The recommendation is therefore that the stimulation should be applied with a 2500Hz carrier medium frequency sinusoidal alternating current, burst at 50 Hz (10ms ON: 10ms OFF) at a maximum tolerable level.
Newly discovered gating frequencies for cancer: run Rife's primary cancer frequencies of 1,604,000 Hz. and 11,780,000 Hz. using a Gating frequency of 1300 Hz. or 1330 Hz. with a Gating Duty Cycle of 27%. Morgellons Frequency as reported by researchers: 2114 Hz. - This may be used as a Gating frequency.
