The reception of weak radio signals may be improved by "opening up" the squelch control. What is the normal setting of the squelch control?

🔍 Key Concepts

• Squelch control purpose on a VHF radiotelephone • Relationship between background noise and the squelch setting • How you normally adjust squelch before beginning radio watch

💭 Think About

• Think about what happens if the squelch is turned too far in one direction: do you hear constant noise, or do you miss weak signals? • When you stand radio watch, how do you typically adjust squelch and volume so you can still hear distant calls without constant static? • Which choice describes a position that blocks out just the hiss, but still allows a weak transmission to break through?

✅ Before You Answer

• Identify which option describes setting squelch so that static just disappears, but signals can still be heard. • Check if any option would cause you to miss weak signals entirely; that option is not normal for watchkeeping. • Verify that the normal setting is not at an extreme position (fully open or fully closed).
