Yg FS upgraded to 9.11.4
FS software at Yg has been upgraded to 9.11.4 Detailed notes are here
Hb FS upgraded to 9.11.3
The Field System software at Hb has been upgraded to version 9.11.3. We're still running v102 of the DBBC software. Testing of v104 is required. Here are detailed notes on what was done.
Katherine pointing model update
Following reports of large pointing offsets (~0.05') from crf77, two days of pointing data was collected with acquire (252-254) and was processed with pdplt and update. The new model parameters are

Yg Data Link
The NanoStation/ADSL link went down on Sunday 25th August. The problem is at the Mingenew end, up the mast. A replacement NanoStation has been ordered for if the existing unit is damaged irreparably.
It was fixed on the Wednesday following with a new NanoStation. The guy wires will need replacing because of corrosion.
The problem has repeated itself yesterday (sep10), this time at the wind mill. Some cable ties let go there and the DC supply was interrupted. It was fixed late yesterday afternoon.
