The ground pre-cal and post-cal levels seem particularly solid. Echoes were observed in real time on all four channels. There was some confusion during operations about how the S-Band receivers were assigned to the microwave feeds; but Gene Goltz and Danny Kahan documented the ground pre-calibration steps well enough that the digital files have been correctly matched with their respective polarizations. X-Band carrier levels fluctuated +/-0.5 dB both before and after the surface observations. The reasons are not known; but Jeff Berner (JPL) has noted unusual phase noise recently when the spacecraft is in the one-way configuration and amplitude flucutations may be related. Phase noise tests are scheduled for day 202. There is strong interference from an unknown source in both S-Band channels at about 19:10 and 20:50; both instances lasted about one minute. The first is at the beginning of the surface observations; some science may be affected. The second interference was during the 70-m antenna slew from Mars tracking to zenith, and there will be no impact on science.
