Radio shorthand for ‘I received and understood your transmission,’ heard most often as ‘copy loud and clear.’ Unlike a bare acknowledgement, it confirms the words were actually made out, not just that a signal arrived.

To key it right, hold every dash three times as long as a dot. Leave a short three-unit breath between letters; the slash is the long, seven-unit pause between words. Want to hear it slower or flash it as light? Open it in the morse code translator.
