Go back and check Maxwell's laws. A twisted pair is going to accept interference like any other unshielded wires. However, because of the twisted pairing, both wires will have virtually the same exact interfering signal injected on them. Differential receivers (in the Ethernet chips), can then eliminate the interfering signal. | |

But compare a twisted pair to two conductors spread apart six feet, like a power line. This is the meaning of shielded versus unshielded in the context of the original post. | |

| hopeful I bet that the reason the hams gave their blessing, is because they have been working with the industries trying to develope
BPL. With their input and help, perhaps it will become a reality.
Trust me, as a amateur operator, when the hurricanes/tornados/sky is falling/cellphone towers out/floods happen, amateur operators are usually the only ones who can get information in or out of an effected area.

| Re: hopeful You are assuming that the BPL system(s) would be isolated, away from any receivers, and would not be causing interference by significantly raising the noise floor miles from the power lines. The receiving stations (outside the blackout area) would most likely be using directional antennas from fixed locations (these things can be quite large) and if there is an operating BPL system nearby, reception could easily be disrupted by it.
You seem to be totally ignorant of how ad-hoc emergency communications are set up in these situations.

| Re: hopeful There is certainly more to the BPL issue as it relates to spectrum pollution than you seem to be aware of. As has been stated many times in related threads, a _wired_ technology that pollutes _wireless_ spectrum and does so coincidentally as a byproduct of its operation is BAD technology. While you might be prepared to turn a blind eye to such pollution, thankfully, those better informed than yourself are prepared to speak up against this. If you have valid counter arguments as to why this is an acceptable byproduct of this technology, then please let us hear them - preferably without the demeaning references to the amateur radio community (if you wish to be taken seriously). | |

Without the disaster card to play, HAMS are then just a hobby. This isn't going to get you far in fighting BPL. You can agrue that BPL is only going into areas where broadband is already in place therefore no need for it. I think everyone agrees with that. I also think they are smart by doing it that way.

And there is the point of your mis-understanding.
The person in the affected area is not going to get interference as much as those in a non-affected area. If BPL (using the polluting type) is in the un-affected area, then the HAM in that un-affected area is not going to be able to hear the person in the affected area.

What about along the way? It's not a case of stupidity with respect to the remote stations' locations! If BPL moves into my neighborhood and renders significant portions of spectrum unusable then that's one less station that can participate. If BPL were to become as ubiquitous as its proponents would desire then that's potentially many stations that cannot participate. I'm not prepared to accept _your_ guarantee that there will always be a station in an unaffected area!
Note also that the present abundance of potential stations is in part due to the fact that appropriate, unpolluted spectrum IS avaialable; were that spectrum resource to disappear, it is not unreasonable to assume that the pool of station resources would evaporate - who wants to maintain radios and related equipment that can never be used; how can necessary operating skills be developed or refined?
How likely is this scenario? that's the $64,000 question. With the abundant technical alternatives to BPL (or, indeed the more benign flavors of BPL such as is the topic of this thread) I see little need to proliferate such implementations of BPL that could bring about this situation. | |

| Re: hopeful It seems as if the only point in continuing this conversation is based on whether or not you want to stick to your assumptions or may be willing to read and understand the information and concerns about BPL.
As someone who may not understand or be familiar with the physics and issues involved, it is easy to compartmentalize your argument and your position.
I don't get the feeling that you are trolling, and given the time that others have put into their responses, I believe that others feel as I do.
If you would like to continue this, you may want to explore some of the well-documented concerns related to BPL- specifically broadband over powerlines which does not need, but does produce harmful RF polluting artifacts.
If you understood radio wave propagation, and understood some of the other issues (and affected parties beyond the more vocal ham radio community), you may appreciate the counter-argument.
I'll leave it up to you to ask for such links to this information. Some regular contributors to these threads (which include electrical engineers and people in the related fields of technology) can point you to them.
If you are really not interested, and want to take your stance without understanding the details of the counter-argument, then that is okay, but you may not get the continued interests of some of the contributors here.
I do appreciate honest debate and polite exchange- thank you for that!
Be well,

No 1500 watt transmitters with 6 element beams 300 feet in the air to give 3000 to 5000 watt effective radiated power to cut through the hash, think sub 100 watt units with verticals and long wires close to the ground. I can not believe you are foolish enough to believe that the relief supplies and manpower will perform a miracle and just appear where they are needed without information as to where it needs to go?
Get involved with the national relief groups of the Red Cross, the LDS, Baptist, and Catholic Churches, and others that are involved in this and see what goes on. These groups do not agree with you that no one needs to use a radio outside any piddling disaster area. Or if they do, then they are wasting a lot of money and time getting infrastructure to do so.
Do not know about your cities, but the cities around here are all getting EOCs that have ham radios both long and short distance. Your tax dollars being wasted? Maybe you ought to go check it out and complain to the city council if you feel so strongly about 'outdated' 'worthless' technology being paid for with your taxes? That is also why I want my Ham license, it will be much safer in the EOC than out casing buildings or whatever the disaster is.

