[hpsdr] TeamSpeak audio 2019/Dec/28

[ad0es]

Hi,

Actually I wrote a complete suite of software for Minerva, just never 
got a Minerva...

This is all working code (via an Anan 200D with special firmware), for 
an idea of what is possible see:

http://ad0es.net/dfcSDR/latestAthena/index.html
http://ad0es.net/dfcSDR/index.html
http://ad0es.net/flprogs/hydra/introduction.html

It can directly connect to a modified fldigi via tcp-ip pcm packets, 
bypassing the audio stuff completely.
It also works with stock fldigi, qtRadio, Thetis, wsjtx,  or any other 
program using the audio system for linkage.
It also works with gnuradio scripts, via IQ streams and I *think* gqrx 
via IQ, which is based on gnuradio
(can't remember for sure, I stopped development several years ago). I 
had a nice setup of 10
bandscopes based on gqrx spread across 4 HD monitors.  You could click 
on the display and immediately
tune to the signal.

I would /*LOVE */to restart the project, but I need real dfc hardware to 
take it any further.
