Whether you use X-10 or some other Power Line Control (PLC, eg: UPB,
INSTEON, various flavors of ethernet over powerline) you might find Jeff
Volp's suggestions helpful.

Key in my opinion is to have a map (i.e., schematic, or diagram) of your
home's wiring so that you can understand the relationship and geometry
between devices, noise sources, signal extenuators and AC phases.

A strategy that would apply to all these technologies that IIRC Jeff has
applied in his house to X-10, is to put the PLC devices on one phase and
as many of the noise producers and signal suckers as practical on the
other and _not_ use a phase coupler.

Physics and the US and Canadian electrical codes dictate that one
shouldn't move loads around willy-nilly in the AC power distribution
panel, but in my case, I could make significant improvements taking care
to keep the loads balanced and compliant with the NEC.
