IMC was relocking but not holding.  Talked to Sheila, and she showed us how to toggle the Noise Eater - picture attached showing the switch.

IMC relocked, PSL ISS came back bad, with the loop being toggled on/off due to power, so Jason adjusted the REFSIGNAL to bring the Reflected power back to about 10% where ISS is stable.
