[Elecraft] KPA100 DC connector WARNING ALERT

[Stan Rife]

	I think it is all in how you look at it. RED is always on the right,
as viewed from the top & back of the red and black shells. RED is also on
the right coming out of the K2, if you look at it from the top & back of the
connector shells, or as viewed from top & front of the radio. It should also
be this way on every connection you make. I think the confusion stems from
the fact that you have to flip one set of connectors (red/black) 180 degrees
to have it plug in to another set. Did I make any sense here? Hi Hi.

Steve and all,

I don't usually disagree with you Steve, but I looked at my APP cables that
DO work FB with my KPA100 and they look just like the pictures in all your
references.

Yes, if one looks at the the KPA100 input, it may look like it is reversed,
but it DOES mate properly with the cables that are configured just like the
'standard'.  As an added note -- my Rigrunner connectors look like they are
reversed too - but they have to be that way to mate with the cables pictured
in the references.  The pictures show the cable and not the mating connector
in the housing.

A word to the wise is still in order - before connecting ANY equipment to
someone else's cables, be certain the polarity is correct!!!  Especially on
Field Day, but on every other day as well.
