Indeed Marcus, I ll give the script a go as a last resort, i m curious to find out what causing it. To troubleshoot it I upgraded the working one on 3.6.2 running on ubuntu 11.4 to 3.6.4.1, and guess what I m facing the same issue reported initialy , it looks like it is related to the gnuradio version !
