If people need internet in rural area... "If..." ?? Geesh moo, excuse me. ...let them dial in like I do. 1) www.wildblue.com Two-way satellite coming mid-2005+/-. Anik F2 is up now. 2) Wi-Max Huge range and very high speed. Coming soon to a tower near you, or even not so near. 3) Also, advanced DSL can now reach much further and faster. |

"Theplanters95" wrote in message ... I have an unanswered question about BPL. Where I live has a very old power line system, full of splices and corrosion. How will splices affect the 1) the internet signal and 2) RFI? Randy ka4nma The internet signal will be crappy and subject to interruption by static from all kinds of sources. RFI generation will be severe. I do not know whether the splices and corrosion will make it worse but it certainly won't help matters. A lousy splice could well act as a completely non-linear diode detector and spew even more garbage everywhere up and down the whole RF spectrum. It just keeps getting worse. As to power line physical specifics kindly consider: To to a large extent the radiated interference the BPL ISP's might bless us with, if it ever gets off the ground, is dependent on the physical realities of the line configurations they use. Roll back decades ago and the phone companies rather easily beat their interference problems (crosstalk for one) eons ago by using twisted pairs of conductors to move comms along their wires. Twisted pairs of conductors are generally inclined to reject incoming interference and equally are not particulary inclined to radiate whatever signals they might be transmitting from here to there analog or digital yes? Of course. Goes back to some guy named Maxwell, has something to do with the 3D electromagnetics right-hand and left-hand drive ya batty "rules" he "discovered". So it's become quite obvious to me that BPL and HF ham radio could co-exist quite peacefully on the bands after they install their 3Ø 13Kv twisted pairs. Dee D. Flint, N8UZE w3rv |

You mean like it got "took" before (as you may recall, no votes above 9 counted)? In the last election cycle we had a close race for Senate between Maria Cantwell (D. challenger) and Slade Gorton (R. incumbent) and it was the Absentee Ballot from the rural counties that gave Slade the boot and that final count took some several weeks (following his concession). In fact, the final count hardly saw a ripple in the ballot calendar. If you consider the Oregon vote, it is 100% Absentee Vote. Today the new registrant count has pushed past 1700 with the focus moving back into the well-heeled suburbs. Same enthusiastic participation in a traffic of SUVs following me through the parking lot while I was looking for the designated parking place (I'm driving a 25 foot RV style mobile registration office for the Office of Elections and Records). It is not without its amusing moments, and its irritating moments. Yesterday had me in a tide pool of University students (their moment to catch up on registration once back on campus) and they were quite inventive on how they thought voting should work (with some as lazy as their parents in the 'burbs). Back in the 'burbs today and this frantic b**ch demanding guarantees for her mother (at her side). There was nothing I could offer that was satisfactory and she dominated everyone's time to get her agenda cleared first. I put up with that just so far and cut that loose; gave my spiel (the facts of life and how to cope); and her mother shook my hand while daughter went into melt-down. Another fellow with a thick accent asked why we didn't check identity papers. I explained that if we got more than 1 signature from the same address and the same voter, he would be visited post-haste. He then asked what kept a foreigner from voting, I responded "5 years in the penitentiary." There's your joke. 73's Richard Clark, KB7QHC |

Roger Halstead (K8RI & ARRL life member) (N833R, S# CD-2 Worlds oldest Debonair) www.rogerhalstead.com Power lines are fair at delivering low frequency and high power. At HF they aren't so hot. So while you have the leaky, degraded signal with the dubious convenience of being placed from the HV lines to the other side of your line transformer (and let's just hope that has been worked out to be safe) wouldn't it just make more sense to get the fast signal from the proper source? Going right by your house.... BPL is the industry equivalent of putting bicycle tires on a top fuel dragster. A triumph of politics over technology. - Mike KB3EIA - I agree that the power companies can't couple to their intermediate distribution lines, since coupling across the next set of step-down transformers is poor. I was thinking that the power companies will have to run fiberoptic to the customer side of each of their lowest-level distribution transformers. (As an example, in my case, my residential power feed is a 240 VAC line that is parallel shared with about a dozen other residences. This 240 VAC is created from a 16 kV to 240 V transformer.) The power service is already "right to my home." OTOH, the 16 kV distribution feeds are not always "running right past your home." (True, the 16 kV lines do run past some homes, in order to get to an efficient feed point for the 16 kV to 240 V transformer. Some people have their power flow "past" them, at 16 kV, only to come "back" at them at 240 V.) BPL, as I understand it, will be radiating from a huge number of these 240 V residential clusters. Since the power company will have to use fiberoptic to get to their step-down transformers, it seems like they should use fiberoptic for the last leg too. (And then they wouldn't need a fiberoptic-to-240 V coupler at the transformer nor the 240 V-to-coax coupler at each residence.) Ed wb6wsn |

You just picked out an
obscure, already known, form of antenna, and "discovered" a new more stylish name for it. MK That life was so easy:-) No Mark, I'm afraid (for you) there's more to it than that.. You have taken two statements that relate to different things, and tried to confuse people by combining them as one. I believe the history of self similar antennas has been well documented in my publications, and the relevant excerpts are publicly available. In any case, this is a BPL thread and you and I have already expressed our thoughts on that subject. 73, Chip N1IR |

see it, you really didn't "discover" anything. Yes, I understand that you feel this way. The facts are different, as is the reality; both of which have accurately shaped the global perception. 73, Chip N1IR |

