What does code 10-30 stand for?

• A. Standby
• B. Inappropriate radio traffic
• C. Emergency traffic
• D. Confidential information

Answer: (B)

Code 10-30 signals inappropriate or unnecessary radio traffic. It’s a notice to curb nonessential chatter and keep the airwaves clear for urgent and important messages. This focus on channel discipline is why it’s the best fit: it directly communicates that the transmission isn’t appropriate for the radio during active operations. Standby means waiting for instructions, emergency traffic refers to high-priority transmissions, and confidential information implies restricted content rather than a radio-use cue.
