Hi,
If you are refering to Los Alamos PD, they have had an active talk group on the LANL trunked system for the past few years. It used to simulcast on 453.450 but I haven't monitored them for the last six months. Santa Fe Dispatch from State Forestry and Bandelier also have talk groups on the system that simulcast.

LAPD is now on LANL trunk. It happened about a month ago. See my web page for TG's

Yeah, they have gone from one of the most bullet proof public safety systems on the planet to a poorly maintained and configured trunking system. The old UHF repeaters are on Tesuque peak in Santa Fe. This was great because if Pajarito Mountain (where the LANL EDACS system is) was on fire and lost power (which has been known to happen), the PD could still talk. It also looked into LA's east--west canyons, so units could (for the most part) talk out of the canyon.
The LANL EDACS system is truly unimpressive. I don't think that the deviation is set the same on any of the 15 channels. It's also on Pajarito Mountain so the west end of all the canyons in Los Alamos are in the radio shadow.
One theory (not mine) on why they went that way is that the new chief at LAPD is from Florida, where they have been brainwashed into thinking that trunked=better. Why they are on a fed system is a mystery. LAFD has been on that system for years, but at least they get some DOE funding, which may or may not justify the use of a fed system.
My two cents,
Dave

Here is my unpolitical/long time resident spin on the situation.
We have a great fire department because of the Lab. They own the equipment/stations and until recent times paid the employees (now they are county employees). 80% of the calls go to the Lab. Thus Fire has been using LANL radio for quite some time.
In the aftermath of the "controlled burn" ie. Cerro Grande, the Feds felt guilt and old St. Pete helped get our town an EOC to the tunes of millions. As part of the deal...the city got a central dispatch center in the EOC. We are talking very high tech. If you do a search on google you can read about its capabilities. (I would love a tour).
So...to coordinate a central dispatch system...you gotta be on the same radio system. Thus police/fire/ems are now all on the radio system and soon....the dispatchers will sit next to each other instead of across town in different buildings.
I must disagree with Dave on the quality. I have found the LANL trunk reception/sound to be excellent, even in many canyons. On the old 453.45 there were times when they police came in scratchy/hard to read and I live in the middle of town. Now I can lay my portable down in any fashion and it picks up the trunk great.
My big fear is digital/encryption. This is probably on the horizon....PTLA and EM&R have the capability of using this now. I remember PTLA going "dark" for about 3 weeks after 9/11. I suppose the only reason they have not gone digital/encryption is the ridiculous cost of the equipment they would need to replace...thank God.
Keep my webpage bookmarked and I will try to keep you and the database up to date with the changes.

I'm just bitter

As far as the sound quality of the system goes it's a personal thing. All radio systems will vary in quality from time to time due to propagation effects in the atmosphere. Even at UHF (which both the old LAPD conventional system and the LANL trunk system are) the effects are noticable. Just listen as thunderstorms are brewing during the monsoon season (if we ever have one again, hi!).
I comment about the canyon coverage becasue I use a repeater on Pajarito Mountain (not to be confused with Pajarito Peak in the southern Jemez where Sandoval County has a comm site) for SAR in LA and it has a hard time in some of the far western end of the canyons. Rendija, Guaje, Water, Pajarito, are the most glaring examples. Not a huge problem most of the time, but I notice that Tesuque Peak repeaters (or a repeater on the golf ball on Barranca Mesa) work better in these areas.
I'm just bitter that I no longer have interoperability with LAPD
Even though NMSP has an agreement to provide SAR resources on LANL land, they won't give me a radio . I had no idea that LAPD was migrating to the system until I got a trunk tracking scanner so I could hear EMR and PTLA dispatch. It was just coincidence that they started to migrate when I got my scanner. Lucky me.
From talking with people on the inside, the reason that PTLA has not gone full time encryption is that it sounds awful. It's comming. Don't know about EMR.
Ethan -- I saw in your last message that you are a long time resident. Did you grow up here. I've lived here since I was three. LAHS '92.
You've probably seen my truck around -- red toyota tacoma with an antenna farm and SAR stickers.
Take Care

This article covers the recent move of the Los Alamos PD comm center.
Does the Los Alamos Police service all of Los Alamos County except for the DOE lands? How much land is not DOE owned in Los Alamos County?

The police cover the whole county. They have responded to criminal calls on DOE land.
I would say the county is about half Santa Fe National Forest/Bandelier National Monument, 1/4 DOE, and 1/4 private.

Hey Dave,
Are you sure about Pajarito mountain? It is an unsecured area which seems kind of risky to put a LANL communications tower on.
I thought LANL used that huge tower at TA-55 for their radio system.
Just curious...
pretty sure
I'm pretty sure that's where it is. I asked my buddy who is involved with the system and he said that's where it is. The old ten channel version might be on the tower at 55. Don't quote me on that. There is a Sprint tower and a LANL tower. You can see both from the town site. The 145.19 amateur repeater is on its own tower that you cannot see from town.
