From experience I would guess that you don't have ALL OF the frequencies that the system is using (programmed into your scanner). In particular if you are missing one of the "control channels", (or even if it is locked out), and they CYCLE between one of more from day to day (easier on the duty cycle of the transmitters), then the day they are using one you DON'T have, you won't hear anything.

I'd go to this link and find the system, then see if you're missing anything


Could you tell me why my scanner is only picking up part time? Someday it will scan and pick up call and other days it won't. It is no set day's or time. Bearcat 346Xt. I have your software.
