Been catching some unidentified talkgroups on the MPSCS system the last couple days. I monitor the Holly tower.

IDs: 14599, 16647, 27911, 37127, and 55559.

Any ideas what they are? I have a hypothesis... are they data or regroup channels or something of that nature? They appear only for a moment when scanning, have no audio or encrypted audio that I can tell.
