Proword
Procedure words (abbreviated to prowords) are words or phrases limited to radio telephone procedure used to facilitate communication by conveying information in a condensed standard verbal format. Prowords are voice versions of the much older procedural signs for Morse code which were first developed in the 1860s for Morse telegraphy, and their meaning is identical. The NATO communications manual ACP-125 contains the most formal and perhaps earliest modern (post-World War II) glossary of prowords, but its definitions have been adopted by many other organizations, including the United Nations Development Programme, the U.S. Coast Guard, US Civil Air Patrol, US Military Auxiliary Radio System, and others. Prowords are one of several structured parts of radio voice procedures, including brevity codes and plain language radio checks. Examples According to the U.S. Marine Corps training document FMSO 108, "understanding the following PROWORDS and their respective definitions i ...

Signal Strength And Readability Report
A signal strength and readability report is a standardized format for reporting the strength of the radio signal and the readability (quality) of the radiotelephone (voice) or radiotelegraph (Morse code) signal transmitted by another station as received at the reporting station's location and by their radio station equipment. These report formats are usually designed for only one communications mode or the other, although a few are used for both telegraph and voice communications. All but one of these signal report formats involve the transmission of numbers. History As the earliest radio communication used Morse code, all radio signal reporting formats until about the 1920s were for radiotelegraph, and the early voice radio signal report formats were based on the telegraph report formats. Timeline of signal report formats * The first signal report format code may have been QJS. * The U.S. Navy used R and K signals starting in 1929. * The QSK code was one of the twelve Q Co ...

Plain Language Radio Checks
A plain-language radio check is the means of requesting and giving a signal strength and readability report for radiotelephony (voice) communications, and is the direct equivalent to the QSA and QRK code used to give the same report in radiotelegraph ( Morse code) communications. SINPEMFO code is the voice signal reporting format developed by the ITU in 1959, but sees little use outside of shortwave listeners. Allied Communications Procedure 125(F), Communication Instructions Radiotelephone Procedure, published by the Combined Communication Electronics Board, defines radiotelephone procedures, and contains the original definitions for many common radio communications procedures, including Procedure Words, radio net operations, etc. Section 611 of ACP 125(F) details how to conduct radio checks using plain language. Radio check procedure The prowords listed below are for use when initiating and answering queries concerning signal strength and readability. Signal strength proword ...

NATO Phonetic Alphabet
The (International) Radiotelephony Spelling Alphabet, commonly known as the NATO phonetic alphabet, is the most widely used set of clear code words for communicating the letters of the Roman alphabet, technically a ''radiotelephonic spelling alphabet.'' It goes by various names, including NATO spelling alphabet, ICAO phonetic alphabet and ICAO spelling alphabet. The ITU phonetic alphabet and figure code is a rarely used variant that differs in the code words for digits. To create the code, a series of international agencies assigned 26 code words acrophonically to the letters of the Roman alphabet, with the intention of the letters and numbers being easily distinguishable from one another over radio and telephone, regardless of language barriers and connection quality. The specific code words varied, as some seemingly distinct words were found to be ineffective in real-life conditions. In 1956, NATO modified the then-current set of code words used by the International ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spelling Alphabet
A spelling alphabet ( also called by various other names) is a set of words used to represent the letters of an alphabet in oral communication, especially over a two-way radio or telephone. The words chosen to represent the letters sound sufficiently different from each other to clearly differentiate them. This avoids any confusion that could easily otherwise result from the names of letters that sound similar, except for some small difference easily missed or easily degraded by the imperfect sound quality of the apparatus. For example, in the Latin alphabet, the letters B, P, and D ("bee", "pee" and "dee") sound similar and could easily be confused, but the words "bravo", "papa" and "delta" sound completely different, making confusion unlikely. Any suitable words can be used in the moment, making this form of communication easy even for people not trained on any particular standardized spelling alphabet. For example, it is common to hear a nonce form like "A as in 'apple', D as in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prosigns For Morse Code
Procedural signs or prosigns are shorthand signals used in Morse code radio telegraphy procedure, for the purpose of simplifying and standardizing radio communication protocol. They are separate from Morse code abbreviations, which consist mainly of brevity codes that convey messages to other parties with greater speed and accuracy. In general prosigns are just standardised parts of short form radio protocol, and can include any abbreviation. An example would be K for "okay, heard you, continue". In a more limited role the term refers to something akin to that of the nonprinting control characters in teleprinter and computer character sets, such as Baudot or ASCII. Different from abbreviations, those are universally recognizable across language barriers as distinct and well-defined symbols. At the coding level, prosigns admit any form the Morse code can take, unlike abbreviations which have to follow letter form. Many of them are longer than typical characters and are rendere ...

Radio Telephone
Radio is the technology of signaling and communicating using radio waves. Radio waves are electromagnetic waves of frequency between 30 hertz (Hz) and 300 gigahertz (GHz). They are generated by an electronic device called a transmitter connected to an antenna which radiates the waves, and received by another antenna connected to a radio receiver. Radio is very widely used in modern technology, in radio communication, radar, radio navigation, remote control, remote sensing, and other applications. In radio communication, used in radio and television broadcasting, cell phones, two-way radios, wireless networking, and satellite communication, among numerous other uses, radio waves are used to carry information across space from a transmitter to a receiver, by modulating the radio signal (impressing an information signal on the radio wave by varying some aspect of the wave) in the transmitter. In radar, used to locate and track objects like aircraft, ships, spacecraf ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Solent
The Solent ( ) is a strait between the Isle of Wight and Great Britain. It is about long and varies in width between , although the Hurst Spit which projects into the Solent narrows the sea crossing between Hurst Castle and Colwell Bay to just over . The Solent is a major shipping lane for passenger, freight and military vessels. It is an important recreational area for water sports, particularly yachting, hosting the Cowes Week sailing event annually. It is sheltered by the Isle of Wight and has a complex tidal pattern, which has benefited Southampton's success as a port, providing a "double high tide" that extends the tidal window during which deep-draught ships can be handled. Portsmouth lies on its shores. Spithead, an area off Gilkicker Point near Gosport, is known as the place where the Royal Navy is traditionally reviewed by the monarch of the day. The area is of great ecological and landscape importance, particularly because of the coastal and estuarine habi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fire Discipline
Fire discipline is a system of communication in the military, primarily for directing artillery. By definition, fire discipline is the language of fire control. It consists of words, phrases, rules, and conventions which have specific meanings and which result in some definite action being taken with the guns. All ranks concerned in fire control must be thoroughly familiar with the language and the resulting actions. The aim of fire discipline is to ensure that in response to calls for fire (from a forward observer), the appropriate action is taken at the FPC (future planning cell), FSCC (fire support coordination center), FDC (fire direction center) and at the Guns/MRL, strictly in accordance with the intentions of the originator and with the minimum of delay. Six elements of a call for fire An initial call for fire (to an artillery battery) consists of six elements: *Observer identification *Warning order *Target location *Target description *Method of engagement *Method ...

Call Sign
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 sta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
