Status
• Initial test observations using 64MHz zoom modes are currently underway.
• 1MHz zoom mode will be revisited to rectify known baseline problems.
• Anticipated that 4MHz and 16MHz modes will follow in that order.
• Phil Edwards will describe progress in greater detail.
Compact Array Broadband Backend
Challenges
The imminent retirement of Warwick Wilson means we are canvassing of options for continuing his CABB work.

1 – 3GHz Receiver Progress
• OMT replacement complete. (Aug 2010)
• Dewar and RF signal path upgrade completed on 4 antennas. (Aug 2010)
• CA05 will be the next antenna to be outfitted in October 2010.
• CA05 installation will include prototype receiver electronics.
• ATCA outfitting scheduled to be completed in December 2010.
• Spare receiver and remaining work to be completed in early 2011.

1 – 3GHz Receiver Performance
20/13 and 6/3 cm Upgrade Project
Jamie Stevens has completed beam pattern measurements. Available at:
http://jamiestevens-atca.wikidot.com/beamshape-measurements-of-new-l-s-receivers-on-2010-08-26
Primary beams are symmetrical within 6%, independent of frequency (1.1 - 3.1 GHz).

4 – 12GHz Receiver Upgrade
• Australian Astronomy Limited (AAL) funding secured for upgrade.
• Funding commences in July 2011.
• Scheduled for completion in June 2013.
• Prototype 4 – 12GHz LNA development is currently underway. Initial prototype LNA under test in early 2011.
• Prototype receiver under test in laboratory mid 2011.

Parkes Drive Control
• Critical Design Review scheduled for November 2010.
• New MCP scheduled for installation during major maintenance
shutdown in March 2011.
• Full commissioning scheduled for mid 2011.
Parkes Development Projects
CSIRO Astronomy and Space Science - Technologies for Radio Astronomy
Parkes Receiver Rationalisation
• H-OH feed designed and manufactured under contract by BAE Australia. (July 2010)
• H-OH feed tested on ICT Centre range. (Sep 2010)
• H-OH feed commissioning scheduled for March 2011.
• Remaining elements of project:
• S/X Dual banding (MARS Rx)
• C-Band receiver replacement
On hold due to availability of manpower and budget.

Water Vapour Radiometer
• 6 WVR systems delivered.
• Spare system returned to Astrowave for modification (filter replacement).
• 5 systems installed on the ATCA.
• Sample calibrated data collected with CA03 and CA04.
• Preliminary measurements indicate data tracks water vapour phase.
• Remaining systems to installed and calibrated during late 2010.
• Software development and integration into MIRIAD required. (March 2011)

Engineering Development – The Future
What is the future of the CASS engineering development program?
Engineering development day (including CDSCC) held during September 2010.
A range of ideas for the future projects were canvassed.
Ongoing discussions with astronomers regarding possible future projects.
Thank you
