Yes, it sounds much more attractive than a sniffer, which would produce BAD smells around some equipment. And it isn't technically unfeasible. The problem is the poor resolution, even a microwave frequencies, due to the wavelength of the emission. At 150 kHz, the wavelength is 2 km, so only very BIG things are visible. -- Regards, John Woodgate, OOO - Own Opinions Only. http://www.jmwa.demon.co.uk This message and its contents are not confidential, privileged or protected by law.
