Before looking for a filter, verify the spurious activity comes from the
phone line boxes.  Unplug both boxes and see if the problem disappears.
Those boxes use the powerline to send signals between the boxes, so it
is possible your X10 devices may be affected.

The only solution to the problem may be running a separate phone line
to the satellite receiver and eliminate use of the phone line extenders.

One way to troubleshoot X10 problems is to unplug devices which are
suspected of causing interference.
