K in Morse code
-.- · dah dit dah
How to say it
Operators don’t say “dot dash” — they say dah dit dah. Saying the rhythm out loud is the quickest way to make it stick.
Mnemonic
Think: KAN-ga-ROO. 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.
K is the first letter taught in the Koch method and is also the prosign for “over”.
Timing
1 dit and 2 dahs. A dah is three times the length of a dit, with a one-dit gap between each symbol. The whole letter is 9 units long.
Where you learn it
In the Koch order DotDash uses, K is character number 1 of 40. You learn it by sound at full speed, with a new character unlocked each time you reach 90% accuracy.
