How to read Morse code
Each letter is a sequence of dots (short signal) and dashes (long signal, three times a dot). The spacing rules are part of the code itself: within a letter the symbols are one dot-length of silence apart, between letters three, between words seven — which is why written Morse uses a space between letters and a slash "/" between words. The "Play" button reproduces exactly these timings with your browser's audio, handy for training your ear the way telegraph operators once did.
SOS and the most famous sequences
The SOS distress signal (... --- ...) was chosen in 1906 precisely because it
is unmistakable even through a noisy transmission: it doesn't stand for anything, it's simply
easy to recognize. Morse is still alive among amateur radio operators and in aviation, where
radio beacons still identify themselves in Morse. The chart above covers letters, numbers and
common punctuation, including the @ sign — the newest addition, made official in 2004 for
spelling out email addresses over the air.
