I am trying to set up the Fauquier / Culpeper / Rappahannock System in my Uniden BCD396XT with no luck so far. It seems like I'm getting a strong signal but no audio when it scans the system i loaded. I set up Prince William County in a similar way and pick up plenty from their police dispatch. I'm sure I'm doing something wrong and any advice would be appreciated. I'm completely new to digital scanners.
