   COMMENTS:  AWS 8904 HAD CEASED OPERATING IN JANUARY OF 1983.  THE STATION FORMERLY AT SIPLE (AWS 8909) WAS PLACED AT DOME C WITH A NEW SET OF ROM'S TO MAINTAIN THE SAME ID, NAMELY, 8904.  A NEW BOOM WITH NEW SENSORS AND ANTENNA WAS ALSO INSTALLED.  THE OLD STATION HAD FAILED DUE TO A FAILURE IN ONE OF THE ROM CHIPS WHICH PREVENTED THE INTERNAL PROGRAM FROM CYCLING.
