True, but if the display range and bandwidth was tunable, and shown in 3-D chroma (similar to thermal imagers) rather than time domain -the emissions would make sense to the wearer. After all, even modern spectrum analyzers cannot show full bandwidth without compromising adjustments.

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.