I wish you would take a step forward to think potential. In many cases, existing systems, satellite phones and other technology may and does overcome some communication infrastructure failure. There is some neat technology out there today. I do not think any HAM really wishes that it becomes so bad that HAM radio is necessary. Remember, HAM is a line of last resort.
After Hurricane Katrina hit, I did not save any lives using HAM, I did not come to the rescue (however I did volunteer my help in Houston). One little thing I was able to do for someone in Mississippi was to relay a very simple message. A HAM operator, in Mississippi, had a generator and his area was hit enough where cell phones, regular POTS, and power was out. No FEMA to the rescue with a satellite phone for him. However a couple of his neighbors came by and listened to his radio. He was not in any dire need just passing some basic information. I did respond to his station and one of his neighbors asked if a message could be passed to a relative. I took some information and called a relative to let them know that their family in Mississippi was OK. I think the lady at the other end of the phone was about to cry, she was grateful for the information.
If certain BPL systems (and not all) were operational in my neighborhood I would have not been able to listen to the weak signal from the station in Mississippi. However today I can and do something as simple as passing along a message that meant a lot to someone.
Their situation was not life and death but they were in an emergency situation and some BPL systems (again not all) would affect my ability to listen like we all should do. | |

And to the above poster who wanted an Extra-class license to take it down, you don't need it. Generals are allowed the full 1.5KW on HF, Extras just get a little more spectrum. Blast it in the General subband and it'll still go down.

Motorola would probably be more flexible than the current vendors they are testing. Being able to go wireless into a dangerous high voltage area to get data onto the line is much safer and easier than trying to run copper into an area which would conduct high voltage back in the event of a failure. When I was working in cellular in the 90s, a power company was using cellular data links into substations for just this reason. Of course, this could be done with fiber today as well.
Also think of the benefit of being able to "hop over" a severed line with wireless. A pure BPL system will have no connectivity since it depends entirely on the power line for its transport.
"BPL purists" may decry the Motorola system as not being "pure BPL", but I think that's throwing the baby out with the bathwater. The goal isn't to deploy pure BPL, it's to provide a service. Use the right tool for the job, not just a hammer for everything because you want to use a hammer. If a hybrid wireless/BPL system makes more sense and it avoids the interference problems, it's a better mousetrap and companies will beat a path to their doorstep. | |

I guess that we should get rid of buildings and planes...anything to keep down the trained ham radio responders- (oh, I mean nerds!)
Sorry that I just don't feel so embarrassed to show my face because I was summoned as a trained (that is Red Cross, FEMA, ARES, RACES, NYC Office of Emergency Management trained!)emergency communications responder that was given the highest access to cross military roadblocks to serve at ground zero- working with NYPD, FDNY, FBI, military, etc., etc., etc.
What skills do you train for and how much time do you volunteer for the good of your community and country? What emergency response agencies have you trained with or are trained/certified by?
Do you get called in when a plane goes down (like Flight 800), when there is a terrorist attack, a major fire, earthquake, severe weather condition, etc.?
I don't speak hypothetically, as I was asked to respond to all of these emergencies- and then some.
Maybe you live in a part of the country where you don't need to rely or at least feel confident on/in your local responders. If so, please don't be a hypocryte...make sure that you try to talk down those nerds that drive the trucks and cars with those annoying flashing lights and loud sirens.

Bush signs digital TV transition bill
Bill opens radio spectrum to new mobile broadband apps
By Grant Gross, IDG News Service
February 08, 2006
U.S. President George Bush on Wednesday signed a bill that will open up a chunk of highly coveted radio spectrum to new mobile broadband applications and to public safety agencies.
Bush signed into law legislation setting Feb. 17, 2009, as the date U.S. broadcasters must end transmitting analog television signals and move to all-digital broadcasts. The move from the upper 700MHz spectrum band will free up 60MHz for auction to mobile wireless carriers and 24MHz for emergency response agencies.
TV viewers who receive over-the-air signals on analog TV sets will need to buy converters to get any TV signals after the transition. The bill Bush signed includes up to US $1.5 billion in funding to provide two $40 vouchers per household to use toward the purchase of digital-to-analog set-top converter boxes.
The upper 700MHz band would allow wireless signals to travel four to five times as far as existing mobile phone signals, advocates of the digital television (DTV) deadline said. That makes the spectrum valuable for mobile broadband providers and for police and fire departments that want to communicate better with regional counterparts......

| Re: Dumb question said by David :Hey I am glad that Motorola worked with the Hams to give them some technological relief. I believe I read somewhere that a ham system can also be an alternate form of Internet communication, as if the radio cards that were in computers transmitted the signal to the other computer which in turn transmitted the information to the internet.. Yup, IRLP or EchoLink are two of the modes used.

| BPL This ! Don't even need to be a real HAM to induce QRM. Even us 11m bootleggers whistling into a D-104 with a 600w box using 8 6LQ6 tubes well over-driven on good ole' Amplitude Modulation can take out nearly 6 blocks worth of cable TV and cordless phones, re-boot computers within 700 feet, and order a Big Mack from McDonalds 9 miles away ! I would love to see how many megs wide it splatters on a spec-an sometime. That is just my little box and a ground plane. God help that poor micro-watt BPL device on the other side of town ! Don't worry about Uncle Charlie. He's busy at the auction block. Do I hear a CQ-DX in there ?? | |

You just described what I used to do for fun during my high school years...ahh, the good old days....taking out the CATV for 10 blocks around with 1.5KW worth of dirty AM carrier on 11m into a Moonraker 6, making the neighbors turned off fluorescent lights come on..killing the BK & Mac D's internal speaker systems..Creating general havoc and mayhem on the airwaves..
The early 80's were blast..Kids these days don't know REAL FUN.. | |

Moonraker 6
Say no more. YOU are the BOSS !! That was the ultimate dream antenna, and with 1.5kw, I know why the chickens here in Del Rio (450 miles west from you) were laying square eggs during the entire decade of decadance. Nice of you to check in. I was half afraid of getting yelled at by a properly licenced radio operator. Rock n Roll !
By the way, BPL will not be much of a problem. A good week of skip will be enough to convince the white collars at the BPL ISP that short wave is really not reliably suited for broadband. They better keep it Micro-Wave where it belongs ! (Or Else).... | |
