Search of the FCC database shows that the
remotes and sensors, use the standard X10
frequency of 310 Mhz. Note X10 Transmitters
are not high tech. Tests have seen the
frequency of some devices be +- .750 Mhz. or
more from 310 Mhz. Some Hunter Remote Fans
also use the same 310 Mhz. just to add spice
to the mix.
