Seen as timing

A dot is one unit, a dash three, and the gap between them one. At 20 words per minute a unit is 60 milliseconds.

Words chosen so a letter survives a bad radio link. Alfa and Juliett are spelled oddly on purpose — some languages would swallow the ph and the final t.

How to read this

  • In Morse a dot is one unit and a dash three. The commoner the letter, the shorter the code — E is a single dot.
  • Each NATO word starts with its own letter. It is for saying a letter clearly over the radio.
  • A braille cell has six dot positions, so there are sixty-four of them. The empty one is the space between words.
  • Digits in braille reuse the cells of a–j; a number sign in front tells them apart.
