Frequently Asked Questions

Q: Does the GB-4000 output its frequencies digital or analog?

A: Analog.

Q: How does the GB-4000 output its frequencies analog when they come from a digital chip?

A: The GB-4000 uses a DAC (Digital to Analog Converter). This type of electronic circuit is used in all modern analog frequency generators. The frequencies are output from a DSP, (Digital Signal Processing) then go through the DAC and then through a low pass or band pass filter and come out converted to analog. By this method we have all the harmonic content of the old antique vacuum tube frequency generators along with the digital accuracy. No old antique frequency generator has the frequency accuracy of today’s modern equipment. We recommend that you read this page “The Analog Vs Digital Frequency Debate.”

Q: Can the GB-4000 output the original high RF or Radio Frequencies Dr. Rife used in the 1934 clinic?

A: Yes. The GB-4000 has a frequency range from .01 to 20 million hertz (20 Megahertz).

Q: Why do the instruments built today only use low audio frequencies when Dr. Rife’s original frequencies were much higher?

A: The FCC (Federal Communication Commission) is the 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 ray tube. The frequencies output through the ray tube would travel about 12 miles in each direction from his laboratory. Dr. Rife said his equipment would “raise the devil” with all the radios. In 1936 Dr. Rife’s engineer, Philip Hoyland built the first audio frequency instrument. From this time on Dr. Rife’s original high frequencies were no longer used in any of the equipment. This of course made it so his instrument was not as effective. In the 1950s Dr. Rife, John Crane and John Marsh continued to build this low audio frequency instrument. Today’s modern instruments were patterned after this low audio frequency instrument. I recommend that you read the Rife Report which you'll get as a free download when you register on this site.

Q: How can the GB-4000 output Rife’s original high frequencies and the other instruments cannot?

A: Pad type instruments do not use ray tubes. They use hand cylinders and foot pads that come in contact with the body. This makes it so the body becomes the antenna. The body is not a very efficient antenna so the frequencies do not broadcast far enough to interfere with radio stations. This means Rife’s original frequencies can again be used. The reason the GB-4000 can output Dr. Rife’s frequencies is the manufacturer invested the money to build it so these frequencies could be used. Other manufacturer could do the same thing if they were willing to invest the money into their instruments.

Q: Can modern “Ray Tube” instruments output Dr. Rife original high frequencies?

A: No. The FCC is the problem. Most of Dr. Rife’s original high frequencies are in the AM band of frequencies. The only frequencies that modern ray tube instruments can output are the low audio frequencies.

Q: Why does the GB4000 use a "RF Carrier Wave” with low audio frequencies?

A: The use of carrier frequency is the main difference between the GB-4000 and all other pad instruments. All of the ray tube instruments built from 1936 to the 1950s used an RF (Radio Frequency) carrier frequency with low audio frequencies. These instruments all used a 4.68 Megahertz carrier frequency and modulated or piggybacked the audio frequencies onto that carrier frequency. Low audio frequencies are like the human voice which cannot travel more than a short distance. A carrier frequency was used so that the frequencies could be broadcast through the air, by use of a ray tube, which made it so the frequencies could fully penetrate the body, including the bone. Without this carrier frequency the audio frequencies will not go through the cells of the body but only travel through the connective tissue of the body.

Q: What is the main difference between the GB-4000 and other “pad” instruments?

A: The GB-4000 uses an RF carrier frequency and the other instruments do not. The GB-4000 uses an RF carrier frequency with all audio frequencies. In 1936 when Dr. Rife’s engineer, Philip Hoyland, built the first audio frequency instrument it used a carrier frequency. The audio frequencies were modulated or piggybacked onto the carrier frequency. This makes it so that the audio frequencies can fully penetrate the body, including the bone. Without this carrier frequency the audio frequencies will not go through the cells of the body but only travel through the connective tissue of the body. (Click here to read the Bio-Electrical Impedance report on how frequencies work in the body)

Q: Some Manufactures of other instruments claim that “there is no safe level of radio frequency (RF) for the human tissue.” Is this true?

A: No. In order to prove this we will need to give you all the facts. Dr. Rife’s 1923 to 1935 frequency generating equipment consisted of the Colin B. Kennedy Models 110, 220 and 281. He used the Models 110 and 281 at the 1934 clinic. All the frequencies used at that 1934 clinic were only RF Frequencies. These frequencies from this earlier equipment didn’t need a carrier frequency because all the frequencies were RF frequencies. These frequencies ranged from 139,200 hertz for Anthrax to 1,604,000 hertz for the BX Cancer virus. Dr. Rife found that only these high RF frequencies would resonate and kill the organisms they are associated with. We do not understand how anyone could say that “there is no safe level of radio frequency (RF) for human tissue” when RF frequencies are all that Dr Rife used from 1923 to 1962 in his ray tube instruments. In order to show proof that RF is safe to use we need to quote Dr. Rife because it is his technology. In a letter sent to Dr. Stein in 1953 Dr. Rife made this statement:

RIFE: “I have operated the frequency instrument since 1921. I have watched it advance in style and performance with the advancement of electronics. In the many years I have used this equipment in my research, I have never suffered an injury or any ill effects whatsoever. I found it reliable in performance and efficient in results.”
On the John Marsh, Rife audio CDs Dr. Rife also made this statement about his RF frequency instrument:

RIFE: “I stood in front of that thing for thirty years finding these different frequencies that devitalize these different bacteria. And that thing [RF ray tube] was shooting on me right here [his chest], but it is absolutely harmless to normal tissue and each individual bacteria requiring a different frequency to devitalize.”
Here is another explanation that Dr. Rife gave on the John Marsh audio CDs of how the frequencies worked and how they were broadcast:

RIFE: “We take two tuning forks, pitched to an absolute C. We put one here, we put the other one over there. We strike this one, this one resonates. And we’re creating a frequency just the same as a broadcasting station [RF radio frequency] on the air throws out a given frequency for their particular band or wavelength that is susceptible and picked up through a receptive or receiver end of a radio.”

