Lately we have ben getting a lot of noise on channels 5 & 6, usually
at certain times of evening and night; almost never during the day. This interference usually lasts about fifteen minutes, then cuts off. Is this something caused by my neighbors? Can I call the FCC to track it down? It's really ****ing up my videotapes. Ron |

The timing, would correspond with a 9-5 worker, and does it use the radio most often on the weekends ?? Are you not on CABLE ??? in the 21 Century ! As I understand it the FCC will Terminate Analog TV Service in about 14 months anyway !! Yukio YANO |

The FCC will send you a color broshure detailing several mostly useless options. Basically, unless you can identify the source, and they're obviously in violation of some rule or reg, you're on your own. Best bet is to identify the source of intereference with a directional antenna and a portable spectrum analyzer. If that's too messy, try running around the neighborhood with a battery operated TV receiver and look for the strongest areas. It's going to be quite a rush because you only have 15 minutes to find the source. Assuming you're talking about over the air channels, and not cable or satellite channels: CH 5 76-82 MHz CH 6 82-88 MHz Hmmm, you probably can also hear it at the bottom of the FM broadcast band. With the information you've supplied, I can't even begin to speculate what the RF source might be. A 15 minute single run in the evening kinda sounds like a microwave oven cooking dinner. However, those operate a 2400MHz and are unlikely to cause problems on TV ch 5 and ch 6. "Certain times of evening and night" implies that you know those times. Could I trouble you to disclose them? Also, any particular pattern on the TV screen? Anyway, if you don't have the equipment or transmitter hunting skills, try asking for help from the local ham radio operators. Incidentally, video tapes are kinda like old technology. You might want to look into recording the shows on a hard disk with a DVR, or a DVD burner. -- Jeff Liebermann 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558 |

They said, well, go talk to him yourself. We don't enforce things like that. |

"Jeff Liebermann" wrote in message .. . Incidentally, video tapes are kinda like old technology. You might want to look into recording the shows on a hard disk with a DVR, or a DVD burner. But that won't solve the interference problem. Of course not. It also won't balance the budget, end hunger, or supply the meaning of life. That's why I added it at the end and prefixed it with "incidentally", which means it's not directly relevant to the problem at hand. I've been slooooooly transcribbling my VCR tapes to DVD and donating my VCR's to the thrift shops. The local rental places hardly have any VCR tape on the shelf. While not totally dead, VCR tapes show all the signs of impending obsolescence and may soon take their proper place along with reel to reel, vinyl disks, and wax cylinders. Incidentally, I do some wi-fi interference hunting and have learned a few things from the exercise (literally). Besides direction finding being somewhat of an art instead of a science, knowing the characteristics and timing of the interference will often point directly to a culprit. That's why I asked for better time of day information. http://wireless.wikia.com/wiki/Wi-Fi#Interference These are not applicable for ch 5 and ch 6 interference, but offer some clue as to what is out there. I kinda like the image of a high power CB transmitter. The problem is that a 15 minute "broadcast", with no back and forth tx/rx exchange, doesn't really sound like the typical CB user. I would expect something like 30-60 second or less transmissions, with perhaps an equal time to receive in between. This would go on all evening. -- Jeff Liebermann 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558 |

They said, well, go talk to him yourself. We don't enforce things like that. All too true and correct. From recent experience, the FCC will do nothing unless either the correct politician is involved, or that it involves national security (terrorism). We were getting inteference from fishermen operating "modified" marine, ham, and commerical radios. When in the area, they would severely interfere with local ham repeaters. The FCC did nothing. However, at one point, they landed on one of the channels used by the local sheriff. Suddenly, there was interest, action, etc. The result was one person in a van, shows up in the middle of the afternoon (when the fishermen were not active), does 30 minutes of listening, doesn't hear a thing, and turns around to go back home. Upon investigation, it seems that he was only allocated enough funding by Dept of Homeland Security to make the one afternoon trip. So much for the war on terrorism. I have other other horror stories, but that aformentioned is the most recent. Not only does enforcement require politics and terrorism, but money is also a great inducer. The FCC does not directly enforce a "notice of apparent liability" (which incidentally is forfeiture without a trial). That job goes to the justice department, which simply isn't interested in collecting fines that cost more to collect than they collect. So, the FCC has gone on a concientious program of ever increasing fines, sufficient to get the attention of the supremes on charges of "cruel and unusual punnishment". The JD is not going to collect a few thousand from your neighbor, when they can go after broadcasters and cellular providers, that take in millions. See the amount of the fines at the FCC Enforcement Burro web pile: http://www.fcc.gov/eb/ http://www.fcc.gov/eb/FieldNotices/ Anyway, tell your neighbor that the feds monitor home electrical usage and that anyone using unusually large amounts if probably growing drugs indoors. Also, tell him that he's running an "alligator". That's a radio that has a big mouth and small ears. It helps if you speak the language. -- Jeff Liebermann 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558 |

Hmmm, I can get 8 hours on a single videotape; what can I get on a DVD disk? One hour of recordings at most, if I had seen rightly the last time I was at Target. Not even comparable... So I think I'll wait till the new tehnologies catches up with the old. :-) As for the time issue, I don't have a schedule of times, just that the problem is intermittent from around 6:30 to 10:30 PM, with no problems before then and none after those hours, but nothing like clockwork. |

One hour of recordings at most, if I had seen rightly the last time I was at Target. http://www.madhousebeyond.com/?mode=docview&view=vhsdvd Length of video DVD recording mode Under 1 hour HQ mode (60 minutes) Around 90 minutes SP mode (120 minutes) Around 2 hours SP+ mode (150 minutes) Up to 3 hours LP mode (180 minutes) Over 3 hours EP mode (240 minutes) If you have a DL (double layer) DVD burner, double the record times. Not even comparable... So I think I'll wait till the new tehnologies catches up with the old. :-) Well, Blue Ray prices are sloooooowly coming down. As for the time issue, I don't have a schedule of times, just that the problem is intermittent from around 6:30 to 10:30 PM, with no problems before then and none after those hours, but nothing like clockwork. That's a fairly wide range of time for a 30 min microwave oven run, but still possible.

If you have OTA, the lates TiVo does anout 160 hours at its basic mode for analog SD, plus can tune digital/HD channels, although it sosts about $200, and has a monely fee. |

In 16 months it will not matter as the analog TV transmitters will all be turned off permanently. I've been using digital TV for almost 4 years now and I can't imagine dealing with NTSC ever again -- and I work in a video post house. True, no tape based VCRs but certainly recorders based on hard disks of which I have 3 units (PCs), often all 3 running to capture HD shows for later - MUCH later as in next summer. No reruns at our house. No ghosts, smears, ringing, noise (except for film grain), 5.1 audio. Bulk storage? I'm using 500 gig USB drives ($110 Fry's) to hold archived shows -- about 120 42 minute shows in HD (commercials removed) per drive. 4 times that in std def. 20 years ago Bill Gates told us TV would be centered on PCs and I thought he was full of it. I was wrong. Time to take the plunge - the water's great. GG |

GG I quit watching TV alltogether years ago and don't miss that waste of time, however for millions of consumers the changeover will be quite a hassle. Even if the converter boxes are cheap, you still need a new antenna and those aren't, nor is installing one trivial for everyone. Cable and satelite customers will essentially be unaffected, but there's a lot of people in rural areas throughout the country who don't have that luxury. |

hi, dont know what software u using, but i can get eight , 45 minute
