Bobby,
I can understand how signal processing and amplification can improve the
proper  detection / triggering from X-10 controllers, but I can't
understand how it could help reduce the false triggering from noise such
as CFL-generated EMI.

If the receivers in each X-10 module have frequent false triggering from
noise, as mine most certainly do whenever the fluorescent lights are
turned on, they remain susceptible to false alarms / triggers even if
the controller signals are amplified.

The receivers still suffer from a poorly designed X-10 signaling code
design, and rely on millivolt-level amplitudes of the 125 KHz signal to
threshold their detectors. In this regard, they should remain as
vulnerable to noise as they were originally, despite the boost in signal
strength for the controller signals they receive.
