Which of the following is NOT a required VHF test during an annual inspection?

🔍 Key Concepts

• Annual VHF equipment performance tests under SOLAS/GMDSS inspections • Typical required checks: frequency tolerance, power output, VSWR, and power source changeover • Difference between transmitter modulation quality tests vs basic safety‑related performance tests

💭 Think About

• Ask yourself: during a safety inspection, what basic things must be proven so the radio will work reliably on distress and safety channels if there is an emergency? • Look at which options are clearly tied to distress channels (Ch. 6, 13, 16) and emergency power, and which one is more of a detailed RF/engineering measurement. • Which test is more about fine‑tuning transmission quality rather than confirming that the set will actually transmit at the right frequency, power, and from the right power source during an emergency?

✅ Before You Answer

• Identify which options confirm the set will transmit on the correct frequencies within tolerance on the main safety channels. • Identify which options confirm the set will transmit with sufficient power and acceptable VSWR and from all required power sources (ship’s supply and reserve/backup). • Check which remaining option is more of a modulation/voice quality measure and not explicitly listed as a standard annual GMDSS VHF performance test.
