Squelch - Uniden uh078sx Operating Manual

SQUELCH

The squelch is used to eliminate any annoying background noise when there
are no signals present.
Make sure to first select a channel not in use before setting the
squelch in your uh078sx UHF-CB radio.
Think of squelch as a gate. Turn [SQ] fully
clockwise. This raises the "Squelch Gate" so high
that only the very strong signals can get through.
Turn [SQ] fully counter clockwise until you hear a
hiss. This opens the "Squelch Gate" so that
everything gets through noise, weak signal, and
strong signals.
To set the "Squelch Gate" to the desired level, turn
[SQ] counter-clockwise until you hear noise. Then
turn the [SQ] clockwise just until the noise
stopped. Now only the desired signal can get
through.
If an incoming signal is very weak there is a
possibility that you will have a choppy or broken
reception, due to the sensitivity of the squelch.
In this case, simply rotate the [SQ] clockwise
until the weak signal is heard clearly.
