Yes Trev - The numbers are substantial abeit scattered population-wise - 2-10% is a lot of people! Wind farms have only the energy from their blades to contribute to LFN. Electricity transmission lines have all the power that is on the gtid.
An addition to my last response to Geoff: This B-PLC/BPL problem is global in nature – It’s been, and is being, installed worldwide. Some countries have rejected it in its entirety. Others are ripping it out and replacing it with a safe more effective alternative (there is only one). At least 5 States in the USA, with 2 more pondering, have vetoed its installation. The ARRL is kicking up, but have signed off on the associated notched frequencies – The electrical utilities et al are ignoring their (legally binding) promises to the ARRL, so sparks will shortly begin flying. The ARRL can shut this thing down in its entirety in the USA. They already did once. The REAL victims are being ignored wholesale. Geoff – Whoever solves this problem will make the headlines worldwide and all that that entails. Personally, I simply want my life back and a little compensation. Someone else can take the accolades. My son gets the paper for his PhD.
