NSA/MWRP/C1 - Radiometer thermally unstable

Between Dec 21 and Dec 23 the external temperature dropped to - 38 C. This caused a 
problem with the stability of the noise diode mount temperature and consequent problem with 
calibration.

NSA/MWRP/C1 - Hardware failure- Intermittent data

Data are intermittent during this time due to a failure of the analog board.
The calibration of V-band data may have slightly drifted due to power outages.

NSA/MWRP/C1 - Thermal instability- TKnd test

During this time the radiometer was thermally unstable . The noise diode physical 
temperature had sudden drops of more than 5 degree in several ccasions between 2/1 and 2/11. On 
2/12 the radiometer temperature set point was lowered of about 10 degree as a test. On 
2/27 a new analog board was installed in the instrument. Data after 2/27 show a slight 
change in calibration.
