Subsystem History:

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	12:00:00	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.
