Tell me if I have understood the concept correctly.

You take a radio receiver, let it scan or sweep the band without stopping or locking onto stations so you get snippets of music, voices from announcers, static etc, mix the hotchpotch with white noise, record it onto a tape recorder which on playback turns into spirit voices?

You see to a skeptic this sounds like three fold mis-use of equipment. One is to snippet scan a radio broadcast for incomplete, partial or random words/sounds. Two is to blur it with white noise which raises the chances of hearing the words as something else. Three increases the possibility of mishearing, or possibly hearing what we want to hear by recording degradation.

But then with most ghost hunting equipment this is the desired result. The uncertainty factor.

I also have a problem with selective spirit manipulation of computers. Here's an idea, place a computer down on the desk, open up word pad or some similar program, and tell them to start typing! If they can manipulate certain aspects of the PC surely they can make words appear on the screen?

 Not quite, I don't mix  the radio noise with anything. the sound from sweeping the raddio across it's tuning range is what the entities use to form voices–at least that's how I think it works.

 I do have a site up with some examples and schematics. What's not shown in the schematics is the radio tuner, as I use different ones, my favorite, othe ones wiht he best audio are the Radio Shack Arm Band radio, and the Radio Shack #12-469, I use both with the control, or processor board removced so I can sweep the tuning wiht an external voltage. http://purplealiengirl.tripod.com

 I get too much in between station noise in home made radios, which almost wipes out the broadcast portions.so I rely on store bought radios, and sometims tuner modules from digital car stereos, but these tend to too noisy as well.

 There is a researcher here in Colorado, Mark Macy of World  ITC (worlditc.org) that claims to have gotten messages from computers. printers and telephones.  He may have been only associated wiht a group that claims these contacts, I'm not sure.

 Presonally, being an old ham operator, I prefer radio, that's what keeps me intrigued with this stuff.

 Granted, even after almost ten years of this mind numbing stuff, I still mis hear, or imagine some stuff, it's unavoidable. There's is the problem that valid ghost voices kind of pop into the audio form the swept radio, they are phrases that have meaning, and you would not expect to find in the sweep if it was normal radio reception. They tend be spoken even as the sweep contiues.  I put an example on my site, on the "recent voices" page, from last weekend. Unedited, and unseperated from the radio sweep. Normally, when I share the voices on-line, I seperate them out, but usually do not filterier, or use noise reduction.
