Countries With VLF Transmitters
A country is a distinct part of the world, such as a state, nation, or other political entity. It may be a sovereign state or make up one part of a larger state. For example, the country of Japan is an independent, sovereign state, while the country of Wales is a component of a multi-part sovereign state, the United Kingdom. A country may be a historically sovereign area (such as Korea), a currently sovereign territory with a unified government (such as Senegal), or a non-sovereign geographic region associated with certain distinct political, ethnic, or cultural characteristics (such as the Basque Country). The definition and usage of the word "country" is flexible and has changed over time. ''The Economist'' wrote in 2010 that "any attempt to find a clear definition of a country soon runs into a thicket of exceptions and anomalies." Most sovereign states, but not all countries, are members of the United Nations. The largest country by area is Russia, while the smallest is ...

Marconi Wireless Telegraphy Station (Kahuku, Hawaii)
The Marconi Wireless Telegraphy station is a historic structure on Oahu's North Shore between the towns of Kawela Bay and Kahuku. It was briefly the world's most powerful telegraph station. History Opened in 1914, at a cost of more than one million dollars, the first message was sent from Iolani Palace to Kaimuki. By 1916 messages were being sent to Japan, at a distance of 4,200 miles. A hotel was built to accommodate employees, along with a station master's building and an additional administration building. A library was provided for staff, and the hotel had a full-time Chinese cook. In 1917, the United States took over control of all wireless stations.

In 1924 its chimney was removed, as steam was no longer being ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tsushima Island
is an island of the Japanese archipelago situated in-between the Tsushima Strait and Korea Strait, approximately halfway between Kyushu and the Korean Peninsula. The main island of Tsushima, once a single island, was divided into two in 1671 by the Ōfunakoshiseto canal and into three in 1900 by the Manzekiseto canal. These canals were driven through isthmuses in the center of the island, forming "North Tsushima Island" (Kamino-shima) and "South Tsushima Island" ( Shimono-shima). Tsushima also incorporates over 100 smaller islands, many tiny. The name ''Tsushima'' generally refers to all the islands of the Tsushima archipelago collectively.

VLF Transmitter Woodside
Woodside Omega Transmitter (station G, now Woodside VLF transmitter) near Woodside, Victoria, Australia, was a transmission tower that was completed in 1982 and demolished in 2015. Until its demolition it was the tallest object in the Southern Hemisphere. History In 1977, The United States and Australian governments agreed to establish an OMEGA navigation system in south-eastern Australia. The agreement was extended in 1995, to 30 September 1997. Station G was an Omega transmitter that used an umbrella antenna carried by a tall grounded lattice steel guyed mast. Unlike many of the other Omega Transmitters, Woodside was not a "hot tower," that is, one which is insulated from a ground connection by large ceramic insulators that support the entire weight of the structure. Rather, the tower was electrically insulated from the topmost guys which served as the radiators, similar to the metal radials of an umbrella without cloth covering. The mast simply supported the downward slop ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
