ISP Restructuring for 2023 Official Thread

[Bhawk27]

Just wanted to thank those doing the heavy lifting to gather all of this info. This has been a great resource. I’m in Troop 2’s area, and I know they’ve completed their D7/D17 consolidation to the primary TG, but I’ll try to contribute with any changes that I may catch going forward.

Glad all of the info looks to be accurate.

Just an FYI, Troop 7 (Old D10) looks to still be utilizing D10 C2C. They were the only troop that didn’t merge, so I would assume they’ll operate slightly different.

"Troop 8" is now being used on air by dispatch. Used on ISPERN broadcasts.

Dispatch is still using "Collinsville" NOT saying "Metro East" as on the maps, etc.
I am still occasionally heard "State Police Litchfield" (This dispatch center "closed" over 5 years ago). Usually it seemed that it was just used when they were still broadcasting of the 155.475 tower in Litchfield/Beaver Dam areas

D11A and B appear to be normal dispatch talkgroups for the former D11 areas. D11C is usually miscellaneous units (but haven't heard much)
D18A appear to be normal dispatch for the former D18 areas.
*EDIT* Now hearing Madison County patrol ops/calls on D18 (I-255 area at least)

Former D18 ISPERN and D11 ISPERN appear to both be used, but I can't figure out when or why
On Site 301 Madison Simulcast (DSD+), 1 or either will broadcast but not both, sometimes with a dispatch talkgroup
(Note, this site only has 6 phase 1 freqs/5 voice paths -- so they could be limiting traffic)
(Note, the D18 talkgroup seems to now always be available on this site, previously only when a unit was in the area)

At first, I thought 8-1xx units were patrolling D18 areas, but not true - many of these are " Training/Probationary"

(new) 8-2xx (203, -207) on D18A "Secure 2 hours", "overweight enforcement at SC-32"
* These appear to be the same type "200" units working at Scales as before

(I currently don't have pro96com hooked up because the radio is in repair, to see if they are patched.)

It would appear they're transitioning to the new channel structure. According to the map, them calling "Collinsville" is the correct dispatch center and will be for the foreseeable future.

Appreciate the report, the database has been updated.

I've been able to confirm Troop use of some former District talkgroups using Broadcastify feeds and recordings, but it appears that I've exhausted that resource for now.

The primary and secondary talkgroups for the Troops have been confirmed, as have some of the ISPERN and Car-to-Car talkgroups. Hoping to see more reports for the currently unconfirmed Troop TGs around the state.

Thanks!

Drove by the former District 17 HQ yesterday in LaSalle and the signage still says "District 17 Headquarters". Guess they haven't caught up

Yes it has. Maybe the signage will be done by the end of the year?

Does anyone know what the Lincoln Ida units are? I I heard LI-2 going on/off duty on Troop 6 today, and Troop 8 yesterday? RID of 497022

Had a half dozen Troop 1 units affiliate with the old D1 car-to-car (9065) overnight on T134 (Ottawa). I'm guessing that's the new Troop 1 car-to-car

Seems to be the pattern. The lower Districts Car-to-Car and ISPERN become the primary for the Troops, except for Troop 3.

Something interesting yesterday. Started seeing "key-ups/dead carriers" as if an emergency button is being pushed across Troop 3 talkgroups. Shortly afterward, Troops 1,2,4,5,10 all started affiliating with the DuPage and Cook Simulcast sites and started seeing the same "dead carriers". This morning, Troops 1,2,3,4,5 are all affiliating with those sites. Related...no idea, but interesting...very interesting.

No sign of a new Troop map on ISP's own website, just one showing the Districts ISP District Map .

Hard to find good help, I guess.....

ISP has begun to update/combine their Facebook pages for districts, although they are not giving specific information on Troops
