So I have combined the JPL/DSN SOE (xd066a.00.tsoe) with the List of Events provided by ESA for the experiment on 3 April to get something that should work. The events to about 23:55 are reasonable. After that, I'm really guessing. MEX goes into eclipse at 00:12, so the LOS at 23:56 is probably because they turn off the transmitters (xd066a.00.tsoe says only that there's LOS). It doesn't appear that DSS 43 will see a direct signal after the first slew begins (around 22:37), so it may not matter whether my guesses are correct. The DKF for this date (xd066a.00.dkf) is written as though there is a radio science occultation between 00:33:38 and 00:42:18 (lines 647-651). That appears to be a mistake; the radio science activity is confined to the bistatic radar.

The observations completed on 10 April yielded echoes in both X-band polarizations that peaked at 25-30 dB SNR in real-time displays, slightly stronger than the echoes we saw on 3 April. The calibration work on the 3 April data is largely completed and we expect results shortly. There seems to be a bottleneck in the playback system, so we have not received any data from the 10 April experiment; but there is plenty to do in the meantime. The one experiment in February and the two April experiments were all done using DSS 43 near Canberra. The ground procedures seem to be sound and we will be applying them (with minor modifications) to the DSS 14 experiment which will be conducted on 24 April. The support provided by DSN operations and engineering staff has been extraordinary. The first two experiments gave us single measurements of dielectric constant near Argyre Basin; the data from 10 April should give us a measurement within Hellas. An experiment in early July is now being planned in which the spacecraft will track the specular point, allowing us to make independent measurements at dozens of points, vastly improving the science return for each scheduled event.
