The purpose of the squelch is to mute (squelch) the audio when no (or too low) signal is present. A typical problem in that model of scanner is an open squelch potentiometer, but that is not the only thing which can cause what you describe. You could take the scanner to Radio Shack and they will give you a quote on repairing it, usually a flat rate. Otherwise someone would need to look at the signals and troubleshoot what is wrong.
