DXpedition
A DX-pedition is an expedition to what is considered an exotic place by amateur radio operators and DX listeners, typically because of its remoteness, access restrictions, or simply because there are very few radio amateurs active from that place. This could be an island, a country, or even a particular spot on a geographical grid. ''DX'' is a telegraphic shorthand for "distance" or "distant" (see DXing). History Early DX-peditions were simply exploratory and geographical expeditions in the late 1920s and 1930s, in which one or more radio amateurs participated to provide long-distance communications. At the same time they communicated with fellow radio amateurs who wanted to contact a new country. Most notable are the Antarctic expeditions of Admiral Byrd. Another example is the voyage of the schooner ''Kaimiloa'', which traveled the South Pacific in 1924. While the ship's wealthy owners enjoyed the islands, an amateur radio operator kept contact with, and sent QSL cards to, e ...

Clipperton Island
Clipperton Island ( or ; ) is an uninhabited, coral atoll in the eastern Pacific Ocean. It is from Paris, France, from Papeete, Tahiti, and from Mexico. It is an overseas state private property of France under direct authority of the Minister of the Overseas. In the past, Clipperton Island was the subject of a sovereignty dispute in particular between France and Mexico, which was finally settled through arbitration in 1931; the ''Clipperton Island Case'' remains widely studied in international law textbooks. Geography The atoll is south-west of Mexico, west of Nicaragua, west of Costa Rica and north-west of the Galápagos Islands, Ecuador, at . Clipperton is about south-east of Socorro Island in the Revillagigedo Archipelago, which is the nearest land, while the nearest French-owned island is Hiva Oa. Some consider it to be one of the eastern-most points of Oceania, rather than an outlying island of the Americas. It is low-lying and largely barren, with some sca ...

Campbell Island, New Zealand
Campbell Island / Motu Ihupuku is an uninhabited subantarctic island of New Zealand, and the main island of the Campbell Island group. It covers of the group's , and is surrounded by numerous stacks, rocks and islets like Dent Island, Folly Island (or Folly Islands), Isle de Jeanette-Marie, and Jacquemart Island, the latter being the southernmost extremity of New Zealand. The island is mountainous, rising to over in the south. A long fiord, Perseverance Harbour, nearly bisects it, opening out to sea on the east coast. The island is listed with the New Zealand Outlying Islands. The island is an immediate part of New Zealand, but not part of any region or district, but instead ''Area Outside Territorial Authority'', like all other outlying islands, other than the Solander Islands. It is the closest piece of land to the antipodal point of the United Kingdom, and Ireland, meaning that the furthest away city is Limerick, Ireland. Campbell Island is a UNESCO World Heritag ...

Navassa Island
Navassa Island (; ht, Lanavaz; french: l'île de la Navasse, sometimes ) is a small uninhabited island in the Caribbean Sea. Located northeast of Jamaica, south of Cuba, and west of Jérémie on the Tiburon Peninsula of Haiti, it is subject to an ongoing territorial dispute between Haiti and the United States, which administers the island through the U.S. Fish and Wildlife Service. The U.S. has claimed the island, as an appurtenance, since 1857, based on the Guano Islands Act of 1856. Haiti's claim over Navassa goes back to the Treaty of Ryswick in 1697 that established French possessions on mainland Hispaniola from Spain, as well as other specifically named nearby islands. However, there was no mention of Navassa in the treaty detailing terms. Haiti's 1801 constitution claimed several nearby islands by name, among which Navassa was not listed, but also laid claim to "other adjacent islands", which Haiti maintains included Navassa. The U.S. claim to the island, first made i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
DXing
DXing is the hobby of receiving and identifying distant radio or television signals, or making two-way radio contact with distant stations in amateur radio, citizens' band radio or other two-way radio communications. Many DXers also attempt to obtain written verifications of reception or contact, sometimes referred to as " QSLs" or "veries". The name of the hobby comes from DX, telegraphic shorthand for "distance" or "distant". The practice of DXing arose during the early days of radio broadcasting. Listeners would mail "reception reports" to radio broadcasting stations in hopes of getting a written acknowledgement or a QSL card that served to officially verify they had heard a distant station. Collecting these cards became popular with radio listeners in the 1920s and 1930s, and reception reports were often used by early broadcasters to gauge the effectiveness of their transmissions. Although international shortwave broadcasts are on the decline, DXing remains popular among de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Peter I Island
Peter I Island ( no, Peter I Øy) is an uninhabited volcanic island in the Bellingshausen Sea, from continental Antarctica. It is claimed as a dependency of Norway and, along with Bouvet Island and Queen Maud Land, composes one of the three Norwegian dependent territories in the Antarctic and Subantarctic. The island measures approximately , with an area of ; its highest point is the ultra-prominent, Lars Christensen Peak. Nearly all the island is covered by a glacier, and it is surrounded most of the year by pack ice, making it inaccessible during these times. There is little vertebrate animal life on the island, apart from some seabirds and seals. The island was first sighted by Fabian Gottlieb von Bellingshausen on 21 January 1821 and was named for Peter I of Russia. Not until 2 February 1929 did anyone set foot on the island, when Nils Larsen and Ola Olstad's Second ''Norvegia'' Expedition, financed by Lars Christensen, was successful. They claimed it for Norway, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mount Athos
Mount Athos (; el, Ἄθως, ) is a mountain in the distal part of the eponymous Athos peninsula and site of an important centre of Eastern Orthodox monasticism in northeastern Greece. The mountain along with the respective part of the peninsula have been governed as the monastic community of Mount Athos, an autonomous region within the Hellenic Republic, ecclesiastically under the direct jurisdiction of the Ecumenical Patriarch of Constantinople, while the remainder of the peninsula forms part of the Aristotelis municipality. Mount Athos has been inhabited since ancient times and is known for its long Christian presence and historical monastic traditions, which date back to at least AD 800 and the Byzantine era. Because of its long history of religious importance, the well-preserved agrarian architecture within the monasteries, and the preservation of the flora and fauna around the mountain, Mount Athos was inscribed on the UNESCO World Heritage List in 1988. In modern Gr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
North Korea
North Korea, officially the Democratic People's Republic of Korea (DPRK), is a country in East Asia. It constitutes the northern half of the Korean Peninsula and shares borders with China and Russia to the north, at the Yalu (Amnok) and Tumen rivers, and South Korea to the south at the Korean Demilitarized Zone.

Maidenhead Locator
The Maidenhead Locator System (a.k.a. QTH Locator and IARU Locator) is a geocode system used by amateur radio operators to succinctly describe their geographic coordinates, which replaced the deprecated QRA locator, which was limited to European contacts. Its purpose is to be concise, accurate, and robust in the face of interference and other adverse transmission conditions. The ''Maidenhead Locator System'' can describe locations anywhere in the world. Maidenhead locators are also commonly referred to as ''QTH locators'', ''grid locators'' or ''grid squares'', although the "squares" are distorted on any non- equirectangular cartographic projection. Use of the terms ''QTH locator'' and ''QRA locator'' was initially discouraged, as it caused confusion with the older QRA locator system. The only abbreviation recommended to indicate a Maidenhead reference in Morse code and radio teleprinter transmission was LOC, as in LOC KN28LH. John Morris G4ANB originally devised the system a ...
