BEADWINDOW alerts require a concise acknowledgment and termination of the transmission to prevent discussion of sensitive information on the air. The best response is to indicate you heard and understood the alert and then end the transmission. Saying “Roger, out” does exactly that: “Roger” confirms you’ve received the alert, and “out” signals that you’re closing your transmission so no further talk on the restricted topic occurs.

Saying only “Over” would imply you’re continuing the conversation, which isn’t appropriate after a BEADWINDOW alert. “Standby” suggests you’re waiting for further instruction rather than ending the transmission. A simple “Roger” acknowledges receipt but doesn’t indicate the transmission is being terminated, which could leave the channel open to discuss restricted information.
