23rd May 2010 The JAXA Planet-C (AKATSUKI) and Ikaros spacecraft have been received at X-Band. The main problem currently is that the elevation of these two only peaks around 15degrees, therefore a significant number of Tree dB exists in the path. The spacecraft were launched at 06:58:22 Japan Standard Time on May 21 2010.

Planet-C this was captured at 20:09z on the 23rd May 2010. The downlink frequency as received was 8410.8055MHz. As can be seen from the FFT screenshot, the signal is reasonable, peaking around 10dB over noise in 0.38Hz bin bandwidth.
