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

Max, all I've really used for RTTY has been FSK, using my MKII as the
interface. I'm sold on the fact that the signal is probably cleaner. With my
new KIO3B board I was hoping to get to a single-cable interface to greatly
simplify my setup. At least, I thought I remembered reading that this was
possible in Elecraft literature. I was really sick of the rats-nest of wires
behind my K3. While I love the K3, sometimes I wonder if a Flex would be
less hassle overall simply due to the simpler interface.

I'm skeptical anyone has made RTTY with without some kind of addition
interface beyond a simple USB cable since ASFK-A keying with VOX appears
broken. Other digital modes shouldn't be a problem since DATA-A works.

One of my friends, N7US, has been suggesting the MORTTY solution. Yet
another interface. Sheesh. Why can't it just be all built into the K3?
There's probably a good technical reason. I'm a EE who works on transmitters
professionally but don't know the nuances of USB interface. I guess it must
be hard to make it work. Or perhaps it's a limitation of how the K3/K3s is
architected.

It would be nice once the lockdown in CA is over, if one of the Elecraft
people could chime in on this.

BTW I'm about 1/2 thru your FSK video. Very informative. Thanks for putting
it together. If I get an MORTTY I'll be sure to watch your other video.
