Re: X10 signal problems...

While "line noise" gets blamed for many X-10 woes, I suspect that signal
attenuation is more often the culprit. Have you added any electrical devices
recently? Have you tried turning the heaters off before dawn to see if they
are a factor? You may actually have to unplug devices to find a signal
attenuator which may be due to a capacitor across the mains.
