I agree that the method used is not the same as Dr. Clark but what I am saying is that it may well be that the end point is the same: the creation of specific harmonics that have a negative effect on the cancerous cells, virus, bacteria, etc.
Also, I want to say that there can be exceptions to almost anything. The purpose of the square wave is to produce harmonics, The purpose of modulated RF, in this case, is to produce harmonics. The whistling into the CB is producing sidebands ( harmonics ).
While not identical, it definitely gives credence to Rife and also gives credence to Clark in that frequencies do work although they may be generated by different methods.
From my own experience, the zapper absolutely had an effect on my cancer. It was gone very quickly.
