The Yutu Lunar rover was launched by China along with the Chang'e'3 lander on the 1st of December 2013, and made a soft landing on the moon on the 14th of December 2013. The original mission plan was for a lifetime of 3 months, the rover significantly exceeded that. The rover downlinks on X-Band and is rumored to also carry a UHF link for short range communications with the Chang'e'3 lander.
The rovers primary frequencies are as follows:
The rover downlink on 8462MHz sounds like this:
And a reflection off the moon of the command uplink sounds like this:
There was a lot chatter on the @UHF_Satcom Twitter feed about the discovery of signals from the Yutu rover, a few folks asked about the antenna in use at the UHF-Satcom ground station so here are a couple of photos of the dish illuminated by the Moon light. The antenna is an old NEC 1.8M diameter dish from the early days of Ku-Band satellite TV. It is built on a customised mount giving 360Deg azimuth coverage, and about 10deg to 60deg elevation. To the right of the dish you can see the 'novelty garden tool store' AKA a SCOT terminal for ship-board X-Band satcom. The LNA in use is optimised for 8.4GHz and was built by EB3FRN and M0EYT specifically to be an excellent low noise amplifier for deep space applications. Behind the primary LNA is a surplus X-Band amplifier donated by DD1US who runs the awesome 'Sounds from Space' website. The FFT waterfall images you can see above were generated by the Spectravue software from MoeTronix and the Software Defined Receivers in use are the RF-Space SDR-IP and a custom 'QSDR' solution. There is also some preliminary data regarding analysis of the downlink signals collected at UHF-Satcom over on r00ts excellent pages.

The gallery of FFTs below shows signals received from Yutu or via EME from the command uplink in China. All frequencies shown are the IF so 8GHz should be added to get the RF receive frequency.
