The only difference between what is transmitted for the Morse code prosign vs. the separate letter signs is the presence or absence of an inter-letter space between the two "dit" / "dah" sequences. Although the difference in the transmission is subtle, the difference in meaning is gross:
Morse code. 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 .
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 ...
Yep 100% agree Pete. As anyone who can send & receive morse code knows, it's letters are sounds. A Prosign, by definition, is a unique sound which is only represented by the written gylphs of the Prosign. This is why AR can also be written RN. Those sounds, are the code, not the representation of them.
For example: "Mayday, Mayday, Mayday, Wiki Air 999, we have lost both of our engines due to a bird strike, we are gliding now." After that pilot can give, or the controller can ask for, additional information, such as, fuel and number of passengers on board.
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. Amateur radio clubs can provide resources to ...
The Q-code is a standardised collection of three-letter codes that each 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 ...
In modern terminology, SOS is a Morse "procedural signal" or "prosign ", [3] used as a start-of-message mark for transmissions requesting assistance when loss of life or catastrophic loss of property is imminent. [4] Other prefixes are used for mechanical breakdowns, requests for medical assistance, and a relayed distress signal originally sent ...
