Stuart,

Thank you for shedding more light on the details of the testing, and results received in Austin.

Already, one licensed mobile operator tester has reported that in the core of the test area, reception of NIST standard frequency station WWV is drowned out on portable receivers. This is not good, as WWV is widely used by scientific and ham radio operators and Short wave listeners as a calibration standard for their reception equipment. Some of the ham bands were adequately notched as is required of BPL to avoid interference, but some were not; showing just how flawed presnt BPL technology is. BPL defies the physics of radio propagation; you do not put radio signals onto a medium, (open wiring) and not have problems with the signal leaking off the wires as they act as antennas. One of the challenges to BPL is to operate without creating interference to FCC licensed users of the short wave spectrum. Unfortunately overlooked by the FCC, is that the short wave receiver user, who has a free right to listen to any frequency, has no easy way to overcome local interference by the leaky radiation of BPL carrying power lines. The BPL system does not include a way to sense when its power goes astray, and intrudes into the reception zone of other users of the short wave spectrum.
