Rob, On the X10 web site it does say that neighboring houses can be affected by your X10 signals if they also have X10 using the same channel (house code). A friend here in my office and I recently purchased the new FireCracker kit and have been having fun randomly turning each others lights/fans on/off. Incidently, the Firecracker kit includes a RF transmitter module that plugs into a PC serial port and operates in passthrough mode somehow (you can hook a modem or whatever into the back of the module and the modem doesn't know the X10 module is there). Imagine my surprise when I pried this transmitter module open to find a surface mount 12C509 on the tiny breadboard for this unit. The whole unit is basically a breadboard with the PIC, a few other surface mount components (resistors and caps and whatnot), and a couple of small loops of wire (antenna?). Would I ever like to get a look at the code for that! However, I am sure that it is code protected and I WILL NEVER crack or otherwise copy someone elses hard work without their permission. Maybe one of the RF gurus on this list can give us a high-level explanation of how you can make a transmitter out of a PIC and a loop of wire.
