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.
That same Morse code sequence represents the letter U in the Latin alphabet. Hence the SATTS equivalent for ţā' is U. In the Morse-code era, when Arabic language Morse signals were copied down by non-Arab code clerks, the text came out in SATTS. Text in SATTS was also automatically produced when teleprinters reproduced Arabic text, if the ...
The Allied military phonetic spelling alphabets prescribed the words that are used to represent each letter of the alphabet, when spelling other words out loud, letter-by-letter, and how the spelling words should be pronounced for use by the Allies of World War II. They are not a "phonetic alphabet" in the sense in which that term is used in ...
Signal lamp training during World War II. A signal lamp (sometimes called an Aldis lamp or a Morse lamp [1]) is a visual signaling device for optical communication by flashes of a lamp, typically using Morse code. The idea of flashing dots and dashes from a lantern was first put into practice by Captain Philip Howard Colomb, of the Royal Navy ...
The Greek B though, is identical to the English B as far as the glyph is concerned, even though the sound of Greek B is the same as the sound of English V (like the v in word victory). The B prevails to V. The Greek Morse code alphabet uses one extra letter for Greek letter Χ and no longer uses the codes for Latin letters "J", "U" and "V".
Visual mnemonic charts have been devised over the ages. Baden-Powell included one in the Girl Guides handbook [1] in 1918. A contemporary Morse code chart. Here is a more up-to-date version, ca. 1988: Other visual mnemonic systems have been created for Morse code, mapping the elements of the Morse code characters onto pictures for easy ...
A telegraph code is one of the character encodings used to transmit information by telegraphy. Morse code is the best-known such code. Telegraphy usually refers to the electrical telegraph, but telegraph systems using the optical telegraph were in use before that. A code consists of a number of code points, each corresponding to a letter of the ...
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 ...
