In the given code set, what does 10-1 mean?

• A. In service
• B. Requesting backup
• C. Receiving poorly
• D. All clear

Answer: (C)

In this radio code set, meanings are tied to how the transmission sounds or the status of the radio link. The code with the value 1 in the second position is used to indicate poor reception. So “receiving poorly” describes that the message isn’t coming through clearly, and you need the other person to repeat or you should check your equipment or move to a better location to improve the signal. This is why it fits best: it’s about the quality of the communication itself, not about being in service, calling for help, or declaring the scene clear. “In service” is a different status of availability, “requesting backup” signals a request for assistance, and “all clear” conveys a status of safety or completion. None of those describe signal quality. When you hear or use a 10-1, you’re flagging that the transmission isn’t being copied well and needs attention to restore clear communication.
