[Elecraft] KX3 "Full" SDR

[Craig Schroeder]

Happy New Year,

I want to move into the hobby aspects of SDR and have narrowed my list to the KX3 with 100 watt Amp or a Flex 3000.  I have been told that though the KX3 will connect to a PC it is not a "full" SDR radio (my understanding of "full" is in regard to signal processing but there may be other factors implied that I am not aware of being new to the SDR world).  

If this perspective is on target, what are the important SDR limitations with the KX3 that I should consider?  If there are no important limitations, I do like the form factor and knobs on the KX3 over the Flex software-only interface.

Thank you,

Craig Schroeder
