Anybody have any idea what exactly this is? I heard an incident last night where Westy, Thornton, Adams County and perhaps others were patched to this TG on an incident. I only heard the TG on the Arv/Westy system and, even though Thorton/ADCOM were using it too, never picked up anything on DTRS MAC channels. I also caught something similar about a week ago involving Westy and Denver on this same channel. I gather it's part of MetroNet, but am surprised I heard no corresponding transmissions on the DTRS given some of the agencies involved. Thoughts?
