For me this discussion is of a minor problem. I have had a wood products company move within 200 yards of my antenna field. Not only have they caused a rather loud audio noise but they have installed a 100 Horsepower Air compressor with a VFD drive. They also have large sawdust moving blowers that run on VFDs and they have mentioned how environmentally conscious they are. These items have raised my heretofore very low noise level by over 20 dB. I manufacture low noise receiving systems and now I no longer have a way to test them here. This also ruins my 160 meter DXing. I have not confronted them yet. I have spoken to the power company investigator and we have a plan to make sure our doorstep is very clean before I confront the company. I moved one of my systems 1200 feet away from any power lines etc. but still have a 18dB increase in the noise floor. So the bottom line for me is that these little devices in this discussion pale in comparison to the very large problems being generated by "Green" companies making VFD drives (Variable Frequency Drives) and not making customers buy suitable filtering and proper installation for them. Yes if you drive by their power line while listening to the a.m. band ANY station will be obliterated. This line goes around the corner and right by my farm. I have a lot of work to do before this is over. Lee K7TJR OR _______________________________________________ RFI mailing list RFI@contesting.com http://lists.contesting.com/mailman/listinfo/rfi |
