Dallas Fire - Trunked System Rollout 2022

[hiegtx]

Have y'all been picking up TG32021 (Station Radio)? I have trouble picking up layer 2 and was wondering if it was active. The VHF station radio channel just stopped working.

I'm still hearing the station dispatch, 32021, mostly on Layer 1. But the Uhf channel, 460.575, is also still in operation. Last transmission logged was less than 30 minutes ago, But it's on my SDS200, with a number of agencies programmed, so it's not likely I'll get each & every dispatch.

No, it's back off again.

I was in Dallas Friday night and yesterday. Layer 2 seemed to be carrying all the DPD Patrol Zones patched. I was staying in the park cites and signal was loud and clear.

I don't see any site locations for layer 1 sites anywhere on the FCC database ?
I only see locations for layer 2
Not sure why ?

It's may be using state licenses.

NTIRN Dallas is State licensed for the 700, it's simulcasted from all 6 or 7 existing DPD tower sites. Apparently there is a frequency shortage in N. Texas in 7/800 and Dallas couldn't obtain the requested frequencies so the State offered up theirs. I was told Collin also uses a few of these as well.

Heard DPD Northwest all day Saturday on the 700 but no other DPD. DFR seems to be more shifted over. They toned out a Structure Fire Saturday afternoon by voice with that really low rumbler sounding tone. Is the AI dispatch just not online yet?

Not sure what’s going on with AI dispatch. It’s been on and off. I’d pick it up once a day for only like 5 minutes a time

Obviously, the migration has been challenging...I'm hoping someone like the RR poster who provided the DPD/DFR TGs can share some insight on the progress - good or bad.

I've seen small departments(with say 3 stations) take months to get automated station alerting working, so I imagine trying to get 50+ stations working along with migrating to new radios is challenging. They'll get it all working eventually. I imagine we'll continue to hear periods when they're testing it, and then turning it back off for some time to come.

I don't care if they ever get it going. I usually have to Avoid it. Otherwise it's all you hear. And it is annoying.

There was some activity on 35103 and 36001. 35103 has had frequent activity during the past couple of weeks. It was no discernible conversations on 36001.

35103 is Dallas SO Wade Juvenile Justice Center.
36001 is likely Southwest Regional Fire Dispatch 1.(Cedar Hill, Desoto, Duncanville).

 

[IAmSixNine]

Agreed 36001 is likely SW regional fire disp. Also heard PD on 36003 sent to HWY 67 and Main st. which maps to Duncanville.
Seeing ENC on 36005

Sounds like Southwest Rigional Dispatch has made the switch. 36008, 36009, 36010, 36011, and 36012 are like SWR Fire Ops 1 through 5. I believe 36002 is SWR EOC.

I'm seeing something a bit odd and unexpected on the SWRCC Fire Dispatch TGID 36001. Looking at my logs & reviewing recordings, it appears to be about 50-50 between using Dallas Layer 1 & Dallas Layer 2. Also, when it comes across on Layer 1, its P25 Phase I (which would be Mode D in the database). But when the transmission is captured instead on Dallas Layer 2, it is P25 Phase II.

TGID 36003, SWRCC Police Dispatch, is primarily using Dallas Layer 2, but there are a number of transmissions coming cross as being on Layer 1. But all the one's I've seen in a quick scan of the hits are showing to be using P25 Phase II.

DFR is still straddling between Layers 1 & 2. I presume, once all the kinks & "teething troubles" re worked out, and all agencies are fully moved over to NTIRN, that these will shake out to using the same later, instead of alternating between the two, as well as consistently using the same format (P25 Phase II) for all transmissions.

Interesting. I just reviewed some recordings of 36001 and see the Phase 1 (Layer 1) Phase 2 (Layer 2) that you mentioned, but I did hear the same transmissions on both layers. I guess if someone is monitoring with a radio that is only capable of Phase 1, that the system is probably reverting to Phase 1 to provide coverage for that radio. I've seen that before on some of the Arlington fire channels.

Also, Fire Ops 6-8 are 36013, 36014, and 36015 respectively.

Seeing the update in the database for Southwest Regional., wouldn't it be its own department/agency rather than a continuation of Lancaster?

 

[Russell]

We're gonna group them together as Dallas County Municipalities for now. Then break them out, if necessary, after things settle down a bit. We still have quite a bit to learn.

If you notice the

If you notice the sub heading for Lancaster its not Lancaster, Its

Dallas County Municipalities​

So adding SWR to it makes sense.
