    en.wikipedia.org/wiki/Clansman_(military_radio)

    The ATU can also match any other wire antenna to the operating frequency. The set together with its ancillaries (batteries, cables, audio gear and antenna parts) together make up the complete equipment schedule (CES). The use of morse code and later data transmission and reception could extend the range and add to the versatility of the UK/PRC ...

    en.wikipedia.org/wiki/Spark-gap_transmitter

    The spark gap is inside the box with the transparent cover at top center. A spark-gap transmitter is an obsolete type of radio transmitter which generates radio waves by means of an electric spark. [1] [2] Spark-gap transmitters were the first type of radio transmitter, and were the main type used during the wireless telegraphy or "spark" era ...

  4. Linear timecode - Wikipedia

    en.wikipedia.org/wiki/Linear_timecode

    Linear (or Longitudinal) Timecode ( LTC) is an encoding of SMPTE timecode data in an audio signal, as defined in SMPTE 12M specification. The audio signal is commonly recorded on a VTR track or other storage media. The bits are encoded using the biphase mark code (also known as FM ): a 0 bit has a single transition at the start of the bit period.

    The procedure signs below are compiled from the official specification for Morse Code, ITU-R M.1677, International Morse Code, while others are defined the International Radio Regulations for Mobile Maritime Service, including ITU-R M.1170, ITU-R M.1172, and the Maritime International Code of Signals, with a few details of their usage appearing ...

  6. 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 ...

  7. 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 ...
