Frequently Asked Questions

Morse code is a character encoding method that uses sequences of dots (·) and dashes (–) to represent letters, numbers, and punctuation. Developed by Samuel Morse in the 1830s for the telegraph, it remained the standard for radio communication for over a century. SOS (··· – – – ···) is the most internationally recognized distress signal.
Words Per Minute (WPM) is the standard speed measure. At 20 WPM a dot lasts 60ms, a dash 180ms, and the gap between letters is 180ms. The standard test word is "PARIS" (. .–. .–. .. ...–), which contains exactly 50 timing units. A licensed amateur radio operator is typically tested at 5–20 WPM.
Use · or . for dot, – or - for dash, a single space between letters, and / or double space between words. For example: "SOS" = "... --- ..." and "HELLO WORLD" = ".... . .-.. .-.. --- / .-- --- .-. .-.. -..".
