  2. Morse code - Wikipedia

    en.wikipedia.org/wiki/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.

  3. Morse code mnemonics - Wikipedia

    en.wikipedia.org/wiki/Morse_code_mnemonics

    Slavic languages In Czech, the mnemonic device to remember letters in Morse code lies in remembering words or short phrases that begin with each appropriate letter and have a long vowel (i.e. á é í ó ú ý) for every dash and a short vowel (a e i o u y) for every dot. Additionally, some other sets of words with a particular theme have been thought up in Czech folklore, such as the ...

  4. SOS - Wikipedia

    en.wikipedia.org/wiki/SOS

    In International Morse Code three dots form the letter "S" and three dashes make the letter "O", so "S O S" became a common way to remember the order of the dots and dashes. IWB, VZE, 3B, and V7 form equivalent sequences, but traditionally SOS is the easiest to remember.

  5. American Morse code - Wikipedia

    en.wikipedia.org/wiki/American_Morse_code

    As already mentioned, American Morse is less suitable for use on cables because of the high density of dots. However, this same feature, together with the shorter dash, leads to the advantage of a more compressed code and a faster sending rate. The same operator could send at least 20% faster with American Morse than with International Morse. [6] The greater complexity of American Morse meant ...

  6. Prosigns for Morse code - Wikipedia

    en.wikipedia.org/wiki/Prosigns_for_Morse_code

    Prosigns for Morse code. Procedural signs or prosigns are shorthand signals used in Morse code telegraphy, for the purpose of simplifying and standardizing procedural protocols for landline and radio communication. The procedural signs are distinct from conventional Morse code abbreviations, which consist mainly of brevity codes that convey ...

  7. Morse code abbreviations - Wikipedia

    en.wikipedia.org/wiki/Morse_code_abbreviations

    Morse code abbreviations are not the same as prosigns.Morse abbreviations are composed of (normal) textual alpha-numeric character symbols with normal Morse code inter-character spacing; the character symbols in abbreviations, unlike the delineated character groups representing Morse code prosigns, are not "run together" or concatenated in the way most prosigns are formed.

  8. CQD - Wikipedia

    en.wikipedia.org/wiki/CQD

    At the first International Radiotelegraphic Convention, held in Berlin in 1906, Germany's Notzeichen distress signal of three-dots three-dashes three-dots ( ) was adopted as the international Morse code distress signal. [5] This distress signal soon became known as "SOS" because it has the same dash-dot sequence as the letters S O S with the gaps between the letters removed, and in fact is ...

  9. Telegraph code - Wikipedia

    en.wikipedia.org/wiki/Telegraph_code

    For instance, American Morse code had about five elements, rather than the two (dot and dash) of International Morse Code. Codes meant for human interpretation were designed so that the characters that occurred most often had the fewest elements in the corresponding code point.
