[Elecraft] K3/K3s; Digital modes, specifically DV

[Bob Nielsen]

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.