And here is my last statement made by Dr. Rife. There are several others but these I have quoted should be sufficient to prove the point beyond anyone’s doubt that Dr. Rife’s original equipment and frequencies were RF frequencies and were completely safe to use.

RIFE: “You know we had an idea when we had our Clinic [in 1934] in La Jolla, of course that was battery and motor generator operated that set, you know, and boy it would sure raise the devil with all the radios so we had a couple of cars that was equipped with car radios and we sent them out and we would take the switch of that thing, and had a code you know like an S.O.S., and one of them went up north, and one of them went south from La Jolla. Before we started in we wanted to see how far we were going to disturb things with it you know, and incidentally we had it in a steel room, a steel lined vault about this size at the old Ellen Scripp’s home. It was the vault in the library of the Scripp’s home where they kept their valuable manuscripts and books in all steel lined and a door on it like a safe. We had the thing inside of that too, but it didn’t make much difference, but we started in, and one car lost the pick up on top of Torry Pines, and the other one half ways through Mission Beach picked it up, and then they could go a hundred feet and lose and then they would have to pick it up again. Old Henry [Henry Siner] the boy that was with us out there, one of the lab boys, boy he went up in the air. He says, “By God” he says “look, we’re going to fix them up right. At two o’clock we’ll hook this up to a big radio station, a big transmitting station, and at two o’clock next week we’ll broadcast for tuberculosis, and at half past three the week after we will broadcast for cancer, and everybody at the radio will pick it up”. See, boy I said Henry that really is an idea.” (John Marsh Collection, Trip to Ohio Papers, Page 7, www.rife.org)

These statements of Dr. Rife’s show that these manufacturers know very little about RF and very little about the methods Dr. Rife used.

The statements quoted above show that Dr. Rife found that his RF frequencies in the ranges he used were as safe to use as the frequencies output by any radio station. These frequencies are broadcast through the air day and night passing through our homes without any harm to the human body. Dr. Rife used various power levels of RF energy. His instruments range from 8 watts, when he first began his work in 1920, to about 110 watts of power in 1935. Dr. Rife did mention, when he talked with Dr. B. Winter Gonin M.D. and John Crane, that power levels that exceeded about 110 watts he would not want to use on people.

Q: Some people claim that there are harmful frequencies. Is this true?

A: This question has both a Yes and No answer. Dr. Rife found no harmful frequencies below about 40 Megahertz (40 million cycles per second) when the proper power levels were used. All Rife type manufacturers do not use frequencies higher that 40 Megahertz. These manufacturers along with the GB-4000 always stay within safe frequency ranges.

Q: What is the highest frequency that the GB-4000 can output?

A: 20,000,000 Hertz (twenty million cycles per second).

Q: Most other manufactures only have a frequency range to 10,000 hertz. Some go up to 21,275 hertz. The GB-4000 goes to 20,000,000 hertz. Why?

A: Dr. Rife’s original high RF frequencies are in this higher frequency range. As pointed out earlier Dr. Rife found no harmful RF frequencies or their harmonics up to over 40 million hertz (40 Megahertz). The previous model to the GB-4000 was limited to 21,800 hertz modulated onto an RF carrier frequency. Four years ago we built the GB-4000 so it would have a top frequency of 20 million hertz. This made it possible to use all of Dr. Rife’s original high RF frequencies which he said would devitalize microorganisms. Below is a list of Dr. Rife’s high RF frequencies taken from his Kennedy equipment back in 1935.

Dr. Rife’s 1923 to 1935 Colin B. Kennedy equipment frequencies in Hertz

Actinomycosis (Streptothrix)	139,000
Anthrax	139,200
B. Coli (Rod form)	417,000

Q: Are the higher RF frequencies based on Dr. Rife's early work or on his later work with John Crane?

A: They are based on Dr. Rife’s earlier work from 1923 to 1935. The FCC (Federal Communication Commission) is the reason why Dr. Rife could no longer build his high RF frequency ray tube instruments. In 1935 Congress created the FCC and by 1936 they began to regulate the airwaves. Before 1935 there were no FCC regulations to prevent Dr. Rife from using his high RF frequencies broadcast through a ray tube. The frequencies output through the ray tube would travel about 12 miles in each direction from his laboratory. Dr. Rife said his Kennedy equipment would “raise the devil” with all the radios. In 1936 Dr. Rife’s engineer, Philip Hoyland, built the first low audio frequency instrument. From this time on Dr. Rife’s original high RF frequencies were no longer used in any of the equipment built. This of course made it so his instrument was not as effective. Dr. Rife at first thought Philip Hoyland was using his original high RF frequencies but later in the 1939 Beam Rays Trial Dr. Rife found out that Philip Hoyland had changed the machine and was using only low audio frequencies. Here is a quote from Dr. Rife showing how much he disliked Philip Hoyland’s design:

RIFE: “I spoke only Friday evening to a Mr. John Chamblin, a radio man now connected with Beam Rays Inc., about the redesign and building of a device according to the old Rife Ray principles; as the present instrument has been so deviated away from that old principle that it is nowhere near the same...those devices which you have are merely working on a harmonic and not a true frequency; and in our research on electronics, we definitely know that there is no possible way of controlling electrical harmonics of a frequency.” (Letter from Dr. Rife to Gonin dated May 14, 1939)

In the 1950s Dr. Rife, John Crane and John Marsh continued to build this low audio frequency instrument. The reason for this is that by 1940 Dr. Rife came to understand that the new FCC regulations made it so he could no longer build a ray tube instrument that would output his high RF frequencies. Because of these FCC regulations Dr. Rife had to put up with Philip Hoyland’s less effective design or no longer continue his work. Most of today’s modern instruments were patterned after these less effective low audio frequency instruments. As pointed out earlier most instruments built today do not use the RF carrier frequency used in these less effective low audio frequency instruments. Dr. Rife did not like the fact that John Crane and John Marsh did not use a carrier frequency in the pad instruments they built. When Bertrand Comparet, Dr. Rife’s attorney asked him about these instruments that did not use a carrier frequency Dr. Rife made this statement to him:

COMPARET: “And I asked Rife, because I thought Rife would certainly say that the way Crane was working on it then was still using the Rife principle, but he indignantly denied it.” (Comparet interview papers - 1970’s)

In the previously quoted statement, in which Dr. Rife thought that Henry Siner’s idea to broadcast the frequencies to heal people to be a good idea, shows that Dr. Rife had no problems using a metal antenna. Therefore John Cane and John Marsh’s idea of using pads was not the reason Dr. Rife disliked the pad instruments. It was the lack of an RF carrier frequency that Dr. Rife did not like.

It is apparent that Dr. Rife was not happy with this style of pad instrument that had no RF carrier frequency. Below is Dr. Rife’s statement of the full range of his frequencies. You will notice that he puts many of his frequencies in the broadcast band of frequencies. The AM band goes from about 500,000 hertz to 1,700,000 hertz. Dr. Rife’s original high RF frequencies went from 139,200 hertz for Anthrax to 1,604,000 hertz for the BX cancer virus. The GB-4000 can output all of this frequencies.

RIFE: “Some of them are in the visible band, or I mean not only the visible band but, uh, band of frequencies audible [audio] to the human ear. Some of them are way beyond either way. They run through a very, very large gamut. Some of them are very, very broad, long. Some of them are...not extremely short. There are none of them what we call our ultra short wave that I have found yet. Well there’s many of them...we would, uh, classify in the ultrasonic band because they’re not visible [sic] with the human ear. They’re way beyond you know. And some of them are even in the broadcast band. Your cancer is very high. You can’t hear it, the oscillation. But now you take your T.B. [Tuberculosis]. Now that’s down. A little more you see...if you don’t have an absolute coordinative resonance, you have nothing. One tenth of one meter off and you have nothing. It’s got to be absolutely correct for that individual organism. It’s got to be precise...the virus of cancer has a certain frequency. And it has to be there, otherwise if it’s a little one way or the other, no good, no good for nothing. Infrared will penetrate, yes, but the heat is not the thing because the heat is not the frequency, its [Infrared] way down in the very low band of frequencies and the laboratory rate of the BX is up into the high band.” (John Marsh Rife CDs - CD 5 track 2, CD 6 track 2, CD 7 track 1 and CD 9 track 1)

Anyone reading this can see that unless you have an instrument that can output all of Dr. Rife’s frequencies you are limited to only the audio frequencies. Dr. Rife said that you have to have the correct frequency in order to have a resonate effect that will kill or devitalize an organism. The BX and BY cancer frequency is 1,604,000 hertz and the low audio frequency that Philip Hoyland used in his audio frequency instrument is 20080 and 21275. By the 1950s Dr. Rife, John Crane and John Marsh lowered these frequencies even further to 2008 and 2128. Philip Hoyland’s higher audio frequencies were sine wave waveform and Dr. Rife, Crane and Marsh’s frequencies were changed to square wave waveform. This is how and when the square wave waveform was first used.

Below are both lists of the less effective low audio frequencies that are based on Philip Hoyland’s changes. Dr. Rife disliked these changes but later found that he had no choice but to use this method because of the FCC regulations. Before I give the frequency list I will quote a statement made by Dr. Rife, about Philip Hoyland’s changes, in a letter written on March 22, 1958:

RIFE: “Hoyland was like many men with whom I have associated over a period of years. In short time he began changing the basic principles of these instruments according to his own ideas.”

Q: I have heard that an instrument that uses impedance matching works better. Is this correct?

A: Yes. Impedance matching makes it so more energy can penetrate. Think of impedance as resistance. When the resistance is removed then more energy can flow in the direction you want it to go. This is why GB-4000 and its earlier models have all used impedance matching since 2000.

Q: How much more powerful is the GB-4000 than other non-RF “pad” instruments?

A: Because of the use of an RF carrier frequency the GB-4000 is over 9 times more powerful than other “pad” instruments. If the SR-4 amplifier is used with the GB-4000 it is over 50 times more powerful than other “pad” instruments that do not use a carrier frequency.

Q: Why do I need the optional Amplifier?

