  3. Morse code mnemonics - Wikipedia

    en.wikipedia.org/wiki/Morse_code_mnemonics

    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 ...

  9. Morse code for non-Latin alphabets - Wikipedia

    en.wikipedia.org/wiki/Morse_code_for_non-Latin...

    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".
