NB Ceduna appears to have variable gain throughout this experiment. This problems appears to be in the receiver itself but was not discovered until toward the end of the LBA session. The problem appears as a sudden drop in the apparent Tsys and affects both channels.
Using DBBC & Mark5C.
No fringes found in RtFC testing of 20:53:43 - searched for integer clock offsets of \pm 4 seconds.
Bitmasking/frequency selection confirmed with tones.
