With ever burgeoning sources of manmade noise (various energy efficient
lights, switching supplies, computer related hardware, etc.) it would seem
the only real way to escape the noise problem is to abandon the the
urban/suburban areas and move to the country. Even then casinos, wind
energy farms, and other commercial enterprises can move in to create
unsolvable, multiple noise sources from multiple directions killing the
prospects for a low noise environment, especially on TB. My noise floor on
TB out here in the Iowa countryside has gone from somewhere in the -130 dbm
range to about -107dbm (or more)@250 Hz bandwidth during daytime hours. .
.and it's not power line noise. New houses have popped up 1/2 - 3/4 mile
away and with every new one the noise floor continues to creep upward. My
biggest noise source used to be electric fences in various directions, which
the NB took care of nicely. Now the problem has changed and can't really be
solved. . .except to perhaps move out further. 73. . .Dave, W0FLS

We can all thank our lucky stars that plasma TV has got to the point where
vanishing popularity has got its numbers down to where it no longer has
economy of scale. Economics are killing it.
What you can do at your neighbor's party is to pour some Pepsi inside his
TV and hasten it's demise. Sledge hammers would work too, but it's hard to
be covert using a sledge hammer. The replacement will be LED-based, which
happily now has both quality and economics of scale tilting positive.
The new radio killer will be solar cells that have individual controllers
so a shadow on one part of a panel doesn't kill the whole panel. New
battle, new economics, new solutions.
