[hpsdr] Metis/Ozy Together on Atlas

[John Marvin]

Until you posted I hadn't realized that Winrad and friends had any 
support for HPSDR, and if so, why it only worked for Ozy.  It looks like 
the author had the original good idea of have extio dll's to isolate 
hardware dependencies, and even extended the interface. But if the short 
look I took is correct, it looks like when he decided to add HPSDR 
support he didn't extend the extio dll interface to add the support he 
needed (e.g. to send demodulated audio back to the Mercury in this case) 
and chose to add the HPSDR support directly into the program, along with 
a specially modified WinUSB driver.

The problem is that then the source got forked multiple times, some who 
no longer share source (e.g. HDSDR), so the Ozy support is kind of 
locked in.

But I wonder if there isn't another way of doing this. Perhaps a new 
extio that understands the metis/hermes UDP protocol combined with using 
VAC would allow development of an extio that doesn't need support within 
the program itself.  The VAC part wouldn't be necessary if you were 
happy with using the computer sound for the audio output. But if you 
wanted the sound to go back to the Mercury/Hermes you could set Winrad 
to output to VAC and the extio would have an option to listen on the 
other side of the VAC and send that audio back to Mercury/Hermes via the 
network interface. Just a simple weekend project as Phil likes to say :).
