Your list of possible noise genarators pretty much cover everything I have in the house, it will be tedious to isolate. However I do have a phase coupler from my X-10 days of allways being on the wrong hot leg, hardwired to the utility power comes into the house main breaker box. All the new power goes back to the same demark. I also have several Access points (2443) and Signal Relays (2442) sprinkled around the house in the old and new parts to make sure the signal is strong.
