RADAR jammers are illegal, period. I knew someone back in AZ that built his own, though, and it worked quite well. He had it tied into his radar detector and his electronic speedo readout and he could program it to read x mph slower than his actual speed, a percentage of his actual speed, or a fixed doppler offset of his actual speed. He worked for a major defense contractor in the ECM/ECCM business and was a design engineer there. This is definitely not what these commercial outfits are selling. Passive jamming is BS and simply does not work. Just give me your money instead, I will buy mods for my car.

LASER jammers on the other hand, could work if they could disrupt the pattern that the detector sends out. Lasers use time of flight as opposed to doppler shift as their means of measuring speed differential, so there has to be some kind of "tag" in the beam that allows correlation between the transmit and receive beams to distinguish specific tags to determine time of flight. The reason that the military laser designators aren't jammed is that they are significantly more powerful, and incorporate other types of signal processing to minimize any jamming. The laser detectors that the police use are much lower in power.

There is a lot more to this stuff than you are going to be able to read in Popular Science or whatever. You'll just have to believe me on this one.

 

There was something like that available at one time, but it worked by locating the signals of the mobile repeaters that the police officers wear to enable communication when they leave their vehicle. The resolution was only three miles, though, so the radius made it less useful than it could have been. With the technology that we have now, and given a setup where you could use a reasonably spaced diversity antenna setup, you could probably reduce that resolution significantly. Whether or not there is a market for that is a different question. Given enough money, just about any of this stuff is possible. Why do you think all these military systems cost so damn much?

 

For the sake of my radar detector and my hearing... please don't buy that piece of junk... I hate having to hear the Junk signal on my V1 whenever I pass one.

Valentine 1 the more the merrier... Anti-laser laser jammer (http://www.antilaser.info/)... a quality Beartracker Digital police scanner... a CB radio with good range... maybe a pair of binoculars for your passenger wouldn't be a bad idea too. Cost wise? Around 2000.

 

I would suggest a Valentine 1, a good pair of eyes, and some common sense. Think about where you would sit for enforcement. Blind hills, overpasses, tree segments on the interstate, rest areas, and onramps are all great places to hang out and run RADAR or LIDAR. Nighttime, all bets are off, especially in low traffic density areas. SC has taken to sitting one trooper w/ LIDAR on an overpass while 3 or 4 hang out down the road to actually write the tickets. A CB, as mentioned above is also a great way to listen to the chatter on where officers have been spotted. Scanners may be useful but most agencies are going to frequency skipping 800 mhz radios, making it very difficult to follow conversations. Not to mention that you kind of need to know the area for a scanner to be reasonably effective.

 

All great points by everyone. I appreciate the candor. I was confused as to whether or not these things were for real. I have a V1 and I LOVE IT!!! Combining that with common sense and a good sight, I'm doing my part to stay out of trouble.

 

Anybody have any experience with both? How about the solo2 cordless?

 

The Solo 2 is the best battery operated cordless radar detector on the market but it has limitations. No cordless detector will even come close to the performance of a top corded model like the Valentine One. Because a Solo 2 is battery operated, it goes to sleep more than half of the time which means no POP radar detection, less range, less sensitivity to instant-on radar, etc.

Check the over the hill test results at the bottom of the page to see how the Solo 2 stacked up against the others and you will see what I mean. Notice how the Valentine One beats the Solo 2 by 600-1000 feet on every frequency within the Ka radar band.

There's no cordless version of V1
It's possible to run a radar detector on two throw away AAs, but you have to give up any hope of high performance.

Performance takes power. There's no getting around the physics of it. Batteries are weak sources of power. That's why electric cars use battery packs weighing hundreds of pounds, yet few of them can top 100 miles without recharging.
Laptop computers have very expensive batteries — quite heavy, too — yet they're lucky to run two hours on a charge.
A radar detector operates like a sentry making its rounds. If the territory is small, then he can watch carefully and often. Expand the territory and he has time for only quick glances. When "superwide Ka" radar guns came on the scene a few years back, the microwave territory a radar detector has to watch was expanded more than 1000 percent, compared to the good old days of X and K bands only. Now the sentry needs powerful circuits.
"SOLO S2 uses only a fraction of the power used by conventional corded detectors," claims the maker's website.
Uh-oh, here comes the energy crisis.
The SOLO S2's "High-Efficiency Power Management" is hardly rocket surgery. It saves the two AAs by putting the sentry to sleep more than 85 percent of the time. It just switches off the power-using detector circuitry.
A sleeping sentry can't possibly give early warning when radar is used in the instant-on mode. And it gives up all hope of detecting the POP mode. Sure, a cordless detector would be convenient. And I'll be out in the lab cooking one up as soon as the laws of physics are repealed.

 

If you know anything about radar, the directional arrows, as those credit card commercials like to say, are priceless.

 

Thanks, sounds like the V1 is way to go.
