THE DITDAY LEARNING GUIDE
Learn Morse code, one sound at a time.
Morse code turns letters, numbers, and punctuation into short and long sounds. You can start learning by ear with just two characters. No account, equipment, or previous radio experience is needed.
Start with the rhythm
A short sound is a dit; a long sound is a dah. A dah lasts three times as long as a dit. The silence between sounds is part of the code too. Instead of counting marks on a chart, listen for the complete rhythm of a character and connect that sound to its letter.
Try these first two sounds. K has a long–short–long rhythm. M has two long sounds. After comparing them, look away from the labels and try a lesson.
A Morse alphabet reference is useful when you want to check a symbol. It is less useful as something to stare at while trying to recognize every sound. In ditday, the visual cue starts hidden and can be revealed when you need support.
Build a small, reliable vocabulary
Learn mode introduces a small set of sounds and mixes them in short exercises. The first sessions contain six questions using K and M. Later lessons contain twelve questions. Correct answers advance automatically; mistakes stay on screen so you can compare the answer before continuing.
Two consecutive lessons at 90% accuracy or better, without opening letter-labelled hints, qualify you to introduce the next sound once the newest character has at least three correct recalls. Introducing a character is a milestone, not proof that you can recognize it reliably in every setting.
This gradual introduction follows the idea behind the Koch method. The app brings earlier sounds back alongside the newest one, giving more attention to weak and due sounds instead of simply moving through an alphabetical list.
Keep the sounds brisk and the gaps generous
Ditday starts with 20 words-per-minute character timing and wider spacing at an effective 8 words per minute. Individual letters retain their compact rhythm while the gaps give you time to recall them. This is Farnsworth timing. Sound settings let you adjust the pace and pitch.
As more characters are introduced, the app gradually raises the spacing speed. If recall becomes inconsistent, keep practicing at a comfortable setting. Accuracy and consistent recognition are more useful signals than rushing to a larger speed number.
Make a short daily routine
- Complete a Learn lesson with the visual hidden when practical.
- Review sounds you missed in Weak sounds practice.
- Try familiar words when you are ready, then optional full-alphabet messages.
- Come back on another day so you test recall after a real gap.
There is no single completion time that fits everyone. Practice quality, familiarity, hearing conditions, and your target speed all matter. Use accuracy across several days, not just one strong session, to decide when to stretch.
