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 ...
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.
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 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".
In Polish, which does not distinguish long and short vowels, Morse mnemonics are also words or short phrases that begin with each appropriate letter, but dash is coded as a syllable containing an "o" (or "ó"), while a syllable containing another vowel codes for dot. For some letters, multiple mnemonics are in use; the table shows one example.
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 ...
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 ...
