Do you have any logical rebuttal to the bit about the BPL leaking out and
ruining the HF spectrum (especially for SWLs, even more than Hams)?
-ANSWER THIS.

My pleasure.

The FCC has, in it's changes announced yesterday, recognized that an
occassional --bona fide-- RFI issue will arise. It has assumed that such cases
will, in some circumstances, occur,and made it the onus of the BPL providers to
provide for appropriate action and mitigation.

There is no evidence, nor reason to believe, that the low level of RF produced
in BPL will propagate to bona fide interference levels, in the very or mid
far-field.

That means that few active fixed-location radio amateurs will be affected in
an adverse way: for example, most HF hams are inactive; and a vast majority of
hams are VHF only these days. A simple sensitivity analysis suggests potential
cases will be a few hundred in the worst, case, a few dozen in the best case.

You may hear BPL; the issue is whether it constitutes true interference. In a
vast, vast majority of cases the answer is, and will be, 'no'.

Thus cases will be rare rather than common. Certainly less common than, say,
TVI issues in the early years of television. (We all seem to forget that many
predicted the downfall of ham radio when tv came into common usage.)

As for SWL'ing, I am not sure, given the redundancy of bands and the internet,
that the broadcasts will be compromised. Is there evidence for this? Why is
this important? For example: other than some indescribable indulgence, is it
critical to hear Radio Tuva on the 30M band? Is the 40M band good enough ?

Would you be so kind as to ID? This screen you hide behind seems rather
compromising, and unnecessary.
