how woudl you if it's even possible making t.v. stations flicker so that everyone in my city whos watching will see the flicker.

you could make some sort of "video-sender" out of parts of an old VCR, perfectly legal in america i think, but not in the UK.

Highly doubtful it would affect a whole city...

moving to radio free amerika, those guys have more information on propagating TV signals.

A really high power spark gap transmitter should do it. They are really easy to make, just do a little search of the web, I don't really have the motivation to explain it right now.

what about making a FM oscillator and boosting the signal some how, im sure it can be done. i made a small FM oscillator using a 9 volt battery that flickered and caused interference,i also read that adding an antenna could boost the range up to 25 feet with the small 9 volt i used. its an idea

How about you build a tesla coil set to resonate at the frequency of the TV... I know that's a fairly high freq for a tesla, but it has been done hasn't it? And the power those things can put out is amazing... PLUS as a added bonus, you get to see the pretty sparks... ooooo fireworks

http://www.amazing1.com/security2.htm fifth one down. And a question where it says dont connect to antenna correct me if im wrong but would that amplify the device making all the TVs in the neighbor hood go out?

how about a huge fuker of an emp bomb then they wouldn't even fliker =P

Sorry to ask this, my knowledge of radio's, etc. are still very basic at the moment But wouldn't that only affect people getting tv through the air waves and not people who subscribe to cable?
