🔍 Key Concepts

• How a volume control on a receiver works (audio loudness vs. receiver sensitivity) • Difference between volume (audio gain) and receiver sensitivity (RF/IF gain or squelch) • What control usually affects the minimum signal level that can be heard (threshold)

💭 Think About

• Ask yourself: does turning the volume up actually let the receiver pick up weaker radio signals, or just make whatever is already received louder? • Which control on typical marine radios is used to decide whether weak/noisy signals are heard or muted: is it labeled volume, squelch, or something else? • If you turn the volume all the way down, does the receiver stop receiving signals, or do you just stop hearing them in the speaker?

✅ Before You Answer

• Distinguish clearly between audio loudness and radio sensitivity—they are not the same thing. • Think about what control typically sets a signal threshold on a marine VHF (usually called squelch): is that the same as volume? • Verify which statement, if any, says that volume directly changes receiver sensitivity, not just how loud the audio output is.
