>As for the stable waveform, not sure what you are referring to but there are some who use the term that know nothing about what they are talking. Kind of like the claim of some that they can get even harmonics out of a square wave. Not mathematically possible.<
This stabilized wave technology that I read from the Ultimate Zapper meant that the square wave would be somewhat cleaner even on the the load on the copper handles. Although I don't know if that is true or not, similarly having to use a wall adapter with the health zapper worries me. At least the ParaZapper uses only batteries, so I give credit to that.
Why did Hulda Clark choose 30Khz as her main frequency...I assume after she tried 2.5khz?
If she is using 30khz as her main frequency, I assume that frequency does a whole lot for most parts of the body? Then again, the lower the frequency gets, the more harder the wave hits you and you can feel it more. I am confused as to which frequency is better, a higher frequency, or a lower frequency for the overall body.
