What does 10-1 mean in OPP radio communications?

• A. Unable to copy due to poor or no transmission.
• B. Acknowledgement; message received and understood.
• C. Stop transmitting; return to listening.
• D. Location of the officer or incident.

Answer: (A)

In this radio code system, 10-1 is used to indicate a reception problem: you cannot copy the transmission because the signal is poor or there is interference. It’s a precise way to tell the other party that what was sent isn’t coming through clearly, so they should repeat, speak more slowly, or switch to a clearer channel. This makes sure everyone understands you’re not hearing the message, not that you’ve heard or acknowledged it. Think of it as a quick check to prevent miscommunication. If someone hears 10-1, they’ll typically respond with a repeat or ask to recheck the channel. This is different from signals that indicate the message was received or that you should stop transmitting, or from codes that relay location.
