What does OVER indicate in radio communications?

• A. Sender ended transmission and needs response.
• B. Sender ended transmission and needs no response.
• C. Radio is in maintenance mode.
• D. Channel is busy.

Answer: (A)

In radio talk, saying “over” signals that you have finished speaking and you expect a reply. It’s how the speaker hands the conversation to the other person in a half‑duplex channel, so the listener knows to respond rather than start talking immediately. For example, you might say your message and end with “over,” and the other party responds with their message and typically ends with their own “over” to pass back control. This isn’t about the channel being busy or the system being in maintenance—that would be indicated by different status cues or procedures.
