A Rife machine is a signal generator that sends chosen frequencies through electrodes or a plasma tube. No reliable study shows that it cures any disease. A complete Spooky2 starter kit cost 345.69 dollars and a GB4000 generator 1,975 dollars on 11 October 2026. ResoField is free browser software for Rife frequency lists and creates no physical signal.
A Rife machine is an electronic frequency generator that sends a series of chosen frequencies, measured in hertz, into the body through hand electrodes, footplates or a glowing plasma tube. It is named after Royal Raymond Rife, an American inventor who claimed in the 1930s that every microbe can be destroyed by its own frequency. That claim was never confirmed, and Cancer Research UK states that there is no reliable evidence that a Rife machine cures cancer.
People also call it a Rife frequency machine, a Rife device or a Rife generator. They all mean the same kind of equipment.
My wife and I started working with Rife frequencies after years of using the QEST4 for bioresonance. What surprised us was the overlap. Many of the frequencies on the Rife lists also turned up in our existing protocols, just sorted differently. That made me curious about where the lists come from, and what is actually known about them.
Who was Royal Raymond Rife?
Royal Raymond Rife was born on 16 May 1888 in Elkhorn, Nebraska, and worked for most of his life in San Diego. He built his own optical microscopes and in the 1930s made time lapse films of microbes. He claimed his microscopes reached magnifications of 17,000 times or more.
His central idea was the "mortal oscillatory rate". Every pathogen, he said, has a frequency at which it vibrates apart, just as a wine glass can shatter at the right note. He built what he called a beam ray device to send those frequencies by radio waves. According to his own account it could "devitalize disease organisms", with certain exceptions. Rife himself did not claim to cure cancer.
His findings were never independently confirmed, and some of his observations contradict what later microbiology found. Rife blamed the American Medical Association and organised medicine for the rejection of his work. He died penniless on 5 August 1971 in El Cajon, California.
The modern Rife machine really starts in 1987. That year Barry Lynes published The Cancer Cure That Worked, a book claiming that Rife had cured cancer and that his work was suppressed. The American Cancer Society called those claims implausible, but the book set off a wave of devices sold under Rife's name.
How does a Rife frequency machine work?
Every Rife machine has the same core: a signal generator that produces electrical frequencies. A program or a frequency list tells it which frequencies to run, for how long, and in what order. A typical session runs through a set of frequencies for a few minutes each.
The theory behind it is resonance. Supporters believe that pathogens and tissues each respond to their own frequencies, so a matching signal could disrupt a microbe or support tissue. That is the idea. It is not established biology.
The frequency numbers come from community lists. The best known is the Consolidated Annotated Frequency List (CAFL), a collection of frequencies with notes from users and older sources. Most Rife programs, hardware and software alike, draw on lists like this.
Contact, plasma and remote output
How the signal reaches the person depends on the device:
- Contact. You hold metal cylinders or rest your feet on footplates, and a weak current passes through the body. This is the most common method for home devices.
- Plasma tube. An amplifier drives a gas filled glass tube that lights up and gives off the signal without body contact. The GB-4000 with its MOPA amplifier is an example. Plasma setups are the most expensive.
- Remote. Some systems, Spooky2 among them, offer a remote mode that works with a sample from the person instead of electrodes. There is no accepted physical explanation for how that would work.
Most current systems connect a hardware generator to software on a Windows PC, which stores the frequency programs and handles timing.
Rife machine or zapper?
A zapper is sometimes sold as a cheap Rife machine, but the two work differently. The Hulda Clark zapper pulses one fixed frequency through the body, while a Rife machine runs through lists of specific frequencies. I wrote a separate article about the Hulda Clark zapper and how it compares to a Rife machine and bioresonance.
Types of Rife devices
Roughly speaking, you will find four kinds on the market:
- Computer controlled generators. Small generators that you connect to a PC. Spooky2 is the best known. Its software is free, but you need its hardware for any output. I compared it with other options in Spooky2 alternatives and free Rife software.
- Standalone generators. Devices with their own keypad and display, such as the GB4000. It stores 2,000 channels, and the seller gives a range of 1 Hz to 20 MHz.
- Plasma systems. A generator plus amplifier and plasma tube, the top of the price range.
