Dr. Rife's machine covered a larger frequency range from the low audio frequency range of 12,000 Hertz to about 20,000,000 Hertz (20 million) or cycles per second. Dr. Rife used the available equipment or technology of his day in his instruments. The instrument Dr. Rife used in the 1934 clinic was assembled from standard off-the-shelf frequency generating equipment. In 1923 Dr. Rife purchased the Colin B. Kennedy Company equipment. Dr. Rife used the Kennedy Model 110, 220 and 281 in his work on microoganisms. The Model 110 had the broadest frequency range of these three models. It went from 12,000 Hertz to about 2 million Hertz. The frequencies that Dr. Rife used with the Kennedy equipment ranged from 139,200 Hertz for Anthrax to 1,604,000 (adjusted to 1,607,450 Hertz in 1936) for the BX cancer virus.
The audio frequencies that were used by Dr. Rife’s machines from 1936 through the 1950's were never intended to treat disease. The audio frequencies were used to create RF (Radio frequency) sideband frequencies which would hit the correct higher harmonic RF frequencies that would kill or devitalize the organisms. Dr. Rife’s engineer, Philip Hoyland, built all of Dr. Rife’s instruments from 1935 to 1938. He built the instruments that used the audio frequencies and never told Dr. Rife or any of their business partners in the Beam Ray Corporation how the instrument worked. Philip Hoyland was trying to protect his interest and the Companies interests from those who might try to steal their technology. This was necessary because they were not able to patent the frequencies or the Rife Ray equipment. This was due to the fact that all this technology was in public domain. Philip Hoyland ended up taking the Beam Ray Corporation to court in a legal dispute, which he lost. Though Dr. Rife and the Beam Ray Corporation won the legal battle against Philip Hoyland they still did not find out how Philip Hoyland designed these audio frequency instruments to work on harmonics. The Beam Rays Company came to its end in 1939 because the legal battle bankrupted the Company. The secret of Philip Hoyland’s audio frequency instrument remained hidden until 2010 when an original instrument was analyzed.
No one knew how the Rife Ray #5 or Beam Ray Clinical instrument audio frequencies worked with the high RF carrier frequency. Due to this lack of knowledge many people have been wrongly using the audio frequencies for the treatment of disease. What even made things worse is in the 1950’s two of Dr. Rife's business partners, Crane and John Marsh, lowered the audio frequencies by a factor of ten times. This decision was made because they did not understand how the instrument really worked.
The changes that were made at this time compromised the instruments effectiveness. Because of these mistakes the wrong frequencies have been used for almost 60 years and people have built instruments that can only output low audio frequencies. This means that almost all the frequency generators that people call "Rife machines" which are sold on the market today are limited to just low audio frequencies and cannot output Dr. Rife's original high RF frequencies.
