Which statement correctly contrasts the meanings of OVER and OUT in radio communications?

• A. OVER signals the end of the transmission with awaiting a response; OUT signals the end with no expected response.
• B. OVER indicates a message is being delivered; OUT indicates a request for repetition.
• C. OVER indicates end of transmission with a request for a response; OUT indicates end with no response expected.
• D. ROGER confirms that the message was heard.

Answer: (C)

In radio communications, how you end a transmission tells the other person whether you expect a reply. The word you choose is what signals the next turn in the conversation. Saying that you’re finished speaking and that you want a response is done with the term that means you’ve ended your transmission but expect the other party to respond. In contrast, using the term that you’re finished and do not expect a response signals that the exchange is closed unless you initiate again later. A good way to grasp it is to think of it as a one-on-one turn-taking signal: over ends your turn and invites a reply; out ends your turn and invites no immediate reply. For example, you might say your message and finish with over, then the other unit will respond. If you finish with out, you’re indicating the conversation on that channel is complete. ROGER is separate; it means you’ve heard and understood what was said, not that the speaker is ending the conversation.
