I'm using GNU Radio 3.2 svn. I've another question related to the received data. I'm trying to capture the signal just after tunning back to baseband by using file_sink_c(gr.sizeof_gr_complex,filename) and reading data in octave. Here is a portion of the data I captured: 0 -2i 6 +9i -33 - 52i 83 + 144i -189 - 331i 368 + 663i -694 - 1258i 1365 + 2435i -4062 - 6523i 1164 - 1570i -1669 + 550i -1177 - 2948i 605 + 1495i -320 - 797i 159 + 403i -70 - 186i 25 + 70i -6 - 18i 0 +0i 0 +0i 0 -1i 0 +0i 0 -1i 0 -1i 0 +0i 0 -1i 0 +0i -1 +0i 0 +0i -1 +0i 0 +0i 0 +0i -1 +0i 0 +0i 0 +0i 0 +0i 0 +0i -1 +0i 0 +0i -1 -1i I got an info on dealing with the received data, the firest 20 or so samples is an artifact of the USRP due to the first time enable, which can be ignored. However, How can I figure out how many samples can be ignored in my case? Where can be starting sample to collect the data to do analysis? Thanks for help.

I want the python 2.6 issue sorted out before the final release of 3.2. Johnathan has recently made an rc0 tarball that I suspect he'll announce real soon now. If anybody wants to dive in and sort this out, it would be most appreciated. Reading the python docs that explain what's changed between 2.5 and 2.6 would probably be a good start.

I'm working out a way to get libtool to do the linking on the build machine and then running "make check" on the beagle.

Hi All, i built gnuradio companion via svn. My current System is openSuse 11.1.
