Koch Method CW Audio Course
The Koch method, the way Ludwig Koch designed it for learning Morse by ear, as downloadable audio you can practise with anywhere. Characters at full speed so you learn the rhythm, spaced out so you never learn to count dots. One new character per lesson, with answer keys to track your progress.
Instant download — all sales are final, no refunds. Try the free browser trainer first to see if the Koch method suits you.
What you get
- 39 graded lessons. One per new Koch character, 40 characters in all. Lesson 1 starts with two letters; each lesson adds one.
- Full-speed characters. Sent at 20 WPM character speed with Farnsworth spacing (10 WPM overall) — you learn the sound, never counting dots.
- Answer keys. Every lesson ships the exact 5-character groups so you can score your copy.
- Offline & portable. Plain audio files — phone, car, gym, headphones, no internet, no screen.
Why audio (and why it's not the free trainer)
The Koch trainer on this site is free and great at a desk. This course is the opposite situation: structured, offline, screen-free practice you can do on a commute, a walk, or at the gym. The hard part of learning CW is the daily reps — the course makes those reps portable, sequenced, and self-scoring. That convenience is what you're paying for; the web tools stay free forever.
How it works
- Download, start at Lesson 1 (two characters), pencil and paper ready.
- Write what you hear in 5-character groups.
- Score against the answer key. At ~90% accuracy, move to the next lesson.
- Practise every day. How fast you progress depends mostly on how regularly you practise.
