LWIN talk groups

Over the past two or so years I have collected the IDs and RIDs that I need some assistance in IDing
I have collected some from The Washington Parish area off the Sheridan tower and off the towers in the Northeast Corner of Louisiana, ie from Madison Parish to Richland along I 20 and from Delhi (Richland Parish) to the Oak Grove (West Carroll Parish).

The 385xxx numbers have been id to some to be maybe in the Washington Parish area. I know the 44xx series - to some in the series of number to be in the northeast corner of Louisiana.

At least that what I tower(s) I have the attached talk groups. Also in the list. Is a list of RIDs that was collected as well.

All info was collected using a Uniden 396xt and the Pro96comm software.
I am very that I could listen to more the scanner. But I was busy with family.

thanks for the help and I will zip the csv fill so that it can be used.

30164 - Heard traffic on this TG the past few days, sounds like the search for the missing 6y/o in Jefferson Parish, westbank. Couldn't hear any specific agency identity

 

[EyesofDeath]

52001 - Madison Parish SO Narc
52008 - Tallulah Police Department

 

[EyesofDeath]

need help Identifying LWIN TGRP 49084 - police activity not sure where

 

[shew]

your 49084 tg...looks like it will be in the Vernon parish tgs.....just looked it up on the data base...and saw that rosephine uses the 490??

 

[EyesofDeath]

Hard for me to think its Vernon, I'm up in Madison Parish and Vernon is like 3.5 hours away. I figure if i was picking up Vernon, I should also be picking up Alexandria. Only towers I have programed are the 6 parishes in Northeast LA.

 

[shew]

if one of the Vernon parish units is happen to be passing in ur area lets say to go pick up a prisoner at another prison....his radio will be tuned in on one of the towers u have programmed.....

Talkgroup 8556

I was listening to the South BR LWIN tower and I heard some heavy encryption on tg 8556. I searched up and down but could not find a lead to what this may be. I have never heard this tg before. If someone would maybe know, it would be greatly appreciated.

Edit: This must be a fairly new talkgroup because I am hearing it go off like crazy. I listen to BR LWIN often and I have never heard this.

This is in the Federal Agencies range of TG's.... So could be FBI, US Marshal's, DEA, DHS, FEMA, BATFE.... Literally anyone of them alphabet boys.

EDIT: Also the Orleans Parish OHSEP range..... But as far as I know Orleans Parish isn't encrypting anything. NOLA has like one encrypted PD tg, FD tg, EMS tg....

 

[Danoman]

Is there a standard talkgroup plan for P25 systems?
Or is it determined by the persons managing the specific system?

Thanks, that's what I was thinking myself since encryption around here for local agencies is to a minimal, for now.

Talk Group Planning/Layout Mapping is done by the System Administrators, usually with some input from the Vendors. These guys are usually pretty good at what they do, and have a good idea of the size of the range blocks they will need for the number of RID's to be used in each, with some wiggle room for unexpected growth. They do the research first (usually), and find out the basic needs of each agency that is going to be using the system to help plan out each block.

Example: Milf's Wide Area TRS, P25 Phase I
User's:
Milf's Butt Kickers - Dispatch, Investigations, Talk, ERT, ADMIN, Tactical, Court Security, Jail
Milf's Name Takers - Dispatch, Tactical, Special Investigations, Special Operations, Talk, UC 1, UC 2, UC 3, UC 4....
Milf's EMS - Dispatch, Tactical, MCI, ADMIN, ER 1, ER 2, ER 3, Talk, Special Operations
Milf's Public Works - Water, Streets, Power, Buildings, Code Enf., Electrical, Talk, Special
Milf's Rowdy Rangers - Parks, Lakes, Events
Milf's EMA - Dispatch, Interop Law, Interop Fire, Interop PW, Interop ALL, Ops 1, Ops 2, Ops 3, Talk
Milf's Hosers - Dispatch & Small Event Response, ADMIN, FG 1, FG 2, FG 3, Training, Outside Fire/Rescue Interop, Talk

Each of my agencies divisions will groups of unique RID's.... With primary dispatch of course having to work with ALL of the radios in each agency, and the EMA possibly dealing with EVERY radio on the whole system.

Lets take the Butt Kickers for a cross sample:

Currently I have 12 Detectives, 8 man ERT, 6 Sgt or higher, 6 Corrections Officers, 4 Bailiff's, and 75 Patrol Officers. I have planned to hire 10 more Patrol, and up to 4 more Ranking Officers. This means I need to plan for up to 212 unique RID's for Dispatch, mobiles, ht's....
SO my SysAdmin sets me up a block for these, beginning with lets say RID - 10100 for the primary dispatch console, and ending with 10212 for the final ht in the Butt Kickers ID Block. Now we assign those RID's to specific user Talk Groups. We need 8 TG's, with all of them assigned to certain ones, others only certain radios get assigned.
For the Butt Kickers lets say the TG's ID's are:
1 BK Dispatch (All 212 Radios)
3 BK Tactical (All 212 Radios)
5 BK Talk (All 212 Radios)
7 BK Investigations (26 Radios)
9 BK Administration (14 Radios)
11 BK ERT (18 Radios)
13 BK Courts (10 Radios)
15 BK Jail (14 Radios)
And lets also say all 212 get assigned to the EMA Law, and ALL Interop TG's.

All the BK is primary assigned to the 0-100 TG Block, and so forth.

Its not the fully technical explanation, for that see the wiki on trunking etc...

Delcambre now unencrypted

For now the city of Delcambre has their PD unencrypted. Their are a lot of new fire EMS etc talkgroups in ST. Landry parish. Possibly I would go to Opelousas one day just to try to identify them. I heard one on 24000 that called themselves fire district number 4.

 

[balibago]

That new Bearcat should help with this as it has a recording feature. I wonder how many they have pre sold at Scannermaster? Scanning is such a bore sometimes with all the dead periods.

Thanks for the explanation.
You seem to know a lot about talkgroup categories so I was just wondering if there was a "default" Planning/Mapping scheme that admins followed when assigning talkgroups.

Let me tell you, sometimes it is a big bore. In rural Louisiana it could be quiet for hours. Sometimes I have to check my scanner to see if it is actually on and then sometimes I forget my scanner on and I am laying in bed about to fall asleep and out of the blue it comes on. On the down times, I like to search for different transmissions and whatnot.

The only real default is in RID limitations for the overall system, and in how many RID's you can assign per Zone in wide area systems. Each individual Vendor's system may have a base default original setup, but I don't know what that would be for each particular Vendor. (Motorola's ASTRO-25 may be completely different from Harris' P25IP, and both of them nothing like an EADS, or EFJ...) The fun part is deciding how to set up your TG lineup. I have seen some assignment that start at 1 and go up to high in the 5 digit ranges, and have seen some that go ODD numbers, others that do EVEN numbering. I have only seen one or two set ups that made absolutely no sense to me, or to a lot of System Admins I know, much less scanner users lol. (Some of the AWIN assignments for example are mind boggling....)

Unknown LWIN TGs

Lots of chatter the past two days on unidentified LWIN TGs via the Hammond tower site: 35522, which appears to be law enforcement, 19505, which appears to be EMS affiliated, and 35549, which has the least amount of traffic and is possibly assigned to DOTD.

These possibly related to the icing conditions and unusually large numbers of road and bridge closures and vehicle crashes.

35549 is highway emergency services not sure about the rest
