After waiting for EQ to die down, tried locking.  PRMI was dead (but off in yaw, so tweaked BS/PRM).  Eventually had some action and locked/optimized PRMI by hand. 

Then continued with locking.  DRMI locked fine and went through most steps fine, except....

Lockloss at:  ENGAGE SOFT LOOPS

Here it looks like we might have been having ASC driving off PRC/SRC (see attached ndscopes).  So maybe I'll need to scripts Jeff K posted about last time I was on shift (alog here) and there were ASC issues last week.  But looking at this lockloss, I'm seeing all kinds of signals getting big (CHARD, CSOFT, DSOFT, etc.) ...so not sure who I would try!  :-/

NOTE:  Did not do an Initial Alignment.  That is another idea to try.
