I have been around UCLA for several hours the past weekend, and on the same exact system that I have been able to monitor them for years, the UCLA PD, UCLA EMS, and UCLA FD channels are silent. I tried searching for talkgroups instead of scanning the known TGIDs, and I do hear traffic, but mostly from parking services, maintenance, etc... Anyone have any insight what (if anything) has changed?
UCLA PD/FD/EMS

They are over on LA-RICS now

Wow, thanks for the quick response. I appreciate it! Except that its all encrypted :-(
Sort-of. Does anyone know how exactly the "De" for most of the TGs was determined? Can/do the subscribers actually switch Ø?
UCFD, EMS and CSO's have been in the clear
Great thanks!
Do you by chance happen to know which Site covers UCLA, or do they have their own antenna on campus?They are over on LA-RICS now

Downtown 700 mainly.

UCLA has an LARICS site on the roof of the Factor building and it's linked into the rest of the system. So they can do anywhere in the County on it.
Where do the "talkgroup category location details" come from? Is there actual geofencing or is someone monitoring which talkgroups are heard from which sites or ...?They are over on LA-RICS now

There's no geofencing. If you are monitoring those talk groups AND you are logged into the system you should hear them anywhere system wide. If you are outside the Factor site coverage the talk groups won't be active unless there's a radio on the system that identifies in the area. So when a unit goes from UCLA downtown for prisoner transport it would activate those sites, otherwise it won't.
I'm retired now, but I was a Sergeant at UCPD and was heavily involved in the radio systems there. I started the process of the transition to LARICS, but unfortunately the UCLA lawyers got involved and it took much longer than expected. It's operational now but I haven't had a chance to talk to any of the officers to see how they like it. Last I heard they had great coverage on the system but penetration into certain buildings and parking structures was sketchy. On the old system we had BDA's that handled that but I'm not sure if they were able to retune them for the LARICS system or not.

I was questioning that specific link, which seems to show a 0.6 mi radius circle of coverage for talkgroups 4221-4254.

I doubt it's THAT small. Our older 800 MHz trunked system had its antennas in the same spot on the same building it covered most of West Los Angeles. We didn't lose our system till we got into downtown. I would expect something similar unless they intentionally lowered the output power to keep the footprint small. I really wish I could tell you more, but since I retired, I just haven't been involved with that system. I can tell you; UCLA is one of the densest areas in the city with more than 80,000 people and more than 150 buildings crammed into 419 acres. They have more parking spaces than LAX, mostly underground and the newer buildings all have solar resistant glass, making it a chore to get radio inside. We had to install a LOT of BDA's to make the old 800 system work.
Thank you... I searched the database for the site info but did not see it listed anywhere (the frequencies to program in). I did hear them off of the Downtown LA Simulcast site listed in the RR Database.
UCLA is heard consistently on Downtown Simulcast. The site at factor is part of the Downtown Simulcast cell as far as I am aware.
That makes sense...thank you!
From the Radioreference DB Handbook:
Kinda guesswork on the part of admins.
If you know one to be wrong, send a database submission and the local admins will fix it.
