Which line ends a transmission with 'out'?

Which line ends a transmission with 'out'?

• A. (your call sign), out
• B. (the person’s call sign), over
• C. (your call sign), over
• D. (the person’s call sign), out

Answer: (A)

In radio communications, you use “over” to signal that you’re done speaking and are waiting for a reply, while “out” shows the transmission is finished and no response is expected. When you sign off, you identify who is ending the transmission by saying your own call sign, followed by “out.” That clearly marks you as the station that is closing the contact. So the line that ends with “out” and uses your own call sign is the correct form. Lines that end with “over” expect a response, and lines that end with someone else’s call sign don’t correctly indicate who is closing the transmission.
