How do you perform a proper radio check?

Performing a proper radio check is essential for ensuring communication equipment is functioning correctly within maritime operations. Making a call on channel 16, which is the international distress and calling frequency, is standard practice. By asking for clarity from anyone monitoring that channel, you are effectively testing not just your ability to transmit, but also confirming that someone can receive and understand your transmission. This procedure helps ensure that both your radio and the communication protocols are working effectively, which is critical in emergency situations.

The other methods outlined do not conform to standard practice in radio communications. Randomly calling a frequency lacks structure and may interfere with other communications. Testing the radio without initiating a call fails to engage other operators and does not confirm if your signal is being received clearly. Lastly, waiting for someone to contact you first does not verify your ability to transmit effectively, which could be a significant issue if you needed to initiate emergency communication.
