|DataStreams:||grwwacrspeccmaskcopolM1.a0, grwwacrM1.b1, grwwacrspeccmaskxpolM1.a0|
At approximately 16:27 GMT on 20090727, txpower began intermittently dropping out and reporting slightly negative values. This issue continued intermittently through 20090807 when it stopped occurring. The problem resumed 20091006 and continued to occur on a daily basis until the monitor detector was replaced 20101019. The transmit power as measured by the detector after replacement was approximately 1.3 dB less than when it failed. Reflectivity measurements have a +0/-1.3 dBZ of additional uncertainty for this period of time.
