The purpose of this page is to attempt to explain in simple terms, some of the questions lay persons rarely know to askabout the various technical aspects associated with the Rife frequency technology developed by JWLABS.

For more common questions, please visit our FAQ page.

At the turn of the decade, there were still original Rife machines in use; the schematics were published privately several times by John Crane. Though Crane was disbelieved by many, he was not wrong; he was simply in error about a few critical assumptions. One of his errors was his failure to understand the significance of the analog signal.

There have been many successes in cases wherein Rife technology has been employed, garnering keen interest from many quarters. Because of this, the true Rife frequency instruments have never been in anyone’s exclusive control.

Since the tradition of electro-medicine has been continuous since Albert Abrams, empirical knowledge is fairly vast and reasonably well established. The science has been proven and re-proven perhaps thousands of times in the last several decades. [Numerous approved devices are testament to this, the most commonly known instrument being the TENS machine.]

Probably the main issue we should discuss has to do with value versus hardware. Rife machine hardware, meaning the components that go into it, needs to be adequate to qualify as a genuine Rife machine. But nothing should be added to the machine that is not actually required. You will never see meaningless modalities on any JWLABS instrument that are intended merely to impress or to make the machine appear to have more value than it actually has. There are no exotic applicators that are any more helpful than those we provide.

An examination of the long evolution of applicator technology will reveal that the means of delivering current to the body have gone through many changes over the one hundred year history of Rife frequency technology. Until quality adhesive electrode patches were invented, the means of application were crude and fairly limited.

For the first fifty years, steel plates for the feet to stand on, and metal rods for the hands to grip, were about as good as could be expected. Though horribly inadequate, this was what Rife used from the earliest days. Even today, some Rife manufacturers use the rods and plates, and although it’s one of the authentic ways, this method has been obsolete for many years. There are various other experimental applicators, but these are mostly for show and do not actually add anything new to the therapy.

With our Model B, we eliminated many of the old time inefficiencies as possible, and we refined the original design. In this way, much of the crudeness of Rife’s originals was corrected.

Model B used an electron tube based amplifier, as did the original device. We did not have a therapeutic need for broadcast devices, which were basically accessories to the original frequency instrument. In Rife’s own labs, the Ray evolved back to its original transducer form in the later years.

There was never any real improvement from the 1933 machine because electronics moved along much more slowly then and the necessary parameters for an instrument did not change at all. Since that time, however, we have come to realize that although Rife established what the theoretical maximum should be for an instrument, some things needed to be adjusted. Many years of trial and error have shown that we need far more power than he used. About two and a half times that amount turns out to be what it really takes to fully create the effect in a living subject.

The issue of accuracy was easy to overcome by staging precision potentiometers and using a solid state oscillator. Drift still occurs, but it is reduced dramatically from what it once had been in the true analog machine. In fact, there is a certain benefit to some degree of drift. The natural downward drift of Rife’s original machines worked to his advantage in ways that later digital copies could not easily reproduce.

Some drift is desirable; in fact, many digitally based instruments actually try to simulate the drift factor to enhance efficacy. Russian researchers have pointed out that the moment a microbe begins to show effects of the treatment, the mortal frequency for that microbe (and all others similarly affected) immediately changes. Usually lower, by the tiniest fraction of a hertz. As it continues to deform, the exact deadly frequency it takes to keep killing it continues to  change accordingly.

There is a question regarding whether Rife actually knew about this. Certainly, those making poorly designed digital machines have never figured this out. This is part of the reason we have persistently endeavored to protect and preserve as much of the original technology as possible. [After many years in development, we were finally able to achieve this in our Model A, launched in 2004. Only then did we have a solid state, more user friendly device which preserved the integrity of the old style analog signal.]

The machine that uses less hardware without sacrificing any of the output quality makes it possible for more people to enjoy the benefits in a user friendly format. This is not very easily done. Although we have achieved this with our Model A line of devices, it has taken decades to develop and test, and the machine has had to go through many different embodiments at great cost.

Analog vs Digital

Another technical issue has to do with analog versus digital. Digital accuracy is certainly greater than is possible with analog, but it is the wrong sort of accuracy. The minor variations that are characteristic of an analog device may benefit the user but they must be simulated digitally, using still more complex hardware in order for it to approximate analog.

Of course, Dr. Rife never used anything digital, and the frequency tuning of most digital machines leaves a great deal to be desired. Unless a digital machine employs very complex programs, there are many frequencies that it will never be able to achieve properly. It’s effectively impossible to digitally simulate the perfectly smooth gradients of tuning that are inherent to an analog device of far less complexity.

In other words, if a highly refined analog device can split a single hertz into billionths simply by turning a dial, a single hertz simulated at that level digitally would require at least a gigabyte of information. Multiply that by the fact that the ten thousand hertz that are traditionally used in the therapy would require ten terabytes, or about six modern PCs computers, loaded to the gills to equal it digitally. Not impossible, but still a lot more than is feasible or affordable with the present state of digital programming technology. Again, this is easily achieved in analog by means of a series of simple potentiometers, albeit not cheap ones.

