  2. Prosigns for Morse code - Wikipedia

    en.wikipedia.org/wiki/Prosigns_for_Morse_code

    Diagram of a telegraph key used to send messages in 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 ...

  3. 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 ...

    The American Radio Relay League ( ARRL) is the largest membership association of amateur radio enthusiasts in the United States. ARRL is a non-profit organization, and was co-founded on April 6, 1914, by Hiram Percy Maxim and Clarence D. Tuska of Hartford, Connecticut. The ARRL represents the interests of amateur radio operators before federal ...

  5. R-S-T system - Wikipedia

    en.wikipedia.org/wiki/R-S-T_system

    The R-S-T system is used by amateur radio operators, shortwave listeners, and other radio hobbyists to exchange information about the quality of a radio signal being received. The code is a three digit number, with one digit each for conveying an assessment of the signal's readability, strength, and tone. [1] [2] The code was developed in 1934 ...

  6. W1AW - Wikipedia

    en.wikipedia.org/wiki/W1AW

    W1AW is the flagship station for amateur radio operation within the United States. Using pre-established shortwave frequencies and Maxim's distinctive call sign (W1AW), this station transmits one-way voice and digital bulletins in addition to morse code training practice. The transmissions are broadcast Monday through Friday with the first ...

  7. 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 ...

  8. List of amateur radio modes - Wikipedia

    en.wikipedia.org/wiki/List_of_amateur_radio_modes

    Morse code is called the original digital mode. Radio telegraphy, designed for machine-to-machine communication is the direct on / off keying of a continuous wave carrier by Morse code symbols, often called amplitude-shift keying or ASK, may be considered to be an amplitude modulated mode of communications, and is rightfully considered the ...

  9. QN Signals - Wikipedia

    en.wikipedia.org/wiki/QN_Signals

    The QN Signals are Morse code operating signals that were introduced for Amateur radio net operation in 1939 on the Michigan QMN Net to lighten the burdens of net control operators. Originally created by a committee of the Detroit Amateur Radio Association led by Ralph Thetreat, W8FX. [1] Ev Battey W1UE (W4IA-SK), then ARRL assistant ...
