SGP/EBBR/E15 - AEM Home 15 Values High

Beginning on June 23, 1995, the home 15 value indicated greater than 70 at
times.  This indicates that the home 15 and 30 outputs are somehow being
electronically added in the AEM.  Home 15 values above 70 cause a data quality
message to be output in the site operations log as the stated acceptable range
for home 15 is 35 to 70.  However, no data is incorrect as a result of this
condition.

No replacement AEM is available and site operations was not able to
diagnose the problem.  At present, data quality is not jeopardized.

I will submit another DQR or addendum when successful repair or replacement of
the AEM is accomplished.
