Chart of the Morse code 26 letters and 10 numerals [1]. This Morse key was originally used by Gotthard railway, later by a shortwave radio amateur [2]. Morse code is a telecommunications method which encodes text characters as standardized sequences of two different signal durations, called dots and dashes, or dits and dahs.
The Russian Morse code approximates the Morse code for the Latin alphabet. It was enacted by the Russian government in 1856. [ 1][ 2] To memorize the codes, practitioners use mnemonics known as напевы (loosely translated "melodies" or "chants"). The "melody" corresponding to a character is a sung phrase: syllables containing the vowels а ...
The International Radiotelephony Spelling Alphabet or simply Radiotelephony Spelling Alphabet, commonly known as the NATO phonetic alphabet, is the most widely used set of clear-code words for communicating the letters of the Roman alphabet. Technically a radiotelephonic spelling alphabet, it goes by various names, including NATO spelling ...
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 ...
The Greek Morse code alphabet uses one extra letter for Greek letter Χ and no longer uses the codes for Latin letters "J", "U" and "V". The tonos is not transmitted in Morse code; the receiver can simply infer which vowels require one. The Greek diphthongs presented in the bottom three rows of the table are specified in old Greek Morse-code ...
The procedure signs below are compiled from the official specification for Morse Code, ITU-R M.1677, International Morse Code, [1] while others are defined the International Radio Regulations for Mobile Maritime Service, including ITU-R M.1170, [8] ITU-R M.1172, [4] and the Maritime International Code of Signals, [5] with a few details of their ...

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 ...
