What does it mean to 'repeat' a transmission in radio communications?

• A. Translate the message into another language.
• B. Request the sender to repeat the last message due to poor copy or interference.
• C. Acknowledge receipt of the message.
• D. End the transmission.

Answer: (B)

In radio communications, to repeat a transmission means asking the other party to re-send the last message because it wasn’t heard clearly—there was poor copy, static, or interference. This ensures you don’t act on misheard instructions and keeps everyone on the same page, which is crucial for safety and accuracy.

The other options don’t fit because repeating isn’t about translating the message into another language, nor is it simply acknowledging that you heard something (that’s more like copy/roger). It isn’t about ending the transmission either (that would be ending the call). The purpose of asking for a repeat is to obtain a clearer retransmission of the previous message.
