  • aHPSDR (opengl branch). This version uses opengl for waterfall display. Experimental. Right now hardcoded for 720p portrait orientation (on my Samsung Galaxy Nexus) and so will not display correctly in other devices as it is actually a 3D display. Will implement it in Ortho2D in future version to automatically fit other devices.

  • New build of aHPSDR (opengl branch). Will only work with protocol-3 capable dspservers. This has improved spectrum/waterfall refresh rate. Work-in-progress in adding opengl code for waterfall display. May not work in older Android platforms.

  • The branch audio-testing was created for linux users who were having trouble with Qt's lack of sound in QtRadio. It seemed to be more of a problem with newer 64 bit installs. audio-testing bypasses QT for audio playback and calls pulse audio libs directly. You may have to direct sound to your proper sound device with pavucontrol.

  • Created an article on the Utilities & Add-ons page called: "Full featured recording script" unsing sox and rigctl (hamlib).

  • A new branch, opengl, has working QtRadio code that uses OpenGL shaders to compute and display the waterfall. The waterfall is actually a 3-D cube and you can pan/zoom with mouse drags on the waterfall display. Drag it all the way to one side and you can have a glimpse of the sides of the cube. The aim of this QtRadio is to offload work from the cpu to the gpu. If your system has a weak cpu (eg atom) and a powerful gpu (eg nvidia ION) it should reduce the cpu util significantly.

  • A new build for windows from the new protocol-3 branch is available at: http://napan.com/ve9gj/qtradio-protocol-3.zip (Built Mar 18 2012). This uses the new protocol-3 and should be able to connect with master and protocol-3 servers. Still experimental. It contains improvements to the spectrum and waterfall refresh rates for remote connections.

  • Graeme ZL2APV has coded CW receive in QtRadio to behave the same as Kenwood, Yaesu, K3 etc.

  • Bugfix to possible segfault in dspserver

  • The android client AHPSDR now has a Server list feature just like QtRadio. Look under the menu item Servers and select from among the active servers Download information on the AHPSDR page
  • The branch to use for most users is now the master branch. This is the one that most dspservers are running
  • Fixed SetTXAMCarrierLevel bug when tx ="all" in master branch
  • Two key Rx audio functions into their own QThread in QtRadio. This should help lower spec'd PCs
  • Fixed a bug where the band edge line in the spectrum display was off by the offset value of the dspserver.
