: Rife's original frequencies were typically in the high RF range, often between 100 kHz and 4 MHz . Philip Hoyland and the Sideband Method

The relationship between Royal Rife and Philip Hoyland is central to the history of the "Rife Machine" and the specific frequencies used in alternative medicine. While Rife identified the original frequencies, Hoyland developed the delivery systems that introduced the concept of sidebands and harmonics. The Foundation: Royal Rife’s MOR

It is important to note that these claims lack modern scientific validation:

: Hoyland developed a machine that used a fixed high-frequency carrier mixed with a lower audio frequency .

: During a 1939 lawsuit, Hoyland admitted he had hidden the true nature of his frequency-mixing method from Rife to protect the company's trade secrets. A History Of Rife's Instruments And Frequencies.pub - YUMPU

: Organizations like Cancer Research UK state there is no reliable evidence that Rife machines or these specific frequencies can treat cancer or other diseases in humans.

: Because the machine's primary settings were low-frequency (audio), many users began to mistakenly believe these audio frequencies were the actual "healing" frequencies, rather than the high-frequency RF sidebands they created. Key Differences in Frequency Philosophy

: Rife’s original machines were difficult to tune and expensive to build for commercial use.
