K in Morse Code
The letter K in Morse code is -.- (dah dit dah): 1 dot and 2 dashes. Listen to it, learn how to write it, and see the letters it is easily confused with.
Step by step
How to write K in Morse code
Send the 3 signals in order, from left to right. Keep the pauses inside the letter short (one unit) so the receiver hears a single character.
- Dash (dah)
One long signal, three units of time. Then a one-unit pause before the next signal.
- Dot (dit)
One short signal, one unit of time. Then a one-unit pause before the next signal.
- Dash (dah)
One long signal, three units of time. Then a three-unit pause before the next letter.
How to say it: "dah dit dah"
Operators never say "dot" and "dash" out loud: they say dit for a dot and dah for a dash, because those syllables have the same short and long rhythm as the signals themselves. Spoken aloud, K is "dah dit dah". Saying it this way while you listen is the quickest way to make the pattern automatic.
Timing of the letter K
Proportional view: teal blocks are sound (dot = 1 unit, dash = 3 units), gaps are silence. The whole letter takes 9 units; at 15 WPM that is about 0.72 seconds.

About the letter K in Morse code
K is the 11th letter of the alphabet and a consonant. In International Morse code it is written -.-, a sequence of 3 signals: 1 dot and 2 dashes. Spoken aloud, that is "dah dit dah". Including the one-unit gaps inside the character, the letter takes 9 units of time to send, where one unit is the length of a dot.
In the classic frequency count of English text, K is the 22th most common letter. It is one of the rarer letters in English, so it can wait until you are comfortable with the common ones. You will mostly meet it in names, call signs and abbreviations. When spelling over the radio, operators call it "Kilo" using the NATO phonetic alphabet, which works alongside Morse rather than replacing it.
To send K with a flashlight, keep the light on for one count per dot and three counts per dash, with the light off for one count between them; the light signaling guide has the details. To tap it, use a short tap for each dot and a longer press (or a knock-and-hold) for each dash, as explained on the tapping page. Whatever the medium, the rhythm "dah dit dah" is what makes it K.
