charset="US-Ascii" Content-Length: 2200 Status: RO Hello, Dick, Below are some more explanations. DOY 050 DSS 65 I'm not sure about the low signal yet. Everything was set up correctly. The four which were lost -- the DSP seems to have fallen out of the link. This seems to happen at SPC 60 occassionally, but we have been here in the past. I will notify Sal. 1466e and 1467e suffered from the SPAR initialization failure problem, but the real problem was that the DSP no longer thought that it was in a link. 1467i and 1468i 050/10:12:00 and 12:10:00, respectively Suffer from no signal according to your health report. Scripts ran correctly; attenuation was fine; predicts seem fine; spacecraft should have been one-way. I have to look further. 1469e and 1469i DSS45 DSS45 antenna was going red at the time. The station reported large amplitude variations. We switched the DSP to DSS34. 1471i 050/18:08:00 Another SPAR initialization failure. This will be corrected automatically in the next version of remote ops. 1472e 050/18:57:00 This appears in the log, but I can't find a script. This may have been my fault. 1481i 051/13:46:00 DSS45 You reported this as the wrong filter. Actually there was too much attenuation. Would that explain what you saw? We set up for the wrong DSP at SPC 40. The attenuation settings are very different. 1486e 051/22:26:00 DSS45 You said that there were saturated A/Ds. Where the measurements previous to this one getting close to the edge? The attenuators were set correctly and the same for the entire pass. 1486i 051/23:35:00 DSS45 This was not a gap. It was scripted for DSS 45. I suspect another SPAR initialization problem, but I have to check. 052/09:21:00, 10:12:00, 11:19:00, DSN gap? Yes between 65 and 15 053/16:45:00 "Unknown event" about 2 minutes after ingress. Nothing odd in SOE for this time. This is still open, but it doesn't sound like it should be at the top of the stack. I think that this gets me up-to-date except for the ongoing mysteries. Tonight there will still be Y2k testing at SPC 10, so 1552i through 1554e will be lost. Otherwise, we will be collecting data as usual until I hear that they are going to try NADIR again. -Trish
