Did I say there was anything special about it? It is a LF MOPA with screen modulation of the PA. What is special is the claim that you can detect the output, an AM signal, inside your body. You could make the signal in other ways, of course. >Unfortunately, the only conclusion I've arrived at is QUACKERY... I don't know if it works or not, but I'm not seeing anything there that would be quackery. Quackery is a pretty serious charge. A quack is someone who pretends to be a medical doctor, and quackery is the practice of such. I'll back away from the discussion as it getting pretty far off-topic. I simply wanted to mention this "thing" that is related to people and radio waves. I'm not making any claims for it other than I found it interesting.

Circuit 7 is a phase-shift oscillator, driving circuit 10, an RF amplifier that is Screen-Grid modulated by circuit 19. The thing that I find odd is that the RF Amplifier is not 'tuned'... The plate circuit consisting solely of item 16, a step-down transformer of some sort, that drives a step-up transformer (also untuned) with a load resistor connected across it's secondary winding, then to a pair of non-descript 'electrodes'. Over all, it's quite crude... I'd be quite concerned about any degree of heating that this RF generator might produce, modulated or unmodulated... I've studied the information presented at neurophone.com... Unfortunately, the only conclusion I've arrived at is QUACKERY... Why use digital modulation when mammals are analog in nature...? It's been stated that one could patent a ham sandwich if it was scientifically described. Allowing anyone to apply an electrode of this type to a person's head or spinal column is ludicrous... Where are the lab trials on lower order animals..? and if they were conducted, what were the scientific results..? I've spent over twelve years working with Neuro-Psychologists and Audiologists studying many areas of the human brain and the myriad ways that the brain processes information, visual, auditory, tactile, and by direct stimulation... We had never been presented with a device or methodology of this nature... If there is any real substance to this 'neurophone', I'd certainly like to see some real, honest-to-goodness scientific evidence... ...Larry, W1GOR (Queens College, Department of Psychology, City University of New York (CUNY), 1966 through 1979...)
