I copied the LRO S-Band downlink last night, very strong signal on the nominal frequency of 2271.2MHz. Please see my FFT at http://pjm.dyndns.org/twtr/lro_2271223.jpg - at the time the moon was setting over on the west horizon, and was at about 15 degrees elevation. I also checked for signals from Grail-A and -B but nothing detected.
