Well then you better get your facts straight. First, I never said a tube is a circuit. You are the person who made that reference. I only talked about a length of tube as an example of how it resonates with sound waves of the same frequency as the tube. If you think that is BS, you are mistaken. Any high school science student knows you are wrong about that.
If you want to try to imply I consider a tube an electronic circuit, you are also wrong. I didn't make any statement to that effect. You did. This is where you introduced BS into the concept of resonance. And it is analogous to passive resonant electornic circuits such as a coil and a capacitor. If you doubt that, you could ask any acoustic engineer who knows the answer. They are very familiar with the concepts of tuning the frequencies and impedance matching in acoustics, just as electronic engineers are familiar with resonant tuning and impedance matching in electronic circuits.
I have not introduced shenanegans into the concept of resonance, you did the moment you claimed tubes and seashells make a good circuit. I only made an analogy of resonance in two different mediums, and questioned your implications that the Examiner may be subject to FCC registration. The fact is the Examiner does not contain any transmitting equipment or power amplifiers that I am aware of, nor is it capable of creating any EMI/RFI interference above the background levels present in the air. It is claimed to be a passive receiver circuit that amplifies minute external signals through the principle of resonance. If it does indeed create EMI/RFI interference problems, then I am not aware of these problems or any FCC registration requirements.
It does not make you appear any closer to correct about how resonance works, or whether FCC registration is required even when you try to obfuscate the facts.
