The term is something of a misnomer. Rife did not invent the transducer. It had been in use a long time before he was born. The technology and techniques we employ in the thing we call Rife therapy, was mostly developed by others. An electro-medical society was established in the US by 1890. The frequency instrument, in modern times, is actually a home remedy device that incorporates virtually everything that can be done with an electro-medical device.
     Royal Rife was a microscopist, (someone who makes and develops microscopes). He is correctly attributed as having discovered what are called Mortal Oscillatory Rates, or, the frequencies that devitalize microbes. That function of the therapy, has always been best accomplished with a transducer. An instrument that delivers current to the body that is both a stimulus to the user, but is a destructive force to pathogens of all kinds at the same time.
     The other school of thought is to the effect that it was the Ray Tube that was the true Rife machine, a device that uses a radio wave to deliver frequencies, rather than current. In a way, there is a dramatically correct aspect to this belief, since the transducer could not be used to treat Rife's microscope. This is because they are too powerful.
     Transducers will generally kill anything that lives on a microscope slide, at any frequency, because it takes so very little current to kill bacteria or virus in a subject of a single drop of liquid, with no resistance at all. What Rife needed was to prove his theory. In order to accomplish this, he needed a frequency applicator that would ONLY kill one type of pathogen when precisely the correct frequency rate was reached, leaving every other type unharmed. Thus affording a means to produce obvious and dramatic proof. The ray tube was used for this purpose, and it was powered by the frequency instrument. The frequency instrument was the transducer. The transducer was the frequency instrument.
     Of course, Rife knew enough about physics to understand that far more energy than a broadcast device could produce was needed in order to achieve the same sort of results inside a living body, where huge resistances would be present. Ray tube promoters were ignorant of these simple facts before they committed to a different paradigm. The only part they are correct about, is that the Ray tube was the part he invented.
     Over the years it has been proven that even a very feeble transducer vastly out performs even the most powerful ray tube modalities for the reason that a transducer is direct, and broadcast, is indirect. There are a great many other things that make the transducer a far better method of delivering frequency to the body. The most notable of these is that of the electrocution of pathogens. Something that no non-contacting instrument can do. Obviously, it is far easier to electrocute pathogens than it is to destroy them by frequency alone. Far more reliable as well.
     JWLABS machines deliver the mortal rates at an energy output that is also an electrocuting force to virus and bacteria. This makes the effect a lot more reliable and predictable. There are a host of other effects that can be realized using the transducer, and that are not possible in any other way. The Department of Defense verifies this for us in the document, Electro Conformational Coupling, where endergonic reactions induced by oscillating current are described in detail. They include cyclic enzyme catalysis, mitochondrial ATP synthase, and others. There are many others.
     In the loose language of the present day, virtually anything that delivers frequency to the body might be called a Rife type device. Although there is literally no better or more powerful way to accomplish this than the transducer, frequency delivery devices have taken many diverse forms, from color therapy to the playing of certain musical instruments.
     John Crane, who built machines for Rife for over 20 years, attempted to reveal all of these facts after Rife's death in 1971. His focus was primarily on the fact of microbial electocution, which Rife never revealed. Even though he knew and had proven it's effectiveness, Rife did not openly admit it, again, because he did not invent the transducer. But he did prove it, so the name has stuck.
     To reiterate, Rife did not invent the Rife machine, and what he did invent, was not appropriate for human therapy purposes. The reason why it is not appropriate for human therapy, is really very simple. Broadcast devices product microwave energy, which kills human cells. It is much the same energy that one would receive being too close to a radio, or TV broadcast tower. Users report severe memory loss. Frequencies that even approach microwave, are not healthful for therapeutic purposes. These are the very same dangers people face using cellular phones. Microwave causes cancer, leukemia, lymphoma, and other serious disorders.
     Memory loss caused in this way, is not perceptable. It is very similar to the loss of mental function that occurs during oxygen deprivation. You cannot tell it is happening to you, because the very faculty that would normally be present to alarm you of the distress is also the very faculty that is being lost. So, you just get dumber and dumber, never realizing effects that are not perceptable.
     This is the reason why JWLABS does not make a broadcast device, and we never will. It is simply much too dangerous. And it is a danger that users cannot detect, that produces injury doctors cannot diagnose. Royal Rife, John Crane, and others who worked with them for years, have all died in a terrible diminished state of mental accuity. Alcoholism, erratic behavior, dementia, and sutpidity seem to be common among them.
     So, there is really no cut and dried definition of what a Rife machine is. But there are a few things that we must be sure a Rife machine is not. By our definition, a Rife machine is something that does the user a lot of good, and that is scientifically sound in its design, and empirically safe for home use. A Rife machine is not supposed to be dangerous, or harmful during normal use. Broadcast, or "ray machines" violate this basic safety rule.
