- | * Yarragadee: consistent offset between mark 5 and other computers of 0.1 - 0.4 visible in fmset, could not be fixed. Caused by power failure affecting GPS receiver - had to change to Hobart's. Fixed itself 4+ hours later. | + | 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 |
