Frequency Generator

What is a Frequency Generator?

A frequency generator, referred to by some as a “Rife machine”, is a research instrument used by practitioners, clinical researchers, and private researchers alike, in an attempt to influence the body in making chemical changes by using bio-frequencies, or “sound waves”. Frequency generators work on the principle of sympathetic resonance, which means that if there are two similar objects and one of them is vibrating, the other will begin to vibrate as well, even if they are not touching. In the same way that a sound wave can induce resonance in a crystal glass, and ultra-sound can be used to break up kidney stones, it is believed by many researchers that frequencies can be generated to stimulate organ function or physically vibrate offending bacteria, viruses and parasites, resulting in their elimination from the body.

A Brief Background

The first modern publication on the subject of bio-frequencies (that this author is aware of) was by Nikola Tesla in 1890. A whole branch of medicine was founded on the healing effects of certain Tesla coil frequencies. Tesla understood the therapeutic value of high-frequency vibrations. He never patented in the area, but did announce his findings to the medical community, and a number of devices were patented and marketed by others.

Patients, by focusing certain frequencies on afflicted areas, or in some cases just sitting in the vicinity of vibrations from a device like the Lakhovsky Multi wave Oscillator (which produced a blend of specific frequencies) experienced relief from rheumatism and other painful conditions. It was even considered a cure for certain types of paralysis. Such radiations increase the supply of blood to the area with a warming effect (diathermy). They enhance the oxygenation and nutritive value of the blood, increase various secretions, and accelerate the elimination of waste products in the blood. All this promotes healing. Reversals of cancer tumor growths have been documented.

Electrotherapy devices were sold directly to the public via ads in popular magazines and in the Sears catalogs. Self-treatment was widespread. (This easy access to treatment of all sorts of conditions led to the eventual suppression of the technology by the medical establishment!)

Later, in the 1920’s and 30’s, Raymond Royal Rife is another man who began exploring this phenomena as it relates to people and the pathogens that make us ill. He built a wonderous microscope that used light to actually see these microscopic invaders with his own eyes. He watched, while applying radio frequencies in an attempt to create a sympathetic resonance for each sample. Today’s modern frequency generators are largely based on his devices. This article by Barry Lynes has a good summary of Dr. Rife’s work. ( Royal Rife was issued a “Doctor of Science” degree by the University of Southern California in 1935 for his work with the microscope and beam ray instruments.)

Later, in the 1990’s cellular physicist, Hulda Clark PhD, also applied this science to uncover and “map out” the unique bio-frequencies generated by hundreds of parasites and bacteria that she found inside our bodies. Rather than light, she uncovered these frequencies by sound, by using a “listening device” of her own design. (The Syncrometer) Her work helped to further support the validity of applied bio-resonance science. Later, she developed another device called a “ zapper ” that was loosely based on the early devices of Dr. Rife.

Common Questions
(see the FAQs for more details)

Audio Frequencies vs. Radio Frequencies – What is the difference?

In a nutshell, Radio Frequencies (RFs) are higher than Audio Frequencies. The science seems to say more power and more cycles per second (higher frequency) allow the signal to penetrate more deeply. Many of the first known frequencies from the 20’s and 30’s were in the millions of hertz range. (like our generator)

So why do most of the instruments built today only use low audio frequencies, when original frequencies were much higher? The FCC (Federal Communication Commission) is the main reason why. In 1935 Congress created the FCC and by 1936 they began to regulate the airwaves. Before 1935 there were no regulations to prevent Dr. Rife from using his high frequencies output through a plasma powered ray tube. The frequencies output through the ray tube would travel about 12 miles in each direction from his laboratory, and would. Dr. Rife said his equipment would “raise the devil” with all the radios.

In 1936, Philip Hoyland built the first audio frequency instrument. (right) In these early designs, a radio frequency was used to “carry” a newer set of lower audio frequencies into the body. (like our generator does)

n the 1950s, Rife’s research partners John Crane and John Marsh continued to build this lower audio frequency instrument, using simple off-the-shelf technology of the day. From this time on, Dr. Rife’s original high frequencies were no longer used in any of the equipment, nor were his RF carrier waves used. Most of today’s modern frequency generators are patterned after these early 50’s style instruments.

Without the RF carrier frequency, they couldn’t get the same harmonics and penetration as the earlier ray tube instruments. This is why our frequency generator does use a RF carrier wave. A very simplified way to think of this is this: when you hear a song on the radio, it is audio frequencies that you are hearing. However, these audio frequencies are brought to your radio antenna by a modulated radio frequency, or “carrier wave”. The audio frequencies are “piggy backed” onto the radio frequencies. This “RF” carrier signal simply delivers the lower audio signal deeper. (which is what you want)

Square Wave vs. Sine Wave

Another debate within this field is “which wave format to use?” Before the newer instruments were developed, all the generators output only radio frequencies, or “RF”. When emitting these radio frequencies, the sine wave format is produced. Basically because this higher frequency range (in the millions of pulses per second, or hertz), creates a wave form that is naturally rounded at the top and bottom. It’s more difficult to create very sharp signals at this high rate of oscillation.

