This is actually a good thing. The FCC was trying to push a technology that does not work well, interferes with others, and costs much more than some other ways of getting connectivity. Even if the Amateur bands can be notched out, the other frequencies suffer. There are a lot of other communications in the range of frequencies that BPL wipes out. The FCC needs to rethink their stance and pay attention to the laws of physics. If BPL is allowed to exist I believe there will be a time in the future we will regret the down side of this technology. In the places it is being used now there are a number of interference problems that keep different services either off the air, or make the use of that spectrum damn near impossible. There is also another side to the story. Licensed equipment transmitting in close proximity to a BPL system can shut down the BPL connection. The bottom line is BPL should never have been adopted.
There are better, more effective and less costly ways of getting connectivity without polluting the HF spectrum.
