Amateur Observers Hear From Chang’e 4

Edgar Kaiser, DF2MZ posted to twitter a very interesting plot showing a sinusoidal signal on 8470MHz on X-band.  This is a co-ordinated frequency by China with the ITU for Lunar Lander.

The one mystery they’re still working to solve: it appears as if Chang’e 4 is 90° out of the expected plane.
