My thanks to someone who emailed me earlier this evening.
Curiosity transmits around 401 MHz but the transponder on the Mars Reconnaissance Orbiter has a CCSDS Forward Frequency in the 437 MHz Amateur-Satellite Service band.
We well know that 435-438 MHz is shared with the Military but 432-438 MHz is of course a Space SAR Band, and I understand general Space usage extends beyond that.
This paper describes the operation of the MRO (see page 34 onwards) http://descanso.jpl.nasa.gov/DPSummary/MRO_092106.pdf
