🔍 Key Concepts

• Receiver sensitivity is about how well a radio can pick up weak signals • Understand what each control (regeneration, audio frequency, radio frequency, beat frequency oscillator) actually adjusts in the receiver • In a 3 circuit receiver, pay attention to which stage handles RF (radio frequency) input vs. audio output or demodulation

💭 Think About

• Which control would most directly affect the strength of the incoming RF signal before it is converted to audio? • Which of these controls mainly affects the loudness or tone of what you hear rather than how weak a signal the set can detect? • Which control is primarily associated with CW/SSB reception (fine tuning the audio tone) rather than overall receiver sensitivity?

✅ Before You Answer

• Be clear on the difference between RF gain/sensitivity and audio volume/tone • Identify which control is normally used to adjust reception of very weak distant stations • Eliminate any controls that mainly affect audio characteristics (volume/tone) rather than RF front-end gain
