Hi, Palmtops are noisy, this is bad for Van Eck. Van Eck relies on the fact that the device is emitting display signals significantly above the noise floor or that there is a method to pull that signal out of the noise. Considering the power draw of palmtops, while they are noisy they are also very low power. My guestimate on emitted rf is in the micro-watt range. That means for a succesful intercept the receiver would need to be in most situation within feet of the device. It'd be much simpler to simply ask to see the PDA because you were thinking of buying one than lugging all that obvious equipment around... If you want to defeat Van Eck you want either very quite or you want lots of noise smoothly distributed across the rf spectrum. ____________________________________________________________________ | | | The obvious is sometimes false; | | The unexpected sometimes true. | | | | Anonymous | | | | | | _____ The Armadillo Group | | ,::////;::-.