A: The GB-4000 can operate in two different modes. 1: RF, which is the higher frequency mode for greater tissue penetration and, 2: Audio, which is the lower frequency mode. Other contact or pad type instruments only have an Audio mode output. In RF mode, the GB-4000 has an output of about 2 watts, however, many researchers who are experimenting with issues such as Lyme disease want the maximum power available. The SR-4 Amplifier boosts the 2 watt RF output to about 10 watts of RF output. Also, the Amplifier gives three additional sets of outputs so more than one subject can use the instrument at the same time. The SR-4 10-Watt Amplifier operates in the RF mode only.

Q: Why was the GB-4000 built to output up to 8 frequencies simultaneously while other instruments only output one frequency at a time?

A: To save time for the person using it. Many programs have as many as 40 frequencies. If you run 8 frequencies one at a time for the standard 3 minute time period it would take you 24 minutes. With the GB-4000 it would only take you 3 minutes. That is quite a time savings for those who do not want to spend hours using an instrument.

Q: Did Dr. Rife ever run multiple frequencies?

A: Yes.

Q: Some manufacturers of other instruments claim that the use of more than one frequency at a time will cause too much conflict with the other frequencies and make it so none of the frequencies work. They also say that running multiple frequencies creates conflict with the meridians of the body.

A: I've seen no scientific proof that running more that one frequency at a time conflicts with the meridians of the body. Dr. Rife never found this to be the case.

Dr. Rife ran many frequencies at the same time and found that there were not enough conflicts to make it so the frequencies did not work. We will now quote Dr. Rife and give proof that he not only used many frequencies simultaneously but found that not only did they work but they worked very well. We will also show that Dr. Rife, John Crane and John Marsh were building an instrument in the 1950s that would output 10 frequencies at the same time in order to save the doctors using the equipment both time and money. Here is Dr. Rife’s statement:

RIFE: “We found the frequency of the virus, we found the frequency of the rod, which we had for years of course. But if we use the two of them simultaneously over the same carrier wave, the patient gets well and the Guinea pig gets well, but if you use one or either individually you either kill the patient or you don't do nothing". (Marsh collection, Rife audio CDs)

In Dr. Rife’s 1936 lab film, which is free for you to watch on this web site, Dr. Rife showed that he could run 5 frequencies simultaneously. Why would he demonstrate this capability if he had not tested it?

In a letter sent to Dr. Robert P. Stafford on November 14, 1959 John Crane told Dr. Stafford about the new instrument they were building that would run ten frequencies simultaneously:

CRANE: “We are building various pieces of test equipment for the new Frequency Instrument and as planned now – it will only have one switch to turn it off and on. Everything else will be accomplished internally – all frequencies will be crystal controlled with 10 frequencies riding the same carrier wave simultaneously. 100% modulation is our goal which is the point of maximum transmission of energy”. Click here to read the source of this quote

It was this documented information that you have just read and seen that caused us to build the GB-4000 so it could output up to 8 frequencies simultaneously. If we could have output more we would have but this was the limit of the processor that we used. As you can see, the reason other manufacturers claim that the frequencies will interfere with each other is because their instruments can only output one frequency at a time.

Q: Does the GB-4000 use codes or does it show the actual frequencies on the LCD?

A: The GB-4000 uses actual frequencies instead of limited coded frequency numbers. When you use codes for frequencies you limit the number of frequencies that your instrument can put out. With the use of actual frequencies the user is not limited to just the available frequencies. There are many frequencies listed on internet frequency lists that one may wish to use. At least half these frequencies on these frequency lists cannot be programmed into the instruments that use limited codes.

John Crane and John Marsh tried to hide the frequencies by just giving dial settings for the frequencies back in the 1950s. Philip Hoyland tried the same thing with the Beam Rays instrument built back in the1930s. The concept was later used by Kimberly Bailey back in about 1990 when she built a pad instrument. She did this to try and hide the frequencies from people who might try and steal her instrument technology. Since that time it has been continued until the present day. If people don’t mind this type of limited instrument then that is their choice. Most people do not want to be limited to a small number of pre-programmed frequencies and they also want to know the frequency they are using, not just a code.

Q: Why doesn’t the GB-4000 display the actual medical condition on the LCD?

A:The GB-4000 has almost the complete list of frequencies available on the web programmed into its memory. The person who purchases it or the distributors who sell it can make sure that they are programmed into it. These programs are matched to numbers given in a list of 871 conditions. The GB-4000 does not have the conditions programmed into it for legal reasons. It is against FTC and FDA regulations to do this. If we put the names of the conditions into our instrument this would constitute medical claims. This would then make our instrument a medical device. We do not want to violate any regulations or to be considered a medical device. Other manufacturers have had legal problems in the past because of medical claims and testimonials put on their websites. This is the reason the GB-4000 is sold as a 20 Megahertz Sweep Function Generator and not a Rife machine.

The Universal frequency list and manual that is used by the purchasers of the GB-4000 has medical definitions included in it. People want all the information they can get. This is too much information for the LCD screen to display. The final reason we do not put this information on the screen is a separate company builds and supplies the accessories such as the frequency manual, hand cylinders and foot pads. If we shipped this in the same box with our instrument it would also be considered medical claims. Herb manufacturers have had legal problems because they printed on the labels of their products what the herb could treat. The laws will not allow them to do this anymore because the government considers these to be medical claims. We do not desire to take any chances of having legal problems.

