Key Concepts
Why Other Options Are Wrong
Option A: Incorrect. Saying your call sign once followed by 'listening for a call' isn't the standard CQ procedure - CQ requires saying 'CQ' multiple times, not just your call sign.
Option B: Incorrect. Saying 'QTC' (I have a message) isn't for calling - that's for indicating you have traffic. CQ is the standard calling procedure.
Option D: Incorrect. Transmitting an unmodulated carrier isn't the proper calling procedure - you need to send 'CQ' and your call sign, not just a carrier.
