<p>Hi,</p>
The Athena/DFC code pretty much does that now.<br>
Athena sends complexFloatIQ samples to Aether, which sends them to
all the running Hemeras.<br>
Hemera converts to PCM samples, BUT doesn't send them to the sound
stack. It instead sends the PCM samples<br>
directly to flRadio (modified fldigi) via a tcp socket. I wrote a
"sdrsound driver" for fldigi that gets its PCM sound samples<br>
from the socket instead of the sound stack. This both improved
latency and quality of the decodes.<br>
<br>
The final step would be to make fldigi understand IQ data directly,
but I suspect that would be a major project.<br>

would be nice to have that. It would require developing some kind
of standard for the UDP interchange and getting the digital mode
applications on board along with our console applications. I like
the idea; for me at least, time is a little lacking for now.
