Here's an interesting document describing the communications relay capability in the Mars Reconnaissance Orbiter, used as a relay for Curiosity and other Mars missions.  The UHF links to the ground, er, Mars are in ~437MHz and 400MHz band.  While we might share the same frequencies, they're using something a bit more efficient than 1200bps AFSK FM modulated AX.25 on the RF links :-)

This paper references other documents in the series that also look like some interesting reading:
