George - The effect of low frequencies on the human body is well understood by no less an institution as the CIA! Indeed there are stories of LF "warfare" in Moscow with the aggressor being the Russians and the victims the US Embassy! The effects you describe are very similar!

Chris, On the topic of RF exposure, I will throw in my two pennies. Years ago, I was interested in the topic of frequency jamming of radio stations. I thought it would be interesting to build a frequency jamming device that would cause home radios to stop working. I built a random noise generator that produced noise in the frequency range of 100Hz to about 1MHz. I used the noise generator to drive a loop antenna (2 ft diameter) with a max current of 2.5A. The device worked very well in stopping AM radios from receiving the broadcast when I bring the loop close to any AM radio receiver. But as I was waving the loop in the air with my arm, I felt sever dizziness and a slight headache whenever the loop came close to my head. And I felt a difficulty in breathing when I placed the loop next to my chest. These are completely unmistakable feelings in the way that as I moved the antenna 3 feet away from my body, immediately, the feeling was gone. The effects were very repeatable and the symptoms were immediate (within a few seconds). I knew! this was not a thermal effect because the frequencies were way too low. I just knew that the fields were causing my organs to "malfunction." After that, I stopped using the device. I don't think you can attribute this to any coincidence.

Oscar - I spend a lot of time debugging systems and separating coincidence >from cause so I appreciate your skeptic stance. I would agree that it was not a controlled experiment but it was my experience that I wanted to share. My exposure was over a good part of a month and my flu like symptoms happened at the exposure time and stopped ~ 4hrs+ later after leaving the area. I would estimate ~ 15 exposures events over that month and then many months before and after without any problems. As a result of my experience I am being cautious, limiting unnecessary exposure and since I work with power being observant of other situations. Chris Wells From: "Oscar Overton" <oover...@lexmark.com> Chris, Until you can do this repeatedly and the results are the same, you have only demonstrated a coincidence.
