[Elecraft] Understanding the KX3 Block Diagram - SDR!

[Edward R. Cole]

One should also remember that the K3 is ALSO a SDR.  The 15-KHz 
second IF is a SDR, so the KX3 is a beneficiary of the design lessons 
learned in making the K3.  I suspect technology for a "good" zero IF 
SDR was not as available when the K3 design was done (and I'm sure 
some other design considerations).

Rick Campbell was a pioneer in the direct receiver field, however his 
R2 was an analog receiver, although a step toward a true SDR.

One thing I am looking forward to doing is a A/B side by side 
comparison of the KX3 and my SDR-IQ.  The other comparison is with my 
K3, of course.  I wonder is March 12 will see the beginning of 
shipments? Hope Hope
