Hi James,

        Check out http://www.cix.co.uk/~pplunkett/x10.htm. This may
be of some use.

        Also http://www.national.com/an/AN/AN-146.pdf this is an old
appnote for sending FM through the AC line but it specifies line
signal xformers. I used these with appropriate caps to tune to the
x10 signal frequency.

        The part numbers have changed since the appnote. The parts I
ordered many years ago were TOKO RAN 10A6729 for the Tx xformer, and
RAN 10A6845 for the Rx xformer, they may gave changed since then?

        There's also an x10 module TW523 that provides logic level
x10 RX, TX and zero crossing and a PIC based Weeder Technologies Home
Automation Controller that allows serial/ASCII control of the TW523.

Hope this helps,
Heinz
