What's the difference between flashcards and the Koch trainer?

The Koch trainer at /practice/ teaches you to copy Morse by ear — it plays the tone, you type the letter. Flashcards work visually: you see the dits and dashes (or the letter) on screen and type the answer. Use flashcards before headphones come on; use the Koch trainer once you're comfortable reading patterns.

Which mode should I start with?

Start with 'See Morse → letter' on the alphabet set. Once you can clear 90% accuracy on letters, add numbers and try 'See letter → type Morse' to lock in the patterns from both directions.

Morse Code Flashcards – Visual Recognition & Reverse Drill

Week 1. Letters only, "See Morse → type the letter" mode. Aim for 5 minutes a day until you can clear the alphabet at > 80% accuracy.
Week 2. Add numbers. Same mode. The number patterns are systematic (1 = .---- through 9 = ----.) — they come fast once you spot the pattern.
Week 3. Switch to "See letter → type the Morse". This is where memorisation becomes recall. Most learners' accuracy drops temporarily — that's normal.
Week 4. Move to the Koch audio trainer. The flashcard work has built the pattern library; audio adds the rhythm.

Use the printable chart as a reference while drilling. When you mistake a letter twice in one session, go look it up on the chart before the next attempt — short feedback loops beat brute-force repetition every time.
