An X10 controller creates a 121 kHz carrier, superimposed
on the 60 hZ AC line. At the 60 hZ 0 crossing, the system
sends pulses of that carrier frequency, containing an
address and a command. The address tells which remote X10
device to respond, and the command tells it how to respond.

An X10 wireless system consists of an RF transmitter, that
sends a code to an X10 transceiver. The transceiver receives
the RF, decodes it into address and command, and then operates
the same way as the controller. In addition, the transceiver
can act as an X10 remote device, controlling whatever is
connected to it according the command whenever it is addressed.
to send pulses out to the X10 devices.

Actually, it sends three one millisecond pulses over a cycle of the
power, 1/180th a second apart. One for each zero crossing of the three
possible phases. One bit takes two cycles, with the data sent at the
zero crossings and it's complement the next cycle. Total data rate
including overhead is something like 22 bits per second.

I haven't followed this thread closely.

Have you visited the X-1 site? http://www.x10.com/

I use a lot of X-10 and believe it does a good job. The transceiver is
annoying at times, because it seems to become confused when I add another
"appliance module." For a short while, it fails to repeat the on-off commands
it receives from the RF transmitter. However if I just ignore it for about 15
minutes, it starts repeating the commands again as I issue them.

One of the features I like is that I can have all the appliance modules for my
neon set to the same code so they turn on and off together. Same for the
yard's security lights - one address for all.

Their RF wall switch is a neat idea too. You can place it on a wall wherever
you want as long as it is in range of the Tranceiver module. Use it in place
of one of the small portable commanders such as the keyfob unit.

The Transceiver (TM751)is now $12.99, the Universal Module (UM506) with
isolated output contacts is $18.99, and the keychain remote (KR19A) is rip-off
priced at $19.99. Because it's over $40 you will get free shipping.

These people have a sale-per-day.
