Date Time Component Description
04/12/2011 14:28:45 406 RECEIVER Swapped 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.
01/05/2011 00:00:00 406 RECEIVER Following 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.
05/05/2009 13:40:00 406 RECEIVER TO POWER UP A-SIDE CONVERTER AND RECEIVERS AND A-SIDE TRANSMITTER. DISABLE 121 & 243 RCVRS. SET ATTENUATORS TO 0 DB FOR PDS CHANNEL AND 2 DB FOR 406 RCVR CHANNEL.
