ARRL: "Utility Encounters Mixed Success in Avoiding Amateur Spectrum with BPL"

The ARRL is opposed to BPL (broadband over power line) technology deployment in the U.S. out of concern for potential interference to amateur and other HF (high frequency) radio operations. In North Carolina, Progress Energy has worked proactively with amateur radio operators near their Wake County BPL trial site to address interference concerns. An ARRL article reports on the project, which uses BPL equipment from Amperion.

I'm surprised the Amperion equipment requires operator intervention to shift frequencies when an interference issue arises; I hope they'll develop gear that does this automatically on the fly as it occurs. This is a capability we'd want to see before recommending it to our utility customers.
