As always, Dr. McGwier's comments, in addition to being apposite to

If the OEM and/or third parties do not routinely write more S to
significantly expand range of capabilities and behaviors that the D in SDR
represents, then trying to decide whether a particular piece of HW is an SDR or
not is purely academic... At least from an end user's perspective..

Now there we can all most certainly agree. If they don't do the S part
often enough to make it useful or at least exciting, then the utility of
the S part is to the manufacturer and not the user.

So Bob,
The TNF is the penultimate effort for me... and I am working hard on the
ultimate for me for the year now. FINGERS CROSSED, I still have 16 days
HAHAHA
What is it going to do?

Let me guess, if you tell me, you'll have to kill me!

Hi Robert,
Flex used to sell a Flex 5000C that was self-contained and ran standalone.
That wasn't an SDR??? By your definition it wasn't, but I would disagree.
A reasonable definition of SDR
I find this to be a religious topic that isn't a winnable discussion.
The bottom line, however, is that both are fantastic radios and you can
have hours of fun using them. The K3 is a bit too small for my tastes in a
box radio (you know what they say, Big Feet: Big Knobs) but its a
tremendous

Actually, the ability to function without a computer is not the real

computer is embedded in the hardware.
The actual definition of SDR is just what it

I am waiting for the addition of software defined transmit antennas
(SDTAs).
From Wikipedia:
A *software-defined radio* system, or *SDR*, is a radio communication
system where components that have been typically implemented in hardware
(e.g. mixers, filters, amplifiers, modulators/demodulators, detectors,
etc.) are instead implemented by means of software on a personal
MY Cell phone, a Motorola Android is an SDR. But I don't drag a pc on my
back.

The K3 is a quality product. There is no reason for its manufacturer or
its users to get caught up in us too, us too.
The K3 may be the last great conventional radio while the Flex is the first
of the new way of doing things. At least the first to get any meaningful
market penetration.

Why are we even discussing this? The K3 comes with Kool-aid and the Flex
comes with EGG-NOGand cookies if you're lucky. Elecraft makes really
good radios and so does Flex, no question about it.

I agree, they're both excellent radios.
We're discussing it because a lot of people don't have a clear
understanding of what a Software Defined Radio actually is.
Heck, I even find it hard to keep these things straight anymore:-)
The line between what most people would call a true SDR,

Not saying that a K3 isn't a fine radio. My personal preference for the UI, is
a flex with no knobs.
