Data collected during Venus Express bistatic radar on days 166, 168, and 170 and data collected during Mars Global Surveyor occultations on days 165-190 at DSS 43 show both dropouts and sudden, brief increases in sample power (up to 1 dB, lasting approximately 1 second, and spaced by minutes). There may be a few instances of dropouts in these MEX BSR data, but they are very limited in comparison with the other cases. A surface echo is easily seen in the quick-look plots from both X-Band channels at the beginning (05:50) and end (06:51) of the experiment. We believe, from real-time monitoring, that an echo is also present in the middle; but it isn't obvious from the quick-look plots. There is no obvious S-Band echo in the quick-look plots.
