You use your origional units, I'm sure. I don't doubt tey're very effective, but I'm pretty sure you don't use any of your units made since the FDA raid. That's the pivotal point in the start of the corruption. So any up to that point were probably pretty good as a multi-frequency rife machine with the clark style square positive off set wave. Covering all bases--it's a goo idea, but as Clark saw, very vulnerable to being corrupted.
And AM frequencies are below the human range. And the fact you were bragging at how much umph your units have, doesn't really convince me they can't amp the human frequency ranges just fine.
You say that only you touch the chips and test every unit--I see that was true, but I don't see that any more, Sorry. I'm looking down at my hands (obviously one of the FDA goons), putting a blackish chip in and then sealing it. I see you at a work bench over on the other side of the garage.
