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. [ 3 ][ 4 ] Morse code is named after Samuel Morse, one of the early ...
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.
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 ...
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 ...
Friedrich Clemens Gerke, 1840. Friedrich Clemens Gerke (22 January 1801 – 21 May 1888) was a German writer, journalist, musician and pioneer of telegraphy who revised the Morse code in 1848. It is Gerke's version of the original (American) Morse code now known as the International Morse code and standardized by the ITU (International ...
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 companies that ...
An emoticon (/ əˈmoʊtəkɒn /, ə-MOH-tə-kon, rarely / ɪˈmɒtɪkɒn /, ih-MOTT-ih-kon), [1][2][3][4] short for emotion icon, [5] is a pictorial representation of a facial expression using characters —usually punctuation marks, numbers and letters —to express a person's feelings, mood or reaction, without needing to describe it in detail.
telegraph key, recording telegraph, ‘dot-and-dash’ telegraph alphabet. Alfred Lewis Vail (September 25, 1807 – January 18, 1859) was an American machinist and inventor. Along with Samuel Morse, Vail was central in developing and commercializing American electrical telegraphy between 1837 and 1844. [1][a] Vail and Morse were the first two ...
