Houston PD
How long has it been since you listened to Houston PD? The new radio system has a great deal of encryption being used. At present, there is a government layer for those who don't own a Phase II scanner. Even with a Phase II scanner, you will be hearing mostly dispatch channels, not talk, tactical, etc. The Investigative Operation talk groups are mostly encrypted. I don't see one talk channel for Houston. They operate on TxWarn P25.

It was before the switch over.The police seem more chatty with dispatch and other officers on the call.
Dallas police hardly like to tallk on the radio even big calls like large fight calls ,shooting ,B&E or robbery.
When I was in Dallas I never hear perimeter setup when tracking a suspect on foot wated for B&E or robbery.I neve hear victim updates info on MVA calls ,shooting or stabbing calls.
When going to hot call and person has a knife or gun in side the house
, I never hear police sergeant say do not enter the house to I get there and ask dispatch for more units.I find Dallas police hardly like to use their radio other than to dispatch calls.There is very little if any update on the call.
Well Fort Worth PD seems to like to use MDT to dispatch calls and bit more car to car traffic. There was call for guy stealing car batteries and they where very chatty about that call.But there was domestic calls , flight call , disturbance call so on and police officer was telling dispatch to send him or her the call.
The dispatch never gone verbal with these call most of the time.May be it was that dispatcher.
Dallas Police operate on conventional repeaters which gives them some functionality you don't get with trunked systems. Dallas likes to talk simplex on the repeater outputs. That's where all this chatter occurs and there is a lot of it. You just have to be in the area to hear it. It gets very interesting at times.

Yep, he is right. You find the good DPD channels they won't shut up. They do a lot by MDC though as well. If they bore you then go to DSO. Now they do everything by radio and they will drive you insane listening to them as they have more traffic that you can listen to.

Sounds like Forest Hill switched to the digital system today. Fire Dispatch seems to be 6086, PD Patrol on 6118. Also heard testing on 6120, 6128 and 6130- all on Layer 2.
FW Regional, Very Confused Listener
I understand that the FW Regional system is in the process of installation; however, I am rather confused about the FW layers 1 & 2. I see where the FWFD is under layer 2, but, I cannot figure out layer 1. I have looked in the Wiki, but find myself very confused at this point in time. I am assuming that the FCC callsigns site map is future-oriented & not complete.
When I looked at the Location Data Site Map, I am not seeing any layer 1.
I would appreciate any help.

The way I understand it layers 1 and 2 are two simulcast "sites" that are really separate systems. Each "site" appears to share the same 6 or 7 transmitter locations but with a different set of frequencies.
I haven't been able to directly monitor it or run Unitrunker on it so I don't know exactly what they are doing. The database is probably incomplete. The FCC Callsign map will show where all the transmit sites are but the RR Location map may not be accurate.

Tom is correct. On this system, Layer 1 and Layer 2 cover the same geographic area. Some agencies are on Layer 1 and some are on Layer 2. The idea is to keep it balanced and provide some sort of redundancy. However, sharing tower sites does reduce the redundancy somewhat if, for example, a tornado takes out a tower or two then it also takes out both layers and all the radio in the areas served by those towers. The system admin has the capability to push traffic to either layer with this type of set up so monitoring with a scanner can get a bit tricky. I would program the system twice, one as Layer 1 and one as Layer 2 - two systems. Then program all talkgroups into both systems.

Like GATTRS?
Thanks for the explanation. From what people have told me, GATTRS functions in this same style where they can switch layers.
At this point in time, I might just assign FW TG's to both layers in a separate loading of the TSYS. That is, TG's under layer 1 and then layer 2.

Kennedale
Did Kennedale FD and PD make the switch to digital yet and if they did does anyone have the talk groups?

Kennedale has been using the following talkgroups. Fire is dispatched by Mansfield on Mansfield Fire talkgroup 6163
6618 PD Patrol
6620 PD Patrol 2
6622 PD Talk 1
6624 PD Tac 1
6628 PD Detail 1
6636 FD Fire 1- Primary response talkgroup
6638 FD Fire 2
6640 FD Fire 3
6642 FD Fire 4
6650 Heard fire training on this talkgroup, but sounded like Mansfield

Yes, I am hearing them on Layer 2 of the FW Regional P25 system. Before the Kennedale talk groups went active, they were responding on Mansfiled Fire 6 (talkgroup 6169) but seem to be using their own now.
FWPD Zero Tolerance
Tonight, I was traveling on IH35W from DFW airport & heard FWPD in the clear on TG5015, no encryption whatsoever. In fact, I was still listening to them around the 10 mile marker on this road. I won't reveal the content of the transmissions.

Denton LE
Will Denton LE be joining the FW Regional P25 TSYS? I see that there is a site in Denton.

Denton County will be joining once they get their contract with Motorola finalized so that they can purchase all of the upgraded repeaters for their sites. The city will join but not anytime soon.

Most FWPD talkgroups are encrypted but not all. The COPS/Code Blue (neighborhood watch groups), SSI (School Security Initiative) and Special Event talkgroups are not encrypted. The COPS talkgroups switched this past week and are now active on the P25 system.
TG5015 is listed as a Zero Tolerance talkgroup but may be a Special Event talkgroup since it was not encrypted.
Tarrant County SO has already switched and seem to be using even numbered talkgroups between 5834 and 5848 on Layer 2. Other Tarrant County services such as the Jail, Constables, etc have also switched.
I also believe, and this is partially confirmed by the new posting in the DB of the FWFD backup talkgroups, that everyone on Layers 1 and 2 have backup talkgroups on the opposite layer. If primary use is on Layer 2, the backup talkgroup on Layer 1 is -1 (eg, FWFD Ch/TG 5336 primarily on Layer 2, the backup is TG 5335 on Layer 1). The opposite is true for primary users on Layer 1. Their backup talkgroup on Layer 2 is +1 (eg, Westover Hills PD/TG 5799 primarily on Layer 1 should have TG 5800 on Layer 2 as their backup. This is not true in every case- exceptions include the Interop talkgroups.
