[hpsdr] Software direction for openHPSDR...

[Ken N9VV]

Hi Dave, your contribution to ghpsdr3 on Windows is *OUTSTANDING*. Thank 
you from all 800 of the OpenHPSDR members :-)

Beginning in 2007, Phil Covington N8VB and Ms. Cathy Moss delivered a 
C++/Qt control program called SDRMAX and another called Panoptos for 
control of the QuickSilver QS1R DDC receiver. They were fully portable 
and would easily compile with MinGW/OpenGL/Qt on Windows and Linux. 
Their GUI was really cool. The use of OpenGL pushed the GUI load out to 
the video card and made the whole system very efficient for small CPU 
systems (mITX for example) and remote Internet users.  Panoptos is still 
carried on an SVN. I do not understand it's copyright or GPL status. 
N8VB later experimented with both the _Boost_ and _ICE_ libraries in a 
effort to improve the Internet remote control performance of the base 
program.  My QS1R was online for over a year and I logged listeners from 
42 countries.

I wanted to add that the John Melton server does indeed have CLI 
selections for steering the ADC Random and Dither. Here is part of the 
README from the trunk/src folder:
----------------------------------------
server - a server implemented using libusb 1.0 sync API.

     server
         --receivers [1..8]
         --samplerate [48000|96000|192000]
         --dither [off|on]  <------------------------
         --random [off|on]  <------------------------
         --preamp [off|on]  <------------------------
         --10mhzsource [atlas|penelope|mercury]
         --122.88mhzsource [penelope|mercury]
         --micsource [janus|penelope]
         --class [other|E]
--------------------------------------------

and from a Melton July 4th posting:
Here is his info for ghpsdr3:
----------------------------
ghpsdr by default sends the audio stream back to the server to be played 
out through Mercury.  There are command line options to use the local 
audio on the machine your are running on.

thank you for your seriously great port of the Melton code to Windows,
I do hope this discussion stimulates an expansion of the OpenHPSDR 
programming.

Beginning in Q1/2011 we may see several new DDC/DUC units for sale. One 
example is the tantalizing new "netSDR" from RFSpace 
(http://www.youtube.com/watch?v=q-Uh0hQK83A)

The pressure is increasing to have portable code for the OpenHPSDR 
hardware project if we want to remain an attractive experimental 
platform for the future.

thank you for reading my email,
