I've been fighting the U-Verse battle here as well. I put ferrites in
various places, and moved the antenna G5RV to a different orientation and
only get into Uverse when running over 400W on 40m.
The big problem is with my neighbor. I get into his U-Verse on 20m with any
power level greater that 40w. My suspicion is that the installer used 75
ohm tv coax for the WAN connection to the router instead of running cat 5
cable. I'm planning to re-wire his attic this fall.

Subject: [RFI] AT&T U-verse
A glutton for punishment, I switched our household from Comcast CATV to AT&T
U-verse (TV, Internet, VOIP) when it came to my neighborhood.
It's been about a month now and I've had a chance to do some RFI tests. The
sensitive bands are 80 and 40 M for me. (I don't have 160.) I find that I
can run 100W CW without much trouble, but QRO can break the VDSL
connection. The patient seems to be responding to common-mode filtering of
the low-level VDSL input line. No problems yet noted from the DSL equipment
to my radio. (More info at http://aa6e.net/wiki/Uverse )
My question is whether there has been any careful research on U-verse vs ham
radio. I haven't been able to find any. Maybe someone here has a pointer?
Thanks!
