Frequently Asked Questions

One of the most common questions that I get all the time is about the difference between Analog and Digital frequencies. You may be wondering if a typical frequency generator generates analog or digital frequencies?

While frequency generators today often use digital circuitry the actual output is in fact analog. They use what is called a digital to analog converter (DAC) before the final output which changes a digital signal to an analog signal.

Of course tube technology is necessary for a purely analog circuit but with the availability issue of various tubes and the excessive cost engineering a purely tube based frequency generator is quite costly, and arguably unnecessary. There are certain benefits of tube technology such as the ability to withstand an EMP (electro-magnetic pulse, high tech warfare) making it a good choice for defense technology but otherwise a hybrid or digital circuit is usually a more economical and practical choice.

With the modern digital method the frequencies are output from a DSP, (Digital Signal Processor) then go through the DAC and then through a low pass or band pass filter and come out converted to analog. By this method you get 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.

Can a modern frequency generator cover the High RF Frequencies that Royal Rife was using in the 1934 clinic?

Truth is there's nothing really that special about these frequencies. They weren't 'scalar' waves or anything complicated like that so any frequency generator with a range above 17 million cycles per second (MHz) will cover that range that Rife was working in. If a frequency generator can't go this high it won't cover it.

You might also be wondering where all these lower frequencies that the Rife community talks about came from?

Actually, back in the late 1930's AM radio was becoming a big phenomenon. Evening talk radio was the 'talk of the town' (sorry for the bad pun) so much that the FCC banned the use of electrotherapy machines from the hours of 7pm to 11pm. This wasn't just Rife's technology but electrotherapy machines that were causing interference with evening talk radio on the AM band were actually commonplace in this era.

As the FCC began the ban of using RF frequencies due to interference Rife seemed to be faced with a decision to either find other frequencies which weren't going to interfere with AM radio or simply give up on the whole thing.

The frequencies output through the ray tube of the original instruments 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 especially once the RF carrier was dropped to bring down the cost.

Royal Rife was experimenting with audio frequencies which were piggy-backed on a higher frequency RF carrier wave in the 1940's. It doesn't seem like a coincidence that his engineer after the demise of the Beam Rays Corporation (the Phillip Hoyland partnership) the engineer that he worked with was also a police radio repairman. This engineer's name was Verne Thompson.

With Verne's assitance Rife worked to convert some of the old purely RF machines (some of which may have been originally manufactured by the Beam Rays Corporation) into Audio generators which were running audio frequencies through an RF carrier wave.

Where these audio frequencies actually came from originally is still somewhat of a mystery but it seems to pre-date Rife's work with John Crane. This definitely contradicts the widely held notion that John Crane had come up with these frequencies in the 1950's during the Life Labs era.

In the 1950s Dr. Rife, John Crane and John Marsh continued to build these low audio frequency instruments. This is when the RF carrier (higher frequency piggy-back) was dropped to bring costs down. Most of today’s modern instruments were patterned after these low audio frequency instruments which lacked the higher frequency RF carrier.

There are a few however which have brought back the RF carrier so these might be the gems to look out for when deciding to invest in a machine.

Next I'll be exploring rife frequencies and the frequency range of modern frequency generators.
