DotDash: Learn Morse Code

MASTER MORSE CODE BY EAR

DotDash teaches you to hear Morse the way operators do: sounds first, never a lookup table. One guided session a day, five minutes, and the letters start to feel like words.

WHY DOTDASH?

• Audio-first — every character is learned by ear at full 20 WPM character speed; the dot-dash pattern is only ever shown as feedback
• Koch method, done properly — start with E and T, add one character at a time, never move on below 90% accuracy
• Farnsworth spacing that tightens as you improve — from 8 to 15 WPM effective, automatically
• Spaced repetition — weak letters come back at the right moment, mastered ones fade out
• Unit checkpoints — copy real 5-character code groups, the same test amateur radio classes use
• Beep, your signal-lamp coach, listens and reacts as you learn

ONE DAILY SESSION

Warm-up reviews → one new character → mixed recognition, recall and sending drills → words you can already spell. Beginners hear their first letters in under a minute.

PRACTICE YOUR WAY

• Recall drill — hear a letter, tap it from everything you have learned
• Sending drill — key the rhythm on a straight-key pad with instant grading
• Word copy — real words, Q-codes and ham abbreviations built only from your letters
• Daily mystery word — a word puzzle that gets slower with each try; share your solve speed
• Decoder and reference library — look up or hear any character, prosign or Q-code

STAY ON TRACK

• Learning path with unit checkpoints and progress for every character
• Daily streak and XP
