Joe
Thanks for the reply. In the spirit of trying to make useful suggestions
rather than just complaining, let me suggest that once 1.9 is released to the
public, that some additional demonstrations of the new mode be conducted so
that the public could get some practice with it before a real DXPedition starts
using it. Perhaps you have that in mind. It will take a big public
announcement, and a lot of them, to get the message across.

Dave --
All understood. Rest assured, we have already spent plenty of time
thinking about -- and testing -- the sort of complications you describe.
No doubt we will still have some surprises. Some will be ones we have
foreseen, others probably not. That's precisely why we are doing more
testing!
