We removed the east door from ham 3 and both doors from ham 2. We are ready to remove the west door on ham 3, however C 3 ham door covers are rare, therefore we subsituted with dome covers and used all of those. We will replace the subsitute covers with the appropriate covers when they arrive, hopefully Monday. We also installed viewports (serial #s) 23&26 on the H 1 MC input tube.
