Mystery CenCom STARCOM21 Talkgroups

[kevino]

There is a group of "mystery" SC21 talkgroups that appear to be affiliated with CenCom E9-1-1 dispatch (Round Lake Beach). From the notes below, they seem to be primarily used by Fire/EMS agencies in that area, possibly as tactical ops/fireground channels:

• TG 1876 - CenCom TG? "Mobile"?
• TG 1877 - Barrington FD use (1/21) - CenCom fire TG?
• TG 1878 - Rolling Meadows FD Engine 15 calling CenCom, IDing TG as ____ Region Fire (7/14), RIDs 71100 and 71999 - T102 (8/16), RID 71692 (T149, 8/22/16), affiliated by Barrington FD? RID 71361 (T149, 8/16)- CenCom fire TG?
• TG 1879 - CenCom fire TG?
• TG 1880 - Site 115/149; T101 10/18/13
• TG 1893 - Site 149 (5/26/15 RID 71093) Site 108 (6/2/15) - Barrington-Countryside FPD? CenCom? affiliated by BCFPD RID 71073 (8/16)
• TG 1894 - Site 149 (10/18/13) - Barrington-Countryside FPD? CenCom?
• TG 1895 - Site 149 - Barrington Countryside FPD? Encrypted (5/15) CenCom?
• TG 1896 - Site 149 - Barrington Countryside FPD? Encrypted (5/15) CenCom?

None of these talkgroups have been identified by name, and I'd like to get them out of the SC21 wiki and into the database. Can anyone identify these talkgroups (and possibly others that might be in this general range that have not been discovered yet)?

1876 has been used for PD dispatch in the past but I haven't seen it used often and not for a long time now, it is mostly used at night for some reason. 1877 was used in the last couple days for regular fire dispatch. Both these talkgroups I had seen in Phase I but are now showing Phase II. I have 1878 labeled as citywide but I don't remember where I got that from, possibly meeting minutes from NWCDS back when they'd print the specific talkgroups when they had a request for access. I've got affiliations from Barrington radios on 1879-1882 but only encrypted voice traffic on 1879, nothing on the rest. Barrington-Countryside has at least TG 1891-1896, with 1894-1895 showing encryption, would assume 1896 is too but I don't have any voice hits to know for sure.
