As of last week I changed my email address to ae6ic at cox.net
This change was necessary because my previous internet provider used
frequencies for the control link to their DSL box which directly relate to
ham frequencies. The result was extreme pixel ghosting when I transmitted.
I tried toroids on the lines, high-pass filters in the TV circuit, different
antennas and shielded feed lines. None of the old "fixes" worked. Then my
son, KJ6JUS, researched the problem and came across the link below. Wow,
enlightenment. Apparently ATT U-verse utilizes ADSL (asymmetric digital
subscriber line) or one of its flavors for link control. The frequencies
utilized by these range from 1.1 to 30 MHz! I switched to Cox and the
problem went away.
Here is the thread on ATT U-verse / Ham interference in case any of you are
experiencing the same problem:

I'm not much on complaining, but this problem opens Pandora's Box. Hams will
be blamed for something we have no control over. Is there a "proper way" to
file a complaint with the FCC?
