[Elecraft] Transverter issue with K2

[Phillip Shepard]

I have a K2 (without a K60XV) and an XV50.  I am having some issues with
power output.  After I turn on the K2/XV50 pair (or often after I come out
of menu mode), the power output LEDs on the XV50 don't light with tune
activated (or the keyer action).  The K2 power control is fully CCW.  If I
turn up (CW) the K2 power control, the 20W power out LED lights upon tune.
Turning the K2 power control back to minimum leaves the XV50 power out at
15W or 20W, and the action seems normal then; except that I need to be able
to turn the power out down to 10W so that I don't over drive an external TE
Systems 170W brick amplifier.  As far as I know, I followed the jumper
settings in the XV50 assembly manual for the "Elecraft K2 with no K60XV"
section.  The PA is turned off.  What do I need to do to get smooth power
control that is settable to 10W out of the XV50?  Thanks.
