For example, when embedded in text the Morse code sequence represents the "double hyphen" character (normally "=", but also "– –"). [1] When the same code appears alone it indicates the action of spacing down two lines on a page in order to create the white space indicating the start of a new paragraph [ 2 ] or new section in a message ...
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 .
In the following example of a typical casual Morse code conversation between two stations there is extensive use of such: Morse code abbreviations, brevity codes, Morse procedural signs, and other such conventions. An example casual Morse code (CW) conversation between Station S1ABC and Station S2YZ is illustrated in the following paragraphs.
In voice communications certain 'prowords' that are equivalent to the older prosigns for Morse code are in use. For example the proword "OVER" is used in voice communications where the Morse prosign "K" is used in Morse communications. (A reference citation should be added to the article referencing the word "proword".
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 abbreviation is not always a short form of the word used in the clue. For example: "Knight" for N (the symbol used in chess notation) Taking this one stage further, the clue word can hint at the word or words to be abbreviated rather than giving the word itself. For example: "About" for C or CA (for "circa"), or RE.
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 ...
American Morse code. American Morse Code — also known as Railroad Morse—is the latter-day name for the original version of the Morse Code developed in the mid-1840s, by Samuel Morse and Alfred Vail for their electric telegraph. The "American" qualifier was added because, after most of the rest of the world adopted " International Morse Code ...
