Broadband over Power Lines has been approved for a NPRM by the full 5
commissioners of the FCC. What this means for all short wave listeners is that once BPL is deployed a SWL is not protected by any interference caused by BPL transmissions. SWL's use part 15 devices and most accept any interference. If BPL interfered with local Radio or TV broadcast then the licensee of those stations could complain, however I doubt if any SWL in America will be able to get a international broadcaster to complain to a utility company about BPL interference. Basically this could lead to the death of shortwave listening and ham radio is equally threatened. Ham radio and CB operators will face irate neighbors who have their BPL Internet connection interfered with by transmissions. I can easily see enraged neighbors calling their congress person complaining about the 'CBer' wiping out all the Internet connections in their neighborhoods and congress quickly passing a law placing the burden on the Ham Radio and CB Operator not to interfere with Internet BPL. The FCC has allowed the beginning of the end of HF operation by allowing BPL to use HF frequencies.

It may work, but I question how well. One reason for granting permission is
to extend internet to rural areas that can't be served by conventinal means. This Summer may prove whether it will be feasible or not. If the energy grid goes down, no one will be surfing on power lines. There is concern about the stability of the power grid and its vulnerability to terrorists and wackos. I question surfers' personal safety and security using a power line setup. I already have a great deal of interefernce all up and down the bands from some sort of constant computer signal in the area - power line transmission does not turn me on. It seems like recycling old rickety infrastucture to use new technology whose needs are not going to be well met by a means of transmission that is insecure and unreliable. Beside that, increasing the traffic on circuits already maxed out by spam and hackers is going to do nothing good to existing users of the internet. The Service Providers already lack sufficient bandwidth, and increasing traffic will not improve service if the providers cannot provide enough servers and secure enough transmission lines. To crash a program or a computer it is only necessary to gable enough ones and zeros - maybe even just one. "Keith" wrote in message ...

Well the way I look at it is, that if it makes the spectrum useless, then I
will use my gear for nothing more than a 24 Hour Beacon. Which in turn should make BPL pretty much useless. Not worried about the neighbors, the will never know whats causing there service to fail, and sooner than latter they will drop the Service. |

I hate to say it, but I'll probably put up a 10 meter beacon. Of course,
FCC rules state using the minimum amount of power necessary for communications. This means searching out folks on the internet that are perhaps 40 miles away and you'd need some 'reasonable' power on 10 meters. Best to use a horizontal dipole. A vertical will reduce BPL interference in both directions and a yagi would reduce your horizontal signal spread (as well as aid communications). 100 watts or so ... I wonder what would be most effective? AM/SSB/FM? Again, you simply increase power on the mode selected to obtain decent communications. You also happen to choose a mode that would tend to disrupt BPL. Of course, if the power companies do happen to filter to protect amateur bands, they also will protect themselves from signal ingress. Obviously, they are smart enough to stay away from the commercial FM band, but I'd bet there will be problems in fringe areas for channel 2 and 3 television. It will be interesting to see how it plays out. 73 from Rochester, NY Jim AA2QA "WA8ULX" wrote in message ...

You miss the point. I'm interested in showing how this BPL is a two-way
street. Beacons are legal on 10 meters. 6 meters would also likely be effective. I'd prefer not using 20 meters for a 40 miles circuit which would require a considerable signal and also cause that signal to be stronger thousands of miles away. I'm interested in a band that isn't open and working someone far enough away to require 50 watts or more. That is how you demonstrate the two-way possibilities of BPL. Ya keep it all legal. Daytime 160 or 75 meters would also require a fair amount of power for a 60 mile or so circuit, but you wouldn't generate the e-fields which would bother the BPL as much (but, on second thought, those power lines are long and would tend to pick up quite a signal). You have given me another thought here ... ![]() You see, if an unlicensed transmitter is going to put some electric field into my receiver, I simply want to return the favor - with interest. 73 from Rochester, NY Jim AA2QA "William" wrote in message om...

Serving the rural areas happens to be the biggest marketing lie in the whole mess. It won't be econmically feasible in the rural areas. There simply are not enough customers per square mile to justify the amount of equipment (e.g. signal boosters and transformer bypasses) that will have to be installed. Dee D. Flint, N8UZE |

You "know" all those technical things from experience and learning how to twiddle a morse key in amateur radio? :-) Please point to a trade-technical press with detailed technical information on any of the proposed BPL systems. Detailed descriptions including signal levels, not computer simulations based on assumptions. LHA / WMD |
