Jim,

Having worked in EMC labs (electromagnetic compatibility), I've heard the
signals generated by some equipment. What you fail to understand is that
these signals are being modulated at very high rates of speed. Inside of
your computer exist a number of oscillators. You assume that only those
frequencies and their harmonics would be broadcast. Do yourself a favor and
put an HF radio or HF scanner next to your computer while it is on. Turn
off the monitor so you won't blame the monitor. Guess what? A ton of
garbage. BPL will be worse since it will be carrying more than one signal
over the power lines. These will likely carry information at a 1.5 megabaud
rate. Check out the ARRL website and view (and listen to) the 26 MB video
they have available showing the radio, S-meter, and the car driving around.
It is a veritable cacophony of noise all over HF.

The fact is that folks such as yourself who are not particularly technically
inclined make statements that other non technically inclined individuals
will believe without actually studying the matter. I can assure you that
your position is totally in error.
