About Morse Code Translator HQ

Morse Code Translator HQ makes free, accurate code and cipher tools for learners, puzzle fans, teachers and radio amateurs.

Tools so far: the Morse code translator with sound, light, vibration and WAV download, and the printable Morse code alphabet.

How we check the code

• Every character comes from the international standard, ITU-R Recommendation M.1677-1, read in the original, and is checked against two other published tables.
• Symbols that aren't in the standard are labeled as unofficial, and we say so where sources disagree.
• Timing follows the ITU spacing rules and the ARRL's published Farnsworth formula. Automated tests check every character and the timing math on each release.
