An attempt was made today to see what works and to try to get the
newest antennas pointing well enough for a collimaiton run to be
successful.  A good collimation run is now needed for the newest
antennas.  After the pointing is taken care of focus will be checked.
The only unexplained problem is ea09 at K band.

K band problems:
ea04 was out of service
ea09 was dead.  It looked like there was no receiver.
ea12 no receiver

Ka band problems
ea11, ea13, ea14, ea16, ea17, ea18, ea26 all have no receiver
ea03 AC was dead because the L302 was in standby.
ea12, ea22 were weak and improved with a collimation adjustment
ea12, ea21 needed small delay adjustments


Q band problems
ea05 was out of service
ea12, ea17 have no receiver
ea07, ea22 were weak, but improved with a collimation adjustment
