Which term indicates that the transmission is complete and no response is expected?

• A. Over
• B. Read Back
• C. Pan Pan
• D. Out

Answer: (D)

In radio communications, you signal whether a response is expected by the closing phrase you choose. The term indicating that your transmission is finished and no reply is needed is the one used to declare the channel closed for that exchange. It tells everyone listening that you’re done talking and don’t expect a response unless you initiate again. This differs from the other phrases: another word means you’ve finished speaking but are expecting a reply, which is why it’s not the right choice here. Read Back is used to ask the other station to repeat back the exact message for accuracy, not to indicate no further response. Pan Pan is a distress signal, used to indicate an urgent emergency. So, using the term that means “I’m done; no response needed” aligns with the scenario described.
