Description: | During my daily review of the MMCR operaton, I noticed that the radar returns were out of
synch with returns appearing all throughout the range gates. I remotely rebooted the
MMCR and it returned to normal operation. |

Description: | A power supply failed in the MMCR's receiver. During the period of this DQR, the radar
would appear to work but the calibration is probably incoorect during good portions of this
time. The power supply was replaced and normal operation resumed at 2115 on 02/11/2005. |

Subject: | SGP/MMCR/C1 - TWTA Faulting |
DataStreams: | sgpmmcrmomC1.b1, sgpmmcrspecmomC1.a0, sgpmmcrmomC1.00
|
Description: | 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. |
