Frequency religious wars are so last decade 
BTW I saw a couple of 47 Mhz freqs in the mix as well on that NAPCO document.

You wrote: "California has a very vast terrain. Low band is a good solution to traverse that terrain with the fewest number of repeaters/transmitters."
So what were you saying low band is a good solution for?
You then went on with some comments about why things are the way they are. Perhaps there is a lot of history behind why things are the way they are, yet you were the one summing things up under the umbrella of ignorant powers-that-be.
Your initial statement about low band working and then calling powers-that-be ignorant makes no sense to me. With your conflicting statements, I'm really lost as to whether you think CHP is in a good spot with low band or not.
For the last time ...
You are misinterpreting what I write. And like I already told you -- and how the moderator warned -- this is off-topic. Thread hijacking is not allowed. Create a new thread.
Have anything to say about the CHP applying for 44 MHz frequencies? Great, let's discuss it. Everything else needs a different thread.

Coordinated pairs cost ~ $500 each from the FCC for business band IG systems, plus the coordinator fee.
Last business system I put on the air cost about $1K in coordination/FCC filing fees.
I have no idea if public safety is exempt, or if they pay APCO a coordination fee.

Falling way over the edge of the topic, but
I don't know how the other coordinating bodies handle it, like IMSA for fire, AASHTO for highway agencies, and FCCA for forestry frequencies, but I believe the local APCO chapters, who handle the police radio service, charge nothing for the initial frequency coordination work, which is the buk of the work, in their areas, like CPRA in Southern California and NAPCO for the central and north state. It then goes to APCO headquarters for filing with the FCC. There is a schedule of APCO's headquarters fees at fees
The way I understand it, the FCC does not charge fees for and governmental agencies' (and perhaps a few other niche organizations) license applications, modifications, and the like. Of course we're talking only about state and local governments, as federal and military agencies' frequencies aren't handled by the FCC but by the NTIA and IRAC.

New CHP Freq Plan

Thanks for the information. One final question before we probably should pull this into another thread.
What is the 'feedback' mechanism that helps preserve spectrum? A fee can help ensure that licensees don't preallocate frequencies that they may never use.
How does the FCC prevent local governments from reserving more spectrum than they are actually going to use?

Once the FCC issues a license the licensee has one year (or longer with an extended implementation attachment) to construct or put the frequencies on the air. The licensee then certifies with an application called a Required Notification. As with all filings to the FCC it's certified to the following;
WILLFUL FALSE STATEMENTS MADE ON THIS FORM OR ANY ATTACHMENTS ARE PUNISHABLE BY FINE AND/OR IMPRISONMENT (U.S. Code, Title 18, §1001) AND/OR REVOCATION OF ANY STATION LICENSE OR CONSTRUCTION PERMIT (U.S. Code, Title 47, §312(a)(1)), AND/OR FORFEITURE (U.S. Code, Title 47, §503).

Interesting file, I'm assuming its official info. A few questions.
1) Obviously the info at the top are current freqs with a few new ones thrown in. The bottom channels are the same identifiers but with a 2 behind the existing colors for that division.
Are these new "2" channels going to be in addition to the existing channels? A channel-2 or backup channel for every office? One that doesn't make sense to me is Golden Gate's Maroon-2. Its input is the current output of Maroon, albeit with a different tone.
2) BOR TAC is listed for every division. Are cars from all divisions often sent to assist with Mexican border ops?
3) There is a Blue2 channel listed for each division, like the office-2 freqs, every division will have a Blue-2 channel?
4) No regular Blue channel with specific division tones are listed. Is that placed into the last channel for every division layout (does not list a tone)? In the "Open List" / "End List" channel area?
Thanks.
I have some questions too.
1) What is the source of this information?
2) I don't understand what the various background colors on the spreadsheet mean. Can you fill us in on this?
3) When a number of frequencies are relabeled from the color designators to the new ones, it appears that there are quite a few with the same new designators. How are these new designators distinguished from each other?
4) Does this mean that the CHP is dropping their color designators?

