  2. 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 ...

  3. 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 ...

  4. Prosigns for Morse code - Wikipedia

    en.wikipedia.org/wiki/Prosigns_for_Morse_code

    Many Morse code prosigns do not have written or printed textual character representations in the original source information, even if they do represent characters in other contexts. For example, when embedded in text the Morse code sequence represents the "double hyphen" character (normally " = ", but also " – – " ). [1]

  5. Q code - Wikipedia

    en.wikipedia.org/wiki/Q_code

    Q code. This is one of a set of articles on telegraphy. The Q-code is a standardised collection of three-letter codes that each start with the letter "Q". It is an operating signal initially developed for commercial radiotelegraph communication and later adopted by other radio services, especially amateur radio.

    Proprietary. macOS. MacLoggerDX is a full-featured amateur radio contact logger for macOS with Transceiver control, Rotor control, Callbook lookup, QSL handling (Hardcopy / LoTW / eQSL / Club Log), DX Cluster and spotting, and basic contesting support. It also works with WSJT-X to control the transceiver while making digital contacts, etc.

  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 ...

  8. Morse code mnemonics - Wikipedia

    en.wikipedia.org/wiki/Morse_code_mnemonics

    Visual mnemonic charts have been devised over the ages. Baden-Powell included one in the Girl Guides handbook in 1918. A contemporary Morse code chart. Here is a more up-to-date version, ca. 1988: Other visual mnemonic systems have been created for Morse code, mapping the elements of the Morse code characters onto pictures for easy memorization.

  9. QSA and QRK radio signal reports - Wikipedia

    en.wikipedia.org/wiki/QSA_and_QRK_radio_signal...

    The QSA code and QRK code are interrelated and complementary signal reporting codes for use in wireless telegraphy ( Morse code ). An enhanced format, SINPO code, was published in the ITU Radio Regulations, Geneva, 1959, [1] but is longer and unwieldy for use in the fast pace of Morse code communications.
