After all the hub bub of a Maintenance Day, the site is somewhat quieter (no one here and the winds are finally mostly under 20mph).  

Made a couple of lock attempts starting just before my shift.  First two locks did not last long:

• Lock#1 ended due to PI Mode 27 (it had a setting of -70deg phase & +7000 gain).  Range was an ugly 60Mpc
• Lock#2 broke lock after a few min at NLN.  No obvious reason.  Range was a much better 70+Mpc
• Lock#3 (also at a decent 70+Mpc) ended due to PI Mode27 (same settings as above.  Tried various changes to no avail and it broke lock within 3min while also ringing up neighboring modes).  Gave Terra a call for help!  She had me check the Mode27 freq (it is 14039.5Hz.  BP Filter is 18038.5 with PLL set frequency of 238.5.....Terra thought this should be wide enough for that mode.)  

As noted earlier we ran the gamut of rung up modes (roll, some bounce, violin & now noticing PI modes).  So I am going to stay at DC Readout for a while (Terra suggested ~15min) & then we'll go from there.
