Re: [Discuss-gnuradio] missing python package
NOTE: My previous comment about WX not working properly applied to Python 2.5, not Python 2.4. Apparently the latter searches subdirectories while the former does not. Thus the need to link in subdirector(ies) into the actual PYTHONPATH. After getting the necessary background stuff installed, GRC works OK using a standard MacPorts python 2.4 install. I am running: Intel iMac 20", OSX 10.4.11, latest GNU Radio SVN trunk, latest GRC SVN trunk. Things to check: * 'port installed' returns include (for GRC; dependencies will also be installed; make sure these are 'active' and if not then 'activate' them): py-gtk2 @2.10.4_0 (active) py-xml @0.8.4_0 (active) * 'cd /opt/local_2.4/lib/python2.4/site-packages ; ls' contains (at least): _xmlplus/ cairo/ gtk-2.0/ numpy/ pygtk.pth pygtk.py pygtk.pyc pygtk.pyo wx-2.8-mac-unicode/ wx.pth wxaddons/ wxversion.py wxversion.pyc * 'printenv' contains the following (or more, but at least these): PATH=/opt/local/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/ X11R6/bin PYTHONPATH=/opt/local/lib/python2.4/site-packages:/usr/local/lib/ python2.4/site-packages ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio

Re: [Discuss-gnuradio] missing python package
I just tried using py25-gtk2 (2.12.0; my personal install with a Python 2.5 framework, which is also a personal install), and it works just fine. I'm moving back to Python 2.4 (not my personal install, just MacPorts) to test that out, and will report back when I know more ... I didn't have py-gtk2 installed, and that has a whole bunch of dependencies that need to be installed first, etc... On a side note related to MacPorts and Python, some of the py- modules aren't installed correctly any longer; some never were (who's doing QA here!). py-gtk2 might be one of them. As e.g.: wx-python 2.8 doesn't create the correct directory structure to do "import wx" ... links are needed to do this correctly (and aren't part of the standard Portfile; corrections have been submitted for this particular bug). ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio

Chuck has put up a new webpage at http://www.swigerco.com/ The GnuRadio stuff is under http://www.swigerco.com/gnuradio/index.html But I can't find the PSK31 stuff. On his old page it was at: http://webpages.charter.net/cswiger/psk_experiment.html (I am very happy though that his GnuRadio vector analyzer info is back online) I have successfully decoded PSK31 in the past using the following. Capture using Gnuradio to file. convert the file to a wav file using sox decode the file using some other opensource PSK31 program. You can do all this in realtime if you use Pipes in stead of files. in pseudocode it would look something like this: mkfifo psk.raw mkfifo psk.wav usrp_rx_cfile.py [commandline options here] -s psk.raw sox [commandline options here] psk.raw -o psk.wav pskprogram psk.wav It's a while ago, so I don't remember all settings I used. I think I captured to file in the short format (not in the float format) Of course, much better is to implement PSK31 in the gnuradio framework.

Yes Lars, I'm sure you are correct, it's something to do with our version of Python. When I downloaded and installed a required package 'wxWidgets (wx-common)' and 'wxPython (python-wxgtx2.6)' I had a message to say wx- was previously named 'wxWindows'. Guess what?

[Discuss-gnuradio] USRP timestamps
Hello! I´ve got a code to write and need some help. I´ve got gnuradio installed and the USRP up and running. I need to write some python code that does the following: - it captures wlan traffic and tells me at which time a packet arrived and at which time the transmission of this packet ended. I do not need to decode the packet and neither do I need to know what kind of packet that was, just the "timestamps" and the duration. So can anybody give me a hint or maybe a link with some material on how to do that? I already successfully can run the usrp_fft.py and I can see that the USRP is working fine and I can see the device receiving signals if I set it to the correct frequency, so I know that it works, I just need a simple code that gives me an output of timestamps.

The sample rate of the ADC is 64Msps. The samples then go through the CORDIC to generate complex pairs, then through a CIC with minimum decimation of 4, and then through a halfband 2:1 decimating filter. What symbol rate are you looking at in your simulation and how many samples per symbol are you looking to process? What are the characteristics of your filter (taps, symmetric, etc?) The lack of hardware multipliers inside the FPGA requires you to run a relatively simple filter unless you are running at "low" sample rates which allows you to serialize the data going through one or two multipliers and accumulate the output.
