New CHP Radio System

[markclark]

It looks like Indio CHP is gearing up for the new CHP radio system coming to Southern California. Two new frequencies have been licensed in the desert area; they are: 45.04Mhz and 45.18Mhz. The FCC database shows those frequencies either licensed, or pending licensing, at several mount top radio sites in the desert. Southern Division was scheduled to begin its changeover this month, but there are only a couple of the new licenses in place, so it may be the desert will get the upgrade first. Also, has anyone ever heard any traffic on 45.86Mhz ?

Which desert? SB or Riv?

Riverside County.

Definitely need to start searching 45mhz. I visit the Sacramento area every few months to visit my son. I've found that some CHP offices in that area have gone to 45mhz for the dispatch side, while the mobiles remain on 42mhz. Since many of the L.A. area office freqs are also used by other soCal offices I would guess that eventually we'll see some dispatch freqs move to 45mhz.

The entire state will be changing frequencies in the coming year. Some areas will change mobile frequencies only; such as the Border and Inland Divisions. All divisions will get a new Blue channel, and all divisions will be assigned a new PL tone. Baldwin Park and South L.A just changed to 45.02 and 39.22 Mhz respectively, with 186.2 PL. So far, it's taken about a week to get each new channel pair up and running. The new system sounds great. The power output is greater at each site and of course, the channels are repeated. I'm looking forward to hearing Indio in repeat mode.

Dang, Mark, you beat me to it. I searched 45mhz last night and found Baldwin Park in the repeater mode on 45.02. I'm too far away to hear the mobiles, and I haven't heard South L.A. yet - also probably too far away.

I've heard CHP use this as a Tactical freq as far back as 1998. It's been used as an air-to-ground for speeders on I-15 betwen V'ville and Barstow, also as a Rose Parade CP freq.

Yes 45.02 Mhz was Tac-1, Ivory and at least one other designated channel pair. You should receive the new Orange-2 much better as new antennas and coax have improved signal strength. I think the power has been increased too. It looks like they did it right this time. Channel interference isn't a consideration with the new system. I could never understand why Indio shared the Pink/Red channel with West L.A. CHP. Indio comes booming in all over the L.A. basin with its Snow Peak transmitter.

It looks like 45.04 Mhz will be the new CHP Red-2 channel for the Indio, Blythe, and San Gorgonio Pass areas. Rumor has it, installation should begin next month.
