[hpsdr] ghpsdr3 servers on Windows--progress

[David McQuate]

I'm attempting to port John Melton's ghpsdr3 server and dspserver to a 
Windows environment, with partial success.
I'm making minimal changes to his code, staying in C, using Visual Studio 6.

I'm using windows versions of DttSP, fttw, and pthreads, and Ozy-init 
code from USRP-hpsdr.
Things that seem to work--
  loading Ozy Fx2 & fpga
  commands (attach and start) from dspserver to server
  commands from jmonitor to dspserver (e.g. frequency / band / mode change)

Things that don't work yet--
  no receive audio
  no spectrum or waterfall display.  jmonitor just writes full-width 
white lines, seemingly at random, for the waterfall display.  The UDP 
ports used by server, dspserver, and jmonitor seem to be consistent.

The above results were with Ozy software version 17, Mercury 29, and 
Penelope 12.

If I reprogram Mercury with the multi-Rx code from W1BW, the 5v power 
supply current is increased from the "normal" value, my little power 
supply goes into current limiting (> 1.2 amp, with only Mercury & Ozy on 
Atlas), and the server calls to OzyBulkRead() fail with code -22.  This 
may be due to low power supply voltage, or to software / firmware 
incompatibility, I don't know which, at the moment.

Has anyone else noticed increased Mercury power supply current when 
using the W1BW code?
If it's "normal", I'll use a more capable power supply and continue 
toward a working multiple-receiver system.
