Howdy Folks...

Many people have known me over the years. I have literally devoted "MOST" of my free-time to the betterment of scanning society for over 15 years, relying on the scanning society in general to help me keep things updated.

I am now 39 years old and been listening to the scanner since around the age of 5 or 6, when we got our first 8 channel Bearcat IV Crystal scanner, listening to a small town area in ISP District 18, Carlinville, Macoupin County.

I work daily with the FCC Website (Applications/Modifications) to provide new information to users. (and update it to the RR DB/Wiki)

Besides CARMA Chicago, I feel I have been one of the most active in keeping things going in the state of Illinois, St Louis Region and Missouri.
I also, along side with Rich/CARMA, helped bring the STRACOM21 information online to scanning community.

RadioReference.com Forums
Illinois - Illinois Radio Discussion Forum - The RadioReference.com Forums
Metro Chicago - Chicago Metro Area Discussion - The RadioReference.com Forums

It all began in the late 1990s on http://www.ScanIllinois.com (eventually also http://www.ScanIL.com)
Later I brought in STARCOM21.com / DigitalScanning.us (and eventually www.digitalscanning.us)
(Also w9vey.net, I-warn.com, I-warn.net and many others)

Lately because of (no) funding on web hosting, I have turned off web hosting on all my websites.
Only Facebook pages and Yahoo!Groups now exist. I would like to at least have hosting for my legacy pages and a few I still update regularly

I joined RadioReference.com as an admin:

and started converting all my website information there.

I also acknowledge CARMA Chicago for much of my information, as well as continually updating them with known/updated info.
We WORK TOGTHER. Please don't deny the rest of the scanning community updates and information by not submitting updates to RadioReference.com

STARCOM21, rebanding and narrowbanding have brought a lot of changes to IL in the last 10 years. Please help!

Thanks very much for your support and continual help

I can field at least couple of these.

ISP Districts Chicago and 2 (the two I could hear from my location) don't use the HF-2 or HF-4 channels at all, at least that I've ever heard, and I used to scan them 24/7. Those 2 plus D15 do use ISPERN extensively, bases carry a PL of 67.0, never have caught a PL on a mobile. Point to Point I believe is used mainly as a PSAP to PSAP link now, I've heard both Lake County and Northwest Central calling Chicago Police on it to check warrants, but never ISP. I've never heard ISP use I-REACH either; around here it's mostly all used by Kane County. Never caught any mobile extenders, but I also haven't tried while actually out on the road.

Skipping around a bit, Fireground Red is by far the most actively used MABAS fireground around here; I think I've only heard of one other that was ever in use. ESMARN isn't used much around here since DuPage OEM stopped sending out storm alerts on it, I don't hear much of anything on it anymore other than a couple towns using it as a talkaround. I have heard key-ups and testing of some sort being done on IEMA's 45.440 repeaters, but the vast majority of their traffic is on StarCom now.

Maybe things are different elsewhere in the state, but this is what I've observed in my area. Hope this helps!

I'm not sure where else to note this, since I can't find the previous thread listing unknown Starcom21 talkgroups?

Monday evening, about 2100 hours I heard a unlisted TG 4712 with encryption not found on the RR database or Carma database.

Ashley Fire in Washington County put a new repeater online for local ops. 151.325 transmit, 159.315 receive, 71.9 CTCSS. This will be used for local ops only for a couple weeks, then their dispatch will be retransmitted on the repeater as well. Washington County and Jefferson County will still page on 154.430. It's confusing but county changes and narrowbanding made for some drastic (and fairly expensive) changes for them. And, as far as I know, all of the Washington County public service agencies are now narrowband.

Several additional talkgroups are popping up for mclean county school district 5 ,

As of this morning tg 5508 came up with more school district ops, unknown yet as to which school.
Most of their traffic has been garbled on their end.

According to an article I read there's supposed to be "30 channels", but so far I've only logged 26 of the new McLean County Unit 5 School District talkgroup, 5491 - 5516.
