Does anyone know who belongs to TG# 12359 ?
Thanks in advance for your time & info... Craig

This would be TG 12352 (ISP-13-DISP) with the multiselect status bit set (see Motorola Type II - Wikipedia, the free encyclopedia). This is done if a dispatcher needs something broadcast on multiple channels (I think)

12336 is ISP Lowell Dist 13( Multiselect) according to the Safe-t DataBase on The RR dataBase.12352 is ISP Lowell Dist 13 Dispatch.

Thanks but I guess I'm missing something here. No mention above of TG# 12359. I do hear traffic on it but yet to determine who it is. Are you saying this would be a simulcast TG? I do believe it's D13 but what capacity? i.e. channel #2, a tac channel, etc. Thanks again... Craig
In Motorola Type II Smartnet trunking, the base talkgroup number is always evenly divisible by 16. That leaves 16 "bits" to be used to indicate that special features have been activated for that talkgroup. These are called status bits. You can read about status bits in the RadioReference Wiki here:
Motorola Type II Smartnet - The RadioReference Wiki
So, if your scanner is showing talkgroup number 12359, you have to divide that number by 16. The result is 772 with 7 left over. Multiply 772 by 16 to get 12352. That's the base talkgroup number. On Project SAFE-T, TG 12352 is ISP-13-DISP. The 7 that was leftover is the status bit indicating that Multi-Select was enabled for that call. Multi-Select is an ad-hoc patch that is set up by the dispatcher from their console so they can put out a call over multiple talkgroups simultaneously.
Talkgroup number 12336 is the ISP-13-ATG. This is a Multi-Group talkgroup which either the dispatcher or the user can select to send a call out to all of the talkgroups that are associated with that Multi-Group. The Multi-Group associations are pre-programmed by the system administrator.

Okay but I have been getting TG# 12352 all along on the scanner and tagged it as ISP-13-Disp. So then TG# 12359 is the same?
Yes.
Which scanner are you using?
Which scanner are you using?
Scanner: BC796D (Also have a BC296D)
See page 48 in your manual for instructions on how to toggle the status bit on and off. With the toggle ON, the scanner will ignore status bits and round the talkgroup number down to the next multiple of 16. With the toggle OFF, the scanner will show you the talkgroup number plus the status bits. It sounds like you have the toggle set to OFF.
Thanks, I much appreciate your help. I do know my scanner in & out
and know how to turn the status bits on or off. This is the very first time
I have had this issue. In 'Freescan' programming software the status bits
function is recommended off. So I have left it off in the 796D & 269D
as well with no problems (up until now)? I will try your recommendation
and see what happens. Thanks again... Craig

IF you have a question about a talkgoup please feel free to look at the RR data base for Safe-t there you will find all the "Valid Talkgroups being used by authorized users of the system" that are being used across the entire state.

Craig - it's not really an "issue" but a "preference." For example, I listen to a system where I didn't want to hear the police unless they had an emergency. So I could add the emergency status bit to the talkgroup number, program it in, set status bit off, and never hear a thing unless they press their emergency button.
The "downside" is that if I want to listen to talkgroup #16 no matter what, and I'm in scan mode vs search, I have to program in 17 18 19 20 etc. So it depends on your desires. But in the end - they are all TG #16.
W9NES means well but he really doesn't know much about trunking systems, so don't let his posts confuse you.

Rdale, I do know about trunking systems just as much as you do.So if you are in question please feel free to look at the RR data base for "Active Talkgroups for Active users of the system across the State Of Indiana" All of the active talkgroups are listed there that are in use across 92 Couties in Indaina.Tim DeLong W9NES/GMRS KAF3207/*Monitoring all of Metro Indianapolis/Marion County and Central Indiana and the World from "The Northwest Communications Center"

I think the replies by USSWOOD and RXR would indicate otherwise, since you were incorrect with your entire post about status bits. Doesn't make you a bad person, you just aren't as familiar as others with trunked systems.

If I have any DOUBTS about talkgroups I will use the RR database and the database gives my the Correct talkgroups for Safe-t.My posting on the ISP Lowell Dist 13 Talkgroups was Direct from the RR database.If the talkgroup is Not listed in the Database it is not a Correct Talkgroup.Yes I know about status bits and Tunked Systems.New people to this post do not know about the status bit indicator to the "ON" position.All of my Digital Scanners do have the status bit in the "On" position all the time and I do not "Worry" about it.

Tim, to be fair; you do not, and have never, understood status bits or you would stop posting/submitting them as new talkgroups when you see them on your scanner. No matter how many times we try to help you, you apparently refuse to take the help. I know over the last 4 or 5 years I myself have attempted to help you understand them many times.
You are confusing the ATG talkgroups with status bits. They are *not* the same thing. The statement "If the talkgroup is Not listed in the Database it is not a Correct Talkgroup" is not correct. The DB does not have every single valid SAFE-T talkgroup. I'm sure we are missing some.
Rob was not off base advising that member to not be confused by your post, nor do I think Rob was intending to insult you

The articles I have read indicate that there are 65536 unique TGs in the Motorola trunking protocol. The TGs that we see are virtual TGs in that they contain 16 real Tgs each. So if an emergency button is pressed on virtual TG 16, that tranmittion is sent on real TG 18. Its the receivers that bunch 16 TGs into one. The phrase "status bits" is Moto smoke&mirrors.
