Good point. X10 devices can be troublesome in a "noisy" environment. There are
many filters, amplifiers and attenuators out there that can greatly improve system
reliability. You may have some luck with the devices sold by SmartHome.com.
Then again, if hubby is inadvertently cooking small birds perching on the elements
with 1500 watts Peak to Peak, you may be out of luck!
I haven't found any small avian corpses under the Yagi . . . But I was raking leaves one time in the back yard while he was OTA and saw him give a squirrel the hotfoot. . . . . . . . :-D
