I think they already do send random signals. I know with my Cingular Wireless phone, it emits a hum through my PC speakers and TV speakers. This is
when the cell is on, closed, and not in use. Which leads me to a question. Can the NSA use this signal for surveillance (listening bug) or even a
WiFi type of surveillance device to see what you are doing on the PC, listening to on the radio, or watching on the TV?
