 +**Hb** TR-00014
 +  * RFI spikes in ch 14, 15 (0-15) (Liza)
 +  * 22:07 UT - Windstowed (vk)
 +  * 22:46 UT - Observations resumed. Missed scans: 300-2210b to 300-2241 corresponding to deficit of 36 Gb 
 +  * 23:19 UT - Windstowed
 +  * 23:31 UT - Obs resumed. Missed scans: 300-2320a, 300-2325b and 300-2327 corresponding to cumulative deficit of 42 Gb
 +  * Hb needed manual intervention to recover from above windstows.
 +  * 301/00:43 UT - Windstowed
 +  * 00:52 UT - Obs resumed. Missed scans: 301-0040, 301-0046 and 301-0050 corresponding to cumulative deficit of 62 Gb.
 +  * Reported cumulative deficit with disk_pos is ~20 Gb, not 62 Gb. This is because mk5 begins to record after command to exit windstow is issued, even though the antenna drives do not activate until fs is restarted.
 +  * 01:24 UT - Windstowd
 +  * 07:12 UT - Returned from windstow. First scan 301-0712a. (DH)

 + HOBART12 (Hb/d): Missed scans:
 +                  from UT 300-2210b to UT 300-2241, 
 +                  at UT 300-2320a, UT 300-2325b and UT 300-2327,
 +                  at UT 301-0040, UT 301-0046 and UT 301-0050, 
 +                  from UT 301-0124 to UT 301-0712
 +                  due to windstow.
 +
 +                  Note that some of the above scans contribute to the 
 +                  statistics as non-detections.
 +
 + KATH12M  (Ke/a): Ok. 
 +
 + YARRA12M (Yg/i): Ok. 
 +
 +Problems: Hobart12 had several windstows, one lasting ~6 hrs. 
 +          The cable cal at NYALES20 was unstable, with 2 breaks.
 +          It was not applied. This has happened several times
 +          recently and is being investigated. 
 +
 +Parameterization comments: None. 
 +
 +Other comments: None.
