[ARC5] TCS Transmitter Tip

[Michael Hanz]

I took Scott's meaning as suggesting a way to speed up the relay as 
_compared_ with using a solid state diode.  At least that's the way I 
understood it, given Scott's extensive experience.  Sometimes it takes 
some parsing of the English language when we write.  For example, I 
simply answered Wayne's specific question, not having the time at lunch 
today to write a tome on all the possible ways to suppress a voltage 
spike.  I had a feeling there would be others chiming in with a bunch 
more, and sure enough - opportunity to share!

        73,
