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.
