NSA/MMCR/C1 - MMCR Data Quality

Description:
The NSA at Barrow was experiencing technical difficulties related to hardware problems.  
Water was found in a waveguide, which may adveresly impact sensitivity.  An up-down 
converter problem was also found.  This problem may also impact sensitivity.  The quality of 
the radar calibration during this period is unknown, but will be determined at a later date.
Suggestions: 
Corrections will be made on a case-by-case basis after screening through an expert system.
