On a trunking system (Unless it's a Harris system), having the voice frequencies isn't necessary and shouldn't make a difference. That's what the control channel does, finds the voice frquencies based on the data stream.

Interesting.. I guess I wasn't aware of that. I'm still relatively new to scanning. (Got my first scanner up 1 year ago today). Guess maybe that doesn't answer some of the issues I've had with my SDS100, I was under the assumption they were designated per site and licensed as such.
When you program a trunking system, all that's needed is the primary and alternate control channel frequencies.
What kind of issues?
Talking quickly between dispatch and the crews is sometimes cut off. I have had to play around with some settings which seemed to have made it better but it hasn't been perfect. Seemed to happen after I did a brand new code plug, wonder if I messed up a setting in doing so but didn't realize it.
The ideal programming is the closest site(s)... control channel and alternates, site hold to 0 secs. If you downloaded from the database, you might have all the sites scanning. The information here is pretty accurate, so I just program manually via Sentinel. You could increase the talk group delay time too. Many variables to consider.
While reviewing SC21 recordings from this past Tuesday, I caught a couple of units (RIDs 189100 and 189101) performing mobile coverage testing in Willow Springs, La Grange and La Grange Park on talkgroup 34485. Police and Fire units for all three of these towns are dispatched by Lyons Township Area Communications Center (LTACC). Sounded like these might have been folks from LTACC, as there was reference to having police and fire units test indoor portable coverage in the future.

Was this on T102 you heard Lagrange Park or T101....TY
Caught Northwest Central radios doing testing on site 501, talkgroups 25300-25309, some encrypted some not. NWCDS supposedly has backup talkgroups on the county system but not sure if these are them or not. They are also one of the backup PSAPs for the county should something go wrong in Des Plaines and Maywood (the normal county backup center) not be available. I also believe that the Cook Metro West TG that is identified in Cook County's plan to bring Palos Park (this has it's own thread in the forum) in is TG 25233, but obviously I can't prove this and it's just a guess. 25150 however is without a doubt Northlake PD, that one I can confirm.
Additionally, reading through Cook County ETSB minutes, looks like Park Ridge is switching AGAIN. In the February minutes (available here) they've put their notice in to WSCDC and will be switching to Cook County in February 2021.

Off site 149 I've got a handful of IDs from 189000-189985 affiliating with that TG. I've also got them affiliating with TG 34481. Only one voice keyup from any of the radios, oddly enough on a Pace talkgroup. I'll try to keep an eye on it.
I don't recall, Ron, but I know that it was one of those two Sites.
We've been hearing both Lagrange FD (RID's 189100/189101) and Western Springs FD (RID's 189200/189201) testing today with LTACC (RID 189708) on TGID 34488 this morning from various locations throughout their villages. I heard traffic on both Cook (1-002) & DuPage (1-001) Sites.
If anyone else logs Radio ID's, specifically District-Chicago, they have updated all the patrol division's radio signatures since Friday. Supervisory personnel has updated their radio signatures within the last 2 weeks. I've been logging all the changes and hopefully will have my list completely updated soon.
Probably others have noted some new payroll disposition codes. Code 451/Community Caretaker has been broadcast frequently. In addition Code ES (Edward Sam), which stands for "Emergency Stand-By". All personnel are available for assignment 16-24 hours per day. "show me 10-42 Edward Sam, now show me 10-41 Community Caretaker". Do they have to pick up garbage and dog poop too or take little old ladies to the grocery stores?
I see why they did this. Probationary Troopers reported to their respective Districts yesterday, and portables were issued. This morning heard "the newbies" going 10-41 and used C-190 series call signs. RID's coincide with their badge numbers and I've seen upper 6900 and 7000 series.
No more C-300 series, but they will now be assigned in order? Other districts I know do the same thing, once they get assigned a call number, they keep it throughout until a promotion or reassignment. I follow all the ISP Districts on Facebook and District 21 in Ashkum posted they're welcoming 21-55 through 21-58 and had pictures of the cars.
Heard a couple other probationary troopers in the upper C-180 series with RID's 1007xxx series when they went 10-42 today.

Can't get the new rides quite yet!
Now to add confusion for all those RID taggers, Dist. 15 (Oak Brook), is assigning the probationary troopers vehicles, but they are assigned "Car 300 series" radio signatures. "Oak Brook, Car 309, show me 10-41 in Car 197, riding with Car 35"...now that's a mouthful!
Starting to hear District 2 and 5 probationary troopers doing ride alongs, and are continuing the "2-1xx and 5-1xx" radio signature pattern. So many radio ID's to tag, so little time!
Years ago, in the early 90's when ISP was switching out some of the Caprice PPVs for new Crown Vic PI's, my neighbor, a trooper with District 11, told me a story about him and an accident reconstruction investigator racing their vehicles back one night after responding to a fatality accident. My neighbor was in a new Ford, and the accident investigator was in a Caprice PPV station wagon. My neighbor said that his Ford was left in the dust by the Caprice, and that was with the total station, and tripods, and all the other junk the investigator carries in the back of the wagon.
