Jammers or Detectors. Which is best

[sAsLEX]

A typical jammer does so by processing the incoming signal from the targeting device, coupling it with FM static, and then reflecting it back to the targeting device.

how does one add FM static to a reflected signal without transmitting?? This is the point that confuses me.

this is what jamming is about

Each pod houses two powerful continuous wave (CW) transmitters which use beam steering to direct the jamming signal at the threat

they are only illegal if you get caught ... right?

You're only in the shit if you get caught, they are illegal regardless of whether you are caught or not.

As I understand it there are two kinds of, for want of a better word, jammers. Those that transmit and those that do not. Can you claify what kind are illegal.. The biker that I was talking too had a Rocky Mountain jammer and he swore it was not a transmitter. Would like to see the legislation (I can not find it) on this if you can post it would be helpful.

Skyryder .One of my work mate's has just got a Jammer from the USA $480 to the door of his house . Made by Rocky Mountain totally legal to use . Work's on everything . SENSEI

I think that there is some confusion here between lazer jammers and radar jammers....... which sky are you asking about?????????????

If refuring to lazer jammers........ then are they ONLY illegel to use???? legal to own, buy and of course sell.

Radar jammers I believe to be illegal reguardless..... yes/no

Rocky Mountain jammers, from what reviews and tests I've seen on the net, are utter crap. In fact I'm sure I've already posted here the link to some of the reviews in a previous thread. This is not my opinion, but that of independent testers. If anyones interested, ask and I'll try to find the links.

I'll confess to knowing stuff all about them. They are not illegal to own but you can be prosecuted for operating a device that interferes with the day to day operation of police speed detection equipment.

Again, I'm not sure of the relevant legislation / regulations etc but its no problem to track it down. I'll ask one of the snakes at my shop.

Yes I've seen them. Just not too sure how old the test results are and for what models. This guy I ran into had a Rocky Mountain and he swore by it. Even bought one for his son. The problem there so much conflictiong evidence on jammers detectors etc just no too sure which way to go. My gut tells me to get a jammer.

Well FWIW http://www.radardirect.co.nz/index3.html have tested thes jammers and only one worked every time the blinder.... RM dident get that good a write up.
Dont get ballsed up with a Yank test cos they use differant systems to NZ

You simply cannot buy a proper, 100% effective radar jammer off the shelf. The only ones that exist are ultra wide band units used by the military and they cost tens of $1000. (K & Ka frequency bands, as used in NZ and Oz, are very wide - you'd never be able to cover them all with an off the shelf bit of kit). You're confusing them with laser jammers me thinks, which do work, only because they confuse the receiver diode and Rx circuitry as you swamp it with crap (I can get technical, but I won't). You can jam a small portion of the radar guns frequencies some of the time, but not all of the frequencies all of the time. Or all of them some of the time for that matter.

Incidently active jammers are those that are powered, passive just sit there and are as useful as a snowball in a coalmine. Like Rocky Mountain shite.

Simply sending the same wavelength (frequency) back from your speeding bike WILL NOT WORK. Ok the theory here that was posted in correct, however there is something called a doppler shift which covers the fundamental physics applicable to a wavelenth originating from (or to) a moving object by changing the frequencies phase. To just cancel out the incoming frequency would take massive procesing power - again, huge expense required here.

I checked the net regarding laser/radar jammers a year or so back, and also spoke to a guy in the industry who knew a few people using them. Co-incidentally this research was done shortly after me receiving a ticket

My understanding is in simplistic terms you could buy a laser jammer, and you could buy a radar jammer. Separate units, separate technology, separate price tags. There was only one rader jammer that actually worked, and it cost somewhere around US$1000. The magazine review on it commented something along the lines of driving the truck over the radar before you'd notice it.

Laser's were in a similar boat, wide variety of results and I think only one or two really did work, and were priced accordingly. I came to the conclusion the tickets were cheaper than the jammers.

I think it went something along the lines of it was legal to use a jammer that did not transmit, but the jammers that did not transmit did not jam. Kind of pointless expenditure ya think?

I was told by my industry mate that the three people he knew who ran these units hit the picks the moment they went off, slowed down and turned the units off. Thereby allowing the radar/laser user to get a reading on them and hopefully not making them too suspicious - thereby avoiding the traffic stop and subsequent explanation of what the little black boxes were for. I seem to find that cops often don't get a lock on a bike as quick as they do on a car (or perhaps I've got fucking huge speedo error) - which would give more time to slow down.

Unless you're planning on subscribing to the dark side and avoiding the ticket through use of the throttle - in which case you need a scanner not a jammer!! But I'm not advocating that!!!!!!

[madboy]

I should also point out that I dropped out of college physics, and won't pretend to know bugger all about how the devices work. I'm just going off the net reviews and heresay of others!!!

You can't get a jammer to operate without it transmitting something. The only semi-legal (since it doesn't need to be operated to work) way I can envisage is to have a stealth vehicle which absorbs a lot of the radar and what it does reflect isn't reflected towards the reciever. And then that would cost more than a life time of tickets, so why bother?
