What is meant by "full quieting" in a FM VHF receiver?

🔍 Key Concepts

• FM VHF receiver behavior as signal strength increases • Meaning of receiver background noise and how it sounds when no signal is present • Basic idea of SINAD (Signal-plus-Noise-and-Distortion) and what “quieting” suggests

💭 Think About

• When you slowly increase a received signal from very weak to very strong, what happens to the hiss/background noise you hear on an FM receiver? • Does “full quieting” sound more like a small change or a point where something is essentially gone or masked? • Which options describe changes as signal level goes up vs. down, and which one directly describes the condition of the receiver at that moment?

✅ Before You Answer

• Identify which answers talk about adjusting a control vs. a condition of the received signal. • Note which options describe behavior as signal level changes (increasing or decreasing) rather than a specific quiet state. • Focus on the choice that directly describes the receiver’s audio when the signal is strong enough that background noise is no longer heard.

What is meant by "full quieting" in a FM VHF receiver?

Adjusting the squelch control to eliminate background noise.

The rapid decrease in SINAD and noise with increasing signal level.

The received signal is strong enough to completely quiet the receiver background noise.

The rapid improvement in SINAD and decrease in noise with decreasing signal level.