- Software without hardware. Browser or app tools that manage frequency lists, protocols and client records. They produce no electrical signal. ResoField belongs here.

With the GB4000, the accessory kit (155 dollars) and the plasma tube for the MOPA (390 dollars) are sold separately. Most Spooky2 setups also need a Windows computer. Prices change, so check the seller's page before you buy. For the full picture, see Spooky2 vs ResoField and GB-4000 vs ResoField.
Do Rife machines work? What the research says
Here I want to be plain. A Rife machine does what it says on the box in one sense: it produces measurable frequencies. Whether those frequencies do anything to microbes or disease in the body is another matter, and there the evidence is thin.
- Cancer Research UK states that there is no reliable evidence that the Rife machine works as a cure for cancer, and that it has not been through the usual process of scientific testing. It mentions one small study in advanced liver cancer with a low energy device, but notes that the frequencies used there were not the same as those of Rife machines.
- In 1994 the American Cancer Society reviewed Rife devices and similar equipment in Questionable methods of cancer management: electronic devices.
- Rife machines are not FDA registered as medical devices. In the United States sellers have been convicted of health fraud, in 1996 and again in 2009, when James Folsom was found guilty on 26 felony counts.
Much of what you read about results comes from personal stories. Those matter to the people telling them, but they are not proof. In our practice we treat Rife frequencies as a complementary method, alongside and never instead of a doctor.
Is a Rife machine safe?
Supporters often say there are no side effects. Cancer Research UK mentions reports of electric shocks and skin rashes. The bigger risk is indirect: someone who postpones or stops proven treatment for an unproven one can seriously harm their health. If you have a medical condition, talk to your doctor first.
A software alternative: ResoField
Not everyone who searches for a Rife machine wants a box with electrodes. Many practitioners mainly want the frequency lists, a way to build protocols, and records of who received what.
That is the part ResoField covers. It is a free browser platform with an integrated RIFE frequency library, your own custom frequencies, protocols, client records and what we call quantum broadcasting. It runs on any computer, tablet or phone without installation.
To be clear about the difference: ResoField produces no current, no plasma and no other physical signal. If you want the physical output of a contact or plasma generator, you need hardware. If you want to work with Rife frequency lists in a clear digital workflow, the software is enough. How ResoField works shows the workflow step by step.

FAQ
What is a Rife machine?
A Rife machine is a frequency generator that sends chosen frequencies into the body through hand electrodes, footplates or a plasma tube. It is named after Royal Raymond Rife, who claimed in the 1930s that each microbe has a frequency that destroys it. That claim has never been confirmed.
Who invented the Rife machine?
Royal Raymond Rife (1888 to 1971), an American inventor and microscope builder from San Diego. He built a beam ray device in the 1930s. The devices sold as Rife machines today date mostly from after 1987 and use modern electronics.
How does a Rife machine work?
A signal generator runs through a list of frequencies, a few minutes each. The signal reaches the body through metal electrodes with a weak current, or through a plasma tube without contact. The theory is that matching frequencies disrupt pathogens through resonance, but research has not shown this.
Do Rife machines really work?
They produce measurable frequencies, but there is no reliable evidence that they cure disease. Cancer Research UK states that there is no reliable evidence that the Rife machine works as a cure for cancer. Use a Rife machine at most as a complement, never as a replacement for medical treatment.
How much does a Rife machine cost?
On 11 October 2026 the Spooky2 starter kit cost 345.69 dollars and the GB4000 generator 1,975 dollars. Plasma setups such as the GB4000 M.O.P.A. Combo Pack cost 4,870 dollars. ResoField, which works with Rife frequency lists in the browser but produces no physical signal, is free.
What is the difference between a Rife machine and a zapper?
A Hulda Clark zapper pulses one fixed frequency through the body. A Rife machine runs through lists of specific frequencies. Neither has been shown in controlled studies to cure disease.
What is the difference between a Rife machine and bioresonance?
A Rife machine sends fixed frequencies from lists such as the CAFL. Bioresonance devices such as the Bicom claim to read the body's own signals first and then send back a modified signal. Some modern devices combine both approaches.
Can I use a Rife machine app instead of hardware?
An app can take over the work around a Rife session: finding frequencies, building protocols, linking them to a client and keeping records. It does not reproduce the physical output of a generator. ResoField offers these tools free in any browser.
