Question T2A12
From subelement T2 - T2A
What should you do before calling CQ?
Why is this correct?
All three choices are essential pre-CQ steps that prevent interference and ensure legal operation. You must verify frequency authorization (Part 97 privileges), listen to detect ongoing QSOs, and ask if the frequency is in use since stations may have paused temporarily. Skipping any step risks interfering with other amateurs or operating illegally.
Memory tip
For 'All these choices are correct' questions, look for comprehensive protocol lists where each option addresses a different potential problem. Here: authorization prevents legal violations, listening catches active conversations, and asking catches paused QSOs. Complete procedures require multiple safeguards.

This three-step protocol reflects amateur radio's self-policing culture and spectrum sharing responsibilities. Frequency privileges define where you can transmit, but good amateur practice goes beyond legal minimums. The 'ask if frequency is in use' step acknowledges that SSB and other modes lack carrier detection, so stations may be present but momentarily silent between transmissions. Professional operators always verify clear frequency access before initiating new contacts.
Think about it
Why do you think amateur radio relies on operator courtesy rather than automated systems to prevent frequency conflicts?