With advent of the newer Crane/Marsh design, the rate at which these signals are emitted dropped substantially into what is referred to as the Audio Frequency range. (this was not a desired design aspect at the time.) With these lower frequencies, the signal can be very sharply turned on and off, as seen below. This square wave design is used when running the lower audio frequencies. One important reason is because it helps to better create entrainment between the signal being emitted and the target. The principle of entrainment is at the very foundation of this entire science.

Entrainment is defined as the “tendency for two oscillating bodies to lock into phase so that they vibrate in harmony.” It is also defined as “a synchronization of two or more rhythmic cycles”. The principle of entrainment is universal, appearing in chemistry, pharmacology, biology, medicine, psychology, sociology, astronomy, architecture and more.

In the radio frequency range, a sine wave pattern is generated. (above 40,000htz)

Sample Sine Wave

Signal gently rises and falls. Can vary the rate of this rise and fall, top and bottom limits, etc…

In the lower Audio range, a square wave pattern is desired. (below 40,000htz)

Sample Square Wave

Signal sharply turns on and off. Can vary the rate of this “on/off” signal. This is a “50% Gate Rate”, meaning the signal is on and off 50% equally.

Analog vs. Digital

The question always arises about the type of signal that should be used. It is generally accepted that the most effective of these frequency generating devices will deliver an analog signal, versus a digital signal. Analog is better because it is in many ways a more natural frequency with a natural “float”. It includes the sub-tones and overtones to the base number, providing a maximized fullness, essentially a richness of tonal qualities. A very big part of that is what is called the harmonics. An audiophile understands this. Those who desire only “true” sound on their stereo systems insist on analog devices for just this reason.

The current analog vs. digital discussion is wrought with misconceptions and disinformation. Such as, digitally generated frequencies do not vary, which implies that they do not have overtones and undertones. This would only be true if the frequencies remained digital. That is why digital frequencies from DDS (Direct Digital Synthesis) and DSP (Digital Signal Processing) are converted to analog before they are put out of quality generators. These Digital-to-Analog Converters are called a DAC for short. You can see in the diagram below that a frequency comes out of a DDS or a DSP looking like stairs. The signal then goes through a DAC or Digital-to-Analog Converter. Then it goes through a Low-Pass or Bandpass Filter to finish the analog conversion. Now the frequency that you have is a very accurate analog frequency with all the overtones and undertones of that analog frequency. The analog frequency produced by a digital chip can be swept up or down with more accuracy than any old tube analog instrument. The most important thing to remember is the frequency has to be converted to analog before it is output from the frequency generator.

Digitally produced frequencies converted to analog are far superior to any signal that comes from an old antique tube type analog frequency generator. Antique tube type generators are very limited. If I want a frequency of 2128.5, an old tube analog generator would not be accurate enough to give me that frequency to use. It could only give me 2128. Also, digitally converted frequencies allow me to sweep with far more accuracy than old analog tube type instruments. Even a thousandth or millionth of a frequency is possible even though this kind of accuracy is not needed. This is something that a purely analog instrument could not do as accurately. Digitally produced frequencies when converted to analog can accurately produce minute details. These analog frequencies when converted to a square wave waveform produce square wave harmonics. Some claim that their instruments which output analog frequencies produce advanced analog harmonics, but this is just sales hype. All the digital to analog frequency generators on the market today that have been tested with a spectrum analyzer produce the same analog harmonics. Anyone claiming to have some form of superior advanced square wave harmonics is just giving you lots of sales hype. (Our frequency generator uses this technology, of course.)

Output of Contact type instrument vs. Ray Tube?

Direct contact, or ‘pad machines’, instruments deliver frequencies through direct contact using plates or cylinders, while plasma ray tube instruments transmit frequencies indirectly through the air. Direct contact makes it possible to get the full energy into the body without power loss. The tools seen here use cloth covers also that are used wet. The moisture improves conductivity.

Indirect contact though a gas filled tube (usually plasma and/or argon) is efficient also, and allows for a ‘hands free’ application. However, beware those who claim that this works “as long as your in the house with it”. These are great, but you DO have be very close to it for true therapeutic value.