Output Power & Frequency Range

A common issue has to do with output power. There are limits to the amount of current energy the body can comfortably tolerate without harm. It has long been known that lower frequencies require far less energy to deliver effectively because the amount of deliverable frequency power, or signal, that can be delivered drops off exponentially the higher the frequency being used. Thus the lower frequencies require far less electrical potential to drive them.

Rife discovered the importance of frequency when he found that microorganisms can be viewed in their native colors. He did this through the use of a series of prisms and arrived at a system that could polarize the light spectrum for this purpose. In the strictest sense, these are the true native frequencies of the various microorganisms. But the frequencies of light can only be easily expressed by scientific notation because they are so high.

When he exposed them to the precise frequencies of light under the microscope, the microbes did not die, because the amount of deliverable energy by means of light is insignificant and far below the level that is needed to destroy them. He was forced by practicality to translate these light frequencies down the spectrum to lower frequency ranges so that enough energy could be effectively delivered.

One of the ranges that will do the job is the radio transmission range. These are frequencies measured in megahertz, or millions of cycles per second. This range turned out to be ideal for use with the microscope and will only destroy microbes when the precise frequency is achieved.

The big drawback of using radio waves to kill pathogens is the fact that the microwave range begins as low as 33 megahertz. Unshielded microwave energy, obviously, is not desirable in any instrument for the reason that it will kill off human cells just as readily as it can kill germs. Human brain cells are especially susceptible, as are certain nerves, reproductive organs and tissues of the eye.

In order to make an instrument that will not do the user any harm,
only the audio range is recommended.

The audio range is about the same as that of a piano. You can listen to a piano all day long and it will not harm you in the slightest way. In fact, music has other plainly observable value all by itself.

The resonance of a signal consists of overtones and undertones, just as they are observable on the piano. When you hit middle C, both high C and low C resonate. It is by this means that the mortal oscillatory rates actually work. 

Audio does not use the native frequencies of a microbe, these frequencies employ the resonances that are sympathetically generated. Resonance does not occur in the machine, they occur in the body. Also the same in a piano, it is not only middle C that resonates when you press it, it’s also the other components and the body of the piano that resonate.

Harmonics is what happens when you hit two piano keys at once. You do not get either frequency; instead, you get the harmonic frequency that is generated by the combined tones. For this reason, multiple signal generators are nonsense.

If you introduce two different signals into the body, you will only get the harmonics they create, and thus you will never know what the effective frequency actually is that you’re getting. In the worst case, the harmonics will reach frequencies approaching microwave.


One of the most important technical aspects associated with Rife frequency technology pertains to the square waveform a Rife machine generates. There are some very simple reasons why the only waveform a true Rife machine generates is a square wave. Introducing frequency into the body is like trying to play the piano underwater. The signal will be muted and sound very muffled. This is because as the waves of energy pass through the water, they are eroded by the natural kinetic resistance of the water.

The Rife machine has a much more difficult medium to penetrate, and it’s far more difficult to deliver the correct, coherent signal to the deepest tissues. The body has a lot of resistance and muffles the signal very rapidly. Literally, the signal flattens out the farther it travels in the medium of the body. In order to compensate for this, the square wave is used because it has the most total signal and so will maintain the frequency much farther through the medium than any other type of signal.

Some argue that Rife used a sine wave. That is more correct than is immediately apparent. The instant a square wave enters the body, it is converted by the resistance of the body, into a sine wave. If you introduce a sine wave it instantly goes flat, and does not deliver any frequency information/potential at all. This is true with all other waveforms as well — except a square wave.

It’s apparent to most readers that there is considerable disagreement about what constitutes the real technology Rife was using. There are even individuals who claim ownership of the technology, never mentioning Royal Rife’s name. Today, we see distributors of a multitude of devices, ranging from a low powered “zapper” to very complex devices with amplifiers, coils, tubes and so forth. Lots of bells and whistles. All claim to represent the only true Rife frequency technology.

Some proclaim that it’s light, or radio, that produces the beneficial effects, so they have you sit in a room with others and beam very high frequencies at a group of folks. No question, light may have healing properties. Radio waves heat the tissue which may have beneficial effects, but there are downsides.

In particular, we alert you to what we have said from the inception of JWLABS: radio frequencies have the potential to harm human cells. The brain, the eyes, even the heart may be especially vulnerable. This is not to say that in the hands of a skilled practitioner these machines won’t be helpful.

After many discussions in the early 90s with Dr. James Bare (a developer of broadcast devices), John Wright affirmed his position that low frequencies in the audio range were the safest, and in many cases, the most effective. The two proceeded on separate paths, with Bare embracing the broadcast method and Wright committed to direct contact audio frequencies.
