🔍 Key Concepts

• Amplitude modulation (AM) and how the carrier, sidebands, and audio drive relate • How overmodulation, mistuning, or instability can affect carrier amplitude • The difference between insufficient vs. excessive RF or audio drive in a transmitter

💭 Think About

• Which choices describe conditions that could make the carrier swing higher than normal rather than just drop or distort? • For each option, ask: does this fault tend to cause unsteady/erratic changes in carrier level, or a steady positive shift? • Could more than one of these conditions be present at the same time, and if so, would they tend to increase or decrease the carrier amplitude?

✅ Before You Answer

• Identify which options involve too much drive versus too little drive • Consider how incorrect tuning or neutralization in RF stages typically shows up on an RF wattmeter or modulation monitor • Verify which conditions are likely to create spurious signals and carrier overshoot (positive shift) rather than simple loss of output
