What proword is used at the end of the transmission if no reply is required?

• A. Out
• B. Over
• C. Roger
• D. Wilco

Answer: (A)

Ending a radio transmission when no reply is needed is handled by a proword that signals you are finished. Out means you are done and do not expect a response. This tells everyone on the channel that the conversation is closed and no further dialogue is required. In contrast, Over signals that you have more to say and expect a reply; Roger is simply an acknowledgment that you received the message, not that you’re finished or that you’ll act on it; Wilco means you understood and will comply, but it can still be part of an ongoing exchange if more is to come or if confirmation is needed. So the term used to end a transmission with no reply required is Out.
