[hpsdr] Win7-64 usage

[Steve Bunch]

I had no trouble with the Mac version of HPSDRProgrammer after fixing the 
problem I reported earlier, and updated Metis/Mercury/Penny to the firmware 
versions from the openhpsdr download site.

I then downloaded PowerSDR 1.9.3 from the Downloads link at openhpsdr, and 
installed it on Windows 7 Professional 64 bit, running in a virtual machine 
under Parallels on a MacBook Pro running MacOS 10.6.6.  PowerSDR did not work, 
reporting an error with JanusAudio that sounded familiar.  I searched the 
openhpsdr mail history for JanusAudio, and found previous emails that described 
the problem I was having and how to fix it.  The workaround was to remove Metis 
and install Ozy, download the appropriate driver from the Flex Radio site, and 
run PowerSDR once with Ozy, then, turn it all off and disconnect it, remove Ozy, 

put in Metis, start PowerSDR and switch to Metis (see the earlier emails for 
details).  It was a pain, but it worked and PowerSDR became happy.  I don't know 

if there's a way to do it that doesn't require an Ozy.

Running PowerSDR on Win 7 on this VM results in CPU usage 3-4x higher than 
Heterodyne (native Mac) running on the same MacBook (70-80% vs. 20% of one CPU). 

Dropouts are rare.  The latest version of Jeremy's Heterodyne program runs 
well.  I downloaded and briefly tested KK on the Windows 7 virtual machine, and 
it appears to run fine.

If anyone has questions about any of this, feel free to contact me offlist.

Using this setup, I was able to give a demo of Metis/Mercury/Penelope, running 
PowerSDR on Windows 7 on a Virtual machine running on MacOS X on a MacBook, 
using a USB display adapter dongle to drive the projector, to accompany my SDR 
talk at the Motorola Amateur Radio Club meeting last Tuesday.  Despite the fact 
that the level of interference at the restaurant was incredibly high (neon signs 

and other broadband interference sources), we were able to pick up a few strong 
signals to play with, and there was a lot of interest.  Thanks to all the HPSDR 
contributors!

G'day,

FYI, here are the results of my testing:

Neither PowerSDR 1.6.3, PowerSDR 1.9.3, PowerSDR 1.9.3 Diversity and  
Kiss_Konsole_Ethernet work on Windows7 64bit, but perform well on WinXP 32bit. 
I was able to use HPSDRProgrammer to upgrade Metis to V1.1, but failed to 
program Mercury with V6.4 (erase time-out).

GHPSDR3  with Metis has problems running on Ubuntu 10.04LTS (QUAD CPU). Strong 
signals >-60dBm within the sample bandwidth will cause the noise floor to 
raise by >20dB and distort signals of weaker stations. I can't remember seeing 
this with the old GHPSDR connected to OZY. Will re-check to confirm this.

73, Berndt
