Anyone else had any problem with optos not keying the VOX on their rigs,
but keying the CW just fine?  That's what happens on my TS-930 --
fortunately I also use TR's PTT function to avoid hot-switching my amp, and
that works fine.  

I would like to be able to use DX4WIN's CW keyboard, though, which does not
have the PTT function.  I'm guessing that this problem is like some of the
early solid-state keying circuits, that wouldn't key some rigs because they
didn't pull the key line all the way to zero.  I'm purely a cookbook
technician, and would appreciate any ready-made wisdom as to how to fix
such a problem.
