Subject:	SGP/CSAPR/I7 - Elevated Noise Floor
Affected Datastreams:	sgpcsaprsurI7.00
Description	The noise floor has been fluctuating throughout the day, but starting in September the severity of the problems has increased. It is difficult to discern meteorological echo from the noise.

Subject:	SGP/CSAPR/I7 - Missing Sectors
Affected Datastreams:	sgpcsaprvertI7.00
Description	Periodically, there would be missing sectors or elevations in the data.
