Very significantly, when discussing electronic harassment, is the fact that the PEAK PULSE POWER required is modest - something like 0.3 watts per square centimeter of skull surface, and this power level is only applied for a very small percentage of each pulses cycle time. 0.3 watts/sq cm is about what you get under a 250 watt heat lamp at a distance of one meter. It is not a lot of power. When you take into account that the pulse train is OFF (no signal) for most of each cycle, the average power is so low as to be nearly undetectable. Frequencies that act as voice-to-skull carriers are not single freq- uencies, as, for example TV or cell phone channels are. Each sensitive frequency is actually a range or band of frequencies. A technology used to reduce both interference and detection is called spread spectrum. Spread spectrum signals have the carrier frequency hop around within a specified band. Unless a receiver knows the hop schedule in advance, there is virtually no chance of receiving or detecting a coherent readable signal. Spectrum analyzers, used for detection, are receivers with a screen. A spread spectrum signal received on a spectrum analyzer appears as just more static or noise. My organization was delighted to find the actual method of the first successful UNclassified voice to skull experiment in 1974, by Dr. Joseph C. Sharp, then at the Walter Reed Army Institute of Research. Dr. Sharps basic method is shown in Appendix PM6, below. A Frey- type audible pulse was transmitted every time the voice waveform passed down through the zero axis, a technique easily duplicated by ham radio operators who build their own equipment.
