What should you do before calling CQ?
The correct answer is D: All these choices are correct. Before calling CQ, you should listen first to ensure the frequency is clear, ask if the frequency is in use if you're uncertain, and make sure you're authorized to use that frequency for your license class. All three are good operating practices.
Listening first prevents interfering with ongoing communications. Asking if the frequency is in use (saying 'Is this frequency in use?') is courteous and ensures you're not interrupting. Verifying you have privileges for the frequency ensures you're operating legally. These practices demonstrate good operating etiquette and help maintain order on the bands.
Exam Tip
Before CQ = Listen, ask, verify. Remember: Before calling CQ, listen to ensure the frequency is clear, ask if it's in use, and verify you have privileges for that frequency. All three are good practices.

You also verify that as a Technician, you have privileges on 146.52 MHz (which you do). Only then do you call CQ. This demonstrates good operating practice.
