A development of EVP from about
1980 is what is termed Instrumental Trans-communication (ITC). In this
investigators use a wide range of equipment - telephones, radios, televisions,
answering machines, faxes and computers - to establish contact with the dead.
These results are often highly evidential with the ability to maintain
conversations with, and even to obtain pictures (on TV) of, relatives and
others who have died. Three books describing much of this work are:
Rogo, D. Scott & Bayless, Raymond (1979). Phone Calls from the Dead. New English Library, London.
Fuller, John G. (1985). The Ghost of 29 Megacycles. Souvenir Press, London. ISBN 0-285-62691-4.
(Also published 1987 by Grafton Books, London).
Kubis, Pat & Macy, Mark (1995). Conversations Beyond the Light. Communications with departed friends and colleagues by electronic means. Griffin Publishing/Continuing Life Research, Boulder, Colorado. ISBN 1-882180-47-X.
This relatively recent book is of
particular value in that it contains, amongst much other material, a chapter on
"Getting Started" with ITC and a section of evidential material -
pictures of ‘dead’ people transmitted from the other side of death via video
and computer-generated images.
Useful reviews of EVP can be found in
Brooksmith and Zammit (pp. 5 and 9 respectively, above) and of ITC in Zammit.
Although, as with much mediumistic communication, some of the results from
these techniques are both trivial and can possibly be being derived from the
subconscious minds of the operators/sitters, there has nevertheless been a
great deal of highly evidential material produced by these techniques which
supports survival.
