Hello, Here is what the link Avery W3AVE sent has to say about the problem:
73, Bruce WA8TNC ================ Check this out: http://www.broadbandreports.com/forum/r21536214-Ham-Radio-and-ATT-UVerse -IPTVInternetPhone-Problems Avery W3AVE ======================================================== Ham Radio and ATT "U-Verse" IPTV-Internet-Phone Problems During the last 3 weeks, I have talked on the air with 3 different hams who are going through a new kind of nightmare with the ATT U-Verse broadband/HDTV/phone package that has arrived in their neighborhoods. In all three cases, the U-Verse package was of the FTTN variety which is fiber to the node and then twisted pair (copper) for the last 2500 feet throughout the neighborhood. It appears that these FTTN installations are very susceptible to ingress from the HF spectrum between 1 - 10 mHz. According to the hams I spoke with, when they were operating on 160 meters through 40 meters, even with RF levels at or below 100 watts, they were completely disrupting their neighbor's U-Verse installations. STB's crashed, internet and phone connections were dropped, and video was frozen, tiled, or simply went to a black screen. When the affected subscribers contacted ATT, no resolution was offered. It turns out that filtering is not really an option since ATT is sending RF between 1 mHz and 9 mHz right down the copper twisted pair. If you attempt to filter out RF from the HF spectrum, you will also filter out the IPTV - internet - phone signals that are supposed to be there. Some U-Verse subscribers are experiencing ingress from SW broadcasters from the 5 mHz - 8 mHz bands when propagation is really rocking. At this time, all three hams are trying to be good neighbors, one is even attempting to re-orient his wire antennas to reduce coupling, but really, this is NOT their problem. That doesn't mean they aren't getting a little heat from their neighbors though. Has anyone else heard about what is going on with this stuff? It has been over 25 years since I got a knock on the door with a TVI/RFI complaint. Generally, if they were civil, I would listen, smile and nod at the appropriate times, then thank them and offer a QSL card to confirm their 5-9 reception report. After demonstrating that I interfered with none of my own television-phone-stereo equipment, even with a kilowatt of RF, I would escort them to the door and suggest that they call or write to their TV manufacturer or the phone company to resolve their problem. If they were nice, I'd even offer to help them write the letter, or assist with the phone call. But that was it. This just looks like another rats nest ready to fall on our heads. Anyone else hear anything about this issue?
