THE DITDAY LEARNING GUIDE
The Morse code alphabet, with sound.
Use this reference to hear and compare International Morse code characters. A dot is a short dit; a dash is a dah lasting three dits. Select Hear beside a character to play its rhythm.
Examples use 20 WPM character timing. Sound starts only when you choose an example. Keep the volume comfortable, and stop playback when you need a break.

How to read the marks
The table shows the elements within each character. They are separated by one dit of silence. With standard timing, characters are separated by three dit units and words by seven. Wider Farnsworth spacing leaves extra time between characters and words while preserving each character’s rhythm.
A slash in written Morse examples often marks a word boundary. The slash character itself has its own signal, shown in the punctuation table. An equals sign shares the pattern often used for a break signal in radio practice; a punctuation character and an operating procedure are not always interchangeable.
Turn the reference into listening practice
A chart is useful for checking an unfamiliar character, but reading dots and dashes is a different task from recognizing Morse by ear. Listen to a small number of examples, then look away and test your recall. Try K and M first if the alphabet is new to you.
Ditday’s current Learn sequence introduces 40 sounds; this reference also includes zero, which is supported by the audio engine but is not currently in that sequence. The punctuation section covers the symbols supported by the app, not every International Morse operating signal or prosign.
When you are ready, follow the beginner’s guide or start a short lesson. Word and message practice helps you move beyond isolated characters.