The laws of physics in regards to signal loss come into play when using a ray tube. It requires much more power to deliver its output. For every foot that you move the ray tube away from the body you have to divide the power output by the ray tube by a factor of 4. Example: If you have 50 watts of power coming out of a ray tube, then at one foot away from the ray tube you only have 12.5 watts. At two feet you only have 3.125 watts and at 3 feet you only have about .78 of a watt. Because of this loss, researchers and doctors from the 30’s had to stay within 6 to 12 inches of the body with the ray tube. Today, many ray tube instruments output about 100 watts or more. Their manufacturers recommend those who use them to stay at least 3 feet away from the ray tube. At one foot away from the ray tube you only have 25 watts. At two feet you only have 6.25 watts and at 3 feet you only have about 1.56 of a watt. Many people believe that you can simply sit in the same room with one of these plasma ray tube to get the full effect… this is incorrect! With a direct contact instrument, this power loss is not a problem; therefore, one does not need to use anywhere near the same power levels used by a ray tube instrument.

Why Power Output Is Important In A Frequency Generator.

When comparing various instruments, power output is an important consideration. The first direct contact style instrument developed by John Crane and John Marsh worked well, but were underpowered like most of the pad instruments built today. Most modern contact pad generators’ power output is only about 0.20 of 1 watt, and they run just 1 frequency at a time. Our generator, when running in “Audio Mode” runs up to 8 frequencies simultaneously (huge time saver) with an output of .75, or 3.75 times more power. When used with the optional RF carrier turned on, max power output is 5.4 watts and is nearly 30 times more powerful than these other instruments. With the use of the optional 30 watt max amplifier it is over 150 times more powerful than the .2 watt standard.

Car audio is all about the power ratings. The objective is to match up the power of your amplifier with the power handling capabilities of your speakers or subwoofers. Seems simple enough…until they throw around words like RMS, peak, max and dynamic and then throw the word “power” after it. As a basic rule of thumb, RMS power is considered true power and all other ratings are relatively mute when making comparisons or finding that perfect system. Below I go a bit more in depth with the different types of power.

RMS Power Ratings:

The RMS power rating is the measure of continuous power that an amplifier can output. RMS power is derived from Root Mean Square, which is a statistical measurement of the magnitude of a varying quantity and is applied to voltage or current. Yeah…you can disregard that and just concentrate on the fact that RMS power should be what you use to compare any similar products. Even the RMS power has its flaws and inaccuracies, but for the most part it’s the most accurate depiction of real, continuous power.

Peak, Max or Dynamic Power Ratings:

No matter how you word it, this form of power rating refers to the maximum amount of power an electronic device can handle or output in an instant without damage. Often times this rating could be reached with a big bass hit or a very loud note in a song as it’s played using the correct amplifier. We do not recommend that you use the peak, max or dynamic power rating when configuring your system because it does not reflect the products capability under everyday use. So why then is this power rating still listed if it’s somewhat exaggerated and unreasonable? Manufactures still advertise peak power because most consumers are unaware of its meaning and believe that larger numbers are better. Peak power is used to make a product seem more powerful than it actually is, sometimes even five or six times more powerful than the RMS rating.

And there you have it. Play it safe and stick with RMS power ratings while staying away from peak, max or dynamic power listings.

Broadcast Capable w/Optional Amplifier & Plasma Tube
  • A master oscillator combined with a powerful amplifier is needed to use the gas filled tube radiant, or broadcasting, method of outputting frequencies. If you are wanting to use the more powerful, versatile 1930’s/1950’s radiant method, then this amplifier is the instrument you will want to own.

    – Power output of 207 watts peak power (103 RMS)

    – Ability to run from 1 to 8 frequencies (up to 40,000 hertz) through a gas filled tube. No other instrument has this capability. (Rife ran up to 10 at a time.)

    – Original vacuum tube gas filled plasma tube instrument with the ability to use a variable frequency from 1 to 20,000,000 million Hertz. It also has a variable built in carrier frequency which goes from about 2.2 to 3.8 MHz.

    – Uses the superior high voltage – low current design over the low voltage – high current design.

  • Hands free Operation / Run it While You Sleep Useful range is about 30 feet when using gas tube. However, due to the laws of physics there are limitations to gas filled tubes and metal antennas that need to be understood. Both are very efficient and about 100% of the energy that you put into them comes out. But for every foot that you move away from these antennas you lose 75% of the power they output. Example: With a 207 watt output, at one foot away from the gas filled tube you will get 51.75 watts. At two feet away you only have 12.93 watts, and at 3 feet you only have 3.23 watts. Because of the laws of physics it is important to be as close to the gas filled tube as you can get if you want the greatest amount of the energy that comes out of it. One to six feet distance away from the gas tube would be the best choice. Always the closer the better.

    Suggested range: 1 inch to 6 feet when using gas tube. Because there is no 1 foot to 3 foot null zone (non-effective range) it is not necessary to stay 3 to 6 feet away from the gas tube because it outputs the same as the 1930’s/1950’s equipment that was used within 6 inches of the target area.
