I just bought a new Uniden BCD996P2 and used radio reference to program it. All the systems work fine included conventional systems, LTR, and EDACS however non of the P25 systems are working. They around from surrounding counties but one county is only 25 miles away and the other is 41 miles away. Does anyone have any clue as to what I might be doing wrong or are the systems just too far away to reach me?