The spreadsheet certainly is confusing as is. It makes more sense to completely ignore the "Old, New" row and simply interpret the columns as "Color" and "Division." For example, row 2 in the "INLAND - 801" tab has "COP1, INL"; "COP1" = Copper-1 and "INL" = Inland Division. I don't think "INL" is a new frequency name. It seems unlikely that CHP would drop their color designators.
It looks like light yellow is dispatch channels; magenta is tactical channels; purple is outside agency channels; blue is Blue, Blue-1, and (apparently) Blue-2 channels; and light orange is secondary channels (add a "-2" to dispatch channel designator unless dispatch channel is currently a "-1", in which case change to "-1A"). I have no idea why the green "Old, New" row is in there. I also have no idea why the apparent subheadings BLU, OPEN LIST, and END LIST have frequency information on the same row. And what does "BLOCK" mean, and why are only "BLU" and "BLU1" set to "N"?
Out of all channels listed, only Blue-2 and the secondary channels would be "new" channels.
All of this is utterly guesswork on my part, but it seems to make sense.

per info in http://forums.radioreference.com/ca...-forum/149464-chp-radio-system-upgrades.html
It seems the -2's will be the new channels already in the radios for when the dispatch centers and associated tower equipment can be upgraded. Some offices will go to -2 before others but all CHP cars will be ready for the upgrade by October of this year.
I'm assuming the current color freq assignments will be removed from all cars after all offices have switched to the new color freq assignments (-2) channels (2011).
Since it's apparently expected to take until ~2011 to get every vehicle, dispatch center, and radio site in the state reconfigured, I wonder if each radio will get the complete new configuration installed first time around, but possibly have an "interim" personality (for each area or division?) to use until the entire state is completed. Also, new radios coming into use in the meantime could likewise be pre-programmed for the current use as well as the final version.
It's hard to imagine that they'd want to go around the state twice (kind of like LAPD had to do in 2004 after they discovered that in digital mode, simplex and duplex don't play together well simultaneously on the dispatch frequencies).
If they did it that way they could ease into the final plan without disrupting adjacent but non-updated areas, but once everyone is ready to go, the transition to the final config could take place in virtually one fell swoop. "All units in all areas, switch your radios to Plan B" (or even an OTAR command? Nah...)

That excel sheet is a list of whats going to be reprogrammed into every control head for chp radios
but the sheet has some problems and that sheet probably wont be the final contol head load
BUT 45.32 is on the air with a 192.8 PL encoded and a courtesy tone
I havent had a chance to see what mtn it's on
i didnt get to hear it enough to see what mtn it is rebroadcasting

The way I read the pg9 of the shorter doc, all vehicles will have their radios converted between now and October 2009. That only leaves the tower sites, dispatch centers, and associated equipment which understandably takes longer than reprogramming a mobile radio.
The added advantage to doing all of the mobiles beforehand is that they can roam different areas and have coverage regardless of their own status in the transition, eg Northern units don't have to worry about not having Valley's new freqs programmed in. They'll have them before Valley's dispatch centers start switching freqs. Likewise, Valley units will also have the old Northern freqs programmed in.
Unless today's channels are kept online as backups, at some point they would want to take out the old freqs to avoid any radio channel confusion. On that same pg9, it looks like the profiles will start going away with the CPVE intro.

Spreadhseet acronyms
Most of the spreadsheet makes good sense to me. But can someone decode or confirm my guessing of the acronyms from line 1 below?
COLOR - channel name
DIV - Division
C TX - Color transmit frequency?
C REC - Color receive frequency?
S TX - ??
S REC - ??
TX CG - ?? (transmit tone)
RX CG - ?? (receive tone)
BLOCK - ?? (y/n)

It looks plausible to me, except CHP has traditionally used "C" to indicate the Car's (TX or RX) frequency, and "S" to indicate the Station's TX or RX frequency. My understanding is that to talk car-to-car they switch to "S" and transmit/recieve in simplex on the "station" freq (e.g. 42.54 if on the Green). Similar to typical repeater systems where the mobiles will talk simplex to each other on what's normally the base (or repeater) output freq.
