Estop was tripped and required Mick to go manually reboot drives.
1700UT Experiment started okay (Lucas).
17:30 Maserdelay was reading way off (around 5-7us instead of ~2) so I reconfigured and synced the dbbc and delays have settled to nominal values with an offset of -0.3 (Lucas).
18:20 DBBC delay shifted dramatically. Delay difference has been slowly drifting also (Lucas).
Power cycling both dbbc and mk5, reconfiguring, restarting dimino and resyncing.
Delays and offsets back to normal. Probably will drift again. Missed scans 1824a to 1836 (Lucas).
Offsets gradually shifted again then at 20:40 ish the dbbc delay began shifting. At this point I again reset the dbbc but in the time since I have written this the offsets have shifted again. Something seems seriously wrong (Lucas).
21:32:20 Ran dbbc=pps_sync to adjust dbbc delay as offsets began to plateau out (Lucas).
22:03 halted schedule for another dbbc restart , missed scans 002-2203b to 002-2217a (warren)
22:30 resumed schedule with 002-2222 (w)
23:02 halted schedule for dbbc 2 hr cool-down, missed scans 002-2304b to 003-0053a (w)
00:55 resumed at scan 003-0055 (w)
01:00 dbbc delay still drifting! (w)
03:03 abandoning experiment dbbc faulty (w)
03:55 yet another attempt to fix dbbc, to no avail, resumed at 003-0352 (w)
05:32 recording anyway in case some sense can be made of data (w)
05:38 fmset to set delay back to 0.29 us
