He believes what he hears. People are telling that there is a big difference between when it's on and when it's off. That is what he's going by. I heard a Big difference between on and off.Well, he did say the he believes what he see. I think you are right. I also think he needs to get a $75 50mhz O-scope, a 100w dummy load, and use that wattmeter he is happy about. He can easily build the sampler and watch a few videos on YouTube on how to use a scope. Then he will know what some of these hucksters and scam artists are all about.
