Broadcast Capable w/Optional Amplifier & Plasma Tube!
  A master oscillator combined with a powerful amplifier is needed to use the gas filled tube method of broadcasting the 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:   190 watts

- Ability to run up to 8 Audio 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.)

- Ability to run 2 Radio frequencies (40,001 hertz up to 20,000,000) through a gas filled tube.

- Original plasma gas filled vacuum tube 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 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 47.5 watts.  At two feet away you only have 11.85 watts, and at 3 feet you only have 2.97 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 three feet distance away from the gas tube would be the best choice for maximum results.  Closer the better.

Suggested range: 1 inch to 3 feet. Because there is NO 1 foot to 3 foot 'null zone' (non-effective range, as some manufacturers state!) 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.



Why Power Output Is Important In A Frequency Generator

When comparing the various instruments, power output is a very important consideration.   More power means better signal strength, which in turns means deeper penetration along with a better quality wave. 

The power output of most frequency generators on the market today that do not use an RF carrier frequency is about 0.20  (1/5th) of a watt.    With the use of the RF carrier frequency, 4.7 watts is almost 25 times more powerful than these instruments. With the use of the optional 15 watt RF amplifier, it is 75 times more powerful!

Power and Running Multiple frequencies

Back in the 1950's Dr. Rife built a ray tube instrument that would run 10 frequencies simultaneously. So running multiple frequencies is not new!  Yet today there are some unknowledgeable people who want to disparage running multiple frequencies.  Successfully running multiple frequencies is directly tied to power.  If you have enough power then it IS  possible to do this.

Does running multiple frequencies reduce the power level of the frequencies?

The answer to that question would normally be yes... if you did not increase power levels.  This is why this generator was built to output 4.7 watts using a RF (Radio Frequency) carrier wave. Using the RF carrier frequency is the only way the power level could be increased. The original 1950’s equipment did not use an RF carrier frequency, so they could only output one audio frequency at a time with only 1/5th of one watt of power (0.20 of one watt). This power level worked well with only one audio frequency at a time.   In order to overcome this limitation, our 20Mhz generator uses two separate circuits.

The Audio Mode circuit has no RF carrier frequency and 0.75 watts power output.  It is used for frequencies from 1 Hertz to 400,000 Hertz. MANY frequencies used with this Audio Mode circuit can be physically felt from 1 to about 20,000 Hertz.  (electrical 'ticking' sensation)

The RF Mode circuit is used for frequencies from 1 Hertz to 20 million Hertz. The 3.1 MHz carrier frequency is also driven  with this circuit. When using the RF carrier, audio frequencies can not be felt.  By using this method, it is possible to use 4.7 watts (15 with the amplifier) and makes it possible to run up to 8 frequencies simultaneously.

Logically, if you use 2 audio frequencies you would want to double that power level to 0.40 of one watt.  (2 X 0.20 = 0.40 of one watt)    If you run up to 8 audio frequencies you would want at least 8 times that power level or 1.60 watts peak power. This is why our generator has 4.7 watts of power... so that it has over 3 times the power capability needed for running 8 audio frequencies simultaneously at the original 1950’s capability of 0.20 watts of power for one audio frequency.

Some people also ask if they can ONLY run multiple frequencies. The answer to that question is NO. This generator gives you the flexibility to switch from running one audio frequency at a time, to being able to run up to 8 audio frequencies at a time. You can choose how you want to run the frequencies.

Many people want even more power!   If you want even more power then you can purchase the optional 15 watt amplifier!

What separates our frequency generator from others available today?

First, the time saving feature. While almost all manufacturers only run one frequency at a time, this generator can run from 1 to 8 frequencies simultaneously. The benefit of running frequencies simultaneously is it SAVES A LOT OF TIME.    The industry standard 'Run Time' per frequency is 5 minutes.  So... If you run 1 frequency at a time, then 8 frequencies would take 40 minutes to run.  But if you run those 8 frequencies simultaneously, then it would only take 5 minutes to run all 8 frequencies.

This generator can output up to 8 frequencies simultaneously up to 40,000 Hertz (Audio Mode only), and 2 frequencies up to 20,000,000 Hertz (RF Mode).  Each frequency is generated and output in a pure waveform. With its 20 MHz frequency range, it has the ability to generate millions of individual frequencies in pure waveforms.

Some manufacturers claim that running multiple frequencies simultaneously causes the purity of each individual waveform to be lost, as well as creating the possibility of canceling out or creating other frequencies.  In order for a frequency to be canceled out, the same frequency must be introduced 180 degrees out of phase. Since  this generator does not output the same frequency 180 degrees out of phase, the canceling of a frequency is not possible.  (side note:  this is how scalar waves are produced)

Even though frequencies combined together may seem to lose their individual clarity, all the components of each frequency are present. Think of an orchestra playing many different instruments. Though they combine together to make beautiful music, each instrument’s full sound components are still present and nothing is lost.

Very rarely are other frequencies created, and when they are, they are generally beat frequencies, which are considered beneficial.

Second, the use of the 3.1 Mhz RF carrier wave frequency provides better penetration through tissue, while at the same time generates 1000's of sidebands harmonics.  (RF = Radio Frequency)  This is a DESIRED effect.  By Rife's and Hoyland's own admission, they weren't positive whether is was the base frequency being run, or possibly one of the sideband frequencies that was doing the trick.  It is almost always best to use the carrier.  However, you can turn it off with the press of a button if you want to try it both ways.  With no RF, you have a very basic device like most on the market.



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 shows that more power and more cycles per second (higher frequency), allow the signal to penetrate more deeply.  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)

In 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 desired & generated.  (above 40,000Hz)


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


Sample Sine Wave


Sample Square Wave

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


Signal sharply turns on and off. Can vary the rate of this "on/off" signal.  (Note:our device now can produce square waves to 400,000 Hz)


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 a more natural frequency.  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. 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 Pad type instrument vs. Ray Tube?

Contact instruments deliver frequencies through direct contact, 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.  Indirect contact though a plasma tube (broadcast method) is efficient also, but a bit more time consuming and cumbersome, as ray tubes should be held within several inches of the body.  The tube is waved over the entire body or target very slowly, or you sit very close to a stationary light tube. 

Many people believe that you can simply sit in the same room with one of these plasma ray tubes to get the full effect... this is  incorrect! The laws of physics in regards to signal loss come into play when using a ray tube.  It requires much more power at the frequencies 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.  (Our MOPA outputs 190 watts).  Some manufacturers recommend those who use them to stay at least 3 feet away from the ray tube, due to some notion of a "null zone", which DOES NOT EXIST with a true gas filled lamp.    In fact, JUST THE OPPOSITE IS TRUE!  (this industry is a minefield of misinformation!)  Stay within 3 feet for best signal strength! 

With a direct contact instrument, this power loss is not a problem. Direct contact also requires much less power, as the body is essentially the 'antenna' pulling in the signal.  Both methods have their benefits.
