1. When I came in, Y VCO "tune ofst" was railing at -5V ("tune mon" 8.3V or so). As such, the VCO frequency was higher than 80 MHz (set frequency is 78.92MHz) and the beat note somewhat above 40MHz. Manually resetting it, "frequency servo" brought it back. This is will PLL only, no PDH. I thought that the "tune mon" is the readback of the VCO "tune" input on the front panel, but it was 8.3V even when I terminated the BNC. Apparently I forgot these things.

2. At the end station, I reseated the two slow controls cables for PDH CM board at Beckhoff chassis end, and locked the arm green, no change in glitches.

3. Connected the CM tester to refl CM to lock the arm but failed. I think the tester setting was good but maybe some automation was doing something funny though I disabled the state machine in the ALS overview. Refl CM was put back on slow controls cables.

4. Switched the PFD channel, locked the arm,  glitches persist. Switched it back.

5. Time's up for the day.
