from what i understand K40 makes a laser jammer/diffuser, but does anyone make a radar jammer....that WORKS? i heard a while back about one called the scorpion that worked so well it was made illigal, but i'm wondering if there's anything close.

 

Here's a link to a radar detector forum!

http://www.radardetector.net./index.php

 

ALL jammers are 100% illegal.
Anything that interfears with police radar/lazer signals is illegal.

Not to say I wouldn't LOVE to have one, but it's not something I would publicly ask about on a high profile forum such as this

 

Believe it or not, these aren't illegal in Canada. I've got one in plain sight.

 

My understanding is that laser jammers are only illegal in three or so states. The reviews on the Blinder Laser jammer are pretty outstanding.

 

Radar jammers are illegal, it is a Federal ofense.

Laser jammers on the other hand are LEGAL in most states and Canada.

As for not publicly saying anything like that on a website like this, I really doubt that the US Federales are monitoring this site for things like that. They have bigger threats to worry about such as Irak and drugs!

 

Isn't that because the FCC doesn't control the laser frequencies and light frequencies? I had read about that once.



docb - Lucky you. You'd land in jail if you got caught with one of those in the states I guess Canada has ONE good thing going for it

 

I believe the difference is that with a laser you "catch and diffuse" the signal. With radar, in order to jam it, you must actually transmit a signal and you are not licensed to do so. Now this only addresses the FCC issues. Local cities, states, etc may have their own specific laws about detecting/jamming/diffusing (like Virginia).

 

Many moons ago I worked in a shop in Pompano Beach, FL that offered a long list of modifications of dubious nature. We referred to them as "007 Devices".
The most popular offering was hidden "safes" we would place into cars so the owners could hide their gun, cash, girlfriends numbers, etc.
For the serious driving enthusiasts, we offered "zap lights", tag changers, smoke screens and radar jammers.
The radar jammer was way illegal and was only installed into vehicles of long term customers. Basically, it consisted of a K-40 undectable, a small antenna, a **** and a digital display. This was a custom kit that was not available "off the shelf".
The jammer was tied into the front and rear sensors of the K-40. When radar was detected the jammer would "cloak" the vehicle but not make it invisible, the radar gun still got a reading. The beauty of the system was the jammer control which allowed the driver to dial in the speed that the gun would clock his vehicle. If the vehicle was traveling @ 50MPH and the jammer was set to 35MPH, that is what the gun reads.
The system did have it's limitations however. It takes a lot of energy to overcome the power of the radar gun and it's not realistic to mount a huge radar dish onto someone's car. The antenna was very small and with the energy passing through it, destruction is a real possibility. The jammer was set up to broadcast for only 5 sec at a time which was the limit for the hardware. If you were to drive through a radar trap, you had this 5 sec window to get your speed corrected.
We charged $5K for this system. The man who supplied us with the antenna and the other needed hardware was eventually arrested. The shop was raided by the DEA and shut down two years after I left.

 

Correct. Light is not really considered a radio frequency, therefore it's not covered.

Laser jammers work by diffusing the light signal to prevent a return to the source. If the source cannot get a return, it acts as if nothing is there at all. Some jammers may act by transmitting light back to the source to confuse the laser radar by giving it multiple readings... but this requires DSP as the source needs to be read, changed/confused and then re-transmitted to the source. Much harder to do on the fly, which is why the DSP is required.

Normally, these devices sit right around your license plate. That's a great (flat) surface for a laser gun to be aimed and get a return from. That's why the diffuser sits there, to try and confuse the return signal. Some have different ways of doing it, but the process is very similar.

Radar works very much the same way, really. Radar is nothing more that transmitted energy, same as laser. The difference is the wavelength. (Physics explains the electro-magnetic spectrum better than I can here...) Anyway, a radar works by transmitting a beam of energy and reading the return of that energy. It is transmitted at a certain frequency, and the changes in that frequency determine the speed of the object.

