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 following telegraph code table is adapted from one given by Ashok Kelkar, [2] where the Latin letters are encoded as per the International Morse code standard. Some variations on this code exist, [3] and there have been some attempts to introduce other telegraph codes either to improve efficiency or to apply to more Indian languages.
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.
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 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.

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.
Sometimes the routine transmission is interrupted and brief messages are sent in fast Morse code or in an FSK digital mode. Therefore, a more appropriate term for these beacon-like single-letter transmissions is "channel markers", [ 4 ] [ 12 ] as their purpose is to occupy and identify a particular HF transmission channel when no traffic is ...
