Which of the following conditions would indicate the malfunction of a 2182 kHz radiotelephone system?

🔍 Key Concepts

• 2182 kHz as the international radiotelephone distress and calling frequency • Normal vs. abnormal propagation and noise characteristics on MF (medium frequency) bands day vs. night • What a visual power/antenna indication tells you about transmitter vs. antenna issues

💭 Think About

• For each option, ask: could this be caused by normal radio propagation and traffic patterns rather than equipment failure? • Which choice points to a direct, observable problem in the transmitter/antenna system itself, independent of distance or time of day? • Is the situation described something you would expect regularly on a properly working MF radiotelephone, or is it clearly abnormal?

✅ Before You Answer

• Distinguish between propagation/traffic issues and actual equipment malfunction • Think about how distance and time of day affect MF communication range and background noise • Focus on any option that shows an immediate, measurable problem with the radio’s output to the antenna, not just lack of received traffic
