I typically just scan a few opp talkgroups, Cambridge, Wellington, & Sebringville. Recently they stopped working so I put my bcd996xt in search mode & now I receive them but the ID's appear different. They are all off by 4. The database shows Cambridge as 8704 but I'm getting it on 8707. Same with the others, all off by 4. Did something happen to my programming or did the ID's actually change. Any ideas?
