That stuff about receiving high frequency waves from CRT's and stuff is also described in The Cryptonomicon (Neal Stepherson). They called it Von Eck Phreaking. Don't know if in RL it is called that way... but hey... He took it even to a further level: he claimed (in the book, prolly not realistic) that you could receive the high frequency waves from memory chips and thus could even phreak on laptops (i.e. watch the video memory)... Ah wel...
