It's my understanding that TV detector vans work by picking up the radiation emitted by cathode ray tube TVs - which should mean that, if you're rich enough to run an LCD monitor they'll never know you're a secret Paxman admirer.
A popular, but false, myth. The video cards radiate more than the CRT's. Laptops tend to be the worst offenders.
Cables are a problem, too. Video signals from a fully-shielded computer connected to a fully-shielded monitor by a regular, unshielded cable can be read. Effective snooping distance goes down, though I don't remember by what factor. -- Steve Furlong, Computer Condottiere Have GNU, will travel 518-374-4720 sfurlong@acmenet.net
