 Something else to consider is that the "old" bird swtiched modes in the middle of the pass.  I do not have any idea when it switches from Mode B back to Mode A since I am not capable of operating Mode B. 
However, I can speak to it switching from Mode A to Mode B in the middle of a pass. I had that happen several times and even in the middle of a QSO.  I haven't been on mode A in several weeks due to a new job, but last known it would switch from Mode A to Mode B around 2325z  and seemed to be getting a little later ever day.
