About Morse Code
What is Morse code? ▼
Morse code is a character encoding system representing text using sequences of dots (·) and dashes (—). It was invented by Samuel Morse and Alfred Vail in the 1830s for electrical telegraph communication. Each letter and digit has a unique combination of dots and dashes.
How do I read Morse code? ▼
A dot (.) is a short signal, a dash (-) is a long signal (3x dot duration). Letters are separated by spaces. Words are separated by a slash (/) or longer pause. SOS for example is: · · · — — — · · · (three dots, three dashes, three dots).
Is Morse code still used today? ▼
Yes! Morse code is still used in amateur (ham) radio, aviation navigation beacons, and military communication. Some people use it for accessibility purposes. The SOS distress signal (· · · — — — · · ·) is internationally recognized.
