What is the minimum receiver sensitivity required for a Survival Craft Transceiver?

🔍 Key Concepts

• SOLAS requirements for survival craft two-way VHF radiotelephone apparatus • The definition of receiver sensitivity in radio communications equipment • Typical sensitivity values (in microvolts) for modern marine VHF receivers and why survival craft sets must meet a minimum standard

💭 Think About

• Think about why survival craft transceivers must have a certain minimum sensitivity. How does this affect the ability to receive weak distress or coordination signals? • Compare the listed microvolt values with what you would expect for a reasonably good but simple emergency VHF receiver. Which options seem unrealistically strict or too insensitive? • Consider how international standards tend to choose round, practical figures that equipment manufacturers can reliably achieve.

✅ Before You Answer

• Verify in the relevant SOLAS chapter and associated IMO performance standards for survival craft VHF radiotelephone apparatus (LSA Code / IMO resolutions). • Check the exact unit: the standard specifies sensitivity as the r.m.s. (root mean square) value of the RF input in microvolts for a given SINAD or signal-to-noise condition. • Make sure you distinguish between transmitter power output and receiver sensitivity; only the latter is being asked about here.
