Radiosport
Radiosport (or radio sport) is formal competition among amateur radio operators in any of three amateur radio activities, ARDF, DXing, and Contesting. The Friendship Radiosport Games is an international multi-sport event that includes all three types of radiosport. Since 1977, the International Amateur Radio Union has sponsored the IARU HF World Championship (originally named the IARU Radiosport Championship). The World Radiosport Team Championship is another international competition. Amateur radio contesting The most common use of the term ''radiosport'' is as a synonym for amateur radio contesting (ham radio contesting). Contesting is an activity where amateur radio stations attempt to make as many two-way contacts with other stations as possible, following certain defined parameters of the competition, to maximize a score. At least two specific contests have used the term ''radiosport'' in their event names; the IARU HF World Championship, a worldwide contest spon ...

Friendship Radiosport Games
The Friendship Radiosport Games (FRG) is an international multi-sport event that includes competitions in the various sports collectively referred to as radiosport. The Friendship Radiosport Games began in 1989 as a result of a sister city agreement between Khabarovsk, Russia and Portland, Oregon, United States. Since then, participation has been extended to other sister cities in the Pacific Rim. The Friendship Radiosport Games are generally held in the month of August. The most recent Friendship Radiosport Games were held on August 19–21, 2016, in Portland, Oregon. Planning for the next games in Khabarovsk is starting with a target date of 2018. History The first Friendship Radiosport Games were held in 1989 in Khabarovsk, Russia, which was then still a part of the Soviet Union. The games were organized as a result of the signing of a sister city agreement between the Far Eastern Russia city of Khabarovsk and the city of Portland, Oregon, on the west coast of the Un ...

World Radiosport Team Championship
The World Radiosport Team Championship is an amateur radio competition. Participation is by invitation only. Entry to each quadrennial WRTC requires qualification through high positions in major world radio contests. The main principle of the WRTC is to provide a level playing field for the qualified contestants from around the world to compete against one another using amateur radio stations located in areas with the same propagation terrain and equipped with identical antennas, operating under the keen eyes of qualified referees. Each WRTC event is organised by a volunteer group of Radio Amateurs in the locality where the competition will be held with the help of a standing committee of internationally recognized contesters. The WRTC is the closest thing to a world championship in the sport of radio contesting. In 2018 over 1000 people are involved with a cost of over half a million EurosWRTC2018 web page History The first World Radiosport Team Championship event was held in Jul ...

Contesting
Contesting (also known as ''radiosport'') is a competitive activity pursued by amateur radio operators. In a contest, an amateur radio station, which may be operated by an individual or a team, seeks to contact as many other amateur radio stations as possible in a given period of time and exchange information. Rules for each competition define the amateur radio frequency allocations, amateur radio bands, the mode of communication that may be used, and the kind of information that must be exchanged. The contacts made during the contest contribute to a score by which stations are ranked. Contest sponsors publish the results in magazines and on web sites. Contesting grew out of other amateur radio activities in the 1920s and 1930s. As intercontinental communications with amateur radio became more common, competitions were formed to challenge stations to make as many contacts as possible with amateur radio stations in other countries. Contests were also formed to provide opportu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
International Amateur Radio Union
The International Amateur Radio Union (IARU) is an international confederation of national organisations that allows a forum for common matters of concern to amateur radio operators worldwide, and collectively represents matters to the International Telecommunication Union (ITU). The International Amateur Radio Union was founded in 1925 and, as of July 2021, it is composed of 172 national member societies. History Following an informal meeting in 1924 of representatives from France, Great Britain, Belgium, Switzerland, Italy, Spain, Luxembourg, Canada, and the United States, a plan was formulated to hold an International Amateur Congress in Paris, France, in April 1925. This Congress was held for the purpose of founding an international amateur radio organization. The Congress was attended by representatives of 23 countries in Europe, Americas, and Asia. A constitution for the IARU was adopted on April 17, and the formation of the International Amateur Radio Union was ratified on ...

Call Signs
In broadcasting and radio communications, a call sign (also known as a call name or call letters—and historically as a call signal—or abbreviated as a call) is a unique identifier for a transmitter station. A call sign can be formally assigned by a government agency, informally adopted by individuals or organizations, or even cryptographically encoded to disguise a station's identity. The use of call signs as unique identifiers dates to the landline railroad telegraph system. Because there was only one telegraph line linking all railroad stations, there needed to be a way to address each one when sending a telegram. In order to save time, two-letter identifiers were adopted for this purpose. This pattern continued in radiotelegraph operation; radio companies initially assigned two-letter identifiers to coastal stations and stations onboard ships at sea. These were not globally unique, so a one-letter company identifier (for instance, 'M' and two letters as a Marconi s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Computer Program
A computer program is a sequence or set of instructions in a programming language for a computer to execute. Computer programs are one component of software, which also includes documentation and other intangible components. A computer program in its human-readable form is called source code. Source code needs another computer program to execute because computers can only execute their native machine instructions. Therefore, source code may be translated to machine instructions using the language's compiler. (Assembly language programs are translated using an assembler.) The resulting file is called an executable. Alternatively, source code may execute within the language's interpreter. If the executable is requested for execution, then the operating system loads it into memory and starts a process. The central processing unit will soon switch to this process so it can fetch, decode, and then execute each machine instruction. If the source code is requested for executio ...

Transmission (telecommunications)
In telecommunications, transmission is the process of sending or propagating an analog or digital signal via a medium that is wired, wireless, or fiber-optic. Transmission technologies typically refer to physical layer protocol duties such as modulation, demodulation, line coding, equalization, error control, bit synchronization and multiplexing, but it may also involve higher-layer protocol duties, for example, digitizing an analog signal, and data compression. Transmission of a digital message, or of a digitized analog signal, is known as data transmission. Examples of transmission are the sending of signals with limited duration, for example, a block or packet of data, a phone call, or an email. See also *Radio transmitter In electronics and telecommunications, a radio transmitter or just transmitter is an electronic device which produces radio waves with an antenna. The transmitter itself generates a radio frequency alternating current, which is appli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Morse Code
Morse code is a method used in telecommunication to encode text characters as standardized sequences of two different signal durations, called ''dots'' and ''dashes'', or ''dits'' and ''dahs''. Morse code is named after Samuel Morse, one of the inventors of the telegraph. International Morse code encodes the 26 basic Latin letters through , one accented Latin letter (), the Arabic numerals, and a small set of punctuation and procedural signals ( prosigns). There is no distinction between upper and lower case letters. Each Morse code symbol is formed by a sequence of ''dits'' and ''dahs''. The ''dit'' duration is the basic unit of time measurement in Morse code transmission. The duration of a ''dah'' is three times the duration of a ''dit''. Each ''dit'' or ''dah'' within an encoded character is followed by a period of signal absence, called a ''space'', equal to the ''dit'' duration. The letters of a word are separated by a space of duration equal to three ''dits' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
