           UT 20:08:16 recording in bank B on module NRAO-158.                  
           Called site tech, having him remove the module in                    
           bank A (fully recorded) and keying off the module                    
           in bank B. Will issue a software reboot of the                       
           Mark5 unit, hopefully this will bring it up.                         
           Once Mark5 is rebooted, will have site tech key on                   
           module and try to restart recording.
