Which of the following would be a symptom of malfunction in a 2182 kHz radiotelephone system that must be reported to the Master and logged?

• A. No indication of power output when speaking into the microphone
• B. Distorted audio but power output visible
• C. Regular carrier but no audio
• D. Intermittent beeps on transmission

Answer: (A)

On 2182 kHz radiotelephone, any malfunction that affects the ability to use the MF voice channel must be reported and logged. If there is no indication of power output when you speak into the microphone, it means the transmitter isn’t producing RF output at all. No RF power means you cannot communicate on the distress/calling frequency, which is a serious fault that requires immediate notice to the Master and documentation in the ship’s log. Other symptoms—distorted audio with power present, a regular carrier but no audio, or intermittent beeps—show problems in the audio or modulation paths or intermittent transmit faults, but the critical, must-report condition is the complete loss of RF output.
