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 developers ...
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. 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 Russian Morse code approximates the Morse code for the Latin alphabet. It was enacted by the Russian government in 1856. [1][2] To memorize the codes, practitioners use mnemonics known as напевы (loosely translated "melodies" or "chants"). The "melody" corresponding to a character is a sung phrase: syllables containing the vowels а ...
For example, when embedded in text the Morse code sequence represents the "double hyphen" character (normally "=", but also "– –"). [1] When the same code appears alone it indicates the action of spacing down two lines on a page in order to create the white space indicating the start of a new paragraph [ 2 ] or new section in a message ...
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 ...
t. e. A continuous wave or continuous waveform (CW) is an electromagnetic wave of constant amplitude and frequency, typically a sine wave, that for mathematical analysis is considered to be of infinite duration. [1] It may refer to e.g. a laser or particle accelerator having a continuous output, as opposed to a pulsed output.
Baudot developed his first multiplexed telegraph in 1872 [2] [3] and patented it in 1874. [3] [4] In 1876, he changed from a six-bit code to a five-bit code, [3] as suggested by Carl Friedrich Gauss and Wilhelm Weber in 1834, [2] [5] with equal on and off intervals, which allowed for transmission of the Roman alphabet, and included punctuation and control signals.
