[Fists] BPL

[Ralph Sutton]

Re the BPL controversy.

At present data transmitted through phone lines or "so called" wireless
connections doesn't seem to impinge on amateur HF transmissions.  I am a
true amateur as far as technical matters are concerned, so I consulted a
friend who had a career in radio.  He explained that the problem with BPL is
that the cables are not screened, so that data transmitted through that
medium will radiate.  To me this did not seem a logical explanation as even
though nowadays with optical fibre transmission and underground cabling
there is a high proportion of unscreened copper wire above ground and for
house connections.

Perhaps one of our more learned FISTS members can tell me if I am wrong and
if so what is the problem with BPL? Or is this another example of the
scaremongers art like cellphone towers supposedly causing awful illnesses.
