🔍 Key Concepts

• VHF-FM radio receiver behavior when two signals are on or near the same frequency • How a receiver treats strong vs. weak signals that arrive at the same time • Difference between accepting multiple signals and locking onto one

💭 Think About

• If two stations transmit at the same time on the same VHF channel, what does the receiving radio usually let you hear? • Which choice describes the radio favoring one signal over another, and is it the weaker or the stronger one? • Which options can you rule out because they talk about behavior that normal marine VHF receivers do NOT do?

✅ Before You Answer

• Be clear on whether the effect involves one dominant signal or several signals at once • Decide whether the receiver prefers the strongest or the weakest overlapping signal • Eliminate options that describe functions a normal marine VHF receiver cannot perform, such as modulating another transmitter
