Default RS Pro-83 White noise problem

What else could I be missing? Has the radio become defective? It
was purchased new, out of the box.


The squelch output (DC that gets higher as the detected noise gets
higher) feeds 2 points - the computer, so it knows whether to scan or
stop and an audio gate that cuts off the audio when there's no signal.
It sounds as if either the audio gate is allowing signal through
regardless of the state of the squelch output, or the squelch output
isn't getting to the audio gate. How you can check that out without a
schematic (RS schematics of recent products are rare) is the tough
question.
