Deane,
All the X10 remotes transmit in both X10 IR and RF.
We just added the PUR09 (SH's 4006).
[Link: homeautomationnet.com] of course for less than their hot deal.
You still need an RF transciever PAT01or the IR543 if you are going IR to control X10 . Nothing will control X10 directly. If you think about it, how could a signal get in sync on your power line directly without some sort of intermediate device, would be an pretty neet trick.
