Thanks for that.

Looks like a cool project. Id give it a go myself just for the experience of building one. Not that I know how to use a solderer though. It would probably be quite challenging for me. Id buy their boards if they're still selling them tho and give it a try.
 
Copy and pasted this for you:



Banned in 1997
The Federal Communications Commission (FCC) banned the sale and use of radar jammers in December of 1997.

At the time an FCC spokesman said "the action sends a clear message to all manufactures that the FCC will strictly enforce its rules to prevent harmful interference to police radar.

If You Are Caught - It's Gonna' Cost Ya'!
This law covers both active and passive radar jammers.

If the FCC finds that you willfully and repeatedly interfere with radio signals by using a radar jammer, you could pay as much as $11,000 for each violation (up to a total of $75,000) and/or you could be sent to jail.
 
Yes, lots of FCC police patrolling the land. :rolleyes:
 
P.S. Laser Jammers do not currently fall under this federal law because laser is regulated by the FDA and not the FCC. However, some states have local laws that prohibit the use of laser jamming equipment as well.
 
I was asking I cop I know about laser jammers as I have a k-40 installed with laser diffusers in front and rear of car. He informed me that here in NJ, which is not listed on any of the radar sites as being such a state, it would be considered obstruction of justice.:eek: :eek: :eek:
 
Are you guys planning on putting signs on the roof in 1 ft. letters telling the world you are running a radar or laser jammer? Even if you get pulled over they would have to see them & recognize what they were to even think about nailing you for something.

That's why he's a cop and not a lawyer... never ask a cop a legal question, they can only enforce the law not interpret it!

If they shoot your car and get a funky or no reading then hit the car behind you and it works,then you again with same result......you're busted.
 
I thought you were talking about this.

The plans in the above link will allow you to "broadcast" the speed at which you want to read on the cops radar gun. You want 55mph? set it to that. 45, 70, 200 mph to make a google video, you can set those too.

The plans also allow you to use it in conjunction with a radar detector such that until the detector is active, the jammer is not broadcasting.

So the idea is that you set it to say 55mph. When your detector goes off, you slow to 55mph and if the officer painted you at a faster speed, all he sees is 55mph, which you're slowing down to in the meantime. I think the jammer will broadcast for 8 second intervals, so slow down by the time it turns off.

It doesnt appear to prevent radar lock. It seems to allow you to dictate the speed on the X, or K gun display.

I doubt the inability to lock in your speed fulfills the burden of proof that you are jamming them.

I agree with this 100% - I am sure the nice police officer would simply stop you for his speed observations and then mention he got a funky signal and hope you, the driver, just sort of made the "spontanious statement" "oh.... I have a jammer" and then you are busted. The best cousr of action is to say nothing and just hand over your driver's license and registration and not make any incriminating statements at all, ever.
 
I always thought that if someone built a module that will hack into the brake lights; i mean when your jammer detected the signal, the brake light doesn't work for that short period of time, (while you are slamming your brakes)... it will be safer.

Years ago when I acquired the escourt system, the rep told me that the whole idea is to slow down as quick as possible and then turn the whole system off. That way, the cop will get your actual speed after he gets the error on first tag. (The whole idea is to make the officer thinking he got an electronic hiccup on his gun, or his shaky hand on his first try, but then he gets a actual reading the second or third time he tagged you.)

You know, detector and jammer is not a free pass. Imagine a cop see this yellow nsx almost everyday traveling faster than other cars yet he only gets the 55mph readings all the time, it will be suspecious. Remember the dude use some sort of device controling the red light to green light everyday?? If you do it long enough, you will get caught.

Are you serious? All they need is the crazy signal on their gun, they pull you over, write you a ticket for jamming, then you have to prove you were not jamming. Which you can't do. The burden of proof sounds good on TV but this is the real world.


HALON system switched on. :smile:

Yes. I have the escort SRX in one of my vehicles. The SRX is a radar detector with a laser jammer. The system comes with a remote button, mine is mounted under the steering wheel, when the detector goes off adjust speed and tap the button. The officer shoots the car again and gets the adjusted speed. SO...if you are going 100mph you can get the speed down to 84 mph before he shoots you a second time.:rolleyes: :mad: :frown: :biggrin:
 
I would not reccomend those design plans.. they have been floating around forever on the various jammer forums. I used to spend hours in front of a white board learning about wavelengths and circuit theory from Jared owner of Lidatek, and I can assure anyone the concepts and design of these types of devices isn't easy.

Actually, to the original post, the only working effective radar jammer known to not be total BS was and always has been the scorpion xp. However, even the last revision of that unit had many issues. The most significant being-

1) Coverage- It was limited to analog and most new units from Kustom and other companies are now digital so the most ideal scenario for coverage on that unit was back road jaunts whereas a local sheriff was using a way out-dated first generation unit. It proclaimed coverage for X and K including instant-on in reality it only covered a subset of the available frequencies so it was touch and go as to what guns were covered. It did not do well with the original SML tests but later managed to fair better per their report.

2) Reliability- a lot of units had problems as they became uncalibrated or outright stopped working. The original design was re-sold and extended on and there was a fair amount of history there I won't bore everyone with. It was not at all uncommon for them to get sent back, and the company has never had a great track record for happy customers. Some of that blame likely falls to users with unrealistic expectations, as many would take them down to the local fixed speed radar sign and wonder why they didn't work as they didn't have a grasp on all the specific technical issues.

3) Cost- The units tend to be expensive being an enthusiast niche, with their newest KA Ultimate being about $1500 and last generation XP at about $600. Some of the participants from Gumball sported them, and could fill you in more if you are interested I know a few participants. In practice, I think the V1 coupled with good decisions is more than adequate for the more prevelant forward facing always on radar.

Remember, any expensive electronic device is worthless having a value of exactly zero dollars when it breaks and you don't have service, or if it flat out just doesn't work well. Many manufacturers in this space seem to come and go in relatively short periods, like Lidatek which recently went Bankrupt a few months ago despite having an awesome product.
 
Its just a basic Reciever Xmitter. A very (I mean VERY)Watered down version of what we have on the B52 bomber. It recieves a signal it xmits its own signal at the same frequency out and the cop picks it up. problem I heard with earlier models was the Range was terrible, I assume that was due to the power required to power the Xmitter. As far as picking ur speed u want to show up on the Cops radar was controled by adjustable resistor. If you didn't keep it calibrated it could work against u.

What happened to Lidatek...why go bankrupt...seemed like good product!!

Apparently Jared's European finance fell through. I'm not clear on all the details myself. I was shocked to find an eviction notice posted and everyone MIA several months back. I've been trying to snag a contact to get some LE10 spares, so far no go. I used to assist in the software tech support and field test departments from time to time. :cool:
