How it is calculated
Patterns come from Recommendation ITU-R M.1677-1 for Latin letters, digits and signs, and from the Arabic Morse table for Arabic. Length in units: dot 1, dash 3, gap inside a letter 1.
Example
Inputs: Group = English letters. Result: Chart as text: A .- B -... C -.-. D -.. E . F ..-. G --. H .... I .. J .--- K -.- L .-.. M -- N -. O --- P .--. Q --.- R .-. S ... T - U ..- V ...- W .-- X -..- Y -.-- Z --..; Symbols: 26.
Limits and caveats
- The signs !, &, ; and $ are common among amateurs but are not in the ITU table, so they are left out.
- Hamza seats, taa marbuta and alif maqsura have no separate patterns in the Arabic table.
Questions about this tool
What is the shortest letter in Morse code?
E, a single dot, followed by T, a single dash, because they are among the most frequent letters in English.
Why do all digits have five elements?
Digits were given a fixed length so they stand apart from letters: 1 is a dot and four dashes, 0 is five dashes.
What does length in units mean?
It is the pattern length when a dot is 1 unit, a dash 3 and each gap inside the letter 1, so A lasts 5 units.
