I wasn't trying to insult the guy, I was talking about the book. Oh well.

 

I wasn't insulted. Are you talking about the Anarchist Cookbook? There is some legitimacy to that book. They wouldn't put anything in the book without trying it first. The same book has been collected as evidence against people because it also teaches you how to make thermite and smoke bombs that cover 5 city blocks.

[QUOTE=SgtB,Aug 5 2009, 09:46 PM] Fair enough, I missed the part where you mentioned supermarkets door openers. That's K band. To answer your question, no it still won't work. The guns shoot a specific frequency, and can be adjusted for each gun so more than one will operate without interfering. They also use coded pulses to set up the doppler reading. To block it you have to shoot back the same frequency, and enough doppler shift to jam the gun.

"schooled"?

 

*sniff sniff*


























stinks like fail in here

 

What is this statement based on? Have you or anyone actually performed any testing? It may have worked many many years ago (AC was originally published in 1971) when X was the only band in use but today you'd have to find a motion sensor that transmitted on multiple bands and across a wide range of frequencies. I can't say for certain but I'm willing to bet that these don't exist.

Not only is radar jamming illegal it's a federal offense. You don't want to mess with the feds. Even disregarding that aspect, you'll quickly find out how much "more effective" it is when your hauled off by the cops. Personally, I don't count that as effective but I guess YMMV.

As for the second half of your "more effective" statement. Do you even understand the basics of radar? Passive radars (i.e. detectors) always have greater range than active radars (like police radar). It's simple inverse square law. You can't cheat physics.

However, certainly feel free to try to beat speed traps with a motion sensor if you're so inclined. You do realize that there is also LIDAR in use out there as well, right?

For everyone else, I still recommend doing your homework and sticking with the top end units that have a proven track record. At least spend some time in the RadarDetector.net forums.

with that logic, running from the cops is an effective and cheap way of getting out of a ticket. sure it's illegal, but effective!

 

I'm just saying that you can do a lot with motion sensors. Anyone can do what they want with that information. They transmit radar pings. I doubt all the X, K, Ka frequenies can be found on the same sensor, but there are different sensors for each that you can install.

Some of you bash me because its probably illegal. But don't forget that there is a whole thread on this forum "Street Encounters" that people write about "illegal" street racing.

 

I was an MP at one point. I shot K.

I try to stay up to date with my radar gun tech. I don't have specific documents and articles bookmarked, but the guns do all run at slightly different frequencies specifically to thwart interference, and allow multiple lio's to run in the same area. I'm sure the AACB was right at some point, but speed guns are constantly developed and upgraded. Against a simple gun a blast of K could work, but most guns work right next to door openers. Newer guns require you to actively match the specific frequency and the retransmit garbage. Another issue is the power of the opener. While K band is far less focused than Ka, it still has a farther range than an opener when shot from a radar gun. There is also the issue of on time. A door opener pulses i'ts radar at a relatively slow rate. The pulse would have to be at exactly the same instant as the leo's gun. In short, it won't work.

 

you're trying to solve a problem that already has a solution ... only you're doing it in a way which is A: more illegal and B: of questionable effectiveness

hence all the negative responses
