There is another trhaet. This one not as visible or immediate as CC&R's. That trhaet would be the one creeping in from the edges of our radio dials by increasing our radios noise floor. The unregulated import and manufacture of switching devices, each carrying with it more spectrum pollution than the last batch is ruining our ability to communicate just as surely as taking antennas away. This noise has easy ingress into our receivers through CM propagation along house wiring. Low voltage and high di/dt currents found in these devices are becoming as pervasive as shoes, socks and toothbrushes were fifty years ago; and no one is watching the fort! There are laws but no enforcement.
