Reset time and date and restarted lowl program, data writing to L00620 in drive #0. Cleaned drive #1 and loaded L00621. **MKIV PROBLEM**: Tue Aug 17 16:46:19 GMT 1999 KCC display is streaky (radial streaks). Not sure whether this is a result of new program picked up this morning or the "usual" streaks we see when the KCC flakes out. Stopping Patrol gracefully and parking barrel with End Day then resetting the KCC. Tue Aug 17 17:00:06 GMT 1999 MKIV Start Patrol **PICS PROBLEM**: Tue Aug 17 17:01:23 GMT 1999 YCC monitor is off, stopping PICS and CHIP and resetting YCC after calibration and hourly transfers pau.

There are "bright" outer wedges at the east and west quadrants. This is possibly a result of the program changes made by David overnight??? **MKIV PROBLEM**: Tue Aug 17 17:45:23 GMT 1999 Bright wedges might have actually been bad sky??? They were gone in last few scans at 0.5 gain. MKIII was dark in that region until last few scans too. Tue Aug 17 17:46:56 GMT 1999 MKIV Start Correct Tue Aug 17 17:46:57 GMT 1999 Running a MKIV correct.

MKIV COMMENT: Tue Aug 17 18:32:12 GMT 1999 Re-doing calibration. First attempt was short for some reason according to Alice. **MKIV PROBLEM**: Tue Aug 17 18:56:28 GMT 1999 Changes made by David did not get rid of noise. Stopping MKIII/IV and opening up MKIV to remove video cable from back of camera to see if that is somehow injecting noise into the system. **MKIV PROBLEM**: Tue Aug 17 19:01:36 GMT 1999 OK, video cable is unplugged, BNC is taped up and secured so it won't touch any part of the camera during this test.

Noise still present. Tue Aug 17 21:16:41 GMT 1999 MKIV Start Patrol **MKIV PROBLEM**: Tue Aug 17 21:16:48 GMT 1999 Checked for discrepancies between jumper settings on new transformation board and the old one. Emailed list of discrepancies to David for analysis--there were discrepancies and these were purposely made when we changed transformation boards. **MKIV PROBLEM**: Tue Aug 17 21:36:36 GMT 1999 Swapped jumpers from 320 to 322 on the transformation board. **MKIV PROBLEM**: Tue Aug 17 21:44:11 GMT 1999 Display disappeared with that jumper change. **MKIV PROBLEM**: Tue Aug 17 21:45:37 GMT 1999 Restoring jumpers on 320 and 322. **MKIV PROBLEM**: Tue Aug 17 21:46:44 GMT 1999 swapping switch settings on U2 and U3 to old settings. **MKIV PROBLEM**: Tue Aug 17 21:49:05 GMT 1999 OK, done. **MKIV PROBLEM**: Tue Aug 17 21:54:40 GMT 1999 I do not see any change in the display noise with that swap. Resetting U2 and U3 switch settings back to where they were and configuring straps on 408, 409, and 410 to the old configuration. **MKIV PROBLEM**: Tue Aug 17 21:58:29 GMT 1999 OK, done. Display currently showing circular streaks. Let's see what happens when the scan resets.

I will restore straps one at a time. **MKIV PROBLEM**: Tue Aug 17 22:05:04 GMT 1999 Removed 410 briefly and coronal display returned. Put 409 back and display remained the same. strapped 410 again briefly (with 409 strapped) and streaks reappeared. Strapped 408 alone and image appeared. Strapped 410 again, with 408 and streaks recurred. Removed strap from 410 and strapped 409, the original configuration for the new board. display is back. None of those swaps appeared to improve on the S/N in the displayed image.
