Have restarted / rebooted DBBC, mark5, hobart etc. Warren will look at it in the morning. 0537 - Experiment resumed after dealing with multiple issues. DBBC was in unusable state, apparently due to a fault in the 10 MHz reference cable. Also investigated RF/IF system following up on recentr non-detections.
