Paul Marsh reported the following on the Hearsat-L newsgroup:
I think I have re-found the Chinese Chang'e-2 lunar orbiter downlink. I've been monitoring it for a few hours, and can see both Doppler inversions as it orbits the Moon.
http://pjm.dyndns.org/sdr/change2a021110.jpg shows the signal, downlinking on 2210.800 MHz nominally.
I also caught this fft http://pjm.dyndns.org/sdr/change2a021110a.jpg showing the Doppler inversion.
Can someone else with S-Band facilities try to track this orbiter and report back its signal strength etc?
Also Nils in Germany confirmed Paul's observation:
I can confirm the Signal on 2210.816 MHz from Moon with upward doppler direction
at ~ 12:30 UTC. The Moon is about to set here currently, the following FFT was taken at 3°Elevation only. This is using a 1m mesh dish + EME103B LNA and Winradio Converter into an ICOM IC-R7100 with SDR-14 on the IF out.
