Sounds like the Pomona ICIS site had its cutover and is full P25 from my sources.
Its too far for me to catch, but if anyone can check it out and submit the new site info to the Db that be appreciated.
I presume the talkgroups numbering also changed to using the 4-digit Dec numbering.

The database has been updated with the new Pomona subsystem and the Pomona PD talkgroups. I confirmed the new site parameters today.
On a side note, I noticed Unitrunker is listing 1-16 as a peer. Can someone verify whether the Beverly Hills subsystem is using a RFSS of 1 rather than 0?

For the longest time all they had was a "console" patch to the ICIS talkgroup from their conventional analog VHF frequency. (The ICIS radio they had doing the patching was a mobile radio rather than a console.) When in the process of migrating to their new P25 UHF frequency a few weeks ago they were fully using the ICIS talkgroup. After they moved to their new conventional frequency they stopped using the ICIS talkgroup, which has not been patched to the new frequency. I don't know what their plans for the ICIS talkgroup are, but at this point it's not being used.
does anyone have the proper custom trunking table for Pomona ICIS? I am picking up about 95% of their traffic on the new P25.

What model scanner are you using?
pro-106. I'm picking up most the traffic, but I think I need some minor tweaks to make it fully operable.

Just run Pro96com software and the program will sniff the control channel and give you the custom tables for the Pomona site. A lot of us are not within range of the CC to sniff it for you. Good Luck

I have the band plan, but since this is a P25 system, you don't need it for the Pro-106. Just program the system as P25 AUTO. I have the PSR-500 which is non-Radio Shack version of the Pro-106, and it works just fine programmed as P25 AUTO.
The only scanner that needs the band plan for P25 UHF is the Pro-96. The settings in this link work for the Pomona subsystem as well as the Pasadena subsystem.
ok, that is how I have it programmed right now (in P25 AUTO). I seem to be missing transmissions as well as it coming in very gargly at times. is there any way to improve the quality a little more?

If it's not poor signal strength, then it may be due to the use of CQPSK (or LSM) modulation. It's pretty well documented on these forums that no scanner does well with decoding CQPSK. It's much worse when two or more simulcast transmitters have close to the same signal strength at your location.

I heard the CalPoly 37840 TG pop up twice on the Glendale site. Maybe they are indeed hanging onto it?

I attended Cal Poly Pomona from 1998 to 2003, so they weren't on ICIS at the time. I'm curious if the P25 UHF conventional frequency is for the parking/traffic units (T units on the radio, ex "T 12") and the community service officers (CSO units, ex "CSO 2"). The actual police units are usually Paul and Sam units. I believe the police chief is "Charles 1". What kind of units are being heard on the conventional frequency and the ICIS talkgroup?
Did they get rid of their facilities management repeater on 153.635 CTCSS 173.8 with an input of 160.11? Also, the dorms had a repeater on 463.8125 with a DCS 174 and the University Village apartments had a repeater on 464.775 with a CTCSS 156.7. The input to their 153.74 repeater was 155.685, which was the output for Lake Havasu PD. Sometimes, Lake Havasu PD would make it onto the repeater and people would wonder who they were and ask them to 10-9.
Pomona is coming in just fine on my Pro-106 while in P25 AUTO. Another thing... I was never able to monitor Pomona from Montebello, until they converted to P25. I am now able to pick them up off Montebello's cell, off their old 37680 TG (never done before). Pomona actually sounds better off of Montebello's site than they do off their own.
Before Pomona PD joined ICIS, they were on VHF-Hi with just base and mobiles. They never had a repeater set up, so you had to be in the area to pick them up. I was surprised they skipped getting a repeater and went P25, with encryption on Orange and Brown now.
Cal Poly Pomona PD was initially just base and mobiles too. Dispatch couldn't copy units when they were at the horse stables so a repeater was eventually set up. Now they're on ICIS too.

Not sure when Montebello will convert...the last meeting notes I read said they need $3 million to do it.

You Member, Member!
I pickup 37680 36752 38288 38128 just fine from West SF Valley.

Hmm, that's interesting. I ran Unitrunker on the Pomona subsystem for several hours yesterday and didn't get a single voice call hit from the Cal Poly talkgroup. They usually have at least a few transmissions every hour, even on a Sunday. However, I wasn't monitoring their conventional UHF channel during that time. I'll listen to both tonight to see if anything has changed.
I was a student there as recently as 2011. Throughout my years there they always had the Parking and Transportation Services parking officers, Police Department, and CSOs from both departments all on the same primary dispatch channel, which was conventional analog VHF-high. I really had no interest in hearing all the parking enforcement and CSO activity, which comprised 70-80% of the voice traffic on their channel. I often wished they would separate the different functions to different channels like many other CSUs and UCs do.
Around the summer of 2009 they started patching their VHF channel to the ICIS talkgroup through a mobile radio that I assume was installed in the (then) new dispatch center. Some of the police vehicles also had ICIS mobiles, but they were usually tuned to the Pomona PD dispatch channel and weren't used for communications with their own dispatcher.
It appears that with the narrowbanding requirement they decided to move to UHF and P25 rather than just narrowband their existing VHF channel.

I saw that the database was updated for ICIS and Pasadena has a police access talkgroup 2484.
What is this talkgroup all about now? I know Pasadena PD has put up a big stink about being encrypted so I was just wondering why there is another digital talkgroup in the clear from them.
