For commercial radiotelegraph licenses in the United States, the Federal Communications Commission specifies tests for Morse code proficiency in words per minute and in code groups per minute. [57]: §13.207(c), §13.209(d) The FCC specifies that a "word" is 5 characters long. The Commission specifies Morse code test elements at 16 code groups ...
In Czech, the mnemonic device to remember letters in Morse code lies in remembering words or short phrases that begin with each appropriate letter and have a long vowel (i.e. á é í ó ú ý) for every dash and a short vowel (a e i o u y) for every dot. Additionally, some other sets of words with a particular theme have been thought up in ...
So the baud rate of a Morse code is 50 ⁄ 60 × word per minute rate. It is standard practice to use two different such standard words to measure Morse code speeds in words per minute. The standard words are: "PARIS" and "CODEX". In Morse code "PARIS" has a dot duration of 50, while "CODEX" has 60.
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.
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 — 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 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 ...
At the beginning of each practice session the QST year and month of publication as well as the page numbers are given followed by the article being transmitted at 5, 7-1/2, 10, 13 and 15 words per minute for "slow code" and 35, 30, 25, 20, 15, 13 and 10 for "fast code". Because these training sessions are scheduled for specific published days ...
