The target on 2006/021 was Hellas Planitia, and the observations were conducted very soon after pericenter meaning that Doppler shifts and Doppler spreading were very large. In fact, we monitored the carrier using the 250 ksps option on the receiving system, the first time we have gone above 100 ksps. Echoes were only visible on S- and X- Band LCP in real time; the RCP signals were expected to be weak because the incidence angle at the specular point was only 32 deg. It is likely that we will need the 100 ksps data for science analysis because of the extreme Dopplers; we collected about 30 minutes of noise data during the ground pre-cal to facilitate this work. Between the pre-cal and the beginning of tracking, we lost the S-RCP signal for about 15 minutes. We lost it again twice later, for about 10 minutes each time. Fortunately, the outages were during (mostly) periods of little activity; but we did lose about 10 minutes from the post- cal. Personnel from the station and from JPL investigated, but were unable to diagnose the problem except to localize it to the S-RCP maser. By the time we were ready to begin the experiment on 2006/022, the maser had been declared "red," limiting us to three downlink channels. I think the data from 2006/021, despite the interruptions, are probably OK. For what it's worth, S-RCP was expected to have the weakest echoes of the four channels; if we were going to lose one, that was probably a good choice. On 2006/022 the target was Mars northern plains (Utopia Planitia). Echoes were visible in all three channels, with the two X-band echoes being roughly equal in strength. Since the HGA tracked the specular point, we were able to observe the reflections for a full hour. There was a minor problem with the X-LCP mini-calibration, which means we will have to compensate for the fact that noise diode energy is superimposed on the X-LCP echo for a few minutes at the beginning. With the exception of the maser problem on S-RCP, I consider these two experiments to be very successful and look forward to having the opportunity to collect more specular track data in the future. When we have something to look at, I'll plan to share a figure showing an hour's worth of Mars echoes.

No, there was never any problem with S-LCP, which has always been on the HEMT (I think). The S-RCP maser had problems and eventually died; but, since the HEMT is being used for LCP, there is no backup and we ran with only three channels. John Klose (and the station) both suggested swapping in the HEMT; but I don't think they realized we couldn't give up LCP in order to receive RCP. Eventually we got it straight with the station. If you think there is a third LNA for S-band, then we should look into that. The chart I got from Art Freiley last year shows only a BLK-4 and the HEMT available for S. We need two channels, so there's no backup when one of the two known LNA's is red.
