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.
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.
A reduction of the number of telegraphy examination element levels from three to one. Both the Amateur Extra Class' 20 words-per-minute (WPM); and General and Advanced classes' 13 WPM Morse code tests, were removed in favor of a standardized 5 WPM as the sole Morse code requirement for both the General and Extra Class licenses.
The procedural signal " SK" (or "VA") has historically been used in Morse code as the last signal sent from a station before ending operation, [35] usually just before shutting off the transmitter. Since this was the last signal received by other operators, the code was adopted to refer to any amateur radio operator who is deceased, regardless ...
In 1865, a conference in Paris adopted the Gerke code as the international standard, calling it International Morse Code. With some very minor changes, this is the Morse code used today. The Cooke and Wheatstone telegraph needle instruments were capable of using Morse code since dots and dashes could be sent as left and right movements of the ...

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.
