[TRLog] Switch box

[Tree N6TR]

I found a design improvement to make to my switch box (at W5WMU).

I was having problems with the PTT and CW signals being driven
sufficiently for the transistors to turn on.  When I found the
problem on two computers, I decided I needed to fix the box.

I found some 2.2 or 2.7K resistors and pulled all of the signals
coming from the computer up to 5 volts with them.  This totally
fixed the problem and ran for 1485 QSOs during the SS with no
problems.

Guess I was just lucky at home.
