Joe:

Take a look at the first post in this thread (at the top of the screen) for some ideas.

I did but that doesnt explain how my transcievers got blown out. They no longer work at all, when I send it the code you can usually hear the click it makes, but no click the module is dead. They blew in two different outlets as well. So I dont think phase discrepancies would ruin transceivers modules. I ask becuase I really don't want to have to buy a fourth module.

Are you sure they are dead and not just playing possum? If you have a “bridge” problem, it could intermittently work like you are stating. It may have worked once and will never work again. Lack of phase coupling can cause X-10 to do some crazy things. Try plugging the module and transceiver on the same circuit (same outlet with a multi extension cord or on the same wall plate). Does it work there or is it really dead? If its dead and you killed 2, that’s interesting.

Has anyone ever measured the signal strength received at a module from:

Transceiver (by way of a wireless remote)
vs.
Computer interface
