Attended: Jesse, Prad, Lim, Jay, Simin, Lucas, Earl, Tiege, Atifur, Jamie, Katie

Apologies:

Absent:

General Issues

  • The X-band values of tsys show up as '$$$$$$' at Katherine due to issue with cal.
    • Restarting dbbc fixed this, appears to be benign. If it happens again may be an actual problem. Note anything like this!
  • Ross scheduled when in Sydney and Melbourne, Friday at 5pm on 8th and 30th of November. Swap and/or take?

Handover Issues

Katherine

  • R1865 - Large delay difference. clkoff command results in significantly different value. The Tac32 clock was found to be stuck and restarted.
    • Antenna was also stuck, maybe a power failure?? Maser at Katherine is reporting problems, problems with ke maser has come back, oscillating between low and high values. Need to go back and fix again most likely. May be causing problems with the other systems.
  • R1866 - Katherine delay offset drift at around 5pm ( similar to the old issue), restarting the DBBC software → re-syncing → fmset seemed to fix it. Remained stable after this.
    • Same time as usual, but fixed with a single re-sync.
  • R4866 - Katherine developed a large delay offset (~8 us). Simin you said the fix Tiege suggested didnt work? What fixed this?

Yarragadee

  • R4864 - maseryg vnc not connecting.
