Are incident size-ups (and other traffic to/from dispatch) now a being done on the command channels, when one is assigned? Previously, size-ups and other traffic for structure fires etc. were done on the admin channels (eg, blue 1). But I’m not hearing those on the new dispatch channels anymore.
LA County Fire "Future Use" freqs testing
- Thread starter xilix
- Start date
i asked them on X if they were going to continue streaming, they said yes after the tweaking is done, there will be 30 freq...
OK a question from out here in the desert....
LARics is primarily a digital trunked network, soo
Will LAcoFD remain on analog conventional, or go p25?
What about trunking?

Do any of you have a combination of voice and data on some of the frequencies, for example on 482.974, D-4? Maybe it is just a lack of selectivity on my 30+ year old Pro-2006, but I am also hearing it on my Pro-96.
Exactly correct. Units not assigned a Command channel shall be on the "D" dispatch channel. All structure fires are assigned a command channel. All traffic pertaining to the incident occurs there (between the dispatcher and units on scene).

You're hearing P25 Phase II from 482.9625 MHz, which is a voice channel for the LA-RICS DTVRS West Simulcast (Site 59); the 18 kHz-bandwidth wideband NFM filters on the old scanners don't cut it anymore with LA now using 12.5 kHz channels to their fullest density.

That makes total sense, KJ6PSG. Thanks so much. I noticed I don't seem to have that problem on my older handhelds with PLs set on each LACoFD freq for some reason.
A bit off-topic for this thread, but now that LA-RICS seems to be up and running, have people with P25 Phase 2 scanners, other than the SDS series, noticed simulcast issues?
TNX and 73.

Not here in the West SFV. I receive North Simulcast UHF and 700, Magic Mtn UHF and 700, West Simulcast UHF and 700 very well. San Gabriel Simulcast UHF and 700 comes and goes depending in the wind!
BCD996P2 with a VHF-high 1/4-wave ground plane at 20 feet.
I don't listen to LA-RICS much, not a whole lot there yet.

The "Future Use" frequencies now are listed in the Db as "Countywide", and the old Countywide configuration is renamed as "Old Countywide" as frequencies are depreciated or transitioned to other uses.
Besides the old Blue-8 still being active, I have noted brief activity and key-ups on Blue-1 and Blue-3 in recent days.

On this topic, reception, I travel from Ontario to long beach, 60 frwy to the 710 to LB.
The reception if terrible, CW was worst in Montebello and Monterey Park, which I figure would be great.
Dispatch is all scratchy and barely heard, VHF tach and CMD channels were loud and clear. In fact CW Disp sounded better in Ontario than anywhere else. I'm using my SDS100 and a dual band HH antenna. When I get in to the SoBay area, its better, but not like the old Blue setup.

I'm really impressed with the audio quality and levels with the new system. I noticed that when I'm working in my home office, and just listening to the scanner, I'd forgotten that I was not listening to the Blue System. I also struck me that the audio is pure analog, without that weird Digital-to-Analog affectation that we hear from so many P25 radios that are toggled into the Analog mode.
Hats off to LA County's telecomm folks. Well done.

On the new channels, the one labeled "U-2 Admin" has been abnormally quiet since the cut-over. After today's earthquake roll-call, I can see why. "Admin" is only heard on the trunking side. I'm starting to wonder if "U-2" is just a spare channel and not actually "admin"?
I've only heard a few transmissions on U-2. Not much activity there.
They "should" be using it as the new Blue-4, or Admin. I'm guessing by the description in the FireSync app that they don't know what they want to do with it yet. ("Countywide ?")

Not hearing any dispatch traffic on LARics in the AV today.
As mentioned, all Dispatch channels along with the first up Command channels for each are up. All other commands coming soon. Maybe even LAC A/G. Working on filters to remove the key tones. Thanks to the Los Angeles County Firefighters Association for funding this huge project!
You should hear the same traffic on D-2 & D-5 24/7. Same traffic, different repeater coverage.
DPK, TPK, BJM, & two main land sites (RHT & CCB).
Yes. For All Hazards incidents, you will see the COMMAND## phantom unit ID.
Correct. The simulcasts were built for their geographic usage. LAC U-1 & U-2 are countywide.
See above quote re: feeds. 🤙🏼
U-2 is not for administrative traffic like Blue4 used to be. The ADMIN TG is for all administrative chat.
🤔 Can you explain further?

The county wide dispatch, Blue 8 was normally going out on LARICS. There was no county wide dispatch on it yesterday when I was in Lancaster and Palmdale.
Do you mean LARICS TG: 1006 (LACOFD DISP), which was patched to the old BLUE 8 (now what would be U1-Countywide Dispatch)?
