What should you do before calling CQ?

Before calling CQ, it is essential to follow proper protocol to ensure that you are operating correctly and considerately within the amateur radio community. Listening first to the frequency allows you to determine if someone else is already using the channel, thereby avoiding interference and maintaining good operating practices. It’s also important to ask if the frequency is in use, particularly if you suspect that someone might be using it, as this can encourage courteous interactions among operators.

Additionally, verifying that you are authorized to use a specific frequency is crucial, as each amateur radio operator must adhere to regulations governing their license class, including the bands they may operate on. By confirming your authorization, you ensure compliance with laws and regulations that govern amateur radio operation.

Together, these precautions foster a respectful environment on the airwaves and help uphold the integrity of amateur radio as a service. Hence, all choices presented encompass essential steps to take before making a CQ call, solidifying that they are collectively the correct response.
