🔍 Key Concepts

• Single Sideband (SSB) radio power draw during voice transmission • How AC or DC indicator lamps can react to changing RF or audio loads on a boat • Difference between normal behavior of an SSB when modulated by voice vs signs of a fault

💭 Think About

• When you speak into an SSB microphone, what happens to the transmitter’s output power with each syllable, and how might that affect other electrical indicators on the panel? • Which panel devices are most likely to show obvious, visible changes in step with your voice: meters, lamps, or tuners? • Think about what an "automatic tuner" is designed to do: does it normally adjust continuously with each word, or mostly when you first key up or change frequency?

✅ Before You Answer

• Identify which option describes something that would visibly respond in real time with each syllable for a voice‑modulated RF signal. • Eliminate any choice that would normally occur only once per transmission or when changing frequency, rather than on every word. • Consider normal behavior of boat voltage and current indicators: which one is both sensitive and obviously noticeable flickering with your voice?
