CHIP Startup--Initializing new tape Wed Aug 14 16:42:46 GMT 1996 dPMon Start Patrol Wed Aug 14 16:43:08 GMT 1996 CHIP CHIP Start Patrol MKIII COMMENT: Wed Aug 14 16:47:19 GMT 1996 Before starting up, I checked seating of analog corrector cards and two of them were indeed loosely seated as DAK described. I reseated them and there was a bit of extra effort required to seat them firmly, but there was a difference in seating. At startup, oscilloscope sync'd up as soon as the microprocessor kicked in.

Anyhow, rings are common to both channels, I am told, so problem is not occurring anywhere channels are separate.

I noticed this while entering calibration values into the cal notebook. Peaks were at 148-150 degrees and not around 180 where they normally are. Peaks are OK today. MKIII COMMENT: Wed Aug 14 18:45:27 GMT 1996 Phasing was off for DOY 225. MKIII COMMENT: Wed Aug 14 18:53:03 GMT 1996 Saved NMAP image for DOY 225 got hosed somehow, says it is chan 3, there is no coronal contours but Darryl has an Activity (SBH) listing for image. It may have gotten hosed in the FLIP after activity was done. Because of this situation it isn't clear whether the phasing was wrong at any time other than the 15TLT cal scan. MKIII COMMENT: Wed Aug 14 18:57:38 GMT 1996 Image stored in HISTORY is correct channel so something happened after the image was taken.

MKIII COMMENT: Wed Aug 14 19:29:22 GMT 1996 PGA monitor scope has a strange noise going thru it that I hadn't noticed before. Seems localized to the scope.
