Which of the following would cause your FM transmission audio to drop out on voice peaks?
C
Answer
Operating procedures and emergency communications
Type
A
Your repeater offset is inverted
B
Your FM deviation is too low
C
You are talking too loudly
D
Your transmit power is too high
Answer Notes
In frequency modulation (FM), the amplitude (volume) of your voice directly controls the amount of frequency deviation. If you talk too loudly or hold the microphone too close to your mouth, your signal's deviation will become too wide and exceed standard bandwidth limits. Most modern repeaters and receivers have protective circuits or narrow filters that will simply cut off (clip or drop) the audio when it swings too far off the center frequency.
This results in your audio dropping out right at the loudest moments, known as voice peaks. The distractors describe unrelated issues: low deviation makes you sound quiet rather than dropping out, an inverted offset prevents repeater access entirely, and high transmit power affects signal strength but does not cause audio clipping.
