| - | * 19:26 UT - delay difference drifted again to 0.435 us, going to try and see if restarting DBBC software helps. halted schedule during 256-1925a, first scan after reset will be 256-1944. (Tiege) | + | * 19:26 UT - delay difference drifted again to 0.435 us, going to try and see if restarting DBBC software helps, seems to be staying at the nominal ~0.257 us post-reset. Halted schedule during 256-1925a, first scan after reset will be 256-1944. (Tiege) |
| + | * 22:59 UT - Have noticed that in the time between the previous two checklists ( time where I was asleep) the delay difference has very slowly drifted from ~0.26 us to 0.285 us, gradual enough that is hasn't yet set off the alarm. Jim will be taking over soon so I will mention it to him. (Tiege) | ||
| + | * 23:25 UT: DBBC was still causing a drift so rebooted the machine. Jim | ||
| + | * 23:37 UT: Restarted with scan 256-2347. OK now. Jim | ||

| * 18:25 UT - Total missed/dodgy scans list: 256-1700b to 256-1733b inclusive were recorded onto USN-0069 using mk5ke (potentially dodgy), scans 256-1742 through to 256-1802 were missed while switching to mk5-2ke, 256-1808 and 256-1809 WERE RECORDED on the new disk (USN-0017), then 256-1814 through to 256-1827b were missed attempting to correct clkoff issue.

| + | * **0720UT to 1030UT** (JS) | ||
| + | * MK5-2KE crashed as well, this was a UPS issure but in the meantime MK5 was fixed | ||
| + | * GPIB fixed, clkoff/maserdelay now working | ||
| + | * Module USN-0017 transferred from mk5-2ke to mk5 bank A, recording will continue on this | ||
