Early in the design process of the K3 we explored various methods by 
which we could obtain dual receive capability.  Such capability was a 
basic design requirement.

Putting in a default "dual watch" system means an additional mixer and 
synthesizer while providing limited flexibility.  A lower-performance 
second receiver would not stand up to the severe operating conditions in 
which we wanted the K3 to excel.  Either approach would add significant 
cost to the basic radio, requiring people who did not want such features 
to pay for them while denying a high-performance second receiver option 
to those who might want one.

In the end, we concluded the best approach was an independent, 
high-performance second receiver.  The KRX3 is the result.  It provides 
the same performance as the main receiver.  It enables diversity 
reception.  Users of the K3's diversity mode quickly realize its 
benefits when chasing weak signals.

And the price is shockingly low!
