The QSA code and QRK code are interrelated and complementary signal reporting codes for use in wireless telegraphy (Morse code). An enhanced format, SINPO code, was published in the ITU Radio Regulations, Geneva, 1959, [1] but is longer and unwieldy for use in the fast pace of Morse code communications.
Morse code abbreviations are used to speed up Morse communications by foreshortening textual words and phrases. Morse abbreviations are short forms, representing normal textual words and phrases formed from some (fewer) characters taken from the word or phrase being abbreviated. Many are typical English abbreviations, or short acronyms for ...
In amateur radio, the Q-codes were originally used in Morse code transmissions to shorten lengthy phrases and were followed by a Morse code question mark ( ) if the phrase was a question. Q-codes are commonly used in voice communications as shorthand nouns, verbs, and adjectives making up phrases.
Morse code is a telecommunications method which encodes text characters as standardized sequences of two different signal durations, called dots and dashes, or dits and dahs. [ 3 ][ 4 ] Morse code is named after Samuel Morse, one of the early developers of the system adopted for electrical telegraphy.
The original edition of ACP-131 was published by the U.S. military during the early years [when?] of radio telegraphy for use by radio operators using Morse Code on continuous wave (CW) telegraphy. It became especially useful, and even essential, to wireless radio operators on both military and civilian ships at sea before the development of advanced single-sideband telephony in the 1960s.
Many shortwave listeners printed their own QSL cards to report reception. A QSL card is a written confirmation of either a two-way radiocommunication between two amateur radio or citizens band stations; a one-way reception of a signal from an AM radio, FM radio, television or shortwave broadcasting station; or the reception of a two-way ...
Morse code mnemonics. Morse code mnemonics are systems to represent the sound of Morse characters in a way intended to be easy to remember. Since every one of these mnemonics requires a two-step mental translation between sound and character, none of these systems are useful for using manual Morse at practical speeds.
NATO Phonetic And Morse Code Alphabet, from the US Navy Signalman 3 & 2 training manual, 1996. This table combines the ICAO international spelling alphabet and the ITU International Morse Code. The Allied military phonetic spelling alphabets prescribed the words that are used to represent each letter of the alphabet, when spelling other words out loud, letter-by-letter, and how the spelling ...
