CHP freqs:

http://radioreference.com/modules.php?name=RR&aid=995

Look under Valley Division, Sacramento Dispatch Center...Listen to freq's highlighted in GREEN. These are the base station freq's the comm center CO's transmit to the field on. Program the PL's as listed if your radio/scanner has the capability.

If you can not hear these freq's, then you either have a horrible antenna or live underground in a bunker 8) . You will NOT hear much of anything with a rubber duck on a portable radio/scanner. If you are mobile, you will need a good lowband antenna...a glass-mount or an "all-band" 18" scanner antenna won't cut it.

You can program in the mobile freqs (listed as Input), but unless you are on top of a cruiser you won't hear much. If you have a good lowband antenna, you may hear more than usual.

cool thanks for your help has a lot of 8) comedy in it but hey what ever works to get your point across

I don't listen to CHP that much, but as I recall, you can't hear the Car over the repeater output, you only hear the dispatcher?

Using: BC-785D

Try listening to the extender at 154.905. You can hear both sides of the conversation if there is an officer in the area using their portable.

yeah, but you have to be within about 2 miles or so to pick it up. It's the mobile repeater (mounted in their cars) that you're picking up at that point.

In order to listen to CHP (at least in Sac area-because mobile isn't repeated over base frequency), you need to put in both the mobile and base frequency. Occasionally you'll pick up mobile, but you should almost always hear base. It's a PITA, but hopefully they'll repeat mobile over base, like they do in the Bay Area, at some point.

CHP is as much a PITA to listen to most of the time as MHP in MS is... Lo band, non repeated for the most part......But every now and then the primary dispatch will go down, and they will switch to a Statewide Lo Band Repeater Net. Though the repeatered sites for CHP make it easy.. and I do enjoy them on skip.

Some CHP office like Marin are repeated. For some reason, they keep changing which ones are repeated and which ones aren't. The Sonoma office was repeated until a few months ago and are now back on simplex. You will have to put in both the base and mobile frequencies for the non-repeated frequencies if you want to have any hope of hearing the mobile traffic. If you have a decent roof antenna, you can hear the mobiles within about a 7 mile range on the mobile frequency and about 4 miles on the 154.905 extender frequency. With a rubber duck, you'll have to be within a mile or so to hear anything on the mobile or extender freqencies.

In the Bay area, the CHP is using the old State Police frequency of 453.825 with a PL of 127.3 that rebroadcasts at least the base stations for most of the CHP offices in the Bay area. You can also hear the mobiles on this frequency at times. Again, I have no idea what rhyme or reason some CHP offices show up on the frequency and why some also have the mobile traffic. I don't even know what use this freqency serves as you can have various staions walking over one another when there's a lot of traffic.

I live about 100 yards from a major interstate freeway, and very seldom hear anything on CHP extenders (154.905), or CalTrans in Fresno County area.

 

[LarrySC]

From the East coast we monitor CHiPS during winter. Go to www.bncantenna.com and click on Freqs then CHP with PL. The list is almost 100% except for one group of PL tones. Good Luck, Larry

CHP Freqs

I live next to a major freeway in clovis and can hear not only the mobile extender but I can pick up Hanford dispatch on Ruby, Fresno on Silver and Merced on Orange. With the amount of radio traffic I can pick up the cars about 10% of the time. I am using a radio shack pro 95 with both the rubber duck and a telescopic antena. When mobile I have a Firestik mounted on my truck.

Good Luck and happy listening

well i have a pro 94 and live about i would give it a mile from the CHP academy and i cant hear anything with the little rubber ant..... but i have this ant on my house i think its 20 feet in height and i can hear training and other stuff from over there they tried to do a test in my county with chp and west sac to talk to each other the dispacher heard the chp but the police cruiser did not hear him ....

 

[RolnCode3]

I hear CHP talking to the SO dispatchers all the time. Us listening to CHP is a different matter (SO dispatcher was asking her K9 where a CHP pursuit was, and he told her he had no idea as he could only hear one side of the conversation)...but that's not ground breaking knowledge.

I don't know if CHP around here has the City TRS plugged in or not. Never heard them. Mutual aid with the Helos is a totally different story, however. They talk to everyone, across the board.

I hear CHP around here, even on the lowband, with the RS 800 antenna on top of my Pro-96. It's really distorted, but it comes in. My BC785 with a roof mount works much better. The 154.905 is always in use around here. If you can't hear them, either they're lazy, or you are just getting a weak signal, for whatever reason. Even if they're lazy, though, the dispatcher is ALWAYS putting out "bladdha, bladdha, high speed, unable to maintain, no further, no follower, bladdha, bladdha, WRT698"

oww ya like i said i comes in perfect with my house anttenna hear all kinds of chp... from 40.000 mhz to i think 43.000mhz.. dont know where the are and also i hear training somewhere between the 38.000 mhz and up wow thats weird you can hear them i just bought the 800mhz anttenna even thow i dont hear any different then my stock anttenna but oww well.. i have the problem when its in the talkgroup saying scan id it goes to frequencies and if it just sits there scanning frequencies and the trunking is on i dont hear anything so i have to check it every so often i so hate it :evil: ...................

You would know what area's you were hearing if you looked at the RR database and entered the freq's with the matching PL's. There is really no need to search out CHP freq's since they are so well documented.

South Sac doesn't have TRS radios in any of the fleet cars I've seen...Unknown about North Sac.

 

[RolnCode3]

I know this is an old thread, but I saw a CHiPper that had an XTS3000 portable. I'll almost guarantee he had the City TRS, but I know for a fact he had the County TRS plugged in (we were talking to him on the Sheriff channels).

 

[robert_stroy]

almost dido... well about 2 weeks ago i was listening to my town west sacramento police and they did a test on the channel(13872) west sacramento police and CHP but it i guess didnt work for the chp so maybe they are going to see if they can gotr to city or county.... it would be alot better if you ask me that way everyone can talk without having to make phone calls saying they are in a chase for chp to respond and take over.......... im sure they can put sacramento chp on the county or the city look at all those tac channels that dont get used you only need for each agency 1 or 2 tac channels my city has 3 to 5 tac channels.................

A trick available in **SOME** areas to hear the mobiles when the dispatcher has the system out of manual-repeat mode is to determine whether the CHP Area Office radio system uses monitorable RF links for their various receive sites, and if so, monitor the remote receiver link.

For example, CHP in Monterey County has a bunch of 72MHz links still active.

I expect in most areas, the remote receiver site audio is fed to the regional comms center via microwave or fiber.
