I have an unanswered question about BPL. Where I live has a very old

power

line system, full of splices and corrosion. How will splices affect the

1) the

internet signal and 2) RFI?

The internet signal will be crappy and subject to interruption by static
from all kinds of sources. RFI generation will be severe. I do not know
whether the splices and corrosion will make it worse but it certainly won't
help matters.

If open wire (telephone line) is a precident- ANY HI RESISTANCE, or ground, or
arcing in the instance of power will cause an unbalance of the circuit. This causes
a very high noise level on that circuit pair,
and would also cause it to RADIATE interference! And,
consider, that power companies have substancial arcing (caused by dirt, and loose
hardware), and ESCAPE (the induction from an A.C. line to other objects, if the
voltage is high enough and the magnetic field is strong enough), like fence lines
and telephone co. messenger (the steel cable that supports their telco cables),
paralleling it, and arcing to ground - there are several undesired effects even
WITHOUT BPL to cause QRN ! And btw, it is NOT necessary for a very good ground
to cause problems- just tree limbs are enough to cause a problem in this area.
ONLY GOOD part of the situation is the more current that flows thru the wire
(and hence the sleeves), the internal arcing in those bad sleeves tends to "SEAL"
or heal themselves for a duration- but if the current lowers to a substantial
amount, the problem will be BAAAAAACCCK !!! As info, Jim NN7K
