🔍 Key Concepts

• Strong nearby transmitter effects on weaker signals in a receiver • Difference between intermodulation, cross-modulation, and capture effect • How a very strong station can make you hear its modulation on other frequencies

💭 Think About

• Which option specifically describes a very strong station causing its modulation (voice or signal content) to appear on other frequencies you are trying to receive? • Which phenomenon involves a strong signal overriding or riding on top of weaker signals, rather than just making the receiver quieter or locking onto one signal? • Think about what happens when you tune around and keep hearing the same strong station’s audio on multiple nearby channels—what is that called?

✅ Before You Answer

• Check which term mentions or implies modulation from one signal appearing on another channel. • Eliminate any choice that mainly refers to noise reduction or making the receiver sound quiet when a strong signal is present. • Differentiate between effects inside the receiver front end (mixing products) and one signal’s modulation being imposed on another.
