Perry, hams generally don't have any problem with HomePlug devices, they
would like access BPL to emulate HomePlug's notching of the amateur
frequencies. The HomePlug/ARRL test report is at:
http://www.arrl.org/tis/info/HTML/plc/f ... c_2000.pdf
With regard to security, the signals do not get through transformers -- one
would have to bypass the transformer to get the signal beyond it, which is
one of the hassles with access BPL; and line attenuation/mismatches limit
the practical transmission distances as well, it is low power (Part 15
limited for those familiar with FCC rules).
Shane, with regard to surge protectors, depends upon the type. Many
(most?) home surge protectors suppress frequencies in the 1-30 MHz range
for
RFI protection, and since the HomePlug devices use this same frequency
range, the desired signal would be attenuated by such devices, which is
not
esirable (obviously).
