Speaking of TEMPEST....
I was able to procure a tempest specced HP Laserjet + (model 2686 TA), used around a year ago and recently did a motherboard swap to upgrade the unit to 2mb of RAM...wasn't all that much to rip apart and put back together...even with all the damn machined-screws and shielding, the thing still emits a fair amount of noise, but no farther than the room it's in... I checked all my cables and system box and switched to shielded cables and cleaned up the the noise as best I could...interesting design and at least I would see the damn snoops...they'd have to be in my front yard to pick it up...anyone else hack any used TEMPEST stuff?

How does one go about testing such a thing?

Anything that is interfered with will work, but listening to an AM radio tuned to maximal interference is easy. When you have no audible interference, though, it just means that there's none left that this will pick up.

Technically, sure. But you'd need some kinda broadband licence to operate it... legally.
