Re: [Discuss-gnuradio] No module named wx
Similar situation down here in Brazil, but after adding the softlink it complains with file not found... or something similar... Any tips on where to put some break code to help debug the issue?

I'll chime in on the 'easy to intuit' requirements to get any of gr-* up, especially the gr-wxgui. Unfortunately other projects press and I have not been able to get a working 'graphical' user environment up, when most of the antecedent 'packages' don't seem to just build, and when they do the install seems not to place things in the 'right' places for building or using the gr-* codes sets.

Re: [Discuss-gnuradio] No module named wx
Fails at work on my SUSE 9.2 install and succeeds at home on my SUSE 9.2 install. Running python 2.3.4 at home and Python 2.4.1 at work. However, I just installed 2.4.1 at work. I got the same error messages before today with 2.3 first in the path. Having 2.4.1 first seems not to have helped (or hurt). The stuff you listed is in both the 2.3 and the 2.4 lib and local/lib python site-packages sub-dirs with the correct permissions. I get two errors: import wx says wx cannot be found and ./burn-basic-eeprpm -a says it cannot find usrp_prims even though both are clearly installed as in your list. This is a new error and just started.

In my limited experience with this stuff, DO NOT install multiple
versions of wxPython. Just have 2.5.

So I dig it out and take a look at the source code for the FSK ( fsk_rx.py) . I am a little surprised that there are no time recovery there. My understanding is that for fsk, if you use noncoherent demodulation, you would not need the phase information. However, you still need to know the timing in order to correctly sampling the output of correlator or matched filter. Could you give a hint of what is going on here ? david The output rate of gr.quadrature_demod_cf is 8 times the symbol rate. The selection of the center of the bit is done in gr.simple_correlator. It watches for a pseudo random sync pattern at the beginning of each packet and uses this to figure out which of the possible alignments is best. A similar technique is used in Bluetooth.
