A number of phonetic alphabets exist. The NATO version is most common and can be considered to be the "international" phonetic alphabet. Main articles: morse codeWikipedia:Morse code.
Amateur radio actually has adapted two different sets of Q codes for use in amateur communications. Most of the meanings are identical to the ITU definitions, however, they must be looked at in the context of amateur communications. For example, QSJ?
Marine, amateur and CB radio. This information, about the operating procedures for the amateur service, can help prospective amateur operators studying for amateur exams. Emission classifications provide an internationally recognised standard by which to specify, accurately and concisely, the significant characteristics of a transmission.
Radio amateur activities Traffic and Codes. To understand the amateur radio "language" you have to learn the famous "Q-code" as well as the "radio" alphabet Alpha, Bravo, Charlie You will find hereunder the complete Q-code from which has been excluded most codes used in the aviation and maritime traffics, the radio alphabet, the RST report, the SINPO code, some useful acronyms without to forget the Morse code.
Below a number of Q signals are listed whose meanings most often need to be expressed with brevity and clarity in amateur radio work. Q signals take the form of a question only when each is sent followed by a question mark. QRB How far are you from my station?
The Q-code is an international set of abbreviations that was created at the beginning of the last century to simplify radiotelegraph communication. Each code is composed by three letters always starting with Q. Each code can be a question if followed by a question mark or an answer or statement if not.
The International Q Code system is an abbreviated way to exchange a great deal of information with a simple code. This was initially used in Amateur Radio during Morse Code transmissions, so standard short codes could simplify the transfer of information. The Q Code consists of three-letter groups with each group having a specific meaning.
The Q-code is a standardized collection of three-letter codes all of which start with the letter "Q". It is an operating signal initially developed for commercial radiotelegraph communication and later adopted by other radio services, especially amateur radio. To distinguish the use of a Q-code transmitted as a question from the same Q-code transmitted as a statement, operators either prefixed it with the military network question marker " INT " dit dit dah dit dah or suffixed it with the standard Morse question mark UD dit dit dah dah dit dit. Although Q-codes were created when radio used Morse code exclusively, they continued to be employed after the introduction of voice transmissions.
The Q code is a standardized collection of three-letter message encodings, also known as a brevity code, all of which start with the letter "Q", initially developed for commercial radiotelegraph communication, and later adopted by other radio services, especially amateur radio. Although Q codes were created when radio used Morse code exclusively, they continued to be employed after the introduction of voice transmissions. To avoid confusion, transmitter call signs are restricted; while an embedded three-letter Q sequence may occur for instance when requested by an amateur radio station dedicated to low-power operationno country is ever issued an ITU prefix starting with "Q".
