[aprssig] KPC3+

It could be a grounding issue.
disconnect the KPC3+ from the PC
then check to see if there is any
voltage between the grounds from
the PC and the KPC3+.  There are
two grounds - signal ground and
chassis ground that is usually
transferred through the shield
on the cable.  If there is a voltage,
turn the walwart the other direction
at the wall outlet and try again.

Well guys, I have checked the jumper settings and alll appear to be
correct. Unplugged walwart and no power. This computer and cable does
work on a KPC3 here at the qth. Also on a KPC3+ on the hill 30 miles
away.  Any other ideas
