D in Morse code

How to say it

Operators don’t say “dot dash” — they say dah dit dit. Saying the rhythm out loud is the quickest way to make it stick.

Mnemonic

Think: DOG did it. Stressed syllables are dahs, unstressed are dits. Use it to get started, then drop it — at real speed you won’t have time to think.

Timing

2 dits and 1 dah. A dah is three times the length of a dit, with a one-dit gap between each symbol. The whole letter is 7 units long.

Where you learn it

In the Koch order DotDash uses, D is character number 38 of 40. You learn it by sound at full speed, with a new character unlocked each time you reach 90% accuracy.
