Why not?

Tune your radio to 60 Hz.

After BPL 2 mHz to 80 mHz (and their harmonics) will have trash on the
whole spectrum.


C'mon Gene, try to make some sense here will you?...why should
one tune to 60 Hz? (the power line freq btw). Pls do explain what
the hell you're talking about.

I presume he is trying to make the, valid, point that all those power
lines radiate a very nice signal at 60Hz, and by implication that they
will do the same if BPL is permitted to transmit digital data between 2
and 80MHz over the same lines.

It's late, so I'm not going to try and look it up now, but IIRC BPL has
been banned in some administrations for precisely that reason - ISTR
that Japan is one such administration.

BTW John - Long (very long) wires make excellent antennas provided that
they are at least several wavelenghts long.


Don't they tend to be directional off the pointy end?
