Question 280

What might be a problem if you receive a report that your audio signal through an FM repeater is distorted or unintelligible?

  1. Your transmitter is slightly off frequency
  2. You are speaking too loudly or too close to the microphone
  3. You are in a bad location
  4. All these choices are correctCorrect answer

Explanation

All three produce audio that arrives distorted or unreadable: an off-frequency transmitter is imperfectly demodulated by the repeater receiver, excessive microphone level or speaking too close over-deviates and clips, and a weak or multipath location gives the repeater a noisy signal to retransmit. Since each alone explains the report, the combined choice is correct.
