Zeroing in

(1)

I finally got around to reading this, which clarified the the situation considerably. The information I was searching for was near the end of the report. I quote:

'The sensation reported by the 367 men and women for frequencies below 100 kHz was tingling or pricking, localized in the area adjacent to the region of contact on the finger or hand; for frequencies above 100 kHz and finger contact with the plate electrode, the sensation was warmth or heat in the area below and around the plate electrode; with grasping contact, warmth or heat was felt in the hand and wrist. To determine more accurately the frequency for transition from tingling to warmth, data were obtained for some subjects at 50 and 70 kHz. At 50 kHz, the sensation reported was always tingling, but at 70 kHz, some subjects reported tingling and others warmth. Moreover, when the current was raised slightly for those who reported tingling, the sensation changed to warmth. In addition, for frequencies above 100 kHz at which warmth was felt, when the current was adjusted to be equal to the perception threshold, pain was reported typically within 10-20 seconds, an effect that was not observed for frequencies below 100 kHz.'

So my 3mhz-5ghz device could not detect the offending RF, which is much lower in frequency. By the way, the device name is, 'Zap Checker' model ZC 185. It is sold by Alan Broadband Co for about $170. I recommend it unless you are being roasted at a much lower frequency. I do not at present have a device to detect such low frequencies. I'll work on it next week. See the US frequency allocation chart. It shows the frequencies 50-300 kHz to be mostly in the 'maritime mobile' part of the spectrum. Interesting.
