I've started going to Napa a lot since my ex- moved there with my children, and I have noticed that there is NO traffic coming across the frequency identified as the Napa PD/SO primary (155.430). I have not been using a scanner, but my mobile radio, and I only had room to program in one channel, so I have not monitored the tactical channels.

My question to anyone in the Napa area: What are the channels I need to monitor to hear Napa PD and Napa County SO's primary dispatch traffic? Are the databases correct, or are they using one of the tactical repeaters as a primary? :confused:

I will take a scanner with me from now on and try to monitor ALL their frequencies, but hopefully someone can help me before my next trip. Thanks!!!!!

I'm pretty sure I heard them just the other day. I'm kinda far out but sometimes when I commute home from work I hear em. I'll try tonight.

I think 151.070 is primary.

It definitely didn't used to be! I noticed within the last few months they've started using it as the primary dispatch repeater though (151.07 - Napa SO/PD TAC RED). Then some night's they're back to 155.43 as primary (Original dispatch freq). It's bizarre. Does anyone else have any more info? Primary repeater down for maintenance perhaps? (Like what happened in Sonoma County recently.)

I programmed my scanner last night, and since I go to Napa every week, I imagine I will have some time to monitor. I will check ALL their channels and report back here with what I find out.

Thanks to everyone for their input!!!

As I said, I asked someone who works out that direction, and this is his response.

"No change in the system, just upgrading to broadcast on "Simulcast" so they don't have to manually switch the radio to the proper repeater tower depending on what part of the county they are in.
Red is usually a secondary channel and was updated first but now being used as a primary channel until the upgrade is done on the primary channel. "

I pick up Napa traffic on both 151.070 (CT131.8) and 155.430 (CT131.8) when I am listening. I will admit that there does seem to be more traffic on 151.070 though.

Ok, I was in Napa tonight, and the results are...:

They are using RED (151.070) as the county law primary. I heard no traffic on the Dispatch channel, but all kinds of traffic on RED. Also heard nothing on BLUE.

Thanks again for everyone's help and input.

I guess I didn't make my post clear enough. The person I talked to works for one of the two agencies that uses these frequencies. As my other post says, this is a temporary issue, and is due to them changing the way their system works.

The Monterey county sheriff's channel 2 repeater has been down for almost a week too. Records traffic usually herd on 158.910 mhz is now on 153.815 mhz until further notice...

Sorry about that Roln...You were perfectly clear. I was just saying that you were correct. They are using RED as a primary, and I was not disputing your friend saying it was temporary. I just know it's been that way for a month now, since I've been going down there for that long. Does he know how long the transition is going to last?

Ahh, sorry.

He didn't say how long it would last. He was a little suspicious that I was inquiring about it at all, so I don't know how much more info he'd offer up at this point.

Red (151.070) will be used as the primary dispatch frequency for the SO/PD for the indefinite future. Primary (155.430) will be used as a secondary channel. Blue (156.030) is for use by the Napa PD only due to coverage. Red is simulcast and voting, while Primary is only voting.

I designed and built the system.

Thanks for taking the time to set us straight on the new architecture of the system.

If you don't mind my asking, did you rename the channels when you designed the new system (i.e. "Napa-11," "Napa-14" etc), and if so, would you be willing to share them?

Again, thank you for time,

Inigo

Channel names stay the same. They get a little loose with using the proper names sometimes. See, it pays to put in ALL the channels for an area. The channels were numbered by the order in which they came into the old dispatch center in the 70's on the 25 pair cable. Napa 1 was Primary St. Helena, Napa 2 was Primary Atlas Pk., Napa 3 was Primary direct and so on. That is why now there is only Napa 1, 4, 10, 17. The blank spaces are from the positions they switched to directly controlling the mountain tops in the mid 80's.


I guess many more of you guys can hear us now with two stations coming up. The farther away you are, the less phase distortion you'll notice.

Anyone want to know how simulcast (controlled interference) works? I mean what technically has to happen to allow multiple transmitters to come up and not fight each other.
