The mcHF is nice but it is still a work in progress.
But it does show what can be done.

The more I look at the mcHF, the more impressed I become. Once I
get caught up with my current projects I'll seriously consider
getting one.
The FreeDV code and more importantly Codec2 are indeed open
source. I don't know how much room there is in the K3/KX3/KX2
firmware to add something like this but if possible, it would be
quite useful in getting more FreeDV activity going. in the
meantime, I'll make up some cables to connect my KX2 to my SM1000
and give it a try.

As I understand it the
FreeDV code is open source so Elecraft would not need to
reinvent the wheel.

Strangely
the mcHF website doesn't seem to mention it but
that's great.

The
mcHF does indeed have FreeDV built in RX and

I'm
running ver 1.5.7 of the firmware (Ia little
old as I have not updated it recently)

While
the mcHF has some digital audio
circuitry, I don't believe it
provides a digital voice mode.
FreeDV is a very narrow-band (1.1
kHz) digital voice mode using the
open-source Codec2, developed by
VK5DGR. One can run FreeDV without
a
computer using the Rowetel SM1000
adapter
(https://www.tindie.com/products/edwin/sm1000-freedv-adpapter/).
This
should work nicely with a KX2 or KX3
for portable FreeDV operation. I
haven't tried doing that but it
looks fairly straightforward.
