What does 10-3 mean?

Explanation:
In this code set, a radio directive that uses the number you’re seeing is signaling a specific condition about the channel itself. 10-3 means the channel is restricted. That tells everyone on the system that only authorized personnel should transmit and that general traffic should pause or switch to a different channel. It’s a way to prevent interference and protect sensitive communications during a critical moment or when the channel is reserved for particular units. Think about it as a status of the line rather than a routine action like being in service, taking a lunch break, or relaying a message. Those other states describe different situations, while channel restricted directly communicates how access to the radio channel should be handled.
