What does code 10-37 Operator on duty mean?

• A. Inappropriate radio traffic
• B. Operator on duty
• C. Check registration & DL
• D. Emergency traffic

Answer: (B)

Code 10-37 is a status update: it signifies that the operator is on duty. In the 10-code system, this phrase is used to quickly confirm that the operator is actively monitoring the channel and available to handle calls or coordinate responses. It’s about duty status, not about a specific action or type of traffic. That’s why it’s the best fit for the meaning of 10-37. The other options describe different situations (unrelated to the operator’s current duty status), so they don’t match the purpose of this code.
