=========================================================================== V. PULSED MICROWAVE Pulsed microwave voice-to-skull (or other-sound-to-skull) transmission was discovered during World War II by radar technicians who found they could hear the buzz of the train of pulses being transmitted by radar equipment they were working on. This phenomenon has been studied extensively by Dr. Allan Frey, whose work has been published in a number of reference books. What Dr. Frey found was that single pulses of microwave could be heard by some people as "pops" or "clicks", while a train of uniform pulses could be heard as a buzz, without benefit of any type of receiver. Dr. Frey also found that a wide range of frequencies, as low as 125 MHz (well below microwave) worked for some combination of pulse power and pulse width. Detailed unclassified studies mapped out those frequencies and pulse characteristics which are optimum for generation of "microwave hearing". Very significantly, when discussing electronic mind control, 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 pulse's 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. -12-
