There is no way to send "radio: signals with the CM11A. It can only send PLC
(power line communication) While the CM15A does include a 310MHz RF
transmitter module, the last time I looked, it was not exposed by the X-10
software.

In principle, your idea is sound but you need a way to send "radio" signals
(e.g. HR12A palmpad). Also, if it is the CGFI that's blocking X-10, it may
be bidirectional in effect and may still attenuate PLC signals even when
injected downstream.

I would try temporarily replacing the CGFI outlet with a standard one to
verify that it is the culprit.
