Earlier this week, there was a wintery weather mix overnight and the folks from IDOT D1 were quite busy. I went to listen for traffic on my local yard's normal talkgroup but heard nothing. Taking a look at Pro96Com (which I had running on STARCOM21), I saw that the IDOT D1 maintenance yard TGs were being patched to one of three TGs - 33824 (North), 33813 (Central) and 33805 (South). Then, after midnight or so, they changed the setup again and these ops were only on one (33811) or possibly two different TGs (the three previous patch TGs had gone silent). A reliable source tells me that this has to do with overnight staffing levels in the comm center. At this point, I don't know if the exact TGs they patch to remains the same for each of these scenarios or not. I imagine that this process is transparent to the radio users (i.e. they continue to talk / listen like they normally would).
Bottom line - if you're looking to hear your local IDOT D1 yard operations and hear nothing on their normal TG, be prepared to do a little searching to determine which TG they've been patched to (or "cheat" using Pro96Com). Even when you find them, you might have to search again if the patching setup changes.
I have Pro96Com set up on SC21 Site 101. At the current time, the software's "Patches" tab shows that ten different IDOT D1 yard TGs are all being patched to TG 33803. If I were to run this software on the Lake County, North Cook or Will County sites I'd no doubt see more patches.
It's almost 10am on a weekday and we're not currently in the middle of a storm (or any precipitation at all, for that matter), but yet they're patching talkgroups. Again, a reliable source tells me that this all depends on staffing at the D1 comm center.
I'm monitoring Site 102, Talk group 33803 is labeled as Bishop Ford & I 57 Yard Dispatch.
Correct - but at least ten other TGs were patched to it earlier. Pro96Com shows that those patches have been removed, but at least five "south" TGs are now patched to 33811 (Harvey Yard) and at least four "central" TGs are now patched to 33824 (Woodstock Yard).
Looks to be a fairly fluid (and confusing) situation.
