If a ship radio transmitter signal becomes distorted, what is the proper action?

• A. Cease operations.
• B. Continue transmitting at reduced power.
• C. Switch to a different frequency.
• D. Increase transmitter power and modulation.

Answer: (A)

When a ship’s radio signal is distorted, the priority is to stop transmitting to avoid causing interference and to allow you to diagnose the problem. Distortion often means the modulation or the equipment path isn’t functioning correctly, which can degrade communication and upset other operators on the same or adjacent frequencies. By ceasing transmission, you prevent further trouble while you inspect the transmitter, microphone, audio chain, and modulator, and correct any fault. Continuing to transmit—even at lower power—won’t fix the distortion and can still cause interference. Switching to another frequency doesn’t address the root cause and may create new interference. Increasing power and modulation would typically worsen the distortion and could violate equipment limits.
