According to information in this forum, the CHP is going to a new frequency assignments. Any idea how it's going? When is the official cutover date? Will this happen statewide, or by dispatch center?

can you provide the frequencies (and perhaps channel names) for what has been programmed? I suspect that the Excel file previosuly provided was edited at least a little. Thanks

CHP on

Has anyone came accross the new CHP talk groups?
The following is from the NAPCo news letter
http://www.napco.org/newsletters/090701nl.pdf

The California Highway Patrol (CHP) has begun a statewide initiative to upgrade communications capability for their officers.
The California Highway Patrol Enhanced Radio System, the “CHPERS” project for short, is a multi phased project that will add
7/800MHz Project 25 mobile radios to all patrol vehicles and portable radios to all field officers beginning in late 2009, with
estimated completion in late 2012
The new equipment will complement the CHP’s system wide radio enhancement effort, which will also include installation of
local 700 MHz base-station equipment at all field offices and commercial vehicle inspection facilities. The addition of the new
equipment will greatly improve the CHP’s ability to communicate during critical incidents and responses with agencies operating
on these bands throughout the state. Additionally, the CHP will begin using the 700 MHz channels acquired as the primary
band for the vehicle repeater system used to connect officers to the low band mobile radio when out of the vehicle.
Patrol vehicles will field a new package of mobile radios covering VHF low band, VHF high band, UHF and 700/800 MHz,
which will all be accessible through the vehicle repeater system.
The first rollout has begun in Sacramento County. The CHP entered into a Secondary User Agreement with the Sacramento
Regional Radio Communications System (SRRCS) allowing the new CHP portables to communicate directly with the law enforcement
and fire agencies in Sacramento County and the City of West Sacramento without a manual patch. Through an
agreement with the City of Roseville, SRRCS also added Roseville’s police talk groups to the new portables.
As part of the COPS 2007 grant, SRRCS, with the cooperation of the CHP, is adding a low band transceiver at their head in
and connecting it to an 800 MHz talk group; furthering SRRCS’s interoperability with the CHP.
At this month’s NAPCO meeting, representatives from CHP will be available to discuss their program in detail, and answer
questions that NAPCO members may have with the deployment.
Questions? Contact Lt. Evan Robinson at ERobinson@chp.ca.gov

As a secondary user they will not get their own Talk Groups, they have access to Primary User Talk Groups such as Sac Sheriff, Elk Grove PD, Citrus Heights PD, Sac PD, Folsom PD, Regional Fire etc

63920 CHPLNK is the talk group for this, only heard traffic on it a few times.

Traffic on new CHP White Sacramento channel

I just picked up some chatter which sounded like radio testing on the new WHITE BASE CHP channel - 44.920 MHz CT:173.8 :)

At the moment, no. Maybe when they finish all the sites it will be. This evening they were working on Mt Zion getting Blue 2 and White 2 working. I successfully heard both freqs with 173.8 and heard them mention 42.36 as the Mobile for Blue 2. I don't know about White 2 as what that spreadsheet lists is the Base for Modesto/Sonora.

I noticed today that Gold Valley and Black Valley were patched? together for a few hours starting around 2pm, I was getting the same traffic from dispatch on both channels. The mobiles were still talking on the correct 42.20 gold/42.70 black though. How they were not talking over each other, I have no idea.

Ultimately, what method are they planning to use across the state to auto repeat mobiles on the base? Are they sticking with the audio switch method they already use in many areas, are they going to conventional repeaters, or something else? Their new licenses do not include the typical FB and FB2 needed for repeaters.

It's probably revolving around what's already available or how it's done in the area. Based on what I've heard around here it's all still separate receive and transmit stations that relay over the M/W to Sac.

Just in the past 9 months, CHP has been taking up 800MHz in the San Luis Obispo County and Santa Barbara County looking at the FCC licenses.
