I didn't know for sure and I'm a very objective investigator. To sum it up, I found out that communications in the United States are shielded by the F.C.C. who fly over once a year to check for breaks in the shield. Phone company employees, for one example, have to check the shields throughout the year for leaks. This makes it unlikely that communications are open to be recorded.

I also learned that the frequencies at which cell phones, baby monitors, cordless phones etc.broadcast at too high a frequency to account for E.V.P.s. MOST E.V.P.s are very low in frequency and aren't even high enough to be blamed on a human. And the higher frequency Class A E.V.P.s are still not high enough to come from Radio Waves.

In addition to this evidence, I, like many other E.V.P. researchers, have RESPONSIVE E.V.P.s and many of us, have one - two regular spirits we record.
