I forgot what band it was, but it was one of the lower ones, "80 or 40", and I was working CW from my mobile. "parked" It took a QSO or two before I realized the RF was effecting me. I believe you. I have felt the effects of using a cell phone for an extended time. A warmth sensation. And not the batteries. There is no question that at some level, tissue heating is noticeable, and I can attest that RF burns tissue at higher levels. When working in the near field of antenna farms this helps you to determine where you should linger and where you shouldn't. Some people linger in the sun too long. Some people are more sensitive to tissue heating than others. Still, after working in the near field of 900 paging antennas with ERPs of 1 to 10 kw, along with numerous other antennas it is hard for me to imagine that a 300 mw cell phone could even be sensed, let alone cause damage. I have seen people who actually complain of RF symptoms with the power off, even in anguish as if in pain or being tortured, conviced that they were being exposed, while thinking nothing of it when they actually were. It would seem to me that a great many people are highly suggestable as evidenced by the changes in our society to conform to media demoralization. There is even commercials for HULU that makes great light of this. Yuri Bezmenov, who defected from the KGB in the 70s warned us about their constant and unrelenting demoralizion techniques to render whole societies unable to come to rational decisions even when confronted with the obvious. He joked that they could tell you the sky was Black so often, that even when they showed you it was really Blue, you wouldn't believe it. Someone mentioned hearing loss. This is an issue I have noticed, but not from RF but from high frequency noise. Many people didn't like CDs because they didn't sound right, and Solid State amplifiers when transitioning from Tube types. Now with some DSP implementations. I noticed this right away with a certain radio that didn't sound bad but was completely irritating and fatiguing to listen to for more than a few minutes until I started using an external speaker with a tailored response. Subsequent to that episode I experienced an overnight hearing loss in one ear of all frequencies over about 1500 Hz in that ear along with a peak at that frequency that is quite tender. It is a known fact that CW ops who use headphones are more prone to hearing loss, so I would really like to see more research and solutions there. |
