I have an edacs/Provoice system where I live that I know my 396XT can't listen to. But its in the database I downloaded to my scanner from RR. When I sit on that channel (if that's what its called) shouldn't I at least be able to hear something whether its garbled voice, or just a control channel noise? I sit on the 3 channels for Thunder Bay Police and there's not a sound from the scanner. Is this normal?
