Gene, Danny:

This is my recommendation for the MEX bistatic radar operation Friday night;
it will be challenging.  The pre-cal has been reduced to 2 hours (as we
requested), the TX ON and first slew are done in occultation, the BSR is just
after periapsis, the X-band carrier and echo are separated by more than 70
kHz, the X-band echo width may be on the order of 30 kHz, the drift is 3
kHz/min, almost all of the echo will be in LCP, and we need to collect some
noise baseline data at 100 kHz in case we need to do our processing at that
sampling rate.  The total 100 kHz data volume will be twice what we're used
to.

Essam says he may join us.
