Some of the noise must be coming from quite a distance.
...indeed it seems that way. Suburbs and large cities are now, sadly,
enclosed in a huge shroud of RF crud thanks mainly to switching power
supplies, plasma TV's, microprocessors in almost everything along with miles
and miles of highly effective powerline 'antenna' systems to radiate this
garbage. Get a few miles away from the cities / suburbs as well as the
powerlines and it is an entirely different world.
