Copy That in Morse Code
-.-. --- .--. -.-- / - .... .- -
"Copy that" means "I received and understood your message" — "copy" being long-standing operator slang for successfully receiving a transmission. In Morse it reads -.-. --- .--. -.-- / - .... .- - . On CW, operators more often send a short acknowledgment like R (received) or report how well they're "copying" you, but "copy that" captures the everyday radio sense of confirming you got the message.
Letter-by-Letter Breakdown

| Y | -.-- | dah-di-dah-dah |

| A | .- | di-dah |
| T | - | dah |
Two words. "Copy" runs -.-. --- .--. -.--, dash-heavy throughout, with C, the three-dash O, P, and a Y that ends on dashes. "That" follows with - .... .- -, opening and closing on lone T dashes around the four-dot H and an A. The bracketing T's in "that" — a dash at each end — give the second word a crisp, clipped frame.
How to Send “Copy That” in Morse Code
"Copy that" confirms receipt in radio parlance. On CW you'd often shorten the idea to a quick R or mention your "copy" — for example, telling a station you have "solid copy" (receiving them perfectly) or "partial copy." Sending the full phrase is fine for practice and captures the conversational feel of acknowledging that a message came through clearly.
