  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 ...

    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 ...

  8. On–off keying - Wikipedia

    en.wikipedia.org/wiki/On–off_keying

    On–off keying is most commonly used to transmit Morse code over radio frequencies (referred to as CW ( continuous wave) operation), although in principle any digital encoding scheme may be used. OOK has been used in the ISM bands to transfer data between computers, for example. OOK is more spectrally efficient than frequency-shift keying, but ...

  9. Template:Morse/doc - Wikipedia

    en.wikipedia.org/wiki/Template:Morse/doc

    The purpose of this template is to produce a rendering of Morse code characters. It is capable of rendering the different timings of American Morse code as well as the standard International Morse code. The template can produce any character or prosign with up to ten symbols (including the word boundary symbol).
