NOTES/ISSUES/PROBLEMS
---------------------
(1) Problems once again with data quality on the downlink.  [It may
    be worth noting that this is the same station (DSS-27) that was
    problematic yesterday during shift M186.]  Switched at approx. 
    22:15 to channel B.  Quality appears to be better, SSR playback
    begun at 22:26.

(2) Noted a couple of single updates of the FID/Star display in splat
    where either 2 or all three of the FIDs shifted in position at 
    approximately 22:35 (VCDU ~7461200).  This occurred more or less 
    simultaneously with Flight Ops noting some telemetry dropout, probably
    the cause of the apparent jumps.  SSR playback stopped at 22:39.

(3) Goldstone noted some RFI on the downlink frequency, which probably
    caused the problems of Note 2 but settled out at ~22:40-45, so OC 
    restarted SSR playback at 22:57.
