AuScope (Hobart, Katherine and Yarragadee)
Prototype testing on Callisto feed/receiver system at Hobart due for completion in mid August. The system is performing well but some issues with the 12m optics need addressing: subreflector optimization has helped but more work is required.
Fringe checks are planned with Hobart 26m, Kashima and maybe Ishioka and Kokee if there’s time.
Timeline is for delivery of production systems in January, with installation at all sites by June 2017. Possibility of observing below 3 GHz is questionable.
AuScope Operations funding OK until 1 July 2017 (140 days of observing). Work planned over next 11 months:
- Elevation jackscrew at Yg to be replaced
- Maintenance on Hb maser (will not interrupt operations)
- New azimuth cable wrap mechanisms to be installed at all sites before/during broadband upgrade. Same mechanism as Kokee

Initial testing of Stirling Cycle broadband system has been completed at Hobart. Upgrade of all three sites to broadband planned to be completed by mid 2017 (was hoped to be by the end of 2016).
The prototype is now back in Hobart and will be installed on the 12m in about a week.
