Subject:
TWP/MMCR/C1 - Reduced sensitivity due to LNA failure
DataStreams:twpmmcrspecmomC1.a0, twpmmcrmomC1.b1
Description:
The low noise amplifier (LNA) failed resulting in a loss of approximately 26 dB of 
receiver gain and sensitivity.

The reflectivity values should be correct but sensitivity is reduced.
