What would be considered a normal sensitivity for 10 db of quieting in a VHF marine receiver?

Question 1 of 27070

What would be considered a normal sensitivity for 10 db of quieting in a VHF marine receiver?

🔍 Key Concepts

• Receiver sensitivity – how small a signal (in microvolts) the receiver can still process usefully • 10 dB quieting – the point where the noise drops significantly when a signal is applied • Typical sensitivity range for modern VHF marine receivers as listed in equipment specs

💭 Think About

• Think about whether high-quality receivers should require a larger or smaller input signal (in microvolts) to achieve 10 dB quieting • Compare the answer choices: which values would indicate a more sensitive receiver, and which indicate a less sensitive receiver? • If you looked at a typical VHF radio datasheet, which order of magnitude (tenths, ones, or tens of microvolts) would you expect for a modern, good-quality set?

✅ Before You Answer

• Remember that greater sensitivity = smaller required signal voltage (in microvolts) for the same quieting • Check which answer choices fall into a realistic range for modern marine VHF receiver sensitivity—eliminate any that seem clearly too insensitive • Verify the order of magnitude (0.1 vs 1 vs 5 vs 10 microvolts) that is generally quoted for 10 dB quieting in tech specs