A simple analogy is a train or a semi truck. As it gets closer, the pitch of the sound gets higher. As it passes, the pitch gets lower. This is the Doppler effect... and is used in this type of radar system. (There are others, one of which measures the actual time delay from transmit to receive multiple times and compares the time difference between each one to measure speed... but that's another story.)

Bottom line: To 'fool' a radar you have to jam it or absorb/reflect it's energy. The Stealth fighter uses it's physical design to reflect the energy away from the source, while using radar absorbent material to reduce any non-reflected signal return to the source.

Radar jammers give off heavy power to overload the source, but the power requirements are huge. They are also illegal, as you need a license to be able to 'transmit' a radio frequency. Odds are, the government won't give you the license because they know what you are doing with it.

Receiving that signal is a different story. (In most states it is legal.)

Hope this helps.

p.s. It's entirely legal to talk about how this stuff works... so don't feel like you are doing anything wrong by asking questions about it.

 

Don't think for a second that the successful (and that's a serious stretch to say they work) use of one of these things will keep you from getting stopped.

 

I had two jammers about 13 years ago or so. One was great and worked. Cost about 500 I think but got stolen. Another was like around the same price, supposed to be even better. Thing was defective on arrival, just kept beeping. Took them like a year to get me a replacement and it still didn't work. They were around but were real tough to find. As I understand, these two were the only two that I ever found to really work. But they were big ugly things and you were sure to get arrested if caught with it.

 

Yup, laser is regulated by the FDA. (yes, Food and Drug Administration, not a typo )

Just for the record, you can still be pulled over and cited for "unsafe speed for conditions" (verbage varies by state) with just a visual estimation of your speed. So unless you can turn your car invisible...

 

On subject... has anyone been radar-ed lately? I think most of the departments around in and around Houston are going laser.

 

[QUOTE=DefenderC5;1561682221]Yup, laser is regulated by the FDA. (yes, Food and Drug Administration, not a typo )



I agree, but the FDA only regulates lasers that exceed .495mw of output power. The FDA requires that the owner/operator must have a current varaiance to operate any laser device that exceeds this power output. Most laser devices that are sold over the counter are below this power level.

 

ANONE HEARD OF THIS?

Years ago, someone I knew who was in the "Navy," (I believe) borrowed some material from Uncle Sam.
I was told it was "top secret" - (this is years ago)
It was like a 1/2" thick black rubber/foam sheets. It was used by the navy as a radar absorber. They glued this on items they wanted to go undetected throught radar.
When radar hit it would absorb and not bounce back.
He placed sheets of this behind the fiberglass of the front & rear of his vette.
To my knowledge, he never got a ticket, and claimed to have run into radar at high rates of speed a number of times without a ticket.
The theory is that this "absorber" gave him lots of time to slow down.

I also remember seeing an article on the same or similar material in some car magazine, with similar claims.

Its not laser proof but may be much more effective than any radar detector.

Anyone have any experience with this???

Is it available anywhere???

 

R.A.M. (radar absorbent material) I believe is rather expensive and it's makeup is top secret. The good news is that since the corvette's body is fiberglass, It should reflect a weaker radar signal than a metal object. The idea of coating a vette in RAM had crossed my mind, but with many LEOs switching to laser systems, I wouldn't bother with it.

Ideally, you'd want to drive a Caddilac Cien (the epitome of stealth cars):

anyone tried this?

Has anyone used the blinder laser jammer? I'm thinking of getting it, will it actually mount acceptable on a corvette? Was just gonna get the front only.

 

Rumor is this is the ONLY one that actually works (jams) however it's suppoed to be illigal....but then again so is speeding.

 

That radar jammer is sold out everywhere so far that I've seen.

But the laser jammer is legal. Would love to see pictures of it mounted on a vette. They say Hawaii uses all laser, Florida they say uses 50/50. I wish everywhere would go laser again. I could actually speed again
