[SCCC] U-Verse and RFI

[Bruce Kripton]

Sadly my issue as well.
I'm sure everyone knows this, but it's not the service or carrier, it's the method of signal delivery that's the real issue.
Unshielded twisted pair (or multiples, depending on the "speed" or class of your service) delivery is the problem in general, from the fibre pod to the modem is always a problem in high RF environments, DSL or U Verse customers are going to take hits when the radio is keyed.
Adding chokes or passing the wire in from the street or pole to the modem thru toroids or ferrite might be okay for slower DSL services, but at 10 Mbps or faster speeds, you are going to negatively impact access speeds by affecting the modulation / signaling. 
I really don't have much that's nice to say about Cox or TWC, but it's a shielded delivery system to your home....

I am hanging on to my DSL as my only alternative is
nothing... The homes in this neighborhood are not qualified
for U-Verse.....I kill my DSL with 100 watts. Figure 1500 watts would let
all the smoke out of my DSL modem.....

Are any of you Rabid Aavid contesters using U-Verse and solved the I'll
effects if getting your receiver thrashed plus possibly knocking your
internet off-air when you transmit 1500 watts and antennas are too close to
the unit.

In the past, most hams I communicated with just gave up and got rid of
U-Verse but I don't have that option at the site which has only crappy slow
ATT DSL with lots of dropouts and bad latency at times when trying to
Remote into site.

I heard rumor that there are now several U-Verse modems to choose from but
not sure one can just pick what they want.

If the modem was put into a good Faraday shield and Type 31 mix large donut
ferrites were used on all leads going to from modem, right at the Faraday
shield, will that solve the U-Verse  RFI issues ?
