In most cases the default SQUELCH setting of 0.5dB is sufficient
and should not be adjusted. However, if users experience RF noise
interference and disruption to the audio signal users can adjust the
SQUELCH to help reduce the interference. Users can choose between
00 – 25dB of squelch. Adjusting SQUELCH would be a last resort in resolving
an RF noise interference problem.
It’s recommended to try a different group or channel or use the AUTO scan function to find an interference
free channel.
