Learn Morse code by ear

1. Learn by sound, not by sight. Hear “di-dah” for A rather than picturing a dot and a dash. Use the Listen mode of the quiz.
2. Keep characters fast. Set character speed to around 18–20 WPM from the start, and use Farnsworth spacing (for example 8–10 WPM) to give yourself thinking time.
3. Add characters gradually. This page follows the Koch order: start with K and M, and add new characters when you reach about 90% accuracy.
4. Practise little and often. Ten to fifteen minutes a day beats an hour once a week.
5. Review weak characters. After each round, use “Practise missed characters”.
6. Copy real groups. When you know a dozen characters, try the speed test.

Why the Koch method?

The Koch method, developed by the German psychologist Ludwig Koch in the 1930s, has you listen at full character speed from the very first lesson with only two characters, adding one or two at a time. Because you never slow down, you don't have to unlearn a counting habit later. The character order used here follows the widely used G4FON Koch trainer.
