[Dx4win] CW Using DX4WIN

[Franki - ON5ZO]

OK, this is Guy's ON4AOI way of doing it:

He makes a galvanic separation between PC and TRX by means of an
optocoupler.
This is a smart idea that might help to cure some problems with
RFI and noise.
The schematics are also easier to understand than my text
description, hi!

I personally have NEVER had any problems with the simple circuit,
nor have most of the people I know. But: it definately does not
hurt to make a galvanic separation. Thanks for the hint Guy!
