Beat detection occurs in the detection circuit of the receiver. That could be resolved easily by the use of appropriate filters on the front end amplifier. For example, your receiver is supposed to be from 1-10Khz, and you detect a signal at 7Khz. If it's a beat signal caused by frequencies above 10khz, then eliminating them is done by using a 10khz low pass filter in the pre-amp.

"it might be that they are highly directional and are strongest at certain locations at different times."

So then, would not another person checking for the signals help?

"In any case, this is not a productive direction in which to focus efforts at the moment. It is more important to get the computer programming and government contact work done."

This is EXACTLY what I'm talking about.

All your work in programming a website and contacting governments with warnings is USELESS if your detection method is fundamentally flawed. Whether it is flawed or not cannot be determined because you won't talk about it.

You're getting the cart before the horse. When testing a hypothesis, you have to start with the fundamentals. When that pans out, you test it. When that pans out, then you can start bragging about it.

To be honest, I am curious about the idea of faults somehow generating electromagnetic signals of some type. *Some* of the possible explanations I find are reasonable. But so many people come up with an idea and allow it to devolve into pseudoscience and start spouting gobbledygook.

"They are in my opinion invaluable earthquake warning signals."

You're "opinion" matters little to hard facts. And, it is a well known logical fallacy when one only looks for facts to support their pet hypothesis. One must also try to tear it down to make sure it's strong enough.

Have you sat down and really pondered what could be wrong with your idea? And I mean really tried to tear it apart?

Einstein's Theory of Relativity is widely considered to be the most tested theory of all time. Every test so far has supported the theory. Yet, all it would take is but one failure to break the theory. Only one.
