Tue Dec 1 17:06:23 GMT 1998 CHIP Startup--Initializing new tape Tue Dec 1 17:11:12 GMT 1998 CHIP CHIP Start Patrol Tue Dec 1 17:11:27 GMT 1998 PICS Start Patrol Tue Dec 1 17:11:58 GMT 1998 MKIII Start Patrol **LOW-L PROBLEM**: Tue Dec 1 17:23:12 GMT 1998 It is cold and I had a hard time getting out of bed this morning, apparently LOWL is having the same problem. It has not woke up yet. Unloading L00559 from drive 1, cleaning both drives, loading L00560 into drive 1 and restarting LOWL. Data should write to L00560 in drive 0. **MKIV PROBLEM**: Tue Dec 1 17:28:41 GMT 1998 MKIV scan looks very streaky (radial streaks). **LOW-L PROBLEM**: Tue Dec 1 17:29:31 GMT 1998 Time and date are 77/77/77 and 77:77:77. LOWL did not wake up upon reset. Powering down and up. **LOW-L PROBLEM**: Tue Dec 1 17:33:46 GMT 1998 Looks llike there is a problem with the CTS-10 board or antenna connection.

Stopping MKIII/IV. Tue Dec 1 18:04:03 GMT 1998 CHIP Water **MKIII PROBLEM**: Tue Dec 1 18:04:47 GMT 1998 Listened to barrel as requested by Alice. At this time, it sounds normal and the drive motor is running smoothely with no detectable vibration (jerkyness). Half-wave plate drive sounds OK.

MKIV is very streaky on KCC display. Monitor scope waveform looks OK. WEATHER COMMENT: Tue Dec 1 20:32:10 GMT 1998 Clear hole. **LOW-L PROBLEM**: Tue Dec 1 20:33:37 GMT 1998 LOWL is running, time and date is OK now. Unsure what happened and when. Data is writing to L00560 in drive 0. LOW-L COMMENT: Tue Dec 1 20:35:23 GMT 1998 Some of the funny numbers are residually still up on the display beyond the correct date and time. Only a cosmetic problem.

Still getting radial streaks. David will take a look at the data and leave us email on a solution, if any, or a means to check the synchronization with the 1/2-wave plate using a PC monitor hooked up to the MKIV signal.
