Q

What is the proper adjustment of the squelch control for maximum sensitivity?

🔍 Key Concepts

• Squelch control purpose on a VHF or HF radio (what it does to background noise) • Relationship between squelch setting and ability to hear weak signals • Difference between too much squelch and too little squelch and how each affects reception

💭 Think About

• If you turn the squelch up until you hear nothing at all, what happens to very weak but important signals? • If you turn the squelch down so low that you constantly hear loud background noise, is that giving you practical maximum sensitivity or just constant static? • Where is the balance point where noise is mostly suppressed but weak signals can still open the squelch?

✅ Before You Answer

• Recall that maximum sensitivity means being able to hear the weakest usable signal, not just making the set quieter. • Think about the exact point on the control where noise stops/starts to be heard and what setting just on one side of that point would do. • Eliminate any choice that suggests the squelch has no effect on what you can hear, since squelch directly affects reception of weak signals.
