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.
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.
Morse code abbreviations are not the same as prosigns.Morse abbreviations are composed of (normal) textual alpha-numeric character symbols with normal Morse code inter-character spacing; the character symbols in abbreviations, unlike the delineated character groups representing Morse code prosigns, are not "run together" or concatenated in the way most prosigns are formed.
The Greek Morse code alphabet is very "similar" to the Latin alphabet. The "similarity" is based first on optical resemblance of each letter, a.k.a. glyph, and then secondly on sound. Example: A both in Greek and English is the same glyph and sound (like a in word apple).
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 ...
A telegraph code is one of the character encodings used to transmit information by telegraphy. Morse code is the best-known such code.Telegraphy usually refers to the electrical telegraph, but telegraph systems using the optical telegraph were in use before that.

Words per minute, commonly abbreviated as WPM (sometimes lowercased as wpm), is a measure of words processed in a minute, often used as a measurement of the speed of typing, reading or Morse code sending and receiving.
