Ghost Box or Frank's Box
This is one of the more experimental pieces of equipment used in the paranormal world. The jury is still out on wither or not it actually works. I personally own a Shack Hack, which is a cheaper home made version of the Frank's Box, but it works along the same lines. I haven't had a whole lot of luck getting any intelligent responses from it, however I also haven't had a sufficiant amount of time using it either. Since it is highly experimental, I tend to not use it on alot of investigations. Once I get a chance to learn more about it and work with it more, then I will be able to form a better opinion on it.
A Brief Explanation:
The Frank’s Box is designed specifically to capture EVP. It was invented by amateur radio enthusiast Frank Sumption, who was inspired by a “How To” hobby article about recording EVP that appeared in the now defunct Popular Electronics magazine. Upon receiving design instructions from the spirit world and the article, Sumption built a radio receiver that reputedly facilitates real-time communication between the living
and the dead, not to mention extraterrestrials, angels, spirits, and assorted
entities from other dimensions. The Frank’s Box device is one of several incarnations. It is also known as the Ghost Box, Joe’s Box, the Spiricom, the Mini-Box, the Telephone to the Dead, or the Shack Hack, according to the design, the manufacturer, and the faction.
How Frank’s Box Works
The Frank’s Box is a homemade radio frequency receiver. However, this radio
isn’t designed to find your favorite radio station; it’s built to be broken.
The scan-lock mechanism is disabled on this “radio.” Therefore, the machine
continuously scans radio frequencies at a predetermined rate. This is like
twisting the knob on a radio backwards and forwards quickly, producing random
noise. This “sweep method” creates an untunable radio of erratic white noise.
The rushing sound of unused frequencies is punctuated by mostly unintelligible
fragments of speech or music when the scanner momentarily picks up a station.
It is Sumption’s belief that “spirits” and other entities from beyond manifest
in an “echo chamber” built into the unit and harness the random signals to
create messages intended for the mortal listener.
Sumption describes how he believes his device works as a medium.
[This is] "Simply another method of supplying “raw” audio that spirits and
other entities can use to form voices. Raw audio is a sound source that
contains bits of human speech, music and noise, and a convineint source of raw
audio is a radio with it’s tuning swept across the entire band, AM, FM, or
shortwave. The sweep can be random, linear, or even done by
hand." Sumption added: “I think it’s no more unbelievable than the so called thought experiments of quatum physics. If I had a Ph.d, maybe what I say would be accepted without question as well.”
EVP-ITC member Tom explains some theories on how this may work. We Don’t really KNOW how it works, but only that it DOES seem to work. In EVP we have at least two major theories. In the EM (Electromagnetic)theory, we assume that the spirits are communicating with voice modulated EM waves--either via a kind of “radio technology” or the “fact” that sound waves from the other side are Electromagnetic relative to our own universe. This explains why we often need a device like a electric sound recorder to hear the waves.
The other major theory, and the theory he subscribes to, is that the voices are made from existing background sounds. This is sort of like using an electronic larynix or holding an electric razor to one’s lips and “mouthing” words. The vocal appratus changes shape and resonance characteristics, making a sufficiently randomized sound(like a buzzing razor) sound like words. Spirits may do something similar, near an EVP recording microphone, either “semi-manefesting” a vocal apparatus or by utilizing some of their own sound altering technology.
The third theory involves the listener putting the background noise together somewhat selectively--in one’s own mind, so to speak. The noise itself which forms which is called a “random field”--- One of the “psychic levers” which effectively enhances one’s psychic abilities to useful levels.
