Morse Code Trainer: Learn CW by Ear, Koch Method (Free)

The Koch method (Ludwig Koch, 1930s) with Farnsworth spacing: every letter is sent at full speed from day one, and you add a new one when you copy 90% of what you hear. Character order is the one most online CW courses use. Morse is no longer on any FCC ham exam (dropped in 2007), but it's still on the air every day. Not affiliated with the FCC, ARRL or any CW club.
