What is the definition of the term “receiver desensitizing”?

🔍 Key Concepts

• Receiver sensitivity in a VHF or HF radio system • Effect of strong nearby signals on a receiver’s ability to hear weak signals • Difference between squelch/AF gain settings and actual receiver performance

💭 Think About

• Ask yourself: which choice describes a situation where the radio cannot pick up weak signals because something is overwhelming or overloading the receiver front end? • Which options are just about how you set the controls (like squelch or AF gain), and which are about an external signal affecting receiver performance? • Think about what the word "desensitizing" literally means for the receiver: is the radio being made less able to sense weak signals, and if so, what is causing that?

✅ Before You Answer

• Identify which option involves a strong signal on another/nearby frequency affecting your ability to hear weak signals. • Eliminate options that only describe operator control settings (squelch or AF gain) and not a technical effect on the receiver’s sensitivity. • Confirm that the correct definition involves a reduction in sensitivity to weak signals, not just a temporary noise burst.
