Ho : Power outage (22:08-22:44).
Needed to reconfigure dbbc. Data probably bad (22:44-23:58).
Wind stow. Antenna did not recover (01:14-10:45) (16:42-17:23).
Kb : Observed with warm receiver.
Mc : BBC09 (SR1U) out of bandwidth.
Mh : No log (waiting for upload access).
Sm : Some scans missed due to cable wrap in north.
It seems their cable wrap is not well defined.
