I tweaked the beam alignment into the PMC; the ISS was OFF for this.  I was able to get the reflected power down to ~16.5 W from ~17.5 W.  I think we are being limited by mode matching here, as the mode out of the HPO has likely changed (especially since the diode box swap).  With the ISS back ON, the PMC is transmitting 57.2 W and reflecting 16.5 W.  This completes LHO WP 7108.
