[hpsdr] Thanks Kirk!

[Phil Harman]

Hi Roland,

I am able to find a difference between Kordic and cordic.  The former has some 22 spurs between 0-55MHz that are not present with cordic. I've let Kirk know this and he is going to modify Kordic to include the innovations that Cathy Moss provided. 

I started working on Phoenix again this weekend.  The project leader, Richard, VK6BRO has now established himself in VK8 and we had a few interesting 'phone calls as we set up his PC to run the various items of software. I hope that by now Richard has a working system.

The latest Phoenix files are under SVN here

< svn://206.216.146.154/svn/repos_sdr_hpsdr/trunk/Phoenix >

The current Alpha Phoenix boards do work. In conjunction with PowerSDR if forms a complete QSD/QSE transceiver. However, there is one major issue, the level of spurs from the AD9912 are horrific!.  Since others use this device successfully I hope that its a simple fix.  

Work on Mercury and other projects has kept me away from Phoenix but with Richard now on board again I hope we can progress it further. 

73's Phil...VK6APH

  Hi all,

   

  I want to say thank you to Kirk for his very nice job on explaining Verilog's code for the hpsdr boards! I have learn a lot!

  Right now, I am running the test code on Mercury, Penelope and Ozy, receiving and transmitting with no problem, I cannot see any difference between Kordic and cordic on Mercury.

  These boards are now my main equipment, followed by a TS50's amplifier and filters, with a home made broadband hexbeam antenna, I enjoy dxing in ssb!

  What are the news from Phoenix, I have a Janus and Ozy boards waiting her to play.. 

   

  73, Roland f8chk.
