PRIMARY FOCUS OF THE FTDX9000 DESIGN TEAM WAS CLEARLY ON RECEIVER
PERFORMANCE, PERHAPS THE MOST CRITICAL FEATURE FOR SERIOUS DXERS AND
CONTESTERS.  IN SUMMARY, THIS MEANS THAT AN OPERATOR WILL WANT TO BE ABLE
TO RECEIVE A WEAK SIGNAL WITHOUT INTERFERENCE FROM ONE OR MORE STRONG
STATIONS VERY CLOSE IN FREQUENCY TO THE DESIRED STATION.  THE KEY
PARAMETERS THAT WE MEASURE TO GAIN AN UNDERSTANDING OF A RECEIVERS ABILITY
TO EXCEL IN THIS RESPECT ARE MDS MINIMUM DISCERNABLE SIGNAL, A MEASURE OF
HOW WEAK THE STATION CAN BE SO WE CAN HEAR IT SELECTIVITY, A MEASURE OF THE
BANDWIDTH AVAILABLE TO SEPARATE SIGNALS BDR BLOCKING DYNAMIC RANGE, A
MEASURE OF HOW MUCH STRONGER THAN THE MDS A SIGNAL MUST BE TO CAUSE THE
GAIN TO BE REDUCED, PERHAPS ELIMINATING THE WEAK SIGNAL AND, PERHAPS MOST
IMPORTANTLY IN A CONTEST IMD INTERMODULATION DISTORTION DYNAMIC RANGE, A
MEASURE OF HOW STRONG TWO NEARBY SIGNALS MUST BE TO GENERATE IMD PRODUCTS
THAT CAN MASK OUR SIGNAL.  ALL PARAMETERS ARE LISTED IN TABLE 1, WITH
