One caveat here... if you happen to set the ALC levels for low freq
tones, say 600 Hz, then end up using 2150 Hz, that level may very well
be well off, overdriving or underdriving while the radio tries to
compensate with varying power levels or accidental distortion. So one
should be cautious of that or ALWAYS use the same tones.
I've made that a non-issue for RTTY by using FSK but in PSK (sideband
doesn't matter) or others, the same issue remains.

This is grossly oversimplified, but it's a place to start: the
software makes noises, the transmitter transmits them, the remote
receiver receives them, and the software at the other end turns them
back into letters on the screen.
Different noises for RTTY, PSK-31, Olivia, Throb, Hellescriber, etc.
but the technique does not change, and once you get a program working,
you likely don't need to change anything but the VFO to change modes.
I'd start with PSK-31 because it's popular. DATA A will do fine.

I'm also interested.
Are you saying that the K3 should be set to DATA A and the controlling
software on the PC will handle TX/RX, whether it's PSK, RTTY etc.?
