Subject:	GRW/MWR/M1 - Incorrect instrument computer set-up
DataStreams:	grwmwrlosM1.b1, grwmwrtipM1.a1
Description:	Starting late on 07/11 the instrument began to have very brief (< 1 min) data outages every few hours. By 07/12 data had become noticeably incorrect, particularly the PWV, LWP, TB23, and TB31. At ~17 Z on 0713 the missing data / no data available flags became more frequent. The problem was identified as improper settings of the instrument computer and was solved on 8/9.

Subject:	GRW/MWR/M1 - Erratic brightness temperature
DataStreams:	grwmwrlosM1.b1, grwmwrtipM1.a1
Description:	Around 12 Z on 7/20 both the PWV and 23.8 GHz brightness temp values began to diverge from those of the MWRP. By 7/22 both the LWP and 31.4 GHz brightness temp had followed suit. At 0600 Z on 7/22 multiple (10-20), brief (<=1 min) data outages began appearing hourly. The problem persisted intermittently until 8/9. On 8/9, changes in the settings of the computer restored the proper functionality of the MWR software.
