(And for those who can not think, yes BPL would not affect radios in the south since there are/was no power lines, but for those outside the area trying to listen to people in the south, it could degrade the SNR since they still have power and make it hard or impossible to hear pleas for help. But who cares, Ishna Allah)

| Authorities and relief agencies bring their own comnunications. I've read reports where the cellular companies very quickly brought coverage to the areas hit. WiMAX is now being deployed there too. I have doubts to the significance HF radio really played in providing help. (Not the people, the technology) I'd be very interested after all this is done an honest independent study to the positive affect HF radio played in bringing true relief. |

Enough apparently that FEMA filed a brief with the FCC opposing BPL on the basis that it would interfere with necessary HF radio channels during a disaster.
It isn't hard to understand that when all existing in-place infrastructure goes off-line, the ability of direct communications using HF radio are the only thing working.
And let's not think that the BPL interference issue would resolve itself in the area with the infrastructure power failure. In European tests, Italian BPL tests interfered with HF radio communications in the UK. California BPL would be capable of interfering with Louisiana HF radio emergency communications. Imagine the total chaos that thousands of these radiating BPL systems would cause to HF radio!
As of today, the American Red Cross is still crying for additional Ham Radio operator teams with equipment to provide communications to a significant number of shelters without communication capability.
Why not answer the question as to what role HF communications *are* playing in relief efforts by tuning in to the HF Ham Radio communications yourself and monitoring for a while today? Crank up your radio and take a listen while you still can before BPL totally pollutes the precious HF radio spectrum. |

i wonder what kinda radios these Authorities and relief agencies have...
Im pretty sure however that ham radios are able to use it cross continental because HF is a useless old frequency. |

A quick google around of Red Cross doesn't show any mention of
the need for HAM radio operators. If they filed opposing BPL then apparently there were work arounds or did the FCC just didn't care about FEMA? So there are several BPL trials going on right now... I assume you're still chating away? I haven't heard a single report that these trials interfered with communications. |

Don't feed the troll. It is pulling chains to see if it can upset people.

@ev1servers.net | If the level of conversation in HF quickly descends to name calling ... it just gives us bigger doubts it can be take seriously in the time of need. |

Check the Baton Rouge Red Cross page and the ARRL page. One thing about Google, you do have to know how to ask a question.
As to not hearing reports about BPL interfering with HF communications, do a better Google search next time. Several BPL trials have been shut down because of the inability to deal with illegal levels of HF interference. I don't know of a BPL installation that *didn't* interfere with communications, and that also didn't suffer reverse interference from licensed stations.
The FCC has recently stopped taking comments on the BPL issue. FEMA comments against BPL were just one of the many against. Other than the recent Motorola BPL system, I am not aware of any system currently in place that would pass the part 15 requirements as proposed, and these are likely to be tightened. None of the Ambient systems do.
BPL isn't a sure thing yet. |

We mustn't let a fundamental lack of knowledge get in the way of expressing an opinion ... and this is another example of what is fuelling the broadband hype. |

I will let the other responders answer you elsewhere. Heck, I am not an HF ham operator and I knew the answers that you claimed were not there.
If you want to be taken seriously, get off the anon circuit, that is where people hide to troll. You get more respect if people have a solid ID on you.

As those of us in the Amateur community know, we are supposed to use the minimum power necessary to maintain communications.
I guess I'll be causing BLP outages with this.

Not intentionally, of course  , but if I need the power to make contact, I'll use it.
I suppose the lights will dim when I push the PTT pedal. So be it. The glow of the tubes will keep me warm on cold winter nights. |

Wimax will suffer from the same problems that 802.11 suffers that prevent its widespread deployment for access. That is, it's meant to provide service within 1500 feet of the access point. You can't build an ISP around Part-15 access on ISM bands. It isn't going to happen; for if it could, you'd see the proliferation of wireless ISPs using 802.11 on the same scale as you saw dial-up ISPs in 1996.
With that said, BPL will fail because in order for it to survive, it has to work in areas already served by DSL and cable. What DSL and cable DO NOT suffer from is a problem getting bandwidth to the customer. Certainly, it requires a capital outlay, but adding bandwidth there is one hell of lot easier than adding it in a BPL system. Once your power lines are full, what are you going to do, run more power lines?
Worse for BPL, while the FCC is applauding its ability to provide access in rural areas, it's quietly preparing to auction off analog TV channels for Internet access. In any market, there's at least twenty six-megahertz channels available for use. THIS is what will serve rural areas, not BPL.
The argument about the demise of HF is grossly exaggerated. Yeah, BPL will kill it, but that white elephant isn't going to fly long enough for it to be a problem. It makes no difference what the California PUC says, it won't make a dime and will fade into oblivion within the next three years. |

If this is true, then you haven't done even a cursory look.
I haven't updated the list in a while, but:

Cinergy/CG&E in Ohio has large BPL system and is expanding. No inference reported or they would have taken it down. |
