Still have a glitch in the Main Chain right channel in satellite box 3200715. We have eliminated cables and OSEM as the problem source. Swapped SB 3200715 and SB 320078 and problem stayed on MO Rt. Moved cables back to original position.
 
  We swapped cables on the AA channel and the AI channel. Glitch moved from MO Rt to MO F1; possible problem in the AA or AI chassis. Filiberto is going to do some more testing this afternoon to determine which chassis is at fault.
