vSound Progress & HPSDR OZY

vSOUND

I thought I'd better post an update to my progress on the vSound virtual sound card driver. I have been looking at the WDF stuff from Microsoft and how it could be supported in the upcoming Vista. There are some considerable issues in writing sound drivers that will work in Vista with the Digital Rights Management (DRM) crap. I am hoping to write the driver so it will work in W2K, XP, and Vista.

I would very much like for the driver to work like jack does in Linux. Some things are not possible in Windows, but I think I can get close to jack's functionality.

I hope to have something together to test in a month or so.

HPSDR OZY

I posted a photo of a almost complete OZY board on the HPSDR Wiki. Testing is going well. See updated info at hpsdr.org

History of HPSDR Mercury and Quick Silver

History of HPSDR Mercury and Quick Silver Philip Covington, N8VB Early HPSDR and XYLO In 2005 I started a High Performance SDR (HPSDR) project which was to consist of a motherboard carrying a FPGA/USB 2.0 interface and power supply with the provision for plug in modules through 40 pin headers. I had planned a narrow band high dynamic range module based on a QSD/DDS/PCM4202 audio ADC and a wide bandwidth module based on a high speed 16 bit ADC: http://www.philcovington.com/SDR/PICS/HPSDR_FPGA_USB_Board_top1_800600.jpg http://www.philcovington.com/SDR/PICS/HPSDR_FPGA_USB_Board_top4.jpg I soon selected the LTC2208 ADC from Linear Technology. A representative from Linear Technology came across my blog ( http://pcovington.blogspot.com/ ) and offered evaluation boards and samples to support the project. At about the same time my HPSDR project came about, Phil Harman, VK6APH and Bill Tracey, KD5TFD were interested developing a sound card replacement to be used with the SD...

Rumors and other nonsense...

[07.25.2012] Recently I have seen this subject brought up again when it should have been put to rest a long time ago. There was a talented volunteer software developer (Cathy Moss of the UK) who developed a GUI software application for the QS1R (called Panoptos or SDRMAX III) who eventually stopped developing the software. There has been much speculation on why she left the project. These recent references to Cathy Moss, who volunteered to write a GUI that worked with my QS1R server, demonstrates how ridiculous fabrications, gossip, and rumors can become.
