     * CRDS82 - "still getting ve error: ERROR ch -308 ve total power integrator overflow"​ - Bryn, what was this and was it fixed?     * 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?     * 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.

 +       - 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.     * High system temperatures - run systemp12 again to make sure it wasn't just one dodgy reading.
