    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.
