News:

09-15-2009 The backlog in production of the QS1R Receivers is starting to clear.  We normally quote that QS1Rs ship 3-5 business days after order.  Our backlog has extended that to 14 business days since the August 2009 shutdown.  We should be back to 3-5 business days by the end of September.

05-07-2009 QS1R Information and Ordering For more information about the QS1R please consider joining the QS1R Yahoo support group:  http://groups.yahoo.com/group/qs1r/ QS Transceiver System Info

08-21-2008 Please join the QS1R Yahoo support group:  http://groups.yahoo.com/group/qs1r/ QS1R gets dual receive capability. FMW mode is implemented.

01-30-2008 QS1R Webpage is up: http://www.philcovington.com/QuickSilver/ Orders for the first group of QS1Rs from assembly will be taken very soon.  Please keep checking the website. See the latest news at: http://groups.yahoo.com/group/qs1r/ Here is a picture of a production QS1R RevC board: 01-10-2008 QS1R Ready for production: QS1R Yahoo Support forum: http://groups.yahoo.com/group/qs1r/ See my blog for more info...  http://pcovington.blogspot.com/ Below is a Rev B board, Rev C has some cosmetic clean ups and the addition of a SD card for configuration.

10-17-2006 OZY FPGA_USB Board Update: Here is a photo of the OZY alpha REVA board: See the HPSDR Wiki for more information on OZY. OZY FPGA_USB Board: The preliminary schematic for the OZY board has been posted to the hamsdr.com website and to the hpsdr.org SVN server. <http://www.hamsdr.com/personaldirectory.aspx?id=231> The HPSDR group SVN URL is: <svn://206.216.146.154/svn/repos_sdr_hpsdr/>

03-13-2006 New domain and website: The HPSDR and XYLO SDR groups have merged.  We now have have out own domain, website, and mailing list - hpsdr.org To join the mailing list go to the hpsdr.org website and sign up. Atlas Bus proposed physical design: I've posted a proposed physical design document for the Atlas bus/backplane. <http://www.philcovington.com/HPSDR/ATLAS/Atlas_doc.pdf> Other files can be seen at: <http://www.philcovington.com/HPSDR/ATLAS/>

02-18-2006 HPSDR Progress Report: The HPSDR ADC board is now code named "Mercury".  It will use the Linear Technology LTC2208 130 MSPS ADC.  I have begun the PCB design for the Mercury board. SMT Soldering Info: A cool discussion of techniques - Here

12-09-2005 HPSDR Progress Report: I am now able to configure the Spartan 3 FPGA over USB.  I switched from slave parallel mode to slave serial configuration loading.  This will make the FX2 firmware easy to use with Altera Cyclone FPGAs in addition the the Xilinx Spartan 3.   I am in the process of getting samples of Linear Technology's LTC2208 16 bit, 135 MSPS ADC.  I still plan to develop a QSD based RX board using the TI PCM4202 as the ADC -  So there will be a high bandwidth path as well as a low bandwidth path in the HPSDR.  The LTC2208 board will probably get it's own FPGA to do DDC.  The DDC's ouput will then feed the Spartan 3 which will be responsible for performing the  second part of the DSP chain. Verilog Projects for the Xylo Board: I set up a folder on my server that people can browse .  It will contain various verilog projects that can be tried on the Xylo board for educational purposes. http://www.philcovington.com/FPGA/

10-14-2005 Calibration Notes for the SR40 using the SharpDSP Mini Console

10-12-2005 Latest update is version: 1.0.2111.27139 on 10/12/2005 Just released - SharpDSP Mini Console for the SoftRock 40 - Download it Here  This is a pre-Alpha release so expect some bugs.  This preliminary release supports: Sample rates up to 96000 Hz Selectable block sizes from 64 to 8192 Settings are saved in a text editable XML file (softrock.config.xml) Center frequency can be set for other bands besides 40 meters. Very low resource requirements (should help on older machines)  Future updates will include the following features: Dual receive capability within the Rx passband Analog S-meter Panadapter Display TCP CAT support Serial CAT support TCP Audio Server support Much more...
