Yeah, except all those hippies who can't afford their TV license fee also happen to have lava and fiberoptic lamps making that whole 'looking through your window to watch the reflected colour patterns' creepy shit kind of pointless.
- nitrogen 16y agoI'm not in the UK, but I think they just scan for the intermediate frequency used by TV receivers. The receiver combines the TV signal with another signal that's something like 10 or 16 MHz away from the broadcast frequency, in a way that results in the TV signal being shifted down to ~10-16MHz, where it is easier to decode. Some of that additional signal leaks back through the antenna, or is otherwise emitted by the equipment. For example, to see if you're watching a station at 87MHz, they'd scan for emissions at 77 or 97MHz. No window spying necessary. Corrections by those better versed than I in RF electronics and antenna theory are welcome.
