talk groups identifing, you will decode all who show up. I am in the middle of identifying a new syste, here in st charles county, mo. St charles city was 800 digital trunking. St Peters PD was 800 analog trunking. St Charles Cty PD was vhf p25 non trunking. Two other cities were anolog vhf. They have all migrated to a system thats called SLATER. Its p25 digital trunking, and I have to copy or log everything, capture unit id's, and capture mp3 files of the transmissions. Then with the talk groups captured, we try to determine who is what and in what city. Real fun.....With the ARC 500 premium package, you can log and then make a best guess who and what they are. Not sure about WIN500 what it will log. I looked in Henderson Cty, I found only 5 systems, only one was law enforcement, the Indiana system..
