LA is writing Mark V disc pack NRAO-064 in bank A. 0758-1024 *FD FRM Focus will not move to the commanded FRM 100 146 position. Tried all normal procedures to correct the problem, nothing worked. Called site tech, he said there is nothing he can do till daylight, he will need to go up to the FRM to work on it. I will continue to run the project, since last night I had the same problem and it eventually corrected itself. Site tech decided to come to the site and try to jar it loose by putting it in manual mode. 0800 Begin at Y. 0817 All readbacks ok. 0915-0917 *KP Autostowed. Power glitch.
