How real are the mass deatruction threats told by news channels and media? This US news channel is talking of some star treck style device which according to them can take out all electronic equipment in the north america,and they claim that its so simple that even the terrorists can make it.

And discovery channel claims that there is an 80 percent probability that such a weapon is available for use.

Sme other website say differant things about such a "thing",
Oh well,there are bigger real threats to humanity such as powerty,global warming and water shortage.

But then i remember,long time ago i had a notorious neighbour who's tele was always very loud and he wont lower the volume even at late in the night.Me and some other neighbours made several polite requests to him,but he was not bothered.He didn't have cable or satellite receiver,just ordinary antenna.Me and another friend did some research and built a basic but fairly powerful FM transmitter and deviced a way to direct it's transmission in the direction of neighbour's antenna.All we had to use was a 9 volt battery,some aluminium foils a car ariel and a cheap circuit board.We did not damage his tele,but we did block or deteriorate the TV station's signal,as his antenna was receiving our device's transmission,because it was more powerful and nearer.Since our device was not transmitting all around,but in one direction only,we escapes being detected.There is a military base in my home town and they regularly scan for unliscenced transmitters.
For a few days all was quiet and it was fun when occasionally he mentioned to us that his tele is not working and no matter how he adjusts or tunes the TV,the picture is very bad, and then he bought a satellite receiver with a huge dish antenna,and all was back to normal,even worse :))
