Anyone manage to determine the base frequency and offset yet?

I'll get the site in the Db once we have the information confirmed.

Pasadena site is in the DB now.

im confused about the database the tg 2101/083 red 1 patch is the same id in hex as 2096/083 public works? i spasadena sharing a tg across the systems with glendale and what would happen if a public works guy talks when the system is linked together and a fireman wants to talk?

From what I gather the new Pasadena site is essentially a stand-alone system, with other ICIS users not having the ability to roam on it. (as they are not P25 TDMA)
As such Pasadena system TGs likely are unique only to it.


Additionally for everyones information, following discussion with fellow Db Admins, we will be creating a second ICIS system in the Db, for the Pasadena and any future P25 TDMA sites.
For users that download directly from the website, we must show two separate systems, the legacy MOT Type-II, and a second P25 TDMA one in order for things to function correctly.

The Pasadena Cell is still being put together as we speak. In fact the Goodrich site isn't even online yet. The Verdugo traffic you heard is only a temporary patch at this time and won't be fully simulcasted/forced onto the Pasadena cell until it is fully up and all sites are operational.
You'll be hearing a lot of strange patches and other transmission testing going on for the next few weeks. After the system goes fully online the tech's will then try to crash it and put it through all of it's paces.That will be the fun part.
At this time there are only a couple of talk groups that are being fully simulcasted between the SmartZone and the P25 cell. Also at this time the system is FDMA mode, however it can be upgraded to TDMA in the future and can run in dual (FDMA/TDMA) mode.
From what I have seen, P25/9600 baud access time is really fast compared to 3600 baud and the audio seems to be really good too.

What is the goodrich site? Will that be site 11?
Don't know the site number, but it's north of Foothill Blvd east of the 210 overpass between San Gabriel Blvd and Sierra Madre Villa Ave.

It's immediately east of Eaton Wash and west of the Edison Company's high-tension lines. The name "Goodrich" comes from the City of Pasadena's adjacent "Goodrich-Twombly" water well.

T M Goodrich was Manager of the Pasadena Light & Power Dept in the 1950s, and the 1971 receiving station that abuts the 210 at Foothill Blvd was named after him. Fred Twombly was an early Pasadena City Councilman who pushed long and hard for creation and expansion of the city's water system, and the well got its name from those two guys..

More than anybody really cared to know.

For users that download directly from the website, we must show two separate systems, the legacy MOT Type-II, and a second P25 TDMA one in order for things to function correctly.

Before we go and make changes based upon misunderstandings, let's talk about these systems in a broad sense. There is nothing that prevents SmartZone and P25 systems from being tied together. The radios can roam, but it won’t be automatic. The user will have to change the channel. Automatic roaming only works when systems are of the same type with the same parameters. ICIS already has cells that will not auto roam with neighboring cells.

As I stated in post #538 (http://forums.radioreference.com/1515301-post538.html), what is listed in the database under “DEC” is not the decimal equivalent of the hexadecimal ID but the Trunktracker version (decimal * 16). When programmed for SmartNet/Zone systems, Trunktracker scanners use the Trunktracker ID. When programmed for P25 systems, they use the “real” decimal ID.

Using Verdugo Fire as an example, the RR database shows Red 1 on “33616 DEC” and “835 HEX.” If you take 33616 and divide it by 16, the quotient will be decimal equivalent of $835. The quotient looks familiar, doesn’t it?

When talking about P25 phase 2 (TDMA), one needs to keep this in mind: Nearly all public safety agencies have been purchasing Motorola XTS series portables and XTL series mobiles over the last few years. These radios are not capable of operating in the phase 2 mode. New radios must be purchased to make that change (APX series from Motorola, but many manufacturers make equipment). If the agency hasn’t made a large radio purchase lately, there will be no TDMA.

As I look back at the forum, I see the second database entry has been created. For ease of reading the database, there should be three columns: Trunktracker (for SmartNet/Zone), Decimal (for P25), and Hexadecimal (I never understood why. For techs programming radios?). That approach won’t work for the download function, but unless there is a good description on the P25 ICIS listing and the three column approach on the original, listing two separate systems makes people think the two are different when they are, in reality (or quite possibly, sense I’m speaking in a broad sense), the same.

Just for the record, the need for a 2nd ICIS system the Db has to do with the inability to show a mixed MOT-II and P25 modes within a single TRS system.

We have a few other examples of this in the db across the country as local entities run two technologies side by side.
Even if they are linked internally via SmartX for the frontline users, we still must show them as two different systems in the db.

Glendale PD patch has shown up on the Pasadena cell as TG 93 (Digital)

Also heard Pasadena PD would move over sometime soon utilizing full encryption.

Icis just completed a system upgrade to narrow band last night. Anyone know what they did and how to reprogram xts5000 to work?

My unitrunker shows that the Glendale, Burbank and Montebello cells are now System ID F108. Culver City appears to remain 891D.
