"Dr. Rife's 1936 high RF frequencies"
"Dr. Rife always used high RF (Radio frequencies) on these organisms."
"The FCC actually has imminent domain over all frequencies in the U.S. and only licenses there use."
"They had to apply to the FCC for a new carrier frequency to be used in the rebuilding of the Rife Ray #5 or Beam Ray Clinical instrument"

"Several researchers also have discovered that certain frequencies of radio energy can promote the healing of bones, kill bacteria and viruses, and improve health in a variety of ways (some of these procedures, it should be noted, are still to be unequivocally verified by strict and universal scientific method)."
