  • 29sep05: added 430 carriage house cal values. Looks like there is a bad match in polA starting at the diode. The reflection is 3.75 meters in air, (2.75 m if velocity is .7c).
  • 30sep05: at midnite (start of 30sep05) a 1 second tick was inadvertantly inserted into the station clock. The clock was off by 1 second (The station clock provided a time that was 1 second behind the correct time). The  offset was corrected  about 8:30 am 30sep05. During the morning of 30sep05 the tiedowns were acting strange and the rotatary floor vibrated a bit. I think this was because of the 1 second time difference. The little star computers did not jump with the 1 second tick insertion. The time stamped positions that they received were one second late, so most of the tracking commands sent to them would have be ignored.
  • 03oct05: Early morning, the sband radar run had trouble with the cal program that fires the cal. This program runs on the corp1 computer. Programs were not able to communicate with it. Rebooting the cor crate fixed it. The backplane network for the correlator crate has been subnetted. This problem has occurred in the past. That time a computer using the "other" part of the subnet sent arp packets saying that they also belonged to the "cor backplane" part of the sub net. This caused requests to go to this "other" computer rather than the cor backplane (there is no evidence that this is what actually happenned this time..).
