Rick and I looked more carefully at the 2oct06 data.  The "ant. 10" phase
jump actually occurs with different magnitudes on different antennas, with
some showing no noticeable effect, and others showing many 10s of degrees.
I thought this was just ant. 10 because it showed up so consistently, and
10 was the reference.  Alas not so...
