![]() "recalcitrant ham op" wrote in message ... "opcom" wrote in message ... This was posted to ARLI, I don't know how many subscribe, but in spite of the numerous comments against BPL (transmitting wideband internet data over power lines, which will destroy the HF radio spectrum), the FCC seems disposed to encourage it anyway. evil! evil! just look up BPL on the web. T the noise from the radiated signals trashed the ham bands thoroughly. I guess you never heard that money talks and bull**** walks eh? Did you *REALLY THINK* that a couple hundred aging HF operating tightwad ham radio operators are going to stop an emerging technology that will conceivably network home appliances to the internet and be worth $BILLIONS$ in potential revenue ?? Jeezehus-H-christ...get F-N real !! Get your facts straight. There are 300,000+ hams licensed to operate HF and another 300,000+ hams licensed in the VHF and higher only category. Note that BPL will also trash 6meters and 2meters. Dee D. Flint, N8UZE |

Power lines are right up next to the rigs. The RF from the radios will trash the BPL. Probably by causing drop outs and adding lots of extra delays. Basically it will make BPL useless anywhere near a ham station. Dan/W4NTI OK, let's say it does slow or even stop BPL near a ham station. Why wouldn't the FCC restrict amatuer operations around BPL areas? Right now and under the new power level proposal, BPL must meet Part 15. This means that it legally cannot cause interference to any authorized or licensed radio service and must accept interference from any authorized or licensed radio service. Therefore any problems in BPL must be resolved on the BPL side under current regulations. It would require changes in both Part 15 and Part 97 to restrict operations around BPL areas. Plus don't forget the non-ham spectrum users. The FCC will have a heck of a time telling commercial AM radio, FM radio, and over-the-air TV broadcasters to shut down. Dee D. Flint, N8UZE |

Yes, that's the question. If a currently legal amatuer radio operator could shut down high speed internet access for a given area, is there any reason the FCC couldn't change it's current regulations, and put in new restrictions on amateur radio? Plus don't forget the non-ham spectrum users. The FCC will have a heck of a time telling commercial AM radio, FM radio, and over-the-air TV broadcasters to shut down. Dee D. Flint, N8UZE I'm sure the FCC wouldn't restrict any of that. The TV networks, radio networks and all the people who watch and listen won't let them. Frank Dresser |

![]() "Dee D. Flint" wrote in message .com... Well interference caused by hams will be small potatoes compared to the power that some of the commercial broadcasters are allowed to use. That will compromise BPL over a much larger area than any ham station ever could. If BPL ever comes to my area, I'm within a few hundred yards of some of these broadcasters so the BPL users will never even notice my signal since they'll be constantly torn up by the commercial stuff. Dee D. Flint, N8UZE I expect the BPLers would trap the broadcast frequencies. If the interference from established broadcasters is still too high, they simply won't offer service in that neighborhood. But I don't think RF is the biggest problem for BPL. Overhead power lines will only intercept a small percentage of the RF, and re-radiate at least half of that. I think noise sources plugged directly into the power line are going to cause far more problems. Frank Dresser |

If one of the neighbors has welding equipment, that can really put a lot of noise onto an electrical line. It takes a lot of filtering to keep that out of your radio and no doubt would do a good job of interfering with the Internet signal. Dee D. Flint, N8UZE |

Capt. Carl would you please make BPL go away like you did the real Hams.
Thank you. 10-73's! |

Don't know about BPL, but VDSL goes from 138KHz to 12MHz and has 4096 tones. Not as much potential for a problem, as it's all twisted pair rather than power lines.

Here's what we do --- we built a (legal) KW rig into a van, install a vertical- radiating antenna, cut out the roof and replace it with a fiberglass sheet.

Yes, I know Ashcrofts boys are reading this --- Hi, muthers -- I live at the callbook address. Bring some beer when you come visiting. N4GL Do you mean the way CBers made channel 5 unwatchable 25 years ago? I don't know much about BPL, but I think the TV analogy might hold. Given the bandwidth of BPL, there must be dozens, maybe hundreds of channels on the powerline. Can every one, or most of them, be wiped out? I'm thinking somebody came up with some pretty robust ways to deal with interference. But what if it does stop BPL? BPL isn't being backed because it's a technically elegant system. It's being backed by politics. Rural areas were critically important in the last Presidential election, and any candidiate would love to say something like "MY OPPONENT IS STOPPING ONE FORM OF HIGH SPEED INTERNET DISTRIBUTION ON BEHALF OF HIS PALS IN THE TELECOMMUNCATIONS INDUSTRY, BUT I PROMISE TO BRING IT IN, RIGHT ON YOUR POWER LINE, AS SOON AS I'M ELECTED!!" Of course, that would be a political misrepresentation, but politicans get away with worse every day. Politics turns into a numbers game. How many politicians or bureaucrats are saying anything negative about this goofy scheme? Politicians may not know physics, but they do know how to count. Frank Dresser |
