The one rule: learn by ear
Morse code is a sound language. If you learn it as a picture (“A is dot-dash”), you’ll copy it by counting: hear dit, hear dah, look up the picture. That works up to about 5 words per minute and then becomes a wall. Learn each character as a sound instead – “di-dah” is A – and recognition becomes instant.
The Koch method
Developed by the German psychologist Ludwig Koch in the 1930s:
- Start with two characters at your target speed (around 15–20 words per minute).
- Copy random groups of them until you get 90% right.
- Add one new character. Repeat.
Because the speed never changes, you never have to unlearn a slow habit. The cost is that the first sessions feel hard – that’s normal.
Farnsworth spacing
Farnsworth timing sends each character at full speed but stretches the gaps between characters. You hear the right sound, and still have time to think. As you improve, the gaps shrink until they match the character speed. Our game sends characters at the speed you set with gaps equal to about 12 words per minute.
A 10-minute daily plan
| Minutes | What to do |
|---|---|
| 0–6 | Koch practice with the characters you have so far |
| 6–8 | Listen to a few words in the translator without looking |
| 8–10 | Send to yourself: tap out a short word on the table, saying the sounds |
Short and daily matters more than long. Your brain consolidates the sounds between sessions.
Common mistakes
- Using the chart as a crutch. Look up a character after you miss it, not before.
- Going too slow. Below about 12–15 WPM characters become separate dots and dashes again.
- Writing down dots and dashes. Write only the letter you heard – or nothing.
