48hz line has been noisy!  But then all of a sudden DARM took a dramatic drop in the bucket area of spectrum.  Then DARM had a broadband drop in DARM all the way up to several kHz (but also look like many more high-freq lines & now a minute or two later seeing low freq glitches.

NOTE:  Observed range which went up to 170mpc briefly!!

And now we just had a lockloss.  

Will look into reverting back to 35W.

Will post some screenshots in a bit....after working on locking.
