If the BPL signal can be shown to be below the published Part 15 guidelines, it is deemed acceptable, EVEN IF IT COMPLETELY WIPES OUT RECEPTION on the affected ham bands.

I re-read the report and order of October 14, 2004 that ammended Part 15 by adding Subpart G and find no such reference. Perhaps there's another modification that you know about.

While FCC 04-245 Report and Order, In the Matter of Amendment of Part 15 does make some specific statements about emmission limits, it does not nullify or mitigate the Part 15 requirements of non-interference. In fact, it adds the requirement that the BPL systems must be capable of some level of attenuating signals to avoid interference with licensed services (for less than 30 MHz must be able to attenuate at least 20 dB below Part 15 limits). It further specifies how they are to respond to interference complaints. However, it does not specify that it is sufficient to meet the 20 dB attentuation when there is a complaint. In fact, as far as I can tell, it remains that as a Part 15 user they must not cause harmful interference to a licensed user of the spectrum.

If you believe otherwise, please indicate where it says that meeting the emmission limits is sufficient.
