Looking for guidance. I received a pre-programmed APX 7000 which had three separate P25 trunking systems in it. All was tested and working fine. I copied the codeplug and saved it, then added one talkgroup to one of the profiles. After I sent the modified codeplug back to the radio and turned to that talkgroup I got a Sys Reg Refused message on that talk group and every other TG on that same system. I then opened the original codeplug and sent it back to the radio, still shows reg refused on all TG's on that particular system.
Any help would be appreciated.
