Michael,

Thank you for the quick reply.

I know that it is difficult to put a technical solution in lay
person's terms but it would help me if I understood the terminology.
If you have time, is it possible for you to explain why these
speakers/
transmitter have this problem and how your solution will solve the
problem. I am not familiar with electronics so I do not know what is
an "X-10 line of modules" and I do not understand the "120 VAC lines
to couple the RF to the other line."

Again, I appreciate the information.

Lin



Simply put, those speakers are sending the audio on the electric wires
in your home, over an RF carrier. X10 controls do the same thing. X10 is
basically light and appliance control system that sensd signals from a
keypad or other controller, over the powerlines, to receiver modules
that control lamps or appliances.

Typical North American homes have their electronic service coming in on
two 120V lines from opposite sides of the utility trasnformer (which
don't carry over the powerline RF, typically), sharing a common neutral.

What could be happening, is the other outlet is on the other 120V supply
leg coming in, than the outlet the transmitter is. A passive X10 bridge
(which is essentially a capacitor that couples the on line RF signals
from one leg to the other) may work. It could also be one outlet is too
far from the other, electically, or there is a filter somewhere blocking
the signal.
