By now I hope everyone knows that Rifes secrets died with him. He was holding out for a buyer. We only know 10 of the original Rife frequencies and anyhow how they were modified and directed to the body was just as important as the frequencies themselves and that method is not copied in the modern Rife machines which in all truth are Crane machines. (Crane was his assistant that made his own simplified version.) I used to sell "Rife" machines but stopped because of lack of positive feedback from customers. Beck treatments are much more effective.
