MHz in ITU Region 2 (north- and south-america...) 1800 kHz (160 meter radio amateur band start) to 30 MHz 2300 kHz (120 meter band start) to 30 MHz 2300 kHz (120 meter band start) to 26.1 MHz (11 meter band end) In Germany and maybe Austria the ITU region 1 shortwave frequency interval can be subdivided in: de:Grenzwelle ("boarder waves"): 1.605-3.8 MHz and de:Kurzwelle (shortwaves) 3.8-30MHz Grenzwelle: 1.605-4 MHz and Kurzwelle (shortwaves) 4-30MHz In Germany these shortwave frequency intervals has also been seen used: 3-30MHz - e.g. some could believe that the shortwave_frequency_interval=high_frequency, but in reality the shortwave frequency interval is a mess, and therefore the shortwave frequency interval can not be exactly equal high frequency. the above other definitionsShortwave radio received its name because the wavelengths in this band are shorter than 200 m (1500 kHz) which marked the original upper limit of the medium frequency band first used for radio communications. The broadcast medium wave band now extends above the 200 m/1500 kHz limit, and the amateur radio 1.8 MHz – 2.0 MHz band (known as the "top band") is the lowest-frequency band considered to be 'shortwave'.Initially thought to be useless, shortwave radio is used for long distance communication by means of skywave or skip propagation, in which the radio waves are reflected back to Earth from the ionosphere, allowing communication around the curve of the Earth. Shortwave radio is used for broadcasting of voice and music, and long-distance communication to ships and aircraft, or to remote areas out of reach of wired communication or other radio services. Additionally, it is used for two-way international communication by amateur radio enthusiasts for hobby, educational and emergency purposes.".
