How is squelch adjusted so that a weak FM signal can be heard?
Set the squelch threshold so that receiver output audio is on all the time✓Correct answer
Turn up the audio level until it overcomes the squelch threshold
Turn on the anti-squelch function
Enable squelch enhancement
Explanation
Squelch mutes the receiver until the signal exceeds a set threshold, so a weak signal below that threshold is silenced. Backing the threshold off until the receiver noise is heard continuously means nothing is being muted, so even weak signals get through.
