Interactive Morse Code Trainer
Five complete training modules: Character Quiz, Word List, QSO Simulator, Headline Copy, and Koch Method Course. All with audio playback, scoring, and adaptive difficulty. Free, no account required.
Quick Answer: How the Trainer Works
Our morse code trainer features five interactive modules covering every stage of CW learning. The Character Quiz builds instant audio recognition through multiple-choice drills. The Word List Trainer plays the 100 most common English words for transcription practice. The QSO Simulator recreates real amateur radio exchanges with comprehension questions. The Headline Trainer develops stamina with progressively longer text passages. The Koch Method Course follows the scientifically-proven mastery protocol, adding characters only when you achieve 90% accuracy. All modules include adjustable speed (5-40 WPM), tone frequency, Farnsworth spacing, and score tracking that saves to your browser.
Choose Your Training Module
Pick the module that matches your current skill level. Copy a practice link to share speed, Koch lesson, or QSO seed — local only, not a live room.
Character Quiz
Hear a letter or number. Pick the correct answer from four choices.
Training Tips That Hold Up
Memorizing a silent alphabet chart trains your eyes, not your ears. Switch to the Koch module and copy sound shapes at full character speed. Add a letter only when accuracy stays high.
The QSO simulator is for rhythm: RST, placeholders such as MORSECODER / STATION B, and QTH. It is not a substitute for a first on-air contact with a licensed operator.
Whole-word recognition of short English words (THE, AND, FOR) is faster than spelling every letter once those patterns are automatic. Use the Word List trainer for that drill.
