SGP/XSAPR/I4 - Testing/Maintenance Mode

The XSAPR was in a state of maintenance and testing during this period.  Known issues 
include:

Operating in single pol mode resulting in bad polarimetric variables (Zdr, RhoHv, etc.)
Incorrect calibration resulting in low Zh values
Intermittent transmitter failures
