[Elecraft] [Elecraft_K3] KR3 SW Receiver.

[Don Wilhelm]

  John,

The K3 is an SDR.  It does not depend on an external computer to support 
its operation, but by all proper definitions of an SDR, the K3 qualifies.

I am not certain what your "true SDR" means.

If your definition of an SDR is one that is a "black box" that requires 
a computer to be a fully functional device or one that requires a 
spectrum and waterfall display, then I believe your definition is limited.

The K3 has the SDR computer built-in, and the downloadable firmware can 
alter its functions and characteristics drastically - that is the basic 
definition of an SDR.  I believe you are looking at the presentation 
aspects of other SDR radios that depend on an external computer for 
support, and that is not the essentials of an SDR - an SDR is a radio 
that can be altered by installling different firmware - a pure and 
simple definition, and the K3 does qualify for that.

If you want the latest on computer assisted SDR designs, I suggest you 
look into the Softrock-40 group on Yahoo, there is a lot of good 
activity, and the hardware kits are available at reasonable prices.

73,
