1950's)Ĭ2) multiple sideband device as above, but with floating earth etc as described by Dan Jensen (Beam Rays 1939). ![]() effectively this modulates with a harmonic set of low frequencies (AZ-58 c. 1934, pentode valves and on-board power suppliesĬ1) AM to obtain multiple RF sidebands. 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.ī) superimposing two RF frequencies F1 and F2 to generate a low frequency component F3 (dual RF heterodyning). Ī) superimposing a low frequency with an RF frequency (lo-hi superimposition). I wrote in other posts comparing some electronic schemes for gas tubes that may have been tried at different times. 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 am trying to convince people to re-invent these.ĭifferent people insist on different interpretations of the history. I dont think anybody today really knows how that system worked, and today nobody makes or sells anything like that. Rife didn't use carrier modulation but the mixing of 2 frequencies in his second machine.I also beleive this is true.
