“SK” in Morse Code

Sent as one unbroken run — dit-dit-dit-dah-dit-dah — this is the prosign that closes a contact for good: “end of work,” nothing more to send. Hams borrowed it for a quieter meaning too: a fellow operator who has passed away is called a Silent Key.

Letter by letter

Reading it: a dot (·) is one unit long, a dash (−) is three. Letters are separated by a three-unit silence — written as a space — and words by seven units, written as a slash. Want to hear it slower or flash it as light? Open it in the morse code translator.
