                              Introduction and Motivation
The project will have a number of students working on it. The students we currently
have on our team are either pure physics majors or are combining physics with
electrical or mechanical engineering. We would like to use the radio telescope to give
undergraduate physics students the opportunity to do some radio astronomy before
they attend the annual Astrotrip, to get the maximum benefit from the trip. Several of
us on the project have visited most of the radio telescopes in New South Wales on our
Astrotrip but have done no radio astronomy. Our core project members are keen
physics students and have skills in electronics, computer hardware and software and
mechanical engineering.

                                 Outline of the project.
      Safety briefing and review of procedures.
      Rooftop. Clean and service dish – grease (or replace) bearings and actuators
       (if replacement is needed we would need to discuss the preferred method of
       doing so). Check limit switches/encoders. We would like to keep the servo
       control of the dish.
      Receiver room. Take an inventory of equipment. Test computer and servo
       amplifier and other equipment disconnected from the dish. Check roof-room
       cables for faults. We will donate a more powerful computer to the receiver
      If actuators and computer are working otherwise manually point dish onto a
       geostationary satellite with the Ku band feed installed. Tune a tv receiver to
       the signal. Repeat with C band.
      Do a drift scan of the sun with the 3 different feeds. Repeat with moon.
      Investigate sources of RFI at 21, 7.5, 2.5cm
      21cm sky survey, perhaps limited to interesting features.

   Once we have accomplished the above we have considered the following.
    Investigating the effects of cooling a LNC. To do this we would consider
      building a container in which solid carbon dioxide pellets (dry ice) could be
      contained close to the LNC.
    Build and install a 2.4GHz feed for detecting wireless networks.
    Detection of moon bounce signals from the moon.
    Design a new computer dish tracking program or trial a off the shelf software

                            Suggested safety modifications
      Installation of an audio/visual indicator to warn that dish is in operation.
      Wind meter to monitor wind speed from receiver room.

                                 Project funding
When equipment is needed, we would seek to make an arrangement with the School,
Physoc, Student Guild and Union and external organisations such as the ATNF.
