The following are signal details suggested to those interested in experimenting in voice-to-skull radio transmission or with bioeffects of microwaves in general. The owner of this web page has not yet succeeded in any of these areas, but the information here has been suggested by both rigorous and non- rigorous articles on the subject.
FOLLOWING ARE BRIEF EXCERPTS FROM OR SUMMATIONS
FROM ARTICLES SPECIFIC TO VOICE-TO-SKULL TECHNOLOGY

Science, vol. 181, 27 July 73, Allan H. Frey and
Rodman Messenger, Jr.:
p. 356: Perception occurred when the subject
was illuminated with energy from approximately
that portion of the EM spectrum defined as the
UHF band, that is, from 0.3 to 3 GHz.
p. 357: An approximate threshhold for perception,
when the subject was in a noisy environment,
occured at a peak power density of 267 milliwatts
per square centimeter...
p. 358: There are also RF modulation parameters
that cause subjects to report hearing "sounds"
with definite pitch and timbre characteristics.

** These excerpts deals with microwave-induced
muscle-jerks, rather than voice-to-skull:
p. 636: With the antenna mounted vertically
above the cage, it was observed, a few seconds
after the onset of radiation [16 GHz, 8,000
pulses per second, 10 to 30 milliwatts per cm2]
that sustained extensor activity of a wind and
leg occurred - a reaction possibly due to the
penatration of induced electrical activity
to the spinal cord. Shielding first the head
of the chicken, and then the body leaving the
head exposed, produced no significant change
in the manifested extensor activity.

Journal Acoustical Society of America, June 1982,
Chung-Kwang Chou, Arthur W. Guy, and Robert Galambos:
[This article is a detailed "proof" that the
"microwave hearing" phenomenon is thermal in
nature. The calculated temperature rise due
to the pulses studied is a surprisingly small
1/100,000th to 1/1,000,000th of a degree
centigrade. - E. W.]
p. 1321: ...the absorption [of microwave
energy] can be appreciable at the resonant
frequency near 70-80 MHz (where the long
dimension of the [human] body is approx-
imately 0.4 wavelengths. For a human head,
the resonant frequency is near 600 MHz.
p. 1324: [Describes audio frequencies applied
as pulse repetition rates - roughly speaking,
rep rates from 1,000 to 12,000 per second
were tested and produced various sounds.
The suggested pulse durations were in the
range of 5 microseconds to 150 microseconds
- E.W.]
pp 1324-1325: In summary, there is uniform
agreement that human beings with normal high-
frequency hearing can perceive an auditory
sensation when exposed to microwave pulses
of sufficient energy content. The [UN-
modulated] RF sound may be perceived as
clicks, buzzes, or hisses depending on the
[pulse repetition rate and duration]. This
received sound, at least for pulses less
than or equal to 50 microseconds seems to
originate at the central, posterior aspect
[i.e. back] of the head.
Bioelectromagnetics conference, 1992, 13:323-328:
[This article deals with modification of the
ability for a sudden sound to startle rats,
and does not deal with microwave hearing.
