Rás 1 (2011)
Rás 1 (; ''Channel 1'') is an Icelandic radio station belonging to and operated by Ríkisútvarpið (RÚV), Iceland's national public service broadcaster. Broadcast throughout Iceland on FM (92.4 and 93.5 MHz in Reykjavík), via satellite, DVB and also 189 kHz longwave, it is currently among the country's most listened-to radio stations. History The station began broadcasts on 20 December 1930, using the call-sign Útvarp Reykjavík (Radio Reykjavík). A transmission site was chosen at Vatnsendi (also known as Vatnsendahæð) in Kópavogur, then uninhabited, due to its prominence over Reykjavik as well as its relatively flat land. Two 150 metre tall steel masts made by Telefunken were erected and a wire strung between them forming a T-antenna. As was the norm for the time, broadcasts were on AM longwave band, initially at a wavelength of 1200 metres (249.8 kHz) with a power of 16kW. Marconi transmission equipment was used. New transmission equipment was acqui ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
T-antenna
A T-antenna, T-aerial, flat-top antenna, or (capacitively) top-loaded antenna is a monopole radio antenna with transverse capacitive loading wires attached to its top. T-antennas are typically used in the VLF, LF, MF, and shortwave bands, and are widely used as transmitting antennas for amateur radio stations, and long wave and medium wave AM broadcasting stations. They can also be used as receiving antennas for shortwave listening. The antenna consists of one or more horizontal wires suspended between two supporting radio masts or buildings and insulated from them at the ends. A vertical wire is connected to the center of the horizontal wires and hangs down close to the ground, connected to the transmitter or receiver. Combined, the two sections form a ‘T’ shape, hence the name. The transmitter power is applied, or the receiver is connected, between the bottom of the vertical wire and a ground connection. The T-antenna functions as a monopole antenna with capaci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sailor
A sailor, seaman, mariner, or seafarer is a person who works aboard a watercraft as part of its crew, and may work in any one of a number of different fields that are related to the operation and maintenance of a ship. The profession of the sailor is old, and the term ''sailor'' has its etymological roots in a time when sailing ships were the main mode of transport at sea, but it now refers to the personnel of all watercraft regardless of the mode of transport, and encompasses people who operate ships professionally, be it for a military navy or civilian merchant navy, as a sport or recreationally. In a navy, there may be further distinctions: ''sailor'' may refer to any member of the navy even if they are based on land; while ''seaman'' may refer to a specific enlisted rank. Professional mariners Seafarers hold a variety of professions and ranks, each of which carries unique responsibilities which are integral to the successful operation of an ocean-going vessel. A shi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shortwave Radio
Shortwave radio is radio transmission using shortwave (SW) radio frequencies. There is no official definition of the band, but the range always includes all of the high frequency band (HF), which extends from 3 to 30 MHz (100 to 10 metres); above the medium frequency band (MF), to the bottom of the VHF band. Radio waves in the shortwave band can be reflected or refracted from a layer of electrically charged atoms in the atmosphere called the ionosphere. Therefore, short waves directed at an angle into the sky can be reflected back to Earth at great distances, beyond the horizon. This is called skywave or "skip" propagation. Thus shortwave radio can be used for communication over very long distances, in contrast to radio waves of higher frequency, which travel in straight lines (line-of-sight propagation) and are limited by the visual horizon, about 64 km (40 miles). Shortwave broadcasts of radio programs played an important role in the early days of radi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Loran-C
Loran-C is a hyperbolic radio navigation system that allows a receiver to determine its position by listening to low frequency radio signals that are transmitted by fixed land-based radio beacons. Loran-C combined two different techniques to provide a signal that was both long-range and highly accurate, features that had been incompatible. Its disadvantage was the expense of the equipment needed to interpret the signals, which meant that Loran-C was used primarily by militaries after it was introduced in 1957. By the 1970s, the cost, weight and size of electronics needed to implement Loran-C had been dramatically reduced because of the introduction of solid-state electronics and, from the mid-1970s, early microcontrollers to process the signal. Low-cost and easy-to-use Loran-C units became common from the late 1970s, especially in the early 1980s, and the earlier LORAN system was discontinued in favor of installing more Loran-C stations around the world. Loran-C became one ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Civil Defense
Civil defense ( en, region=gb, civil defence) or civil protection is an effort to protect the citizens of a state (generally non-combatants) from man-made and natural disasters. It uses the principles of emergency operations: prevention, mitigation, preparation, response, or emergency evacuation and recovery. Programs of this sort were initially discussed at least as early as the 1920s and were implemented in some countries during the 1930s as the threat of war and aerial bombardment grew. Civil-defense structures became widespread after authorities recognised the threats posed by nuclear weapons. Since the end of the Cold War, the focus of civil defense has largely shifted from responding to military attack to dealing with emergencies and disasters in general. The new concept is characterised by a number of terms, each of which has its own specific shade of meaning, such as '' crisis management'', ''emergency management'', ''emergency preparedness'', ''contingency plannin ...

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. The hertz is an SI derived unit whose expression in terms of SI base units is s−1, meaning that on ... at a powe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Höfn
Höfn () or Höfn í Hornafirði () is an Icelandic fishing town in the southeastern part of the country. It lies near Hornafjörður fjord. The town, the second largest in the southeastern part of Iceland, offers scenic views of Vatnajökull (the largest ice cap in Europe by volume). The community was formerly known as Hornafjarðarbær between 1994 and 1998. Geography Höfn is located on a peninsula in the southeast of Iceland. The name Höfn means harbour and it is a fishing port surrounded on three sides by the sea, with beaches on a long shoreline to the southeast. Shoals and glacial rivers traverse this area with many shifting lagoons and sand reefs being formed. Höfn is surrounded by several small islands to the east of the town, the largest of which is Mikley , followed by Krókalátur and Hellir .

Akureyri
Akureyri (, locally ) is a town in northern Iceland. It is Iceland's fifth-largest municipality, after Reykjavík, Hafnarfjörður, Reykjanesbær and Kópavogur, and the largest town outside Iceland's more populated southwest corner. Nicknamed the "Capital of North Iceland", Akureyri is an important port and fishing centre. The area where Akureyri is located was settled in the 9th century, but did not receive a municipal charter until 1786. Allied units were based in the town during World War II. Further growth occurred after the war as the Icelandic population increasingly moved to urban areas. The area has a relatively mild climate because of geographical factors, and the town's ice-free harbour has played a significant role in its history. History The Norse Viking Helgi ''magri'' (the slim) Eyvindarson originally settled the area in the 9th century. The first mention of Akureyri is in court records from 1562, when a woman was sentenced there for adultery. In the 17th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Althing
The Alþingi (''general meeting'' in Icelandic, , anglicised as ' or ') is the supreme national parliament of Iceland. It is one of the oldest surviving parliaments in the world. The Althing was founded in 930 at (" thing fields" or "assembly fields"), situated approximately east of what later became the country's capital, Reykjavík. Even after Iceland's union with Norway in 1262, the Althing still held its sessions at until 1800, when it was discontinued. It was restored in 1844 by royal decree and moved to Reykjavík. The restored unicameral legislature first came together in 1845 and after 1874 operated in two chambers with an additional third chamber taking on a greater role as the decades passed until 1991 when Althing became once again unicameral. The present parliament building, the , was built in 1881, made of hewn Icelandic stone. The unicameral parliament has 63 members, and is elected every four years based on party-list proportional representation. The c ...
