[QUOTE="JimJ, post: 1289807, member: 555251"] I got a chuckle out of that page [IMG]//content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif[/IMG] Passive jamming of a radar signal, by its very definition, is a silly concept. "Reflective receiver"? Who do they think they're kidding? Once you've disrupted the RF carrier, you have to get it back to the cop somehow, I wonder how that happens...yup, it's transmitted back. And the thing still has an IF signal that, although you can attenuate it, will still be able to be received if you know where to look for it. If I really wanted to jam police radars and not have legal ramifications (well, of the same magnitude [IMG]//content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif[/IMG]), I'd build myself one of these: [URL="http://www.wavelen.com/projects/24ghzWB.html"]http://www.wavelen.com/projects/24ghzWB.html[/URL] [IMG]//content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif[/IMG] Also helps that I have a license to operate something like this near the major police radar bands [IMG]//content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif[/IMG] Some more interesting reading...