And they're going to supply me with high speed Internet over the same
wires? Those 60kV twisted pair lines are on order :) -- KC6ETE Dave's Engineering Page, www.dvanhorn.org Microcontroller Consultant, specializing in Atmel AVR |
Hi Roger, we're really too close to need the internet--we should be using smoke signals instead. I'm in Mt. Pleasant, 26 mi from you in Midland. I was licensed in 1933 as W8KHK, and from then until 1940 I was the only ham in Isabella County. I live in DeLand, FL from Nov 1 to May 1, and in Mt. P the rest of the time. We should meet some day. Did you know the late Paul Woodland, W8EEY? He was originally from Alma, but moved to Midland, Bookness St off Eastman, after WW2. I'll be going through Midland tomorrow to pick up my XYL at MBS, but won't have time then to make contact with you. Guess it'll have to be next year after we return in May. C ya later, Walt Maxwell, W2DU |

I took a one week long course at their facility on the theory and practice of partial discharge testing. There were about a dozen students from various companies in attendance. One of them was a fellow from Canada who had owned his own cable manufacturing company, sold it and was then a consultant for the company. They manufactured HV coaxial cable for power transmission. I learned that many islands get their power from mainlands via underwater lines. Today, coax lines rated to 400 KV are not uncommon. Keep that in mind if you want to QRO :) |

As someone who deals with business cases--daily--I find it suddenly amusing that many hams--present company aside-- think they know anything much about it. I can't wait to hear conversations on 75M about 'entry barriers' and 'crossing the chasm' and 'risk management'. Sure beats 'how's the weather?' 73, Chip N1IR |
3) The FCC has taken careful and measured steps to assure that US amateurs
remain with the enjoyment of the HF bands, given the sharing of spectrum with BPL. What spectrum is to be shared? The BPL advocates are asking the FCC to relax radiation limits. How is that sharing? |

So why did the FCC comment system reject (multiple times) my comments and these
questions about bpl? If you look at the bpl test areas, none of them are in rural areas. Come out to where I live and you will found rural on top of a 6200 foot mountain with a 10 percent grade to go up and down. Randy ka4nma |

"Mark Keith" wrote in message om... sideband wrote in message I'll be the first to admit I have things to learn, and I'm no expert in any one area. I do know what I've experienced with BPL, and it's not been pleasant. Just ask the folks around the Orlando, Florida area... Their BPL tests can be heard all the way across the state in Titusville, and so greatly that it interferes with communications. Money talks, and common sense and real world reports take a walk. In most cases anyway. Some companies have already tried and discarded BPL. Problems o-plenty. Maybe others will see the light. The dark side has won a major battle, and Darth Chipster gloateth o-plenty, but the day is not lost yet. My R2 unit, "henry 2k console model", is jumping around beeping and squeaking just itching to join the battle. If they attack locally, I will give them sporadic shots of my BPL death beam via my various elevated radiating devices. I'll have them locking up like a J38 model speedsters hitting a canyon wall. The F.C.C brass should be flogged with leather whips for the obvious disregard of the currents users of the HF spectrum. It's all about money...Nothing else. All the reports of problems with the systems were ignored. "Except by some owners, who dropped out of the BPL testing" Also, many claims are pretty hokey...IE: they claim that they can null out problem frequencies, IE:, aircraft, etc, etc. But I hear of problems doing this. I hear it's not really that feasable if they want to maintain proper operation, and I also hear it doesn't really cure the problem, as the "nulling device" is not far from the user. Take just aircraft alone...We are talking nulling say 2-3 mhz, 6 mhz, 8 mhz, 10 mhz, 11 mhz, 13 mhz, 17 mhz, 21 mhz, 27 mhz, just for a few...I may have missed some military bands, etc... I have heard of no notching plans for amateur bands, so I guess we have to go to rf noise hell...:( I bet the system will work great with all those notched holes...Not.... They still will be radiating those freq's on the main lines I would think. It's the biggest money grubbing farce I've ever heard of. Heck, with my radios and antennas, they could probably be blocks or even miles away, and I could still hear it. The Florida experience backs me up on this. I'm not just barking at the moon. Bye bye weak DX....Bye bye weak aircraft signals. Bye bye any rf weaklings...QRp will be extra fun being half the country will probably soon have their ears plugged with digital spew. But, I bet they will hear me too, if the leakage is that bad...:) It will be a bad day for the empire if my R2 unit joins the fray. I'll keep those BPL techs a hopping all over the neighborhood. Remember, most of the speculation is about damage to the hams, etc... But don't ignore the damage all the 1000's of hams and other rf emitting device owners will likely cause them. CB's will have to deal with them also, and you know how nasty signaled some cb'ers can get. I hear some 4-5 mhz wide as it is... I don't think they have really fully taken this into account yet. MK I WISH I had a CBer that narrow. My 'good buddy' puts out a S9 plus from 14 to 50 MHz. Dan/W4NTI |
