Easy to stop that Hulk. If you look at things that connect via usb to a pc say, if you look on the cord at some point on it there will be a little cylinder maybe a different shape, it is to knock down rf signals. In all reality it is a magnet or a few little magnets in there. When I was using hps I bought some that just snap around the cord of your ballast, which will knock down the rf signal the ballast puts out. My  terminology may not be right on but you get what I'm saying. Like the cord that connects my camera to my pc so I can pull pics to my pc has one of them there things I'm talkin bout.
