[Elecraft] KPA3 for the QRP enthusiast

Thanks to those who submitted current measurements for
the K3 with and without the KPA3.  I found the
information very interesting and I am not surprised
that the measurements vary somewhat depending on the
individual unit.  The measurements that I saw
indicated that the additional current drain was
between 200 and 600 ma. and applies only when the rig
was in transmit.  Even the most aggressive contester
will not be able to stay in the transmit mode 40% of
the time.  To this extent, the difference in drain
would only be important to those who need to carry
their entire station in one trip.  If you need to run
on a 6 to 10 amp hour battery, maybe it is important
to you

It appears to me that the most important consideration
is cost.  I will keep my KPA3 on order, but since I am
a QRO operator most of the time, that was never in
question.
