Spectrum pollution

There is little doubt that the noise floor is increasing at LF, MF, HF and VHF. This is especially acute in towns, but even in my village you can see it is getting progressively worse. With the likelihood that electric cars will become more commonplace, things could get even worse with wireless charging.

Southgate News has a link to Don Beattie's paper all about this.
