-The normal ghpsdr3-alex package needs QtSDK installed as well a lot of graphic specific librarys. At present, this is beyond the scope of this How-To, and it will be left for another day to produce the GUI part of this, ie. QtRadio. The PandaBoard will only be running the minimal code necessary to have a functional SDR server radio. pulseaudio and portaudio are required for non hpsdr protocol servers, and have been built successfully, however at present they are not used for the widget-server and could be eliminated from the build.
+A good introductory guide to ghpsdr & ghpsdr-alex is available:
 This code is built outside of buildroot, but using the buildroot created toolchain. This is done by adding a Makefile to dspserver, DttSP, and widget server. The Makefile has a hardcoded path to the toolchain, so it may (will) be necessary to alter it to fit individual circumstances.
