Question for CHP

[dasmi]

I was listening to the CHP in San Diego today, and someone made a felony stop. Until the officer advised he was code four, there was a tone every few seconds. When he said he was code four, the dispatcher said she was turning off the tone. What's the tone mean?

[tgriffin]

Keep the channel clear.

Might be the beeper, they sound evert 20 seconds or so to remind people to keep the air clear..

Correct me if I am wrong, just a guess..
I listen to the scanner 24/7 in my area, I like to know what is going before the cops show up.

[dasmi]

Yeah, I think it was about every 15 or 20 seconds. By the way, thanks, CHP for not going to a trunked or digital system yet, otherwise I'd have to drop money on a new scanner

They have in Norcal, I'm really suprised they don't have one in San Diego.

Where in Norcal is CHP operating a trunked or digital system?

[Glock Fan]

How do you listen to what they say on the radio? what kind of scanner do you need to buy? i live in OC. are they on a special system?

[Spyder]

Ya, pretty sure NorCal is using the same system as those chippies in SoCal. We use their system as well...but I haven't really learned much about it yet so I couldn't give you any details.

The SF bay area, everything dispatches from the Benicia center. I assumed it was a trunked system as you can not track them with a scanner. You can usually get the dispatch but not the cars unless your line of sight to them. Also the local PDs have to have calls relayed by dispatchers when working with CHP. But this is all second hand info from my dad, he's big on the scanner and ham radio stuff, I deaf enough that I don't need the frustration of trying to follow radio calls.

Tone: emergency traffic only

Code 4: Clear, no further assistance needed

Where were you listening to both sides of the CHP channels? Those are notoriously hard to hear because they require the vehicle to be nearby, and the radio/scanner to trunk to the channel dispatch is operating on.

Yeah, I can get both.

I listen to CHP in Fairfield all the time

Dispatch 42.6000 PL 131.8
Car to Station 154.9050 PL 173.8
Car to Car 154.9050 PL 156.7 (i think)

1 is generally just for the officers to talk to each other (close range), and the other used for communicating with the dispatcher. Keeps them clearer!!

What scanner setup do you use? My dad had a scanner when I was growing up and it was pretty bad-***. I remember picking up cordless phone conversations, back before they were digital.

Mines a Radio Shack Pro-162, its discontinued so you can get them new for $130 at the RS. It won't do digital but picks up tons of other stuff, the wife actually has gotten into it a little bit also.
