The band(s) used is(are) L 10Jan 14:02:04 Note: File started early due to a NOD SKYscan in sub1. 10Jan 14:49:00 Your new operator is: Tom Briscoe 10Jan 15:50:00 Inspected the VLB instrumentation. No problems found. 10Jan 16:10:00 Note: Total power levels on baseband channels 3-8 are low and/or fluctuating. This is likely due to conflicts between the subarrays regarding setting of the Fluke synthesizer frequencies. At 19:07 the Fluke set in use for subarray 2 was changed from set 2 to set 1. The conflict was cleared up. Please check your data. 10Jan 16:51:00 Inspected the VLB instrumentation. No problems found. 10Jan 17:54:00 Inspected the VLB instrumentation. No problems found. 10Jan 18:58:00 Inspected the VLB instrumentation. No problems found. 10Jan 19:55:00 Inspected the VLB instrumentation. No problems found. 10Jan 20:31:00 Observation was terminated early because of Fluke synthesizer problems.
