About Morse Code
Morse code is a method of encoding text characters as sequences of dots (·) and dashes (—). Developed by Samuel Morse and Alfred Vail in the 1830s, it was originally used for electric telegraph communication. Today, Morse code is still used in amateur radio, aviation, navigation beacons, and by the military.
Timing Rules
- Dot: 1 unit of time
- Dash: 3 units of time
- Space between parts of same letter: 1 unit
- Space between letters: 3 units
- Space between words: 7 units
Frequently Asked Questions
What is Morse code?
Morse code is a method of telecommunication that encodes text characters as standardized sequences of two different signal durations — dots (short) and dashes (long).
Who invented Morse code?
Morse code was developed by Samuel Morse and Alfred Vial in the 1830s-1840s for use with the electric telegraph.
How do dots and dashes work?
A dot is a short signal, a dash is a long signal (typically 3x the length of a dot). Letters are separated by the length of one dash, words by seven dots.
Is Morse code still used?
Yes, Morse code is still used in aviation, amateur radio, navigation, and by the military. It also remains popular as a hobby among amateur radio operators.
