Mid-SHIFT SUMMARY: Well, 4 hours ago everything was looking rather ok. Then RF45 glitching started to pound on the range. Jeff K came in and, with the guidance of Rick S., we went out of Observing and turned off P-Cal X to “listen” for a few minutes. Then we changed the frequency of the lines, to no avail. We then changed the EOM RF45 offset around a bit and then set it back to nominal. For a short while, the noise settled away and we got our range back. ≈ 15 minutes ago, the noise has returned and our range has gone wacky again. More news at 4:00PM PST….
