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, Don W3FPR On 3/17/2011 9:37 PM, juergen wrote: > I would like to see a true SDR receiver from Elecraft.
