Ah, but not wiser. Sad.
I agree with you, I am no wiser. But I've been told many times, over many years, that I'm precocious. You should be happy that I plateau'ed early:-) I'm enjoying the wisdom immensely now that I have the grey hairs to go with it. Not a cause for sadness but celebration, if any:-) Thanks for thinking of me and best wishes. 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 ![]() |

SNIP snip Ed, if my understanding is correct, the power companies will indeed be stringing fiber optic cables. There will be one going right by your house if you are blessed to live in an bpl blessed neighborhood. THe infrastructure must be built. I think there is an impression that the power companies are just going to alligator clip a bpl signal on the lines at the generating plant. It's my understanding they have to not only run the fiber optic cable, but "reclip" it to the power line every mile or so. In the end they are basically running a fiber optic feed, but the power line gets it into the customer's home or business. Yup. The Power lines are really great for mushing up a digital signal. Round off those edges and lotsa reflections. The fiber will be there. What is the attraction of getting your digital signal on your powerline? Heck if I had a laptop, it means I have to connect it to the wall again - unless I run wireless - and then I might as well run wi-fi. I'd really like to see a definitive write up on just how the infrastructure works and the protocol. As has been mentioned a number of times, Both Europe and Japan tried BPL and gave up. Possibly it'll come back to haunt them, but it sounds like they've already found it an unsatisfactory means for high speed Internet connections. The haunting will be on our end, especially if part 15 is rewritten to accomodate BPL. BPL will fail, but part 15 will go on until it is rewritten. - Mike KB3EIA - |

And the rural areas, which BPL was supposed to service admirably, don't have the population density to run that fiber to. It isn't the Hams, it is poor technology coupled with a bad business model. Now if someone wanted to run fiber past my house, and allow me access to it at what I'm paying now for cable.... *then* I'd be interested! - Mike KB3EIA - |

BPL is simply a poor technical solution, and is an interim communications step that should be bypassed. Why wait? People have things to say and see right now. Ultimately, all telecom systems transition. BPL has the good fortune of having an infrastructure and a need right now; tomorrow; and for some time to come. Seize the day! Solve a pressing problem. BPL looks very promising. That is not exactly what the Technology News has to say http://www.technewsworld.com/story/37378.html They basically say it doesn't look promising as a business model and the infrastructure isn't in place to use it yet, except for a few test sites. It's inefficient, expensive to install, and is least likely to serve the sparsely settled rural areas for which it's being touted.

It's a big market and there are lots of ways to play. BPL has a good shot and will undoubtedly have a worthwhile niche. 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? |
