The Chandrayaan-1 mission is a Lunar Orbiter. The spacecraft uses 0dB gain omni's with about 4.8dBW for S-Band downlinks and a 33dB gain HGA with 6dBW for its X-Band downlink. On X-Band the space-craft is an easy copy, whilst S-Band needs a little more patience.
8th November 2008 - S-Band signals on 2230.800MHz from the satellite are detected
6th January 2009 - Another nice signal from Chandrayaan-1's X-Band downlink on 8484MHz has been received
7th February 2009 - Chandrayaan-1's X-Band downlink on 8484MHz has been received, a reasonable signal can be seen;
