Build a Jacob's ladder running at 10kV and 1/2 an amp. That'll wipe out most AM and FM transmissions below 10GHz for a range of maybe 500 to 750 meters radius. You can't easily jam lasers, you need to know where they are. And it is difficult to jam code division spread spectrum too, but if you can get close to the receiving antenna you can make it hard to find any transmitters for a while. But you will be noticed :-) Patience, persistence, truth, Dr. mike
