Exempel på hur man kan använda MEDIUMWAVE i en mening

• NRK's mediumwave transmitter at Kvitsøy on 1314 kHz used to be widely heard internationally and was one of the most commonly heard trans-Atlantic DX signals in eastern North America.
• Mexican broadcast stations are assigned call signs beginning with "XE" (for mediumwave and shortwave stations) or "XH" (for FM radio and television stations), followed by one and up to five letters and a suffix according to the band in which they broadcast, these suffixes are: "-AM", "-OC" (shortwave or Onda Corta), "-FM" and "-TDT" (Terrestrial Digital Television).
• In early 1979, Simon Cooper, Ellie Buchanan, and David Clouter at the student-run Cambridge University Broadcasting Society founded a radio station which was granted permission to install induction loops around the Cambridge colleges of Churchill and later New Hall, allowing residents to listen to Cambridge University Radio (as it was then known) over a short-range, mono, mediumwave broadcast.
• The mediumwave transmitter at Zadar was at one time one of the most powerful in Europe and at nighttime could be heard throughout most of the continent with JRT (Yugoslav) and later HR (Croatian) programming from Zagreb and Pula.
• When a well-equipped station with its antenna well-located “high and in the clear” is operating during a signal enhancement, astonishing distances can be bridged, momentarily approaching what is regularly possible on shortwave and mediumwave.
• It was one of the most well-regarded gold-formatted stations to come to the British airwaves in the late 1980s and was launched as a response to government disapproval of the simulcasting of radio companies' FM programming on their mediumwave frequencies.
• Radios for shortwave reception generally have higher performance than those intended for the local mediumwave, longwave or FM broadcast band, since dependable reception of shortwave signals requires a radio with increased sensitivity, selectivity, dynamic range and frequency stability.
• The mediumwave transmitter Flevoland (Middengolf Zendstation Flevoland) was a broadcasting facility for medium wave near Zeewolde in the province of Flevoland, Netherlands, situated at 5°25′ E and 52°23′ N.
• This cut listenership as it increased maintenance costs; Televerket made plans to improve Sweden's AM radio network with five new 600 kW mediumwave transmitters and replacing Orlunda with new longwave facilities on the island of Gotland and at Mora.
• Cage aerials have been built in different variants for broadcast stations in the longwave and mediumwave bands.
• In Dossenheim SWR operated a mediumwave broadcast tower until 30 April 2004 for the frequency 711 kHz with a broadcast power of 5 kilowatts.
• In 1979 new transmitters came into service: in Erching for daytime longwave transmission and in 1980/81 in Nordkirchen and Thurnau for mediumwave transmission.
• Wrotham transmitting station, Brookmans Park transmitting station and Droitwich transmitting station – the main radio transmitters serving London on VHF, mediumwave and longwave respectively.
• Daytime propagation is by means of the groundwave mode and on a given path a longwave signal will propagate much further than a mediumwave signal.
• While any radio covering the mediumwave (AM radio) band can be used for DX purposes, serious DXers generally invest in a higher-quality receiver, and often a specialised indoor tuned box loop or outdoor longwire antenna.
• In USA AM broadcasting, presunrise authorization (PSRA) and postsunset authorization (PSSA) are permission from the Federal Communications Commission to broadcast in AM on mediumwave using a power level higher than what would normally be permitted prior to sunrise/after sunset, or in the latter case, provide Class D stations with service into the evening where they would otherwise be required to sign off.
• Birds have tetrachromatic vision, which means that they have four types of cone cells with peak sensitivities to longwave (l), mediumwave (m), shortwave (s), and ultraviolet (uv) or violet (v) light as well as transparent oil droplets made of carotenoid filters (with mainly the pigments galloxanthin, zeaxanthin, and astaxanthin) that refine spectral sensitivities of the l, m, and s cone-types.
