🔍 Key Concepts

• Continuous Wave (CW) reception and how beat frequency audio is produced • Purpose of a tuned audio frequency amplifier in a receiver • How selectivity in the audio stage affects interference from nearby signals

💭 Think About

• When receiving CW, what do you actually listen to: the RF carrier itself, or an audio tone created in the receiver? • If you tune the audio amplifier to a narrow range of frequencies, what happens to signals (and noise) outside that range? • Which choice, if true, would improve the clarity and ease of copying CW signals?

✅ Before You Answer

• Be clear on what "desired audio beat frequency" means in CW reception • Decide whether a tuned audio amplifier would boost or attenuate the desired CW tone • Check which options describe reducing unwanted signals versus weakening the tone you want to hear