Q: I have been told that Dr. Rife used a ray tube, not pads. Is this correct?

A: Yes. Dr. Rife found that the method that he needed to use for his experiments on microorganisms was a ray tube. He did not need to have the ray tube but it made it easier to do his testing. He could have used metal wires but they will heat the test media to the point that the heat will kill the organism. The heating of the organisms would have made it three or four times harder to do his experiments. Dr. Rife was not against the use of a metal antenna because the ray tube is an antenna which uses noble gases. Here is a statement from Dr. Rife that shows that he felt using a metal antenna from a radio station would be a good method to use:

RIFE: “You know we had an idea when we had our Clinic [in 1934] in La Jolla, of course that was battery and motor generator operated that set, you know, and boy it would sure raise the devil with all the radios so we had a couple of cars that was equipped with car radios and we sent them out and we would take the switch of that thing, and had a code you know like an S.O.S., and one of them went up north, and one of them went south from La Jolla. Before we started in we wanted to see how far we were going to disturb things with it you know, and incidentally we had it in a steel room, a steel lined vault about this size at the old Ellen Scripp’s home. It was the vault in the library of the Scripp’s home where they kept their valuable manuscripts and books in all steel lined and a door on it like a safe. We had the thing inside of that too, but it didn’t make much difference, but we started in, and one car lost the pick up on top of Torry Pines, and the other one half ways through Mission Beach picked it up, and then they could go a hundred feet and lose and then they would have to pick it up again. Old Henry [Henry Siner] the boy that was with us out there, one of the lab boys, boy he went up in the air. He says, “By God” he says “look, we’re going to fix them up right. At two o’clock we’ll hook this up to a big radio station, a big transmitting station, and at two o’clock next week we’ll broadcast for tuberculosis, and at half past three the week after we will broadcast for cancer, and everybody at the radio will pick it up”. See, boy I said Henry that really is an idea.” (John Marsh Collection, Trip to Ohio Papers, Page 7, www.rife.org)

As you can see Dr. Rife felt that Henry Siner’s idea was a good one. Hand cylinders are stainless steel and when they come in contact with a person it turns the body of that person into an antenna. This is the method that is used with pad instruments.

Q: I have been told by manufacturers of various "Ray Tube" devices that "pad" instruments have "skin effect" where the frequencies do not penetrate the body but only go across the surface of the skin. Is this true?

A: No. If the human body was a copper wire this would be true, but it is not. The GB-4000 utilizes an RF (Radio Frequency) 2.4 MHz carrier frequency with the use of low audio frequencies. Scientific tests called “Bio-Electrical Impedance Analysis” have shown that frequencies of 1 Megahertz (1,000,000 cycles per second) or higher will penetrate bone and cells. This is one of the many reasons why GB-4000 uses a 2.4 MHz carrier frequency to modulate or piggyback the low audio frequencies on. This method of modulation makes it so the audio frequencies will penetrate the cells and bone of the body. Low audio frequencies when used without a carrier frequency only go through the connective tissue between the cells of the body. These scientific studies were done by many universities during the development of MRI machines. Click here for more on this topic

Since Ray Tube manufacturers have brought up this point we will discuss it a little further. There are two types of “Ray Tube” instruments. One type uses a carrier frequency and the other type does not. The type that does not use a carrier frequency is referred to as an EMEM. These work by using coils which create a very high electro-magnetic-field. They seem to work very well but no scientific tests have been done on this type of ray tube instrument to determine if it can fully penetrate the cells and bone of the body. Testing has shown that they do produce some RF components but this is not the same as an RF carrier frequency. Dr. Rife used an RF carrier frequency in all his audio ray tube instruments.

The other type of ray tube instrument does use a carrier frequency. These manufacturers also modulate the audio frequencies onto the carrier frequency. These RF ray tube instruments are patterned after the 1950’s ray tube instrument which was called the AZ-58. This instrument was built by Dr. Rife, John Crane and John Marsh. Like the GB-4000 these instruments, by the use of an RF carrier frequency, get full penetration of the audio frequencies into the cells of the body.

Q: What is the difference between the output of a contact or "pad" type instrument and the output of the RAY TUBE?

A: Contact or "pad" type instruments deliver frequencies through direct contact, while 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 ray tube is very efficient as long as you keep the ray tube within several inches of the body. 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. If you have 50 watts (power level used by Dr. Rife’s 1934 instrument) 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 Dr. Rife had the doctors who used the instruments 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.

With a direct contact instrument such as the GB-4000 we do not have this power loss problem; therefore, we do not need to use anywhere near the same power levels used by a ray tube instrument. The GB-4000 outputs about 2 watts. This is equal to a 50 watt ray tube instrument at just over 2 feet away from the ray tube. If the SR-4 10 watt amplifier is used this is equal to a 50 watt ray tube instrument at just over 1 foot away from the ray tube. This is the benefit of a contact instrument.

Q: When and why was the contact or pad instrument developed?

A: The first contact instrument was built in 1957 by John Crane and John Marsh. Photos of it are on this site. The ray tube instruments were very expensive to build and they wanted to build smaller instruments that would be less expensive. Even today many ray tube instruments are three times more expensive than pad instruments. John Crane and John Marsh took an off-the-shelf frequency generator and hooked up pads to it. These first pad instruments worked quite well but were underpowered like most of the pad instruments built today. They tried to overcome the power problem with larger pads. The mistake they made was they didn’t use an RF carrier frequency. Because the off-the-shelf generator didn’t have a carrier frequency they no longer used one. Without the RF carrier frequency they couldn’t get the same results as the ray tube instrument. This is the reason the GB-4000 uses a carrier frequency so that the power of a ray tube can be incorporated into a pad type instrument.

