Which of the following would cause your FM transmission audio to drop out on voice peaks?
Your repeater offset is inverted
Your FM deviation is too low
You are talking too loudly✓Bonne réponse
Your transmit power is too high
Explication
Speaking too loudly overdrives the FM modulator, and the transmitter's deviation limiter clips the loudest parts, so audio disappears exactly on the peaks. Too little deviation makes you quiet rather than intermittent, and transmit power does not affect audio processing.
