Tohban notes for Wedesday Feb 28:
The Ant 14 receiver is out of position, so use "No 27m" checkbox until further
notice.
Ant 4 FE Temp is out of range--no solution yet.
Ant 5 has low VPOL power probably due to DCM issue
Ant 7 has no VPOL power probably due to a failed optical link.
Ant 10 has no VPOL power probably due to a failed optical link.
Ant 10 FE Temp reporting bad temperature due to failed sensor.
Ant 14 RX select has an Amp fault. Poor calibrations until the problem
can be identified and fixed.
Report problems here:
Very Late start due to Helios failure. Ran disk checks and memory checks.
Memory tests failed.
Ant 2 is "stuck" at startup. Two power-cycles of the antenna were
required. Tracking at 22:36 UT
Phase Tracking did not start. Ran $scan-start
