Anomalies:

DOY 359-360 (12/25-26/05)  G05-0156  No VC2 (Playback) Data
VC2 playback data stopped flowing from fanout about 40 minutes after BOT on
DOY 359 and continued through DOY 360.  FOT downloaded the CDR files for DOY
359 and 360 from DSN which did have all the data.  CDManager informed FOT
that while fixing a problem on DOY359, the fanout went to default settings.
The settings were corrected on DOY 360.
IMPACTS: No VC2 playback data for 2 days.  Would have had 15 hours of
playback data loss if FOT had not downloaded the CDR to update the automated
SSR operations.  All data was recovered.

DOY 361 (12/27/05)  G05-0157  No Lock on CDH B
DSS-16 did not obtain lock on Spacecraft Receiver B at BOT.  The command mod
index was incorrectly set at 1.76 radians vice 0.86 radians.  DR G106376.
IMPACTS: 1 cmd for CDH B (inactive CDH) did not make it to the spacecraft.

DOY 363 (12/29/05)  G05-0158  Incorrect Command Mod Index
DSS-16 had the command mod index incorrectly set at 0.75 dB vice 1.69 dB.
DR G106380
IMPACTS: 1 cmd for CDH B (inactive CDH) did not make it to the spacecraft.
