SQUELCHThe squelch is used to eliminate any annoying background noise when there

are no signals present.

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.

Make sure to first select a channel not in use before setting the

squelch in your UH076SX UHF-CB radio.
