vCOM Build 224 released

Build 224 of the vCOM virtual serial port driver is released.

There were two reports by two different people that vCOM build 222 would hand their system. Not BSOD, but just freeze. I have adjusted the thread priorities in build 224 out of the real-time range where they were set in build 222. I think that perodically the threads priority would be boosted above the GUI's thread priority causing a deadlock.

Important: You will need to edit the N8VBvCOM.inf file to match your current inf file before updating the driver. Once you have the inf edited you can run the update.bat file to update the driver.

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.
