I've been running Unitrunker on the Jefferson Co 911 control channels more frequently now. There are some talkgroups on the system that are not documented in the RRDB since it is unknown what they are for.
You can find more info about it at http://wiki.radioreference.com/index.php/Jefferson_County,_Ohio - Just look at the section titled Unknown Radio IDs and/or Talk Groups.
In that chart you'll see one or more radio IDs that were seen using that talkgroup, the unknown talkgroup, other unknown talkgroups that radio ID might have used/affiliated with, other _known_ talkgroups that the same radio has used or affiliates with.
3472
6736
6896
7024
7056
8080
8240
You can possibly venture a guess as to whether an unknown talkgroup is police, fire, EMS, other based upon what radio ID was on that talkgroup and what other talkgroups that radio ID had used.
So for those of you who run closed mode, you might want to add these talkgroups just in case. They have been seldom used or not used at all in the past two weeks... but they do exist.