The power output of the pad instruments on the market today that do not use an RF carrier frequency is only about 0.20 of 1 watt. The GB-4000 with the use of an RF carrier is about 2 watts and is over 9 times more powerful than these instruments. With the use of the optional SR-4 amplifier it is over 50 times more powerful.

It appears that the reason that Dr. Rife did not like these non-RF carrier frequency pad instruments is because they were so badly underpowered that he felt they could not do the same job as a ray tube instrument. We showed earlier that Dr. Rife had no problems with the idea of using a metal antenna.

Q: Some manufacturers build there instruments with built in rechargeable batteries. Why doesn't’ the GB-4000 have this capability?

A: The reason the GB-4000 is not battery operated is because it is far more powerful than other instruments. Rechargeable instruments only have 28 volts peak to peak voltage output. The GB-4000 has two different modes. One is RF and the other is Audio mode. In the audio mode, which is the same square wave output as these other instruments the GB-4000 is 35 volts peak to peak. In the RF mode the GB-4000 is over a hundred volts peak to peak. These other instruments only output about 0.20 of one watt of power. The GB-4000 in RF mode has almost 2 watts output. This means the GB-4000 is over nine times more powerful than all other pad instruments. Because John Crane and John Marsh didn’t use an RF carrier frequency their instrument was so badly underpowered that it just didn’t work as well as the ray tube instrument. This is the reason Dr. Rife did not approve of John Crane and John Marsh’s pad instrument. When you use an RF carrier frequency you can increase the power of a pad instrument to the power of a ray tube. This is the greatest benefit of using Dr. Rife’s method of RF energy.

Because of what has just been explained it is not feasible to put batteries into the GB-4000. The whole case is filled with electronics and this is necessary so that we could manufacture an instrument that would have the capability to output all of Dr. Rife’s original RF frequencies, with power. Not just the low audio frequencies that other instruments output.

Q: Did Dr. Rife use gating and if he did, how does it work?

A: Gating is basically an advanced "pulsing" feature. It appears from all the information that we have that Dr. Rife instruments used some form of gating to produce the high potential spikes in the frequencies. The GB-4000 has the ability to gate any frequency. A square wave frequency works a lot like gating. Gating is the turning on and off of a frequency. A 50% duty cycle square wave is on for 50% of the time and off for 50% of the time. When using low square wave audio frequencies the gating feature is not that important but some people on the various Rife lists believe it is helpful even when using these low audio frequencies. The GB-4000 allows you to turn the gating on or off and to adjust the gating frequency (5 Hz to 2200 Hz) and duty cycle (10% to 90%) of the gate. Many frequency researchers feel that this gating, or pulsing feature greatly adds to the effectiveness of the technology. Gating is also believed to induce the effect of entrainment which is defined as "the tendency for two oscillating bodies to lock into phase so that they vibrate in harmony.

Dr. Rife used high sine wave RF frequencies in his instrument. Gating of these high frequencies produces a high potential voltage spike with a great deal of harmonics much like a square wave. Since square wave has worked better than sine wave it only stands to reason that gating would be very effective when using Dr. Rife’s high RF frequencies. This is the main purpose of gating.

Q: Why does the GB-4000 have a 10% to 90% duty cycle when other instruments only use a 50% duty cycle.

A: The reason that a 50% duty cycle was used by Dr. Rife, John Crane and John Marsh is this circuit was easy to build. Back in the 1950s when Crane and Marsh took an off-the-shelf function generator and created their first pad machine this instrument only had the capability to use a 50% duty cycle. The ray tube instrument also only used a 50% duty cycle. A 50% duty cycle means that the frequency is ON 50% of the time and OFF 50% of the time. The GB-4000, like other high end frequency generators, was built with the capability to use lower or higher duty cycles because all top end frequency generators have this capability. Many people were reporting on the Rife lists that they got better results using a 90% duty cycle on the low audio frequencies. A 90% duty cycle has 80% more resonance than a 50% duty cycle. Coordinative resonance was the basis of Dr. Rife’s life work. Why should a person be limited to only a 50% duty cycle when you can have one that is variable? We believe in having more features not less.

Q: Can the GB-4000 sweep between frequencies?

A: One of the great features of the GB-4000 is that it is capable of doing two kinds of sweep functions. 1) SWEEP: Allows you to run a specified frequency range of your choosing, one frequency at a time. The instrument sweeps from your beginning frequency to your ending frequency. 2) CONVERGENCE SWEEP: Allows you to run two frequencies at a time over a specified frequency range of your choosing. The instrument sweeps from your beginning frequency to the ending frequency and at the same time sweeps from the ending frequency to the beginning frequency. The result is that the two frequencies sweep towards each other, then pass each other, one going up and the other going down and each ending where the other frequency began.

Q: I heard that sweeping frequencies does not work as you need to run the frequency for several minutes on a specific frequency to destroy an organism?

A: This is not correct. Dr. Rife did a great deal of sweeping with his instruments. Written on one of Dr. Rife’s August 1935 lab notes is the information that shows that he was sweeping his frequencies and that sweeping was considered an important part of his testing.

