Morse code. 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 of the system adopted for electrical telegraphy .
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 ...
Morse code abbreviations are used to speed up Morse communications by foreshortening textual words and phrases. Morse abbreviations are short forms, representing normal textual words and phrases formed from some (fewer) characters taken from the word or phrase being abbreviated. Many are typical English abbreviations, or short acronyms for ...
The Novice Class operator license was for persons who had passed a 5 word per minute (wpm) Morse code examination and a basic theory exam. [6] After the 1987 restructuring, privileges included four bands in the HF range (3–30 MHz), one band in the VHF range (30–300 MHz), and one band in the UHF range (300–3,000 MHz).
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 ...
In that word, tall letters (those descending below the baseline or ascending above the mean line – b, d, f, g, h, j, k, l, p, q, t, or y) and capital letters represent dashes, while short letters (aceimnorsuvwxz) represent dots. To recall the Morse code for a character, try to visualize the word.
Gersh Budker (1918–1977), Russia – electron cooling, co-inventor of collider. Edward Bull (1759–1798), England – Bull engine (a modified steam engine) Robert Bunsen (1811–1899), Germany – Bunsen burner. Henry Burden (1791–1871), Scotland and U.S. – Horseshoe machine, first usable iron railroad spike.
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". The tonos is not transmitted in Morse code; the receiver can simply infer which vowels require one. The Greek diphthongs presented in the bottom three rows of the table are specified in old Greek Morse-code ...
