    Was anybody monitoring/listening on 
    216.98 mhz to the NAVSPASUR echos when 
    the shuttle went over north central 
    Texas?  Multiple echos?  The Lake 
    Kickapoo CW transmitter was almost
    directly underneath the apparent 
    The apparent breakup may have been east
    of the NAVSPASUR illumination fan, but
    there is always a possibility of late
    multiple doppler sequences.
    Since NAVSPASUR is always "on", and signal
    reflection is passive, it is possible to
    capture doppler echos.
    A few info links for NAVSPASUR reference:

    For signal samples:
    Search GOOGLE  or whatever for "navspasur"
    and "wav" and etc  references.
