Eiðar Longwave Transmitter
The Eiðar longwave transmitter was a facility previously used by RÚV (the Icelandic National Broadcasting Service) for longwave radio broadcasting on 207 kHz with a power of 100 kW. The transmitter was situated at Eiðar near Egilsstaðir in East Iceland. It was demolished in March 2023. At the time of its closure, it used an omnidirectional aerial in the form of a tall steel lattice mast radiator insulated against the ground. The transmission site was in use from 1938 until its closure in 2023. Along with the more powerful Hellissandur longwave transmitter, it formed RÚV's longwave service. It was intended to fill in gaps of the FM radio, serve seafarers and act as a critical communications facility. History The first transmission towers at Eiðar were built in 1938, consisting of two masts forming a T-antenna. Eiðar first broadcast on medium-wave, with a power of 1 kW. This was later increased to 5 kW with new equipment in 1950. In 1951, the origi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
RÚV
Ríkisútvarpið (RÚV) (pronounced or ) ( en, 'The Icelandic National Broadcasting Service') is Iceland's national public-service broadcasting organization. Operating from studios in the country's capital, Reykjavík, as well as regional centres around the country, the service broadcasts an assortment of general programming to a wide national audience via three radio stations: Rás 1 and Rás 2, also available internationally; Rondó (only available via the Internet and digital radio); and one full-time television channel of the same name. There is also a supplementary, part-time TV channel, RÚV 2, which transmits live coverage of major cultural and sporting events, both domestic and foreign, as required. History RÚV began radio broadcasting in 1930 and its first television transmissions were made in 1966. In both cases coverage quickly reached nearly every household in Iceland. RÚV is funded by a broadcast receiving licence fee collected from every income tax payer, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Longwave
In radio, longwave, long wave or long-wave, and commonly abbreviated LW, refers to parts of the radio spectrum with wavelengths longer than what was originally called the medium-wave broadcasting band. The term is historic, dating from the early 20th century, when the radio spectrum was considered to consist of longwave (LW), medium-wave (MW), and short-wave (SW) radio bands. Most modern radio systems and devices use wavelengths which would then have been considered 'ultra-short'. In contemporary usage, the term ''longwave'' is not defined precisely, and its intended meaning varies. It may be used for radio wavelengths longer than 1,000 m i.e. frequencies up to 300 kilohertz (kHz), including the International Telecommunication Union's (ITU's) low frequency (LF, 30–300 kHz) and very low frequency (VLF, 3–30 kHz) bands. Sometimes the upper limit is taken to be higher than 300 kHz, but not above the start of the medium wave broadcast band at 520&nb ...

Hellissandur Longwave Radio Mast
The Hellissandur longwave radio mast ( is, Langbylgjustöðin á Gufuskálum ) is a 412-metre-high guyed radio mast used for longwave radio transmissions, and situated at , near Hellissandur on the Snæfellsnes peninsula of Iceland. The mast, which is among the tallest structures in Western Europe, is insulated against the ground, and guyed at five levels by steel ropes, which are subdivided by insulators. It was built in 1963 to replace the 190.5-metre-high LORAN-C mast, constructed in 1959 for the North Atlantic LORAN-C chain (GRD 7970). After the closure of the LORAN-C scheme in 1994, the mast was converted for use by RÚV (The Icelandic National Broadcasting Service) for its longwave transmissions on 189 kHz The hertz (symbol: Hz) is the unit of frequency in the International System of Units (SI), equivalent to one event (or cycle) per second.

Medium Wave
Medium wave (MW) is the part of the medium frequency (MF) radio band used mainly for AM radio broadcasting. The spectrum provides about 120 channels with more limited sound quality than FM stations on the FM broadcast band. During the daytime, reception is usually limited to more local stations, though this is dependent on the signal conditions and quality of radio receiver used. Improved signal propagation at night allows the reception of much longer distance signals (within a range of about 2,000 km or 1,200 miles). This can cause increased interference because on most channels multiple transmitters operate simultaneously worldwide. In addition, amplitude modulation (AM) is often more prone to interference by various electronic devices, especially power supplies and computers. Strong transmitters cover larger areas than on the FM broadcast band but require more energy and longer antennas. Digital modes are possible but have not reached momentum yet. MW was the main radio ban ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Broadcast Transmitters
Broadcasting is the distribution of audio or video content to a dispersed audience via any electronic mass communications medium, but typically one using the electromagnetic spectrum (radio waves), in a one-to-many model. Broadcasting began with AM radio, which came into popular use around 1920 with the spread of vacuum tube radio transmitters and receivers. Before this, all forms of electronic communication (early radio, telephone, and telegraph) were one-to-one, with the message intended for a single recipient. The term ''broadcasting'' evolved from its use as the agricultural method of sowing seeds in a field by casting them broadly about. It was later adopted for describing the widespread distribution of information by printed materials or by telegraph. Examples applying it to "one-to-many" radio transmissions of an individual station to multiple listeners appeared as early as 1898. Over the air broadcasting is usually associated with radio and television, though more r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
