Subject:
TWP/MMCR/C2 - MMCR Inoperative due to antenna, TWTA, and Solaris computer failures
DataStreams:twpmmcrmomentsC2.00, twpmmcrmomentsC2.a1, twpmmcrcalC2.a1, twpmmcrcalC2.00
Description:
During the time period covered by this DQR, the MMCR experienced failures of several major 
components, namely the TWTA, antenna, and Solaris computer.  The MMCR may have generated 
some data files during this period during troubleshooting but, for the most part, data 
were not generated.
Suggestions: 
No usable data were generated during the period covered by this DQR.
