Which code means Repeat?

• A. 10-1
• B. 10-9
• C. 10-2
• D. 33 Clear radio for emergency traffic

Answer: (B)

In radio communications, there is a specific code used to request that the other party repeat what they just said. This code is used to ensure you clearly hear the exact message, which is crucial when information is time-sensitive or complex.

Why this is the best choice: it communicates a precise action—asking the other person to resend their last transmission—without ambiguity. It helps keep the channel accurate and efficient, reducing the chance of miscommunication on the scene.

The other options refer to different radio states: one indicates poor reception or that you can’t copy the message, another means the signal is good and you can proceed, and another signals emergency traffic that takes priority. None of these ask for a repetition, so they don’t directly address the need to hear the last transmission again.
