Morse code trainer
Hear any text as Morse code, then practice copying with Koch method drills. No Morse exam is required for any US license, but CW is still widely used.
Speed and tone
Learning at a fast character speed with extra space between characters (Farnsworth spacing) helps you hear each character as a sound rather than counting dots and dashes.

Koch practice
Start with two characters. Copy five groups of five, and add a character once you reach 90 percent.
How it works
- A dash is three dots, the space between characters is three dots and the space between words is seven dots (ITU-R M.1677-1). Speed uses the 50-unit "PARIS" word, so one dot lasts 1200 / wpm milliseconds.
- With Farnsworth spacing, characters keep their full speed and extra time is added between characters and words, using the formula in Bloom, "A Standard for Morse Timing Using the Farnsworth Technique" (QEX, April 1990).
