| - | * **ho:** Receiver heating up again - seems to be happening regularly? | + | * **ke:** ES Oven V Katherine maser fluctuate from blue colour (0.9) to red colour (25.8). Brett came to auscope room and had a look at this problem. We sent an email the history file of maser KE to Anton and Jamie (mas) |
| - | * Ask whoever is out at telescope to cool it down at the end of the day | + | |
| - | * Fix is replacing cold head, but it is a major job - not happening anytime soon | + | |

| - | * **ke:** Difference between Mk5/Fs of 1 second. Happened twice - to sync or not to sync? | + | |
| - | * If detected after start of experiment, leave it (fairly easy to fix by correlator) | + | |
| - | * This is usually caused when ntp time not correct when DIMino started | + | |
| - | * Sometimes out by ~0.4 of a second, stable, but can't fix with fmset (also due to ntp time). A reboot will usually fix it | + | |