Aug 17 mice rayed with MOR-BX 3 min last 30 seconds variable.

Aug 18 rayed all three mice with MOR-BX at 4 min at 16cm 30 sec variable.

Aug 27 all three mice rayed for BX with new machine #4, 600 watts 1 min 300 watts 2 min 1 min variable. ________

This lab note clearly shows that Dr. Rife was sweeping his frequencies. The 1936 to 1939 Beam Rays instruments also had a sweep switch on the front of the instrument.

Below this switch was a label that said “sweep.”________ Sweeping is only on a frequency for a fraction of a second if you are sweeping over a large frequency range. The GB-4000 has two kinds of sweeps. The regular sweep can go over any range from small to large.

Q: Why does the GB-4000 have a channel sweep capability which varies the frequency slightly.

A: The GB-4000 has the capability to sweep when running any of the 871 pre-programmed auto channels. The channel sweep only covers an 11 hertz sweep. If you run the instrument for only three minutes then it would be on each frequency for 16 seconds. Dr. Robert P. Stafford M.D. said that they did not get as good as results if they tried to keep the frequency right on. He had better results allowing the frequency to wander or sweep over several hertz during the treatment of his patients. Because of this information the channel sweep capability is a nice feature to have in an instrument.

Q: Why do you use a membrane type keypad instead of the contact style.

A: Durability is the main reason. Membrane keypad switches are the industry standard and have been for many years. Almost all electronic devices that have keypads use them. They are built to last for many years. They replaced the contact style because they have fewer problems. They will generally outlast the electronics. We have had this type of keypad on our instrument for over 8 years under heavy use without any problems.

Q: How long will the GB-4000 last?

A: The GB-4000 is built to last a long time and 99.9 % of the instruments sold over the last several years are still working. Some manufactures claim that there instrument will last a lifetime. We cannot and will not make that kind of misleading claim. We would be foolish to make such a claim. Any instrument that cannot be repaired, even after years of use, is replaced with the current model for only $650. No other company that I know of offers this kind of replacement in the industry.

Q: Is the GB-4000 easy to use?

A: Yes. To run a program all that the user has to do is press the Auto channel button, then enter the auto channel number using the keypad, then press the Run button. The GB-4000 then will run all the frequencies in the channel. Anyone can do this three step process.

Q: Why does the GB-4000 cost less than almost all the other instruments when it has far more features?

A: Most people are familiar with multilevel companies. The more levels the higher the cost.  We purchase direct from the manufacturer. There are no middlemen to make it more expensive.

Q: Where can I find updated research frequencies?

A: There are a number of resources on the internet for updated experimental frequencies.

Q: How much more powerful is the GB-4000 than other non-RF “pad” instruments?

A: Because of the use of an RF carrier frequency the GB-4000 is over 9 times more powerful than other “pad” instruments. If the SR-4 amplifier is used with the GB-4000 it is over 50 times more powerful than other “pad” instruments that do not use a carrier frequency.

Q: Why do I need the optional Amplifier?

A: The GB-4000 can operate in two different modes. 1: RF, which is the higher frequency mode for greater tissue penetration and, 2: Audio, which is the lower frequency mode. Other contact or pad type instruments only have an Audio mode output. In RF mode, the GB-4000 has an output of about 2 watts, however, many researchers who are experimenting with issues such as Lyme disease want the maximum power available. The SR-4 Amplifier boosts the 2 watt RF output to about 10 watts of RF output. Also, the Amplifier gives three additional sets of outputs so more than one subject can use the instrument at the same time. The SR-4 10-Watt Amplifier operates in the RF mode only.

Q: Why was the GB-4000 built to output up to 8 frequencies simultaneously while other instruments only output one frequency at a time?

A: To save time for the person using it. Many programs have as many as 40 frequencies. If you run these one at a time at 3 minutes for each frequency it would take two hours to run all 40 frequencies. With the GB-4000 running 8 frequencies simultaneously it will take you only 15 minutes. Most people do not want to waste their time. 

Q: Some manufacturers of other instruments claim that the use of more than one frequency at a time will cause too much conflict with the other frequencies and make it so none of the frequencies work.

A: This is not correct. Dr. Rife ran more that one frequency at a time. Here is his statement about running multiple frequencies at the same time:

RIFE: “We found the frequency of the virus, we found the frequency of the rod, which we had for years of course. But if we use the two of them simultaneously over the same carrier wave, the patient gets well and the Guinea pig gets well, but if you use one or either individually you either kill the patient or you don't do nothing". (Marsh collection, Rife audio CDs) 

In Dr. Rife’s 1936 lab film, which is free for you to watch on this web site, Dr. Rife showed that he could run 5 frequencies simultaneously. By the late 1950s Dr. Rife, John Crane and John Marsh were building an instrument that would have the ability to output 10 frequencies simultaneously. In a letter sent to Dr. Robert P. Stafford on November 14, 1959 John Crane told him about the new instrument:

Crane: “We are building various pieces of test equipment for the new Frequency Instrument and as planned now – it will only have one switch to turn it off and on. Everything else will be accomplished internally – all frequencies will be crystal controlled with 10 frequencies riding the same carrier wave simultaneously. 100% modulation is our goal which is the point of maximum transmission of energy”. (Click here to read this document. The last paragraph has this quote)

As you can see, the reason other manufacturers claim that the frequencies will interfere with each other is because their instruments can only output one frequency at a time.

