CHP Database Update

[inigo88]

As alluded to by Wayne and in preparation for their changing channel assignments, I've updated the CHP section of the database so that it complies with RR database policy (Base & Mobile must be on separate lines for duplex systems), as well as making some more categorical and FCC license improvements.

I also included the area office prefix numbers in parenthesis in each channel's description - they are a valuable tool in channel identification and thus belong there. However I was wondering if knew the following area office ID prefix numbers:

- Rancho Cordova Office (Valley Division) - Should be on the BLACK.

- Oakhurst Office (Central Division) - Should be on the ORANGE.

The Commercial Inspection Facility names and ID prefix numbers were removed from the channel descriptions. Any user is welcome to add them to the CHP Wiki. We also have both Tactical and LIME Tactical channel lists that have been submitted in the past, and appear to contain much of the same information - if anyone can elaborate on this please do.

Please feel free to take a look and use this thread as an opportunity to discuss any updates or corrections (other than "the new format sucks" - it's database policy). When a consensus is reached, please "Submit" the information to the database, not to this thread.

Thanks and I hope you like it!

Just to make things even more clear, perhaps under the "Type" column you could use "B" for base channels that do not currently repeat the mobile traffic on the base frequency and "BR" for those that do. I would leave all the M channels the way you have them now. I think every other column is perfect the way it is.

rancho cordova #58 units

[markclark]

Add KBN 448 Snow Peak, to San Gorgonio Pass #97 (Banning) at 9000' + it is heard all over the L.A. Basin and beyond. Indio east of Cuckawalla Peak is Repeated. Also, Indio dispatch, from time, to time transmits to units from a radio site they call "Vidal Junction." I'm not sure if that refers to the Parker Dam site.

Can anyone confirm that Blythe #6, still patrols western Arizona from south of Lake Havasu under contract with the State of Arizona?

One of the problems is that the repeating of mobile traffic is not always a permanent thing, or is turned off when the dispatcher feels like it. And unless people tell us which freqs have the audio repeated (or are conventional repeaters) we won't know. For example, the new White 2 was repeating mobiles the other day and supposedly will in the future, but is not now.

So maybe there's a better approach to it?

Okay. It's probably fine the way it is right now. I'm so used to mobiles always being repeated in the Inland Division I forget it is done differently other places.

1) Vidal Junction is where U.S. 95 and State Route 62 meet. There is a Caltrans repeater at the site also. If I remember correctly the "site" is a tower located on the northeast side of the junction a short distance from the road. There is a small California agricultural inspection station there also.

2) The Parker Dam site is actually "Black Metal Mountain." Arizona has a site just east of the town of Parker called "Black Peak," just to make things confusing.

3) The correct spelling is "Chuckwalla." I have seen it listed as such on FCC licenses, radio system listings such a California DFG, and in ham repeater listings.

I've never heard of the CHP providing services in another state, in fact, I've never heard of a law enforcement agency providing services in another state under contract. This is not to say this arrangement does not exist, only that I've not heard of such. Even in the extreme northwest portion of Arizona where there is a short segment of I-15 within the state of Arizona, which must be accessed through Nevada on the south, and from St. George if accessed from the Colorado City/Fredonia area on the north, Arizona has highway patrol personnel assigned to it, along with Arizona DOT. When traveling through the Blythe/Quartzsite area all the traffic for that portion of Arizona State Route 95 I've heard has been from AZ DPS.

Where did you get the information about CHP providing Arizona these services? I find your report of this to be quite interesting.

Interesting.

I had another question as well - does anyone know the prefix ID number for units from the Castro Valley area office of Golden Gate Division? They would be on the Aqua with Dublin (118) and Hayward (25). (Or do they simply share one of those numbers?)

Thanks,

Inigo

The only shared juridstiction between Az and Ca is along the Colorado River. Mainly effects San Berdo County Sheriff and Mojave Co Sheriff. It's actually written into the Ca Penal Code.

I wish other CHP regions would repeat. It would make scanning them more enjoyable.

sonar what chp do you listen to ? what colors ?

I have most of the CHP frequencies programmed in for the areas I frequent, but the channel I get the most action from is turquoise, beige, copper. For the other colors, I generally hear just one side of the conversation.

Great job Inigo!!!!! It was on my to-do list, but you got right on it.

[inigo88]

Thanks!!!

Inigo, here is my 2 cents on a correction:

The Ventura office (31) in the Coastal Division is on the Purple in a traditional repeater mode with field units coming through on the base channel regularly. To my knowledge it has been this way for at least a couple of years. Anytime I pick it up, the mobile side is on there. If anyone has other info about it being selective please correct me. Otherwise I would recommend listing this one as with the BR designation as suggested.

I've seen other threads regarding the Altadena office (98) being on repeat mode at times. I have heard this also but it is only intermittent. I have heard it used from the same areas I usually only hear the base on. One possibility is that it is used in the Angeles National Forest area handled by that office. When I have heard mobile traffic it has been related to a call in that area where reception is really bad. So I would suggest keeping the designation as is for now.

The CHP # for the Castro Valley Office is #134. Typical unit #'s for I-580 are #134-580, 581, 582, and also include Mary units such as # 134-581M, 582M, etc. The Castro Valley units that have beat #'s (not I-580 units) currently range from 30 thru 70. The conventional A, B, C, D (shift) units & S (Sargent) units are still used. I believe they even have an Edward unit or two. They reside on the Aqua Channel.
