Re: [Discuss-gnuradio] maximum recursion depth exceeded
Also, what version of GNU Radio are you using? (I seem to remember we made a change that produced a more informative message in this case.) Eric Thank you so much for the reply. 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.

Just informing the group that, from what it seems, the default python version for Ubuntu 9.04 will be the same it was for 8.10, namely 2.5.2: http://packages.ubuntu.com/jaunty/python Instead, python3 is included in both 8.10 and 9.04. Is the plan to port gnuradio to python3?
