🔍 Key Concepts

• RF gain control function on a receiver vs. the AF (audio) volume control • Effect of RF gain on receiver sensitivity to weak signals • Difference between changing feedback/coupling between stages and simply changing how much signal reaches the RF amplifier

💭 Think About

• When you turn RF gain down on a receiver, what happens to very weak incoming signals compared to strong ones? • Which control (RF gain or volume) actually changes how loud the speaker is versus how much radio signal the receiver is allowed to work with? • If sensitivity decreases, what practical effect would you notice when trying to copy a distant station?

✅ Before You Answer

• Be clear on the difference between RF gain and audio volume controls • Think about whether RF gain acts before or after the RF amplifier stage in the signal chain • Check which option directly describes a change in sensitivity of the receiver to incoming RF signals rather than internal circuit coupling or feedback.
