FAQ

How do you read Morse code?
Each letter is a combination of dots (.) and dashes (−). For example, SOS: "... --- ..." (3 dots, 3 dashes, 3 dots). Letters are separated by spaces; words by " / ". A dot is 1 unit long; a dash is 3 units.
What does WPM mean?
WPM = Words Per Minute. The standard reference word is "PARIS" (50 units). At 20 WPM, one unit is about 60 ms. Beginners typically practice at 5–10 WPM; experienced operators use 20–25 WPM.
Is Morse code still used today?
Yes. It remains in use in maritime and aviation as an emergency signal, in amateur radio (ham radio), and in some military applications. The international distress signal SOS (... --- ...) is universally recognised.

What is Morse Code?

Morse code is an encoding system that represents letters and numbers as combinations of short (dot) and long (dash) signals. Developed in the 1840s by Samuel Morse and Alfred Vail, it formed the foundation of telegraph communication.

International Morse Code (ITU)

The current standard is International Morse Code as defined by the ITU. It covers all Latin letters A–Z, digits 0–9, and common punctuation marks.

Timing Rules

  • Dot (·): 1 unit
  • Dash (−): 3 units
  • Gap between symbols: 1 unit
  • Gap between letters: 3 units
  • Gap between words: 7 units

SOS — The Universal Distress Signal

SOS (... --- ...) has been the international distress call since 1908. It is not an abbreviation but a symbol sequence chosen for its simplicity and distinctiveness. It remains valid in maritime and aviation today.
