Safety Relay and feed re-seal
I am taking the cherry picker to the antenna now, Fri 19th March 0245 UT. I shall be performing the Safety Relay - Manual to Automatic Restart - modification so that we do not need to go to the antenna to restart it after a power fault. I shall also use the cherry picker and go to the feed and replace the temporary duct tape preventing water ingress, pending the replacement feed coming. The antenna will be free for use after 4.00 pm, or call me if you need it earlier. Brett Reid 19/3 2.50pm
12m pointing solution v1
A new pointing solution (based on 13 observations only) has been loaded into the controller. See Antenna pointing solutions.
Solutions have been entered into the controller but further observations to verify/improve are required.
Maser to Yarragadee
The NASA Cesium clock used for the SLR at Yarragadee has died, so we've offered to send a maser (which will become the standard for the whole site).
We will send the maser around April 15 and Brett will travel to Yarragadee to install it.
Pointing
More pointing observations were completed yesterday (March 17) although the cloudy weather made observations difficult for weaker sources. I am attempting to obtain a new solution but more observations may be required.
Anemometer
From Brett Reid: “We have tested that a closure of the contacts coming from the new anemometer produces a wind stow of the antenna. This was following Brenton connecting the wires according to Mark's email and me restoring the connection after removing the governor's press button.”
We tested on March 9th during high winds. Some gusts came that stowed the 26m and the 12m stowed at about the same time. It works.
On Wed Mar 17 Tim called out and showed us the 2 pieces of anemometer software currently installed on the PC used to control the antenna. That all works too.
He updated the software to the latest version, same as Yarragadee and Katherine.
The latest version of software needs testing again on a day of high wind by tipping the dish to 80 degrees elevation, leaving the drives on and seeing if the dish stows OK when the strong wind comes. We should also ask Tim what the threshold is set to.
Tim found a potential issue with the backup lithium battery and is testing the Katherine instrument at home. I will take the Yarragadee instrument with me on Monday 22nd March and install it and test it that week. Brett Reid 18/3/2010
Following the power failure overnight I discovered the AneMonitor Hobart display freezes with red ¨Not Connected¨ warning message displayed, even after power is restored. The display works normally again after doing ¨options¨ then ¨connect to device¨ and accepting the defaults. Brett Reid 19/3/2010
