I also beleive this is true. I dont think anybody today really knows how that system worked, and today nobody makes or sells anything like that. I am trying to convince people to re-invent these.

Different people insist on different interpretations of the history. Some people insist that the monofrequency approach would be Rife's choice, but there are comments in the archives that clearly contradict that interpretation .

I wrote in other posts comparing some electronic schemes for gas tubes that may have been tried at different times ...

A) superimposing a low frequency with an RF frequency (lo-hi superimposition) .... pre-Hoyland and based on triodes, five output valves in parallel based on Navy MOPA circuit, but possibly with modulation stage not used, battery bank power supplies.

B) superimposing two RF frequencies F1 and F2 to generate a low frequency component F3 (dual RF heterodyning) .... 1934, pentode valves and on-board power supplies

C1) AM to obtain multiple RF sidebands ... effectively this modulates with a harmonic set of low frequencies (AZ-58 c. 1950's)

C2) multiple sideband device as above, but with floating earth etc as described by Dan Jensen (Beam Rays 1939). This design had significant frequency drift in the carrier, but personally I do not beleive that is a flaw because the low frequency component was stable despite that drift.

D) Rife-Bare AM ... modulates with a single square wave (unlikely to have been used by Rife).

Comments:

A) This is only my opinion / guess and other people may strongly disagree .... I suspect this worked well on microscope slide samples to demonstrate dielectrophoretic force (DEP) adhesion effects (clumping or agglutination) better than monofrequency (or at least at lower power thresholds) but Hoyland proved it had poor penetration into deep tissue. I outline a simple two-frequency concept, but in a real gas plasma tube device, the output may also include mixing of harmonics. What happens might also depend on whether the signal superimposition occurs in a pre-amp stage or directly in the plasma tube. I beleive the evidence for 5 parallel final valves suggests a single amp that amplifies one (superimposed) signal. Another alternative design that might pre-date this Rife MOPA might use relatively primitive triodes (hooked up as inverters) in series to progressively amplify. This could incorporate AM, but I am voting that Rife was deliberately interested in superimposition.

B) Hoyland's first solution to improve the penetration problem (most other people think this is a dumb complicated idea and that Rife never tried this. But I think it is awesome and I would love to work with a design like that. Nobody has ever messaged me to say they like it, or that they agree it was ever tried by Rife)

C2 An elegant low-cost design that might indirectly deliver a harmonic set of low frequency components via the interference of multiple RF sidebands . BUT does it do a better job that the more expensive design B ???

C1 AZ-58 copied the Hoyland 1939 design but abandoned the floating earth principle in favor of a more conventional circuit . (This also improved the carrier drift). Some people sell modern versions of this style of multiple RF sideband device, but they insist that the bioactive "MOR" is actually one of the RF sidebands. They also insist that Rife's MORs were all within the RF band, meaning that lower frequencies are useless or irrelevant, and the mod frequency is irrelevant, and that MOR is highly dependent on the actual carrier value. They argued that when the AZ-58 altered the original carrier frequency, the designers had no understanding of how the correct amended mod frequency should be calculated, because they were ignorant of the principle of multiple sidebands . With all due respect, my counter-argument is that not enough consideration was given to sideband interaction by these researchers.

Most of these modern multiple sideband devices feature an option for modulation sweep to allow all the frequencies within that part of the RF spectrum to be emitted. I made an unpopular interpretation that the historical charts they refer to list RF sidebands that were convenient to detect and record (more accurate than reading the mod frequency). But on the other hand, given the serious carrier drift, it would be important for calibrating sideband to mod frequency to maintain the equipment with no change of the placement of reactive objects near the tube during the work, and maybe even similar humidity conditions). I beleive the low frequency modulation values are bioactive and the actual RF sideband values are irrelevant, similar to the Rife-Bare paradigm. My personal opinion is that to attempt to delivery DEP force as a therapy, the dwell-times within the effective window should be at least a few seconds. If the modulation is in a sweep mode, I would run the sweep change slowly over a limited window in any given session, not rapidly over a wide window as proposed by Bedini.

D) Rife once used the term "amplitude modulation" and Crane taught that AM was Rife's technology. However this quote may have been referring to the 1939 design. Moreover, signal superimposition schemes even now are described by some people as AM, because you can see a regular envelope in the trace signal. There are theoretical reasons to assume the Rife-Bare devices can deliver a low-frequency MOR (as the mod frequency) because in the simplest analysis there are two RF sidebands that interfere within the target. Some people beleive Rife used a scheme similar to Bare, but using overmodulation instead of square, but bottom line is they may have been misled by Crane.

.................................................. .......

It may be that assuming Rife saw clumping effects (possibly this required custom dilutions in glycerol or sugar solutions to get into a useable DEP window, and most modern Rife researchers may have not been aware of that when attempting to treat bacteria), he looked for a technology that gave the most robust effect, e.g. a device that gave the effect even at modest power settings) ... at some point Rife abandoned monofrequency designs and moved on to two-frequencies simultaneously. Since he had a collaboration with Lee deForest, you would think they would have had a crack at AM, perhaps also by using a large version of deForest's gas triode either as output or as a pre-amp. But from the perspective of delivering an optimal DEP signal, you might consider superimposition instead of AM. Assuming the earlier monofrequency research indicated DEP windows below the RF band, it would seem logical that superimposing RF onto the earlier known LF frequencies would be worth a look. (Hi-lo superimposition) ..... I made a guess that the hi-lo scheme would fail in deep tissue and another guess that Hoyland would also predict that, and a further guess that he might offer a novel dual RF heterodyning scheme as a solution. We do NOT see that well described in the archives, but on the other hand there are obvious gaps in the archives. The one clue that supports my interpretation is a schematic by Crane that modifies an AZ-58 sketch by pencilling in a second RF oscillator stage, shown as connected to the second gas tube electrode.

People might assume the 1939 innovation makes a dual RF design redundant, so why should I prefer dual RF to multiple sidebands ?. One reason is that I know obtaining a fundamental F3 is very different to obtaining a harmonic set. I would say that if I wanted to use extend the research of Kirson et al on cancer cells to improve the existing 200 kHz capacitative plate applicator designs to allow deep non-invasive treatments using RF, I would have various choices to evaluate. My opinion is excluding dual RF would be silly. Moreover there may be some advantages to opposed-wave configurations. Based on Rife's comments criticising harmonic content in the 1939 design, it may be that dual RF might have been Rife's preferred alternative, and the modern obsession with AM is misinterpreted.
