Date Time Component Description
04/12/201114:28:45406 RECEIVERSwapped from A-Side to B-Side (Backup) Converter, Receivers, and Transmitter. Disabled 121 & 243 Receivers. Set Attenuators to 0 DB for PDS Channel and 2 DB for 406 Receiver channel.
01/05/201112:00:00406 RECEIVERFollowing the eclipse on January 4th, it was reported that the SARR 406 receiver output frequency jumped by almost 1KHz. Telemetry shows that the 406 Oscillator temperature did not recover to the values seen before the eclipse, and is currently operating at 0.7 degrees cooler. The impact on the LEOLUT earth stations is relatively minimal, as it only affects the combined SARR/SARP processing.
