Over the past month or so I've been picking up activity via a wildcard object on my Unication on talkgroup 630 on Philly TRS Zone 1. It sounded like one of the college police departments but I wasn't able to identify who it was. Last night a priority call came across that talkgroup for an address on Spring Garden St and from that I was able to easily identify it as Drexel University Police. The dispatcher mentioned the incident went out over the 16th District and I do know that Drexel Police Dispatch has access to Philly's CAD. Base RID was showing as 11852 with other users in the 118xx range. It sounded like some or all users are patched from Drexel's DMR frequency as some of the officers were coming across with the base RID. I'd suspect Drexel may be in the process of migrating the police over to the Philly TRS but I can't confirm for sure. If anyone knows more please feel free to share. For now I'll make the database submission.
