All ingress occultations at DSS 65 have amplitude variations +/-0.3 dB resulting from ramping and receiver filter ripple. All ingress occultations have about 16 dB lower SNR because telemetry is ON. Signals in egress starting at 1999/054-09:15:00 are extremely weak. There is no signal at all in egress starting at 1999/054-11:13:00. Carrier in the next egress (starting at 1999/050-13:10:00) has expected strength but it appears to be drifting, as though in 2-way mode with uplink ramping. 4 occultations (start times 1999/054-17:06:00 through 20:12:00, inclusive) were lost because of a scheduling change that moved the Nadir Test about a day later. 1 occultation (start time 1999/054-23:00:00) was lost to a gap in DSN coverage. Occultation at 1999/054-03:22:00 has largest spectral noise seen from a HEF to date. May be surface echo from HGA sidelobe.
