[Elecraft] K3 doesn't work in AFSK-A mode but DATA-A does work. What's broken?

[M. George]

Joe, I can confirm the same success for using AFSK A with VOX to key the
radio... and just for kicks and giggles... I have a K3S and a K3, the K3
has the KIO3B install and I tested the AFSK A setup with MMTTY and N1MM on
both radios.  *The conjecture / reports that it only works on a K3S is a
total red herring as Wes and Rich have reported? Wow that is a tangent for
sure...*  They (K3S/K3 with the USB KIO3B) work exactly the same gents,
there is nothing magical about the K3S.  I actually made a quick and dirty
YouTube video for you (Joe N9OK) and I'll send you the link to the video as
soon as it's published.  It walks you would a setup for AFSK A direct with
MMTTY and shows a test... and shows you all the configuration screens so
you can pause the video and compare to your setup. I then reference that
instance of MMTTY in N1MM and show the setup there.... and I work some
stations... all using AFSK A on a K3 with the the KIO3B using VOX to key
the radio. It's a March miracle.
