           Operator is Jim Ogle.                                                
           VCLOCK and gps delta checks okay.                                    
     0131  Begin.

0636-0740 *FD AZ#2 fault, blown fuse likely, antenna stowed,     19601  100   64
           site tech en route.                                                  
0839-0853 *FD Put antenna in standby to clear AZ#2 ACU fault.    19601  100   14
0924-0126 *FD Put antenna in standby to clear AZ#2 fault.        19601  100  962
           This clears the errors, but always when I repoint                    
           the motor currents spike again within a minute or                    
           so. Continued to try, but not able to repoint for                    
           very long without motor currents spiking again.                      
          &Finally called site tech again.

           azimuth rotation of the antenna. Site tech waiting                   
           for daylight to inspect.
