🔍 Key Concepts

• Regenerative receiver operation – how regeneration affects sensitivity and when it starts oscillating • Audible effects of oscillation in headphones or speaker when touching parts of the circuit or changing regeneration • Difference between a momentary disturbance (“plop”) and continuous audio changes as the circuit goes into/out of oscillation

💭 Think About

• Think about what happens to an RF/AF circuit when you briefly touch it with a grounded object or your finger. Would this show a change only if the circuit was already oscillating? • How does slowly rotating or moving the regeneration control change the feedback level? What sound would you hear as the detector just starts and stops oscillating? • Which method depends on the circuit already oscillating, and which method can actually make the circuit pass through the oscillation point even if it wasn’t oscillating at first?

✅ Before You Answer

• For each choice, ask: does this method give an audible indication that is different depending on whether the detector is oscillating or not? • Consider whether the regeneration control alone can force the detector in and out of oscillation, producing a characteristic sound change. • Verify that the described “plop” is causally linked to the condition of oscillation, not just any random touch or adjustment.
