TV stations aren't concerned (yet) about BPL because the signal levels needed to receive snow free television are on the order of 50 times higher than those to receive a listenable signal on a good HF receiver (20uV for HF, and 1000uV for television).

If you're saying most TVs are getting much higher signal levels than most radios, I'll agree. But BPL radiation will go up with frequency and will be much higher at 60 Mhz than it will be at 5 Mhz. In addition, most homes are now wired for cable, which is much better shielded than your basic HF antenna. That may or may not be true in the proposed BPL areas. BPL is supposed to be most attactive for outlying areas without DSL and cable acess. Interference aside, BPL would be a slick solution if it's reliable. However, there hasn't been much evidence that BPL can deliver wide bandwidth to a significant number of customers over a long period of time. Frank Dresser |

Speeds lower than typical, contemporary DSL/Cable with more susceptibility to intereference. To note, it wont really be able to increase its throughput once big companies like Verizon have mostly implemented their FIOS (fiber) service at opening speeds at 5 Mbps downstream, 15Mbps and 30 Mbps downstream options as well. The techonology wont allow for it to be competitive business-wise. This all works against the money greedy pigs at the FCC/Power Companies' lies about QRM on the RF spectrum slated to be used. |

BPL will interfere with SW and TV signals BEFORE they get to the antenna. I don't think BPL will cause "snow" as we know it, from all descriptions the interference is a bunch of clicking and buzzing noises. Try watching TV while the picture is cutting in and out because of BPL. I think that once BPL is shown to affect TV (as I believe it will) the networks will be falling all over themselves to protest. ----== Posted via Newsfeeds.Com - Unlimited-Uncensored-Secure Usenet News==---- http://www.newsfeeds.com The #1 Newsgroup Service in the World! 100,000 Newsgroups ---= East/West-Coast Server Farms - Total Privacy via Encryption =--- |

In addition, most homes are now wired for
cable, which is much better shielded than your basic HF antenna. not true. My radio scanner proves that the cable companies are not shielded. Even when driving to the next county over, which is a different cable company, I still pick up the cable tv transmissions on my scanner, through the air. And even driving to the next city over, which is a third cable company, I still pick up the transmissions through the air. NOne of them are shielded. It ruins trying to listen to the communications bands on a bunch of frequencies above 30 MHZ. Reporting it doesn't do any good, as all of the cable companies refuse to fix it. |

Tell them you're getting their programming for free because they have leaky systems. That'll change their tune real fast. Time Warner locally has been well known for being exceptionally greedy about that sort of thing. --Mike L. |

HF, and 1000uV for television). In addition, most homes are now wired for
cable, which is much better shielded than your basic HF antenna. In addition to the cable leak interfering with listening to communications above 30 MHZ, it also interferes with listening to AM broadcast and shortwave bands even worse because of all of the buzzing caused by it on AM and shortwave. Just to make s ure that the problem wasn't in my radio, I also checked my other radios (AM and FM bands). The buzzing was still present on the AM radio on every radio I have. So the problem was definitely not in my radio. When I do get far enough out oif the area, the buzzing stops and AM can be picked up mnormally. However, I normally don't drive out of the area that far. I usually stay either at home or within the area. |
