Welcome to RR. You should be able to get answers to questions here. In this case, it should have a system or band programming option for P-25 APCO, or see if it is on this list: Categoryigital Scanners - The RadioReference Wiki
I think the Uniden digital models have Trunktracker IV on the front and the Radio Shack models have Digital trunking. Hope this helps and welcome to the site.
