OK, so Mars isn't really considered DX in the DSN arena but it's too low on the horizon for my 1.2m so I dragged the 2.4 out. For all doubters out there, the Fortec works quite well on 8.4GHz. Here's MRO Mars Reconnaissance Orbiter on 8439.255MHz. Quite a decent signal:

Much closer at 112,000,000km on 8445.569MHz, OSIRIS-REx OSIRIS-REx Mission but at only 10 degrees elevation it's close to the trees:

Plots are inverted as the LO is high so Doppler changes are opposite to those shown.
 
Nice catch!
 
Now go tell the orbiter to look for signs of life down there.
