NSA/MWR/C1  - no air temperature signal
DataStreams:nsamwrC1.00, nsamwrlosC1.b1, nsamwrtipC1.a1
Description:
When the new blower was upgraded by Radiometrics and reinstalled on the MWR, the air 
temperature sensor failed to properly report. It was determined that the wires carrying the 
signal to the analog board did not conform to the standard expected by the upgraded blower. 
The problem was corrected by changing the wiring and modifying the MWR software to read 
the signal from the appropriate corresponding channel.

NSA/MWR/C1 - Instrument problem, Heater problem
DataStreams:nsamwrC1.00, nsamwrlosC1.b1
Description:
The heater of the MWR was ON all the time even when the moisture sensor was dry. Jim 
Liljegren suspected a problem with the relay that activates the heater. The suggested action 
was to send the faulty assembly to SGP for repair and get a spare unit from SGP.
The spare unit was sent on 9/15 and was installed on 10/18.

NSA/MWR/C1 -  Incorrect time stamp
DataStreams:nsamwrC1.00, nsamwrlosC1.b1
Description:
On Sept 27 the motherboard of the MWR computer was replaced. Following the replacement, 
the date on the computer was not set to the correct time of day, therefore the date and 
time in the files were wrong. The time on the computer was reset on Sept. 30. Time stamps 
between Sept. 27 and Sept. 30 were later corrected based on gathered information, however 
they may have as much as 5 minutes of uncertainty.
