SGP/WACR/C1 - Radar not in service.

No data collected during this period. Radar was returned to manufacturer for a 
modification which will enable calibration using a pole-mounted corner reflector.

SGP/MMCR/C1 - TWTA Faulting

The MMCR transmitter (TWTA) has been having a low helix current fault.  This results in 
the transmitter shutting down.  However, the radar continues to collect data.  The MMCR 
restarts the TWTA at 0000 each day, hence the 2359 end times for many of these intervals.
