Morse code speed is measured in words per minute (WPM) or characters per minute (CPM). ... A "poor fist" is a characteristic of sloppy or hard to copy Morse code.
In amateur radio, high-speed telegraphy (HST) is a form of radiosport that challenges amateur radio operators to accurately receive and copy, and in some competitions to send, Morse code transmissions sent at very high speeds. This event is most popular in Eastern Europe.
Experienced hams routinely send Morse at 20 words per minute, using manually operated hand telegraph keys; enthusiasts such as members of The CW Operators' Club routinely send and receive Morse code at speeds up to 60 wpm. The upper limit for Morse operators attempting to write down Morse code received by ear using paper and pencil is roughly ...
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.
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 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 ...
The dotting rate of Morse code is the reciprocal of the dot duration, e.g. at twenty words per minute based upon the standard word PARIS with a dot duration of 50 milliseconds, the dotting rate is 20 times per second (20 = 1.0 / 0.050). The dotting rate is even faster for higher speed Morse code.
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 ...
