The high frequency bands have now been checked as well.  This is
the first time we have used widar with all antennas to verify that
the antennas still work at the high frequency bands.

I neglected to explain in my first message that delays have been
set only for IFs A and C.  We will have to reorganize the CBE and
MCAF to get data from the other IF pair.  Crossed hand delays have
not yet been checked and are almost certainly wrong.  This also
awaits reconfiguring the correlator and SW to supply all four
polarization products.
