I received an email from a Rife researcher in the UK explaining how the group there had figured out the original Rife BX frequency used in the 1934 clinic.
They came up with 12.832 MHz. In testing here with an F165 we came up with 12.833 MHz. We are now using the sweep 12832500-12833500. This tests much better than 11,780,000 which has worked so well.
A lower octave would be 3133.0565 Hz with a sweep of +/- 0.1 Hz in 0.001 Hz steps. One researcher who tried this frequency using an EM8 plasma device found he had to limit the run time to a fraction of what he had been doing with the usual frequencies.
