Hmm… I’ve run into a little snag with U-verse….. I’m finding that a frequency on shortwave radio I transmit on causes a problem, knocking the residential gateway off the VDSL connection. It only happens at a specific frequency, which I can’t post, since it is not an amateur radio one and a frequency I use by permission. I did have ladder line running from the radio all the way along my basement ceiling all the way outside and then up to my antenna.
What has helped a little is I placed the tuner as close to the outside wall as possible, and then used high quality coax cable (LMR400 to be exact) to go from the radio, along the ceiling, and then to the tuner. The only ladder line in the house is approximately one foot maybe, and then it is outside. I’m still seeing a little problem.
I wonder if part of the problem is that the coax cable for U-verse has a shield connection that is marginal. The techs say I have a great, low-noise connection to the VRAD, but maybe there is a connector inside that is still giving me trouble. I know they replaced just about every coax connector in my TV system here.
Anyone else run into these problems? I don’t think this is the kind of thing they will help troubleshoot, they would probably say “Why are you running that kind of RF power anyways?” Its only 50 watts of power, and I would think that most of it is staying inside the LMR400 cable….
I’m thinking about getting a field strength meter to measure just how much RF is in my basement, and if there are excessive fields.

I just cancelled my AT&T; U-Verse and switched back to Time Warner cable on 6/9/2008.
I am a ham radio operator and constantly had probelems with RF getting into the residential gateway.
i did not have interference problems with Time Warner before the switch to ATT U-verse and i do not have thme since i switched back to time warner.
The AT&T; U-verse equipemt appears to be operating in the frequency range that hams use know as HF. this plus the fact that their equipment it not adequately filtered causes problems. i had several techs out and we noticed that when RF got into the the gateway, error counts would go into the millions. what is strange is that the error counts kept going up by the millions even when all ham radio equipment was turned off. their concept is interesting, but the design is flawed. we tried all the usual things that hams do to minmuze this interference like grounding everything, applying boat loads of ferrite beads on everything, but in the end the design flaw was too much to overcome.
