So, question: Is the unit capable of keying FSK, or do I have to set
up as AFSK? I prefer FSK, if possible.

You must use AFSK.   The MFJ-1204 is a clone of Tigertronix Signalink -
it is a USB sound card with VOX based PTT and has no support for FSK.

I received the MFJ-1204 and have it working just fine on PSK31 (XMT and
RCV) and RTTY RCV. I can't get it going on RTTY XMIT. I am using WinWarbler
for RTTY control which uses MMTTY as its engine.

I can get it to key (single tone) but no modulation.

I had a similar problem with my MFJ-1279, so I expect it is a setup issue
in my software or the rig itself.
