You use a carrier with a good zapper’s frequency, like 10kHz.
Chopping this 10kHz carrier 7.83 times per second (isochronic modulation) will give you two different effects :
10kHz for a good zapping session, giving you all the benefits of this popular Rife frequency.
7.83Hz, perceived by your brain, and entraining it to this beneficial and
JAB
If you can get that carrier above 1 MHZ that would be even better. Above 1 MHZ the body offers little resistance. The frequencies will pass through cells and bone.
