[Elecraft] RX I/Q output planned or thought about for the K3/P3?

[Don Wilhelm]

The K3 *is* an SDR as long as one defines an SDR to be a radio whose 
functions are defined by software (firmware).
If your view of SDR is a radio that must connect to a computer 
soundcard, then the K3 will not qualify because the "computer" is inside 
the K3 in the form of dedicated processors.

Any radio that uses DSP for modulation, demodulation and filtering (plus 
other things like NR and NB) is an SDR as far as I am concerned - as 
long as the software to do those functions can be changed.
