What bands are being used in California? I'm hearing it's just Ka for CHP and some locals are using K. Is that true?

Is anyone using X band around here or can I safely turn that off?

Lastly, my K40 RL360i allows me to turn POP on and off. Any recommendations on this one?

I'm sure all of this has been covered before. If so, please point me to it.

Click the RDGFS link at that top of the page to see what threats have been reported for your state.

There's no X being used in CA, so it's safe to turn that off.

In regards to POP, I turn it off as it speeds up the detector, and it's really not used much, if at all, these days. And, a POP speed measurement is non-evidential, so it can't be used in court. See the video made here by Vortex for the long version :).

Some people will say there is no K. A fair statement is "there is almost no k". If your concern is CHP, KA and LIDAR are your threats. There is not much k in the cities left. BUT, I just saw an older suv patrol vehicle using K last week in Benicia.
Don't worry about pop, leave it off.

Ok, so everybody agrees there is no X and I can turn that off with 100% certainty?

Without a doubt, you can turn off X band. On CHP-patrolled large freeways, 34.7 KA is your primary threat (I'd say 95%). On some other freeways with other patrolling agencies, you may see some 35.5 as well (particularly Placer County, as well as national parks).

There have been sightings of city police cars equipped with or using K band guns, including possibly modern K band guns like the Raptor RP-1, which have compact patch antennas much like a Stinger.... But that's a really really rare possibility compared to the other bands.

If you cannot trust K band alerts from your detector, you are better off turning it off. It's much more important to be able to trust your detector to the point that you take braking action before listening for a band ID or reading a frequency. That is far more likely to save you against sneaky CHP tactics versus the marginal benefit of discovering a city cop with K band.

True, if you ran K band on in CA, you risk becoming anesthetized to the neverending false alerts. You will likely NEVER see a real K band, unless you know your neighborhood cops use it in school zones or something. I asked a friend in SoCal who runs a STiR+ and he has K band turned on, but he has ran it long enough that his unit has filtered every false K in his area. He said it has been "years" since he saw his last bona-fide K alert, and he pretty much drives for a living.

guys, this is great intel and a real help. Many thanks.
Scotts Valley PD ran K band for years. Starting around 2009, they moved to Ka, including handhelds. There is a statewide contract with Stalker that all California agencies can leverage, which is why K has been disappearing. The only places where you MAY see it are smaller town PDs who don't bother updating their gear but once a decade. Someone pinged on here a few years ago that Orinda PD run K band. So if you happen to be on a surface street in Orinda, turn on K band. :)

Don't forget that Stalker does make a new K-band gun with modern digital antennas, the Stalker Patrol: http://www.stalkerradar.com/law_patrol.php

The Patrol is in fact newer than the Stalker DSR 2x that most of California standardized around, and I presume there's Stalker incentives on that too. We've heard some reports of New York departments liking the Stalker Patrol, but it's not clear whether or not it'll catch on around here. Certainly so far, nobody in CA has reported seeing a Stalker Patrol. But it just goes to show, all things change over time, and it's good to be prepared, but there's a balance to hit between prepared and paranoid.

Noooooooo.... please no new K band in California! Will have to be on lookout for that.

Can't do that anymore with BSM systems. They'll punch right through the K filter on these older RDs (STiR+, K40, Redline, etc.) and GPS won't help.

On the next episode of "Finding K-Band", the team travels to California to follow up on reports of a possible K-Band alert in Orinda.

Turned X off here in the SF Bay Area for years. Ditto for K. Just running Ka now on my V1.

Grew up in Orinda, and now I definitely don't have a reason to go back!

Hopefully, San Francisco's wishes for "automated speed enforcement" (speed cameras) won't come to fruition, especially if they use K-band. As of now, from what I know, to do so would require a change in State law.

If they ever do that, I've got a SD card in my dashcam that stores 2-4 weeks worth of data for the amount of driving I do. Because none of SF's city streets are highways with PSL of 65 mph, or undivided two-lane highways with PSL of 55 mph, maximum speed law does not apply. I'd simply challenge the ticket under the basic speed law, which says it's legal to exceed PSL as long as it was safe to do so. Burden of proof is on me to prove it was safe? Sure, I've got dashcam video, front and rear.

I'm more worried about that Stalker Patrol that jdong pointed out though. I think it may be time to get a Stinger.

My town's PD got one (only, so far...........knock wood) about a year ago. The rest of the cruisers have Stalker duals or DSR2X's. No idea how well they like it. (& I'm not going to inquire) I hate it, not just because of it being K, which is bad enough, but the alert range is much less than with the Ka guns, although adequate so far (knocking wood a second time)
