Here are plans for a TV jammer. It's a very low power device just like the one I built in high school electronics. It doesn't work on cable TV or satellite TV. Also, I think at the time, the power was too low to be relevant. http://www.olimex.com/kits/rf003.html
I think the soldiers warming up in front of a radar dish is an urban legend - or perhaps, a military legend. I heard this when I worked on radars. If anyone did do that, they would be severly burned internally. It may have happened once to some hapless soldiers, but they wouldn't be doing it the next day. The RF energy from 2.4 GHz (operating at 1000 watts or so) penetrates the outer layers of skin and heats up the underlying layers first. By the time you would sense any warmth, there would be extensive thermal damage to the underlying tissue. Here's a good writeup from the FCC website: http://www.fcc.gov/Bureaus/Engineering_Technology/Documents/bulletins/oet56/ oet56e4.pdf -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Paul Carlin Sent: Monday, October 20, 2003 7:24 PM To: [EMAIL PROTECTED] Subject: Re: [SOCALWUG] 802.11 Jammer When I was 12 my friend and I made a "TV" Jammer that ran off a 9V battery. We drove the old man downstairs crazy when he tried to watch ABC News. I don't remember fearing for a second that the FCC would drive up in a white van. However, I don't think I'd recommend open door microwave ovens in a classroom. That might be borderline stupid. Eighteen year old soldiers in Alaska used to stand in front of the military radar dish to warm up... they didn't quite understand why. > And of course, the "jammer" you are trying to make, > will be highly illegal, and the FCC can drive up in > their white van and haul all your electronics away.
