Adjust the mirror mount before the rotation stage and the one at the base of the IO periscope to
partially bring the beam back to the input modecleaner.  One can certainly see flashes as MC2
swings.  The knobs were moved less than 1/16 of a turn in both axes.

    I limited the power to the input modecleaner to 5 W by using the half waveplate and polariser
combination at the output of the pre-modecleaner.  The output of the photodetector on the table that
monitors the power going into HAM1 did not change appreciably from ~60 mV.

    Since the new EOM is not resonant at 24.1 MHz and because of some changes to the RF signals, the
phase and sign of the error for the input modecleaner may need some adjustment.
