🔍 Key Concepts

• Relationship between magnetron current and output power in marine radar • Effect of standing wave ratio (SWR) on transmitter performance • How magnetron heater voltage and external magnets influence magnetron operation

💭 Think About

• When power output drops but the magnetron is drawing MORE current, which kind of fault would cause extra stress or mismatch in the transmitter system? • Which of the listed options would most directly create a mismatch between the transmitter and the antenna system, affecting reflected power? • Think about which items (pulse length, SWR, heater voltage, external magnet) mainly affect efficiency vs. timing or tuning.

✅ Before You Answer

• Verify which condition typically causes high reflected power back into the transmitter line. • Check which fault would show up as increased current draw with reduced radiated power. • Confirm which options mainly affect timing/shape of the pulse rather than overall power transfer efficiency.
