NSA/MPL/C1/C2 - No cross polarization data

Even though the polarization voltage was reported as switching between circular and cross 
polarization states, there was no cross polarization taking place because the 
polarization box had not been recycled following a system reboot.

You will not be able to create depolarization values.  However all other processes, such 
as cloud base determination should be ok.

NSA/MMCR/C1/C2 - Wrong Polarization

The new antenna was mistakingly set to transmit/receive in circular polarization instead 
of linear polarization.  The result is that reflectivities are much lower than they should 
be.  Since we only measure on polarization channel, there is no way to apply a 
correction to go from circular to linear polarization.