Q: I have been told that Dr. Rife used a ray tube, not pads. Is this correct?

A: Yes. Dr. Rife found that the method that he needed to use for his experiments on microorganisms was a ray tube. He did not need to have the ray tube but it made it easier to do his testing. He could have used metal wires but they will heat the test media to the point that the heat will kill the organism. The heating of the organisms would have made it three or four times harder to do his experiments. Dr. Rife was not against the use of a metal antenna because the ray tube is an antenna which uses noble gases. Here is a statement from Dr. Rife that shows that he felt using a metal antenna from a radio station would be a good method to use:

RIFE: “You know we had an idea when we had our Clinic [in 1934] in La Jolla, of course that was battery and motor generator operated that set, you know, and boy it would sure raise the devil with all the radios so we had a couple of cars that was equipped with car radios and we sent them out and we would take the switch of that thing, and had a code you know like an S.O.S., and one of them went up north, and one of them went south from La Jolla. Before we started in we wanted to see how far we were going to disturb things with it you know, and incidentally we had it in a steel room, a steel lined vault about this size at the old Ellen Scripp’s home. It was the vault in the library of the Scripp’s home where they kept their valuable manuscripts and books in all steel lined and a door on it like a safe. We had the thing inside of that too, but it didn’t make much difference, but we started in, and one car lost the pick up on top of Torry Pines, and the other one half ways through Mission Beach picked it up, and then they could go a hundred feet and lose and then they would have to pick it up again. Old Henry [Henry Siner] the boy that was with us out there, one of the lab boys, boy he went up in the air. He says, “By God” he says “look, we’re going to fix them up right. At two o’clock we’ll hook this up to a big radio station, a big transmitting station, and at two o’clock next week we’ll broadcast for tuberculosis, and at half past three the week after we will broadcast for cancer, and everybody at the radio will pick it up”. See, boy I said Henry that really is an idea.” (John Marsh Collection, Trip to Ohio Papers, Page 7, www.rife.org)

As you can see Dr. Rife felt that Henry Siner’s idea was a good one. Hand cylinders are stainless steel and when they come in contact with a person it turns the body of that person into an antenna. This is the method that is used with pad instruments.

Q: I have been told by manufacturers of various "Ray Tube" devices that "pad" instruments have "skin effect" where the frequencies do not penetrate the body but only go across the surface of the skin. Is this true?

A: No. If the human body was a copper wire this would be true, but it is not. The GB-4000 utilizes an RF (Radio Frequency) 2.4 MHz carrier frequency with the use of low audio frequencies. Scientific tests called “Bio-Electrical Impedance Analysis” have shown that frequencies of 1 Megahertz (1,000,000 cycles per second) or higher will penetrate bone and cells. This is one of the many reasons why GB-4000 uses a 2.4 MHz carrier frequency to modulate or piggyback the low audio frequencies on. This method of modulation makes it so the audio frequencies will penetrate the cells and bone of the body. Low audio frequencies when used without a carrier frequency only go through the connective tissue between the cells of the body. These scientific studies were done by many universities during the development of MRI machines. (Click here to read one such report).

Since Ray Tube manufacturers have brought up this point we will discuss it a little further. There are two types of “Ray Tube” instruments. One type uses a carrier frequency and the other type does not. The type that does not use a carrier frequency is referred to as an EMEM. These work by using coils which create a very high electro-magnetic-field. They seem to work very well but no scientific tests have been done on this type of ray tube instrument to determine if it can fully penetrate the cells and bone of the body. Testing has shown that they do produce some RF components but this is not the same as an RF carrier frequency. Dr. Rife used an RF carrier frequency in all his audio ray tube instruments.

The other type of ray tube instrument does use a carrier frequency. These manufacturers also modulate the audio frequencies onto the carrier frequency. These RF ray tube instruments are patterned after the 1950’s ray tube instrument which was called the AZ-58. This instrument was built by Dr. Rife, John Crane and John Marsh. Like the GB-4000 these instruments, by the use of an RF carrier frequency, get full penetration of the audio frequencies into the cells of the body.

We showed earlier that Dr. Rife had no problems with the idea of using a metal antenna. 

Q: What is gating?

A: Gating is basically an advanced "pulsing" feature. This gating also causes very high harmonics in the carrier frequency or in a high RF frequency which may be used. The GB-4000 allows you to turn the gating on or off and to adjust the gating frequency (5 Hz to 2200 Hz) and duty cycle (10% to 90%). Many frequency researchers feel that this gating, or pulsing feature greatly adds to the effectiveness of the technology. Gating is also believed to induce the effect of entrainment which is defined as "the tendency for two oscillating bodies to lock into phase so that they vibrate in harmony.

Q: Why would I want to change the duty cycle?

A: Other frequency instruments are limited to a 50% duty cycle which means that the frequency is ON 50% of the time and OFF 50% of the time. The GB-4000 duty cycle can be changed from 10% to 90%. Many advanced researchers feel that there are huge benefits in applying frequencies in higher duty cycles because a 90% duty cycle has 80% more resonance. Coordinative resonance is the whole basis of Dr. Rife’s work.

Q: Can the GB-4000 sweep between frequencies?

A: One of the great features of the GB-4000 is that it is capable of doing two kinds of sweep functions. 1) SWEEP: Allows you to run a specified frequency range of your choosing, one frequency at a time.
