West System Transmitter Site and Takgroups.

I monitor the West System from S/E Long Beach, near the OC line. I've noticed the transmitter sites can change during broadcasts. The change in sites, and the resultant signal strength, is probably not noticeable in the west Riverside county area due to good signal saturation. Is there a primary site the West System uses or do the various sites key up randomly? What is the location of the West System sites?
I can receive through the West System all stations from Cabazon to the west. Does the Desert System ever come up on the West System?
Thanks for any info.

This is how much I know. The West System has several transimter locations as the RSO system is an areawide radio system.
The only way to hear Desert patrol cars is to either A Hope that one of the patrol cars will cross into the west area or a simulcast/patch be created, or B take your scanner to the desert area and punch in the desert system's frequencies and desired talkgroup(s).
Hope I helped you a little.

Thanks for the info. I was hoping, off chance, the Desert System was connected to the West System. Both the Central and South Systems definitely are heard at all times on the West System. BTW, I only have the West System frequencies plugged in. I haven't had any luck receiving either the South or Central systems on their respective frequencies.

I have never monitored a desert talkgroup (other than Animal Control and DA) on the West system. A desert talkgroup will briefly key up if a unit hits their Emergency button, but never carries any voice traffic.
Several years ago I used to hear Palm Desert and Indio on South when it was patched. It would not happen all of the time... usually weekends and only when patched from a certain console. I don't know if this still happens or not.
Another way to monitor the desert (from western county) is to use Santa Rosa and hope a desert unit affiliates. When affiliated to Santa Rosa it will carry the desert traffic.
Here is a chart with the systems showing how it scans and affiliates the talkgroups. I assume it's still current. West can have talkgroups from Central and South.

Thanks for the info. I haven't had any luck with Santa Rosa, likely due to distance. From my monitoring it is clear that all the western county systems are tied into the West System.

I can't get Santa Rosa here either. But when in the Murrieta/Temecula area it comes in pretty good.

No doubt Santa Rosa has a small footprint by design; insamuch as that site has the potential to cover a large area and cause interference with other parts of the system. I can receive El Centro CHP on Santa Rosa though; but that's low band for you.

When Santa Rosa was a 4 site standalone, it's coverage was intended to be pretty wide. I think it's now part of central, though, meaning it's simulcast. In that case, coverage is probably patterned and tightly controlled.

I was at lake helmet all day fri and sat. I heard no traffic but had 5 bars from santa rosa peak. Also there is a repeater right next to the lake ...anyone knows whose it is ... Looks like VHF antennas judging by the size....microwave links from Santa rosa....I think it might be an simulcast for DFG. .

That site is part of Riverside's PSEC project. It could have VHF and 700-800 MHz antennas on it.
