Correct Answer: C
Explanation
Distorted or garbled audio in an FM transmission is often a sign of over-deviation, which is usually caused by talking too loudly or positioning the microphone too close to your mouth. In FM (Frequency Modulation), the loudness of your voice determines the frequency swing, known as deviation.
If you speak too loudly, the deviation exceeds the design limits of the radio, causing the signal to be transmitted too wide for the receiver to properly process. This results in clipped and garbled audio. The solution is simply to talk a little softer or move the mic farther away (T7B01).
