Exempel på hur man kan använda SHORTWAVE i en mening

• In 1998, radio stations were broadcast on AM 2, FM 14 (including 6 repeaters) and shortwave 6 (including 5 repeaters).
• domestic: Majuro Atoll and Ebeye and Kwajalein islands have regular, seven-digit, direct-dial telephones; other islands interconnected by shortwave radio, telephone (used mostly for government purposes).
• AM 1, FM 0, shortwave 0 (2011) - The Tuvalu Media Department of the Government of Tuvalu operates Radio Tuvalu, which broadcasts on the AM frequency.
• It broadcasts radio news, speech and discussions in more than 40 languages to many parts of the world on analogue and digital shortwave platforms, internet streaming, podcasting, satellite, DAB, FM, LW and MW relays.
• Suppressed carriers are often used for single sideband (SSB) transmissions, such as for amateur radio on shortwave.
• Since SSTV systems operate on voice frequencies, amateurs use it on shortwave (also known as HF by amateur radio operators), VHF and UHF radio.
• Radio waves in the shortwave band can be reflected or refracted from a layer of electrically charged atoms in the atmosphere called the Ionosphere.
• Additionally, frequencies in the shortwave bands between approximately 1 and 30 MHz, can be refracted back to Earth by the ionosphere, called skywave or "skip" propagation, thus giving radio transmissions in this range a potentially global reach.
• The CBC operates four terrestrial radio networks: The English-language CBC Radio One and CBC Music, and the French-language Ici Radio-Canada Première and Ici Musique (international radio service Radio Canada International historically transmitted via shortwave radio, but since 2012 its content is only available as podcasts on its website).
• Radio broadcast stations: AM 0, FM 1, shortwave 0 (easy access to radio and television broadcasts originating in France and Spain) (2007).
• Citizens band radio (CB radio) is a land mobile radio system, a system allowing short-distance one-to-many bidirectional voice communication among individuals, using two-way radios operating near 27 MHz (or the 11-m wavelength) in the high frequency or shortwave band.
• Privately controlled shortwave networks included the National Broadcasting Company's International Network (or White Network), which broadcast in six languages, the Columbia Broadcasting System's Latin American international network, which consisted of 64 stations located in 18 countries, the Crosley Broadcasting Corporation in Cincinnati, Ohio, and General Electric which owned and operated WGEO and WGEA, both based in Schenectady, New York, and KGEI in San Francisco, all of which had shortwave transmitters.
• NHK World-Japan is composed of NHK World TV, NHK World Premium, and the shortwave radio service Radio Japan (RJ).
• According to James Kasting, planets whose atmospheres do not absorb shortwave sunlight, such as Venus and Mars, do not have a Stratosphere and thus have no Stratopause.
• While on intelligence duty he intercepted a shortwave radio message in plain English that 17 troop transports were en route to England, having cleared the port of Freetown, Sierra Leone.
• Finally, when only part of a sideband is attenuated (as often happens to skywave signals reflecting off the ionosphere), an effect known as selective fading, very unpleasant effects result; hence, the C-QUAM system is not often if ever used for shortwave broadcasting, nor by stations which receive a great deal of skywave interference.
• Suppressed-carrier ISB was employed in point-to-point (usually overseas) radiotelephony and radioteletype by shortwave (HF).
• As a result of skywave propagation, a signal from a distant AM broadcasting station, a shortwave station, or – during sporadic E propagation conditions (principally during the summer months in both hemispheres) – a distant VHF FM or TV station can sometimes be received as clearly as local stations.
• It was inaugurated by the Australian Post Office at Lyndhurst, Victoria on 21 September 1964, although a predecessor service using the callsign VLX had begun in March 1946 alongside shortwave radio station VLR.
• In July 1936, the network broadcast live coverage from France of the unveiling by King Edward VIII of the Canadian National Vimy Memorial, which was relayed across the ocean by shortwave radio.
