    The SRI 46-Meter Antenna at Stanford University in Palo Alto, California
    continues to set new distance records at UHF.  On 2000-02-08 at 1930 UTC,
    the 46-Meter Antenna detected the 1-watt 437.1 MHz CW signal from the Mars
    Relay on board the Mars Global Surveyor (MGS) spacecraft in orbit around
    Mars.  At the time of the detection Mars was over 307 million kilometers
    away.  This represents the first time an UHF signal has been transmitted
    and received beyond a distance of 2 astronomical units (AU).  This new
    record was accomplished by Dr. Ivan Linscott of Stanford University, Dr.
    John Callas of the Jet Propulsion Laboratory, and Dr. Michael Cousins of
    SRI International.
