I have the 100 watt version, but when the rig changes over to low
power I can hear a relay click.  If I check the power out with the
Control software of the W2 my output is 11.9 watts.  Some rigs may be
different.  My voltage drops to 11.5 volts from 13.2 with the key down
due to a long power cord from my voltage source to the K3.  I suspect
the output would be higher if the cord were shorter or heavier.

When I am operating on 30m and feel like I need the full 200w there I
set the power on the K3 at around 3 watts.  Driving my Alpha 87A with
that power gets me 200w on 30m.
