What is Morse Code?

Morse code is a method of encoding text characters using sequences of dots (·) and dashes (−), known as "dits" and "dahs". Developed in the 1830s by Samuel Morse and Alfred Vail for use with the telegraph, it was the primary method of long-distance communication before the telephone. Today, Morse code is still used in amateur radio, aviation, and emergency signaling.

The International Morse Code standard, also known as Continental Morse Code, was established by the International Telecommunication Union (ITU) and is defined in ITU-R M.1677-1.

Morse Code Timing

The timing of Morse code signals follows a precise standard:

• Dot (dit): 1 time unit
• Dash (dah): 3 time units
• Gap between symbols within a letter: 1 time unit
• Gap between letters: 3 time units
• Gap between words: 7 time units

Speed is typically measured in Words Per Minute (WPM), using the word "PARIS" as a standard reference (50 time units).

Common Uses

• Amateur (Ham) Radio: Operators use Morse code (CW mode) for long-distance communication
• Aviation: Navigational aids like VOR and NDB stations identify themselves using Morse code
• Emergency Signaling: SOS (· · · − − − · · ·) is the international distress signal
• Military Communication: Used when voice communication is not possible or practical
• Accessibility: People with disabilities can communicate using Morse code input devices
• Educational Purpose: Learning Morse code helps understand early telecommunications history

Learning Tips

• Start with common letters like E, T, A, N, I, M, S, O (they use simple patterns)
• Practice listening to Morse code at slow speeds first, then gradually increase
• Learn the rhythm patterns rather than counting dots and dashes
• Use the Farnsworth method: slow character spacing but correct character speed
• Practice daily in short sessions rather than long infrequent ones

Brief History

Morse code was developed in the 1830s and 1840s by Samuel F.B. Morse and his assistant Alfred Vail. The original American Morse code was used on telegraph lines in the United States. Later, a standardized International Morse Code was developed for use on submarine cables and radio. This international version is what we use today.
