XTB-II 2-Phase Version

["Jeff Volp" <JeffVolp@xxxxxxx>]

Hello All,



Several people have requested a passive coupler be included with the XTB.
When I first started the XTB project, I had considered having two output
coupling networks so the XTB would directly drive each phase.  I abandoned
that approach because I thought it would have limited acceptance.



Now that people see what the XTB can do, I am considering a XTB-II, to drive
both phases directly.  It would be packaged in a larger module with a
terminal strip to accept any type of 240V grounded input cable.  With more
room available, a microcontroller could be added to gate received and
transmitted signals, and perhaps generate and decode the X10 signal
directly.  The same approach could be used for a XTB-III three-phase unit
with gated drive to each phase at their zero crossings.  A similarly
packaged 240V single-phase European version is also a possibility.



I still have doubts about the marketability of units like this, and would
like to get some feedback as to whether a project like this is worth the
investment.



Thanks to all who have accepted the current version of the XTB.
