Can the XTB or XTB-II/R help with electrical noise problems?
It depends on whether the receiving module can recognize the strong XTB signal above the background noise level. Some X10 devices, such as the higher price Leviton switches, incorporate some form of AGC to raise the signal detection threshold above the background noise level. The XTB or XTB-IIR will certainly help when using those devices in noisy environments. Modules without AGC can be rendered deaf by the background noise, and will ignore the stronger XTB or XTB-IIR signals. In cases like this, the only option is to reduce the noise level so the receiving module is no longer saturated by that signal. Blocking the noise directly at the source is best, but it is also possible to use a custom signal sucker to attenuate broadband noise on a given circuit. Even though that will also attenuate the X10 signal, the powerful signal from the XTB or XTB-IIR should be well above the noise level. I had created a custom “signal sucker” for my testing. It alone attenuates noise from my CFL test cl
