New Demerit + Fine System & Radar Dectectors Banned

[NZVengeance]

Now back to what this thread was about.

This is my undersanding of how radar detectors work. please let me know if anything here is incorrect

Good raar detectors work just like a simple 1 way radio they pick up a signal and make a sound for you. other radar detectors are what are called "superheterodyne" radar detectors.

The term superheterodyne refers to a method of designing and building wireless communications or broadcast equipment, particularly radio receivers in which a locally generated frequency is combined with the carrier frequency to produce a supersonic signal that is demodulated and amplified. Sometimes a receiver employing this technology is called a "superheterodyne" or "superhet."

those radar detectors can be detected because they emit a carrier wave.

No rules broken per se, just the fact that you've very aggressively defended your position and a little humility goes a long way.

I think the fact that some vehicles, and some drivers, are quite capable of safely exceeding posted reccomendations for corners is a given, however, plenty of reasons have been posted for people to consider the ramifications.

Classic example of how your words can be interpreted online, though.
Pays to think carefully before hitting submit, eh?

Now about RDD's...

Reference: Wikipedia

Only one type of Radar Detector is immune from RDD's, apparently. I dunno about 'Good ra{d}ar detectors' vs 'others'. Seems to me that pretty much Radar Detector on the market is using a Superhet and thus subject to the same vulnerability, excepting ones where the Local Oscillator has had its frequency moved beyond its range.
This is a similar practise to what is done to minimise RFI between any two radio devices which may have issues due to harmonic relationships so is not from a technology POV, spectacularly new.

yes ver true. in the future i will spend more time typing it out. sorry to all the peopl who i may/may not have offended. i will work at explaining it better.

yea i belive some more investigation is in order.

Not quiet simple as that.
Superheterodyne (it has been about 10 years since I built one) is there because you cannot make simple detector (like 1 diode with amplifier sort of thing) as sensitive and selective enough to detect relatively low level and very high frequency signals (microwave range). The reason why they emit is because of poor construction, it is possible to minimize (and remove almost completely) the heterodyne frequency leak entirely (like those Valentine radars, probably that is why their casing is alloy).

you know what forget it. clearly people are incapable of being able to accept what some1 else says. most likly due to limited brian capability on thier part.

ya know what, I often find my brian is the limitation...

maybe I should try a steve, or a todd?

[NZVengeance]

maybe I should try a steve, or a todd?

huh?
soory my brain is being a little limited atm :p

[postfach]

I don't really have the time to read back through the entire thread, but assuming you have a radar detector, that can't be detected, surely it still has to be somewhere on the car where it can "see" around the car ie front windscreen, since hiding it away somewhere is going to seriously impair its ability to function. Therefore, the police will still be able to see that you have one, and can pull you over and ticket you for it.

Unless someone has designed a detector that has sensors designed to be flush mounted in the bumpers or something?

Anyway, whether you have one installed covertly or out in the open, it will still be breaking the law, yes? Just a case of how long you can go without getting caught I suppose.

Side note: I was in parallel imported on Monday, I noticed they're still selling them, so I assume the're not illegal to sell/buy, you just can't use it?! I didn't see any warning on the cabinet about them not being legal either

I think the date is april 1st... can't find it off hand though.

[NZVengeance]

i dont have an undetectable one. however the bell remote mounted radars sit inside the bumpers and do not require to be visible. the blinders however do. but you can get little solenoids that drop the blinders down and bring them up to hide them as needed.

[rolla_fxgt]

I don't actually think the laws been passed yet, its just on the 'to do list' i guess you'd call it.

If & very hypothetical here, you could get a detector that doesn't emit & allow the cops to 'see it', & you could mount it in say the grill or similar, i.e hidden to a large degree, & you could have a flip panel (motorised to come down & hide the display of the said radar detector), or similar then & only then would i look at getting a new detector(s) (guess you'd need a rear looking one too).

I still live in hope of the day when they allow HARM missiles on cars & the mil spec radar receivers.

either that or we all buy mini rc helicopters & fly them like drones 1 in front & 1 behind the car at a slight distance & arm them with cameras & the software to scan for cop decals or lights on dash's.

But seriously safer & cheaper to stick within the limits we're given on the road. After all its not a right to drive on the roads, its a privilege

[skathed]

i hit up the buyer at my work about it being legal or not for us to sell them at my work. he just stated its a watch this space kinda thing. so we seem to still sell them. and people are still buying them even though they are aware of the possible fines ect soon to be inplace

Thats what you need for stealth installation and use and its very likely to be immune to the RDD's the police would likely deploy.

For those whose morality runs along such lines - Problem solved

Spector picks that up. Its not immune.

Only one it doesn't is the bell xr sti. And the bell isnt immune completely, as it still emits energy, its just at a different fequancy, but the police could, and may, build a new RDD to pick them up aswell.

[slighty_sykotic]

http://www.radardirect.co.nz/new/car_ra ... index.html

THAT is what you need.

I didnt even know it was out yet.

Its a remote form of the bell xr sti, like the one you linked to wildcard.


This one IS hidden and IS immune.

[Mr Revhead]

but for how long?

This is an email reply i got from bel radar



Thanks for your interest in Beltronics!
The RX75 has shielding from the VG2 type RDD. In reading our Australian distributor's website I found this information:
"Until recently, radar safety detectors were either completely detectable or only undetectable to 1 or 2 radar-detector-detector’s (RDD’s). Beltronics new model, the BEL XR, is the first radar safety detector to be undetectable to all RDD’s. It has been tested independently in a microwave lab for traceable emissions and it has also been tested against the latest version of the Stalcar III, the best RDD available. These tests proved the BEL XR to be untraceable to police RDD’s." You should visit this site: http://www.neltronics.com.au/belguide.htm

when looking for a radar detectior you need to look in the specs for this line

Read what you just said again. VG2 means shit all.

The rx75 is VG2 immune, but is still detecable by the newer RDD's.

ONLY the xr and the xr new remote verison are undectable at the moment. But if you have a look around the net, you will find articles that prove the xr still emits alot of "noise" so can be picked up, but a RDD will have to be designed just for the XR

[NZVengeance]

sorry typo on my part

VG-3 Immunity.

however

this i belive is the new unit theya re talking about

http://www.neltronics.com.au/BelXRC.htm

Full VG-2 and VG-3 immunity

[BlakJak]

All of this is just react and counter-react. There's only so many frequencies available and it is never going to take very long for an RDD to be come up with that'll pick up your Het.

So you get a year or two and then you're upgrading. Or sooner perhaps.

Seems to me like a whole buncha trouble for no good reason... if you're not doing anything wrong then the presence of a radar is no longer an issue.

Yup, that is true.

Only other factor is the number of the sti xrs around. It is worth spending mega dolalrs in R&D to develop a new one to pick up the handful of radars in the country
