Just finally got around to posting this... while I was down in Charlotte for Memorial Day Weekend, I ran Pro96Com on the Charlotte system... it ran across a few TGIDs that hadn't yet been identified (I had it download the system info)... some of these looked to have regular traffic on them, but I didn't get a chance to go back and try to identify any of them myself (not that I'd be easily able to, since I don't know as much about the area). So if anyone has some time to do some listening, here are a few TG's to look for...

207
273
445
577
735
1201
2149

Default Charlotte Radio

Hey everyone, forgive me if this is an ignorant question

I know most of you use scanners for the area,

but I have the opportunity to buy a motorola digital radio from a friend and was wondering if I could also program it just to receive the talk groups listed in the database or if there is some sort of encryption a scanner can get around that my radio would not.

Thanks

31
207
273
445
577
735
1201
2149
31(1F)=Arrest Processing (ARREST)
207(CF)= most likely buses
273(111)=most likely CMC Helicopter dispatch
445(1BD)=JCSU
577(241)=unknown
735(2DF)=most likely light rail ch 1
1201(4B1)=Sheriff Jail north main channel
2149(865)=CATS security

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.

In regard to patching it appears there is much less consistent talkgroup patching going on for CMPD. There are some the are pretty regular but not always anymore. Divisions seem to be patching to Events 4 at times as well. Also in case it hasn't been mentioned Freedom division consists of divisions 27 ad 28. There is no patch but division 28 units work off Freedom and are the airport division.

Events 4 is the first channel in all of the CMPD zones and serves as a common channel. When large events happen it's easier to patch events 4 for units coming from outside of the division rather than have them switch zones while running emergency traffic.
