You still build a transmitter and or receiver, but it is not a "whole
SSB rig" as mentioned.
Just a PA driven with a pair of D/A chips followed by a filter or tank
circuit to the antenna. The essence of an SDR.
At much higher frequencies, that could be mounted at the antenna to save
on feed line losses.

And what is going to be transmitting this IQ data? Where's the D/A
conversion?

Would it be easiest for the software to have a port for UDP IQ data on
both RX and TX?
Then we only need to add the operating frequency for the bottom of the
band to the software configuration for each UDP port number our
station can support.
That would open the application to any operating frequency without the
need to provide updates.
(that's how modern airborne radar works)

Seems foolish to build a whole SSB rig to convert the audio signal
from WSJT to RF when at low frequencies some direct synthesis should
be possible. Or am I dreaming?
