Tap to spell

NATO is the ICAO radiotelephony alphabet. The official spellings are “Alfa” and “Juliett”; the common variants are accepted when reading.
DIN 5009 is the 2022 German standard built from city names. German (1996) is the older given-name alphabet still in everyday use.
Each cell also shows the letter's Morse code, its flag-semaphore arm positions as seen by the receiver, and its maritime signal flag.
Auto switches to reading when every word in the input is a recognised call. A “/” between calls marks a word break.
