Tech Quick Tip: EMF Probe Part 2
July 23, 2013 in communityblog, ghost, paranormal, Weird Science
If you thought the EMF probe we talked about in the previous Tech Quick Tip was a one trick pony, you’re in for a surprise. The pickup coil used in the last article was designed to pick up the varying magnetic fields of a telephone speaker and record them. So it stands to reason that if you want to listen to EMF, it should be easy to hook it up to an audio recorder. And it is, provided the recorder has a line-in/external microphone input jack.
Why would you want to?
There are a number of different experiments that you can try out. The first is simply using two of the same style audio recorders. One for recording standard audio, the other for recording EMF from the probe. Set these recorders on the same settings, start them at the same time, and keep them just a few inches apart. Start an EVP session and cross your fingers for some interesting findings.
Another way to use this same setup is as a data logger, something that keeps track of EMF. You may have seen EMF meters go a bit wonky while performing a paranormal investigation. By using a meter in conjunction with an EMF recorder, you may be able to see a pattern that wasn’t obvious in the heat of the moment.

Using headphones on a voice recorder using an external microphone makes a good REAL TIME Amplifier of sounds. For more sensitivity use a large speaker as a microphone . I used an outdoor P.A. speaker ( again from Radio Shack ) and found if left outside you can hear the neighbors talking from two blocks away ! When left in a quiet room it picks up sounds at the lower end of our hearing frequency’s so that Real time EVP communication is possible.
