I did a brief sweep of the Philadelphia P25 municipal system (Zone 1, site 3) this morning and found a number of talkgroups that aren't listed in the database. They seem to be quite active. I have no authoritative information on what they are for, but I have some notes on some of them.
Anyway, for what it's worth:
