The noise limiter should be adjusted to reduce what kind of noise while receiving?

• A. Static
• B. Hum
• C. Whine
• D. Buzz

Answer: (A)

Noise limiters target the random, crackling noise that often accompanies weak or distant transmissions—this is the static you hear on the radio. By smoothing out those rapid, unpredictable fluctuations, the audio stays clearer and easier to understand. Hum, whine, and buzz come from other sources like power-line interference, engine or generator noise, or electrical interference, and they aren’t addressed by a noise limiter in the same way. So the device is used to reduce static while receiving.
