Which code would you use to perform a Radio Check?

• A. 10-22
• B. 10-25
• C. 10-33
• D. 10-32

Answer: (D)

Testing radio link quality is the purpose here. When you need to confirm that your radio transmission can be heard clearly by the other unit, you use the radio check code to request a quick verification. The correct choice represents that specific purpose: you send a brief radio check request and wait for a response indicating how the signal comes through. If the other party can hear you well, they’ll confirm that the signal is clear; if not, you can adjust and try again. This ensures reliable communication before sharing important information. The other options refer to separate radio functions (like canceling a call, requesting location, or signaling an emergency), which are not about verifying the radio link.
