So if anyone has some time to do some listening, here are a few TG's to look for...
31(1F)=Arrest Processing (ARREST)
207(CF)= most likely buses
273(111)=most likely CMC Helicopter dispatch
735(2DF)=most likely light rail ch 1
1201(4B1)=Sheriff Jail north main channel
I listed some as most likely as that is VERY likely to be what it is. If you look at the old system and the new P25 system many TGIDs are the same hex value. Through this pattern you can usually figure out what the TGID will be for the new system unless it is a new TG to the system.
Look at the first 5 events talkgroups:
Old ASTRO system:
656 29 MEC EVT1 EOC Mecklenburg Event 1 - EOC*
688 02b MEC EVT2 FIR Mecklenburg Event 2 - Fire*
720 02d MEC EVT3 EMS Mecklenburg Event 3 - EMS*
752 02f MEC EVT4 POL Mecklenburg Event 4 - Police*
784 31 MEC EVT5 PW1 Mecklenburg Event 5 - Public Works 1*
New P25 system:
41 29 EVT1 EOC Mecklenburg Event 1 - EOC*
43 02b EVT2 FIRE Mecklenburg Event 2 - Fire*
45 02d EVT3 EMS Mecklenburg Event 3 - EMS*
47 02f EVT4 POL Mecklenburg Event 4 - Police*
49 31 EVT5 PW1 Mecklenburg Event 5 - Public Works 1*
The quickest way to start figuring out a new TGID is to come pare it to the old system if you a full list of the old TGIDs still. Many have been removed from the old system in the database.
