I have MoDot Emergency Response Truck programmed on MOSWIN TGID 21901, 21908, 21911 On SLATER TGID for MoDot is 65313 and 65228 where did you find 65012 that the OP was hearing chatter?
I had Slater on my mind when I replied. Regardless, the Modot guys call themselves Metro here for the Motorist Assist crew, not to be confused with the Metro Bus and Transit system here. When the Motorist Assist (Metro) Modot guys are patched into Slater, they will come up on any random 65xxx talkgroup on Slater. I've seen the Slater TG change every 5 minutes or less in some cases when they are roaming or patched onto Slater.
The patch seems to time out and tears itself down and is rebuilt again when they need it again but on a new random 65xxx TG.
This motorist assist group started out on Slater in their early days using TG 55313 (now unused on Slater) but have recently moved primary ops over to Moswin with a primary TG of 21911 and they are now heard on Slater only as a patch or they are roaming onto the Slater system. Either way, they are now only showing up on Slater on random TGs between 65xx1 and 65536. When they do this and you hear them on Slater on one of the random 65xxx TGs, their will often be no UID shown on radios that show that info or if you are watching the respective Slater control channel data with Pro96com or DSD+.
When I'd made the post you quoted, I'd actually heard them on the Slater system on the temp TG of 65012 even though I was replying in this Moswin thread. What I'd typed was still valid though but for the Slater system.
I see the same with other agencies allowed to roam on Slater or on Moswin in the St Louis ares. The TGs assigned are always random temp assignments in the 65xxx range which I understand is a range Motorola designated for this purpose. If the users keep the talkgroup active, then the TG usually stays the same. Once the talkgroup goes unused for some unknown amount of time, the TG seems to be released and drops, when the users come back, they are almost always assigned a different random TG.
The only constant is the fact these temp TGs will always be in the 65xxx to 65536 range. This seems to be true on both, the Moswin and the Slater systems here.
So if you hear the Metro Modot Motorist Assist gang here on the Slater system on a 65xxx talkgroup, you cannot know what talkgroup they will be heard on next. If you need to always hear them, then one should monitor the area Moswin sites and their 21911 TG which is assigned to this motorist assist group on Moswin. Or use ID Search Mode when monitoring Slater.
The use of the random 65xxx TGs makes it impossible to really give this group an entry in the RRDB for Slater because the TG is always changing.
