  2. Morse code - Wikipedia

    en.wikipedia.org/wiki/Morse_code

    Morse code is a method used in telecommunication to encode 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 . International Morse code encodes the 26 ...

    Historical Morse code prosigns Prosign Matching voice procedure word Former code symbol Explanation Reference CQD: Distress call Obsolete code used to call all stations during distress (see CQ). Replaced by SOS in 1906 (see above). VE: General call Code re-used for "Message verified" or "Message understood" (see SN above). Replaced by CQ (see ...

  4. Morse code abbreviations - Wikipedia

    en.wikipedia.org/wiki/Morse_code_abbreviations

    An amateur radio Morse code conversation example. To make Morse code communications faster and more efficient, there are many internationally agreed patterns or conventions of communication which include: extensive use of abbreviations, use of brevity codes such as 92 Code, RST code, Q code, Z code as well as the use of Morse prosigns. The ...

  5. Talk:Morse code abbreviations - Wikipedia

    en.wikipedia.org/wiki/Talk:Morse_code_abbreviations

    The lede currently contains the following: 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 ...

  6. Morse code mnemonics - Wikipedia

    en.wikipedia.org/wiki/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. Amateur radio clubs can provide resources to ...

  7. Amateur radio - Wikipedia

    en.wikipedia.org/wiki/Amateur_radio

    Radiotelegraphy using Morse code, also known as "CW" from "continuous wave", is the wireless extension of landline (wired) telegraphy developed by Samuel Morse and dates to the earliest days of radio.

  8. Telegraph key - Wikipedia

    en.wikipedia.org/wiki/Telegraph_key

    A telegraph key or Morse key is a specialized electrical switch used by a trained operator to transmit text messages in Morse code in a telegraphy system. Keys are used in all forms of electrical telegraph systems, including landline (also called wire) telegraphy and radio (also called wireless) telegraphy. An operator uses the telegraph key to ...

  9. American Morse code - Wikipedia

    en.wikipedia.org/wiki/American_Morse_code

    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 ...
