Common Mistakes to Avoid
-
Confusing P and R: They’re both dit-dah-dit patterns, but:
- P: dit-DAH-DAH-dit (two dahs in middle)
- R: dit-DAH-dit (one dah in middle)
-
Forgetting the double letters: “Happy” has two Ps, and both words share letters. Make sure each letter is clearly separated.
-
Rushing “Birthday”: It’s a long word with 8 letters. Take your time, especially through the RTHD section which has varied rhythms.
-
Making T sound like a pause: T is just one dah, but it’s a deliberate signal, not silence. Make sure it’s clearly audible.
-
Inconsistent Y: Y appears twice (-·—) and should sound identical both times. Practice it separately.
Frequently Asked Questions
What’s a shorter way to say “Happy Birthday” in Morse code?
If the full phrase is too long, consider:

| HB | ···· -··· | 8 |
