    en.wikipedia.org/wiki/Morse_code_mnemonics

    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 ...

    The Commission specifies Morse code test elements at 16 code groups per minute, 20 words per minute, 20 code groups per minute, and 25 words per minute. [57]: §13.203(b) The word per minute rate would be close to the PARIS standard, and the code groups per minute would be close to the CODEX standard.

    en.wikipedia.org/wiki/QSK_operation_(full_break-in)

    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.
