Lunar Reconnaissance Orbiter

Launched on the 18th June 2009 and carries a 5 watt S-Band transmitter at 2271.2MHz with two S-band omni antennas, 2 medium-gain horns and a 75cm HGA. There is also a 40 watt Ka-Band transmitter at 25.65 GHz to the 75cm HGA. It is possible to hear the uplink to LRO via EME by looking for a locked signal from LRO on 2271.200MHz, then tuning to 2091.4MHz and looking for a spread signal such as the example below:

Lro uplink 310118
