To me the K3 is not an SR (Software Radio) but an SDR. Not all the
functionality is implemented in software, but enough of it is so the
software constitutes the lion's share of the rig's functionality. The
software isn't the radio but it defines it. SDR.

Not many radios from the 1980s are SDR, Affordable DSPs from the 1980s
didn't have the bandwidth necessary to sample from the I

For example, early SSB rigs used a balanced modulator that nulled the

that entirely in software. How does the K3 generate SSB?
In software.

The whole question really is, "What is an SDR?" As long as we all get
to choose our own definition, we'll have widely varying opinions :-)

Sorry, but I'm not sure I agree. By that definition many radios since

My definition of an SDR is a radio that could be radically changed in
functionality by a software change. Perhaps the K3 fits that definition
with firmware changes. But does the K3 modulate or demodula
So if one owns a K3, does that match your concept (or the ARRL's) of
an SDR? How would YOU answer?
It is IMHO.
SDR means software defined, and the K3 is defined by software. Whatever
gets through the roofing filter is handled by DSP in transmit and receive.
This is quite different from PC-
Currently, on the ARRL home page, they are running a survey:
How familiar are you with Software Defined Radio (SDR)?
And the possible radio-button answers are:
* Very familiar! I own a software-defined radio
* I don't own SDR gear, but I've been studying the technology
* I've heard of it, but th
