Pulsed Microwave Technology
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, (Willow Grove, 1965) 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 that this
power level is only applied or needed 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. This is the concept of ”spike” waves used
in radar and other military forms of communication.
Frequencies that act as voice-to-skull carriers are not single frequencies, as, for example TV or
cell phone channels. 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 usually have the carrier frequency ”hop” around within a specified band.
Unless a receiver ”knows” this hop schedule in advance, like other forms of encryption 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.
The actual method of the first successful unclassified voice to skull experiment was in 1974, by
Dr. Joseph C. Sharp and Mark Grove, then at the Walter Reed Army Institute of Research. A
Frey-type audible pulse was transmitted every time the voice waveform passed down through the
zero axes, a technique easily duplicated by ham radio operators who build their own equipment.
The sensation is reported as a buzzing, clicking, or hissing which seems to originate within or
just behind the head. The phenomenon occurs with carrier densities as low as microwatts per
square centimeter with carrier frequencies from 0.3-3.0 GHz. By proper choice of pulse
characteristics, intelligent speech may be created.
Dr. James Lin of Wayne State University has written a book entitled: Microwave Auditory
Effects and Applications. It explores the possible mechanisms for the phenomenon, and
discusses possibilities for the deaf, as persons with certain types of hearing loss can still hear
pulsed microwaves (as tones or clicks and buzzes, if words aren’t modulated on). Lin mentions
the Sharp and Grove experiment and comments: ”The capability of communicating directly with
humans by pulsed microwaves is obviously not limited to the field of therapeutic medicine.”
