SB SAT @ AMSAT $ANS-202.01 ECHO Update - 20 July 2004 AMSAT News Service Bulletin 202.01 From AMSAT HQ SILVER SPRING, MD. July 20, 2004 To All RADIO AMATEURS BID: $ANS-202.01 The command team continues to work and test Echo. At the present time they are testing the satellite's software on the ground in preparation for general amateur use. The team continues reloading and testing software on the satellite. Telemetry data is also being collected when Echo is in the sun, to work on attitude determination. The satellite has been in a low power mode while software is loaded. The 435.150 MHz downlink is being used for this task. There are a few more tests to complete before the satellite is opened up for use by the general amateur community. This step will not signify the completion of commissioning by any means, but it has always been the goal of the command team to insure that the satellite's hardware is working properly first, and then open the satellite for everyone to use. Much more work and testing is yet to be done. The command team, at various times, following general use, will disable the current operating mode to compete the necessary tests. This will occur without prior warning. When we begin this phase, please consider the satellite in experimental operation mode. At the present time it is anticipated that Echo will be opened initially in 9k6 digital mode, via the BBS system. After running a few days in that mode the FM repeater may be enabled. All modes will start at low power and gather data while looking at the overall health of the satellite, - specifically the power consumption in each configuration. As the command team gains knowledge they will gradually increase the power, and again watch the data. The command team asks at the present time, that you continue to NOT transmit to Echo. Your patience in that regard up to this point has been appreciated. When Echo is ready, a BBS message will be posted on the Satellite, as they have tried to do from time to time to inform the 9k6 digital group what is happening with commissioning. Also a bulletin through ANS and on the AMSAT website will be issued. So, please continue to show restraint and you will be making your first contacts through Echo soon.
