Hello, There was some interest on this list earlier about the Beagleboard, a small OMAP3 based board. I just got one from Digi-key and it is small! http://beagleboard.org/ Besides the GNURadio aspects this may be a good board for ham radio digital modem applications like the old TI DSP Evaluat

[Discuss-gnuradio] Cannot Run TX Flowgraph More Than One time

2008-08-01 Thread Firas A.
Hi, I thing there is a bug (defect) in gnuradio core. Checked with svn revisions 7311 and 9036, on CoreDue system with Ubuntu 8.04, and USRP + RFX900, it seems that we cannot run TX flow graph properly more than one time. If we started it more than one time, we will have a very distorted TX sig
