    I could care less about his tests and what he spends as that is his choice. I test my detector DAILY in actual radar traps. Other Cobra owners test them this way also. Just look at amazon at the overwhelming happy Cobra owners.

    The whole purpose of his test is to to come up with something to bash cobra's with quite frankly as is evidenced in his writings.
    Obvious troll post is obvious.....

    You couldn't be more wrong about me being a Cobra basher. Less than 0.1%(probably much lower) of my posts here even reference Cobra. The truth is that Cobra has fallen way off the pack, ever since Ka band was introduced. I used a Cobra Trapshooter 3100 back in the late 80's that worked great against X and K bands. I loved that detector until it became obsolete with the advent of Ka band.

    I couldn't care less about Cobra. What I do care about is people making baseless claims such as:

    I think you're wrong about this. I'm of the opinion that the Cobra we tested at the last GoL uses the exact same platform as do the current top-of-the-line Cobras. That said, I can't back that up. So, I bought the exact same Cobra XRS-9990 that you use and base your claim off of. It arrives today. We'll know soon enough if today's Cobras are truly improved, as you claim, or if they are no better than the Cobra GoL tested a few years ago.

    So, to reiterate, I couldn't care less about what Cobras. What I do care about is people making baseless claims, especially if they turn out to be false. We'll see. The videos will tell the true tale.
    Haha, the old Trapster. I remember it, good detector.

    As for you Mandingo, I'm sure DJRams will perform an unbiased, equal test of the Cobra RD. I'm willing to bet money that it will be a little sluggish against Ka Band.

    How much did the RD run you back DJ? Do you have a Vector 995 or a BX65 to make a comparison?
    you do huh? and mcdonald's doesn't put pink slime in it burger now either and never did. LOL !

    I have a 9500ix to compare it to, but I don't plan on doing anything but real world testing, so I'm just going to run it along with my STi-R Plus to ensure there is no interference. It cost me $100 + $7 shipping.
    I got mine for 70 dollars plus tax and a month's return policy.

    I had tried a few other newer Cobra detectors out for a month that performed far better then I expected and had ordered a newer xrs off the internet. Was about to return the latest radio shack one to get the money back toward this much newer model when I saw this clearance deal.

    sent the one I ordered back unopened.

    It's very nice Radio Shack offers detectors with a month's return policy.

    UPdated this one with the aura system when It turned out to be even better

    I like it a lot and it's worth the money even though I don't have the lifetime deal.

    of course you will never get it to try it out.

    with this system it's a great deal.

    The bears test mine every day and it performs as well if not better then any detector I have ever owned so far.

    It has been a pleasant surprise quite frankly

    Something I can't say for my pro whistler unfortunately

    amazing how rejuvenate this old forum gets when there's a possibility to trash on something.

    especially a Cobra !

    IIRC You said you have owned a V1,correct?

    Nope, I HAVE a v1.

    I get it out for sh-ts and giggles sometimes

    I thought of running them both together but it leaks awful to my Cobra and not the other way around LOL !

    Imagine that

    many detectors set off the Cobra including bel models but the xrs doesn't do it back

    Clueless cretins rag on all Cobra's like the company made only one model all these years.

    but your not one of them of course

    Neither am I.

    Even you can admit Mandingo, for the past ten years, Cobras RD's haven't been all that good. I've seen several come through my store, and for the most part, were unimpressive. The 9990 is a step in the right direction, granted, but that doesn't exclude a lot of the other junk that Cobra has made. And, make no mistake about it, Cobra has made some pretty junky RD's.

    Of course I can. Certainly I have a cheap old RSA Cobra that is AWFUL !

    and cheap whistlers are awful too btw.

    Someone at Cobra finally noticed the complaints about the brand and decided to do something

    these new XRS models are FAR FAR better

    that is a very good step in the right direction.

    but to bash all Cobra's now and claim they are all junk is frankly just ill informed

    and many times when these people SEE that all Cobra's aren't bad anymore they still choose to bash the brand.

    I can tell you this for certain. There are plenty of Bel and whistler units out their that put out tons of leakage too.

    The brand new TSR equipped 995 I just bought for one sets my Cobra off something fierce.

    Which detector is setting off the other detector isn't an accurate way to tell which detector leaks more. The reason the Cobra alerts to the Bel, but the Bel does not alert to the Cobra is because the Bel has better filtering.

    The truth of the matter is that Cobras leak like a sieve, nore than any other brand I've tested. Anyone with a Spectre can attest to that. A leaky detectos LO emissions may or may not make another detector alert, but that has less to do with the leaky detector and has more to do with how well other detectors filter out the detectors with the leaky LOs. LO emmisions have 2nd and third harmonics that sometimes fall into the K and Ka band. Other detectors have to filter these signals out. It's more complicated than this , but basically, detectors filter leaky detectors by verifying that the K or Ka band signal that they have detected, is not accompanied by the corresponding first and/or second harmonic. Having to constantly filter this stuff lowers their performance of the detector having to filter out the leaky Cobra and raises the radar detection noise floor.

Although the LO is generated inside the detector, in most cases the LO is "leaked" or "transmitted" from the radar detectors. Many detectors on the road have a 1st LO that operates in the 11-12 GHz range. The problem is, that these LOs also produce "harmonics" at multiples of the LO frequency. So, in once classic example, an LO operating at 11.558 GHz would produce a harmonic at 34.674 GHz, well within the valid bandpass for a Stalker Ka radar unit.

    Of course, this poses a problem for detector manufacturers: they must filter the Ka false alerts caused by these other detectors on the road, while still providing superior protection against Ka radar.
