Possibly poorly wired HPS lamps ballasts...about a megawatt worth.
Look closely at the windows and see if there is a shadow box with an old woman sitting in a rocking chair in the picture. These are used to stop irradiating the neighbourhood with grow light.
Or you could check to see if your neighbourhood runs a few degrees warmer than the TV forecasts.
You may have noticed the rugs all in the garbage a few months back or junk running down the side walls from the soffits where the condensation has been pumped into the attic. Now the skunk you thought was in the neighbourhood will disappear, also.
Or their names where Ngu.......
For any of those still following this thread, the interference finally stopped after the Section 8 house across the street was raided by 5 vans full of policemen at 5 in the morning. I'm beginning to suspect they had the house under remote radio surveillance of some sort that interfered with the X-10 radio signal.
When I woke up, I saw the vans pulling away but fortunately I had the whole thing recorded on my CCTV system (although it was pretty grainy). At precisely 0500, five dark blue-green vans pulled up in front of the house across the street with their headlights out. Then, a huge crowd of approximately 25 agents in black tactical uniforms poured out of the vans, along with a K9 unit and surrounded the house. They finished up at 7AM when a fleet of local county police arrived. Since then I haven't logged a single bogus X-10 RF command and God I hope it stays that way. Of course this all happened *after* I spent a considerable amount of time restructuring all my X-10 RF gear. )-:
I believe it was a drug bust because people would come to their house at all hours of the day and night and never stay more than ten minutes. Also, when they weren't home, people would sit outside their house in their cars to wait for them to come back. People *still* drive by the house slowly as if they are trying to figure out where their drug connection went. Two of my neighbors had complained about something suspicious going on and I complained to animal control that they had a very angry pit bull, which nearly killed my dog and which are illegal in my county. I guess it does pay to complain.
The oddest thing about the bust was that just before the vans arrived, the Section 8'ers turned on their front porch light. I can only assume they thought another customer was coming by. I'll bet they were *really* surprised to see a squadron of agents at the door. Another side benefit is that I can park on the street again. They had a collection of beater cars that would make a used car salesman envious, parked in every available space, on street and off, leaking more oil than the Exxon Valdez.
