🔍 Key Concepts

• Difference between heterodyne and autodyne reception in RF receivers • How using a separate local oscillator (heterodyne) affects stability and sensitivity • What beat frequency is and how it is controlled in a receiver

💭 Think About

• Think about what changes when the receiver has an independent local oscillator instead of relying on the incoming signal itself. • Which method is likely to give better frequency stability in rough marine conditions and why? • How does each method affect your ability to adjust the audio (beat) frequency for comfortable listening of CW or SSB signals?

✅ Before You Answer

• Compare which method provides greater sensitivity to weak signals and why. • Decide which configuration gives more stable operation when the ship’s power supply and environment are not perfect. • Consider which circuit allows a wider and easier control of the beat frequency using a tuning or BFO control.
