What does the Q code QSM mean?

• A. Stand by
• B. Time
• C. Location
• D. Repeat your message

Answer: (D)

In radio communication, Q codes are a compact shorthand for common actions, helping crews exchange messages quickly. QSM specifically means you’re requesting the other person to repeat their message. You’d use it if you didn’t catch something clearly due to noise, garbling, or a fast transmission, so you want the speaker to go over it again. That’s why the best choice is “Repeat your message.” The other options describe different actions (stand by, time, location) which are handled by other Q codes, not by QSM.
