"...X-10 signals over two wires of a barbed-wire fence over a large distance..."

I love it. Sort of reminds me of the guys that used coat hangers (instead of coax) to transfer AC-3. Just because they could. And to make a point.



"...Not familiar with them...[bridges without neutrals]"

Here's an example: [Link: smarthome.com]



"...Whether the surge strip blocks the direct neutral connection is unknown..."

Oohhh. Good point. Maybe I should stick with something like this: [Link: smarthome.com] . But then, neutral wouldn't be isolated and/or surge protected. Hmmm. Wonder what the "right way" is to get X10 signals to the protected side of a UPS is.



"How'd I do?"

Gold star, as usual :-)
