Current Issues

    * Problems with drive hydraulics on 26m, cancelled today's experiment (RD1603).
       - New something being bought by Eric

    * New PCFS at Hobart is working great (thanks Jamie). Has anyone had any problems?

    * Maser maintenance at both Katherine and Yarragadee currently, hence Brett is not at the Observatory. Warren is at Mt Pleasant Tuesdays to Thursdays and occasionally Mondays.

    * CRDS82 - "still getting ve error: ERROR ch -308 ve total power integrator overflow" - Bryn, what was this and was it fixed?
      - High tsys values due to RFI

    * R4734 - Yarragadee: consistent offset between mark 5 and other computers of 0.1 - 0.4 visible in fmset with no sync error, could not be fixed. Caused by power failure affecting GPS receiver (new UPS installed) - had to change to Hobart's. Fixed itself 4+ hours later. Is there any way to fix this other than hope?
     - Probably ntp problem

    * R1735 - A couple of instances where recorder started ~ 7-10 seconds before onsource at both Katherine and Yarragadee.
       - possibly due to tag along experiment

    * High system temperatures - run systemp12 again to make sure it wasn't just one dodgy reading. Monitor and make note of how many scans were affected by consistent high tsys values.
      - elevation and weather affects tsys values
      - would be cool if monica can track changes

    * Anything else to note?
    * VSNs all reported as the same for 4 telescopes in end message (Jesse check experiment) - keep an eye on this
