The KX3 is, generally speaking, a subset of the K3 optimized for  
ultralight, portable operation (1.5 pounds, vs. 9 to 10 pounds for the  
K3). It also adds SDR features, attached keyer paddle, and some  
additional versatility for mobile operation (such as a mic with UP/DN  
buttons, and eventually a mobile mounting bracket).

The K3 adds:

- internal 100 watt PA and ATU options

- narrow crystal roofing filters (down to 200 Hz) for
   outstanding close-in dynamic range in contest conditions

- superhet receiver with very narrow per-ham-band filters
   for the ultimate in out-of-band signal rejection; optional
   SWL-band filter modules for both main and sub

- fully independent sub receiver option with
   performance identical to main receiver, allowing
   monitoring of both TX and RX frequencies simultaneously
   with different modes and bandwidths, and a separate
   antenna input allowing independent band monitoring and
   diversity receive

- full-size front panel with convenient control of
   many additional DSP parameters, etc, and more menu
   entries for customization of operating features

- close integration with the Elecraft K-line (KPA500 amp,
   P3 panadapter, KAT500 ATU)
