[Discuss-gnuradio] GMSK Demodulator -- Assertion 'imu=0 failed.
Hi , I was running a GMSK demodulator to demodulate a file source signal, and I have come up with the following error. I think there is a data type problem associated. Does anybody have similar problem ? I check the previous posts but there is no answer on that. Here is the code : [EMAIL PROTECTED]:~$python demod_file.py gr_fir_fff: using SSE python: gri_mmse_fir_interpolator.cc:66: float gri_mmse_fir_interpolator::interpolate(const float*, float) const: Assertion `imu = 0' failed.

[Discuss-gnuradio] problem with wx
Hello everyone, I've installed gnuradio 3.1.1 on a system running slackware linux. Im new to linux and my knowledge on linux is rather limited. Inspite of this, I've somehow managed to install the packages correctly and have also successfully tested it by running the dialtone example and a few others. However, Im facing problems everytime i try to run a program involving wxPython. For example, when i run the hfx2.py, i get the following output, Traceback (most recent call last): File ./hfx2.py, line 81, in ? import os, wx, sys, math ImportError: No module named wx Could someone please tell me whats wrong? Any help will be greatly appreciated. Thankyou. - Be a better friend, newshound, and know-it-all with Yahoo! Mobile.

[Discuss-gnuradio] RFX900 Transmit Power
Hello again, I have another question regarding the RFX900 daughterboard. I am trying to get a sense of the power transmitted by the RFX900 board in order to avoid breaching European communication regulations. Ideally a figure for the equivalent isotropically radiated power (EIRP) would be great. Will the power output be different with and without the SAW filter? Cheers, Tomas O'Maille PS. Thanks for taking the time to look at my increasing number of posts. -- View this message in context: http://www.nabble.com/RFX900-Transmit-Power-tp15270526p15270526.html Sent from the GnuRadio mailing list archive at Nabble.com. ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio

[Discuss-gnuradio] tunnel.py and PS3
Hello all, tunnel.py (examples/python/digital) hardcodes a value TUNSETIFF = 0x400454ca This does not seem to be compatible with the PS3. running tunnel.py returns ifs = ioctl(tun, TUNSETIFF, struct.pack(16sH, gr%d, mode)) IOError: [Errno 22] Invalid argument Changing the hardcoded value to TUNSETIFF = 0x800454ca (changed 4004 to 8004) allows tunnel.py to function properly on PS3. Question: Anyone have a good way to set these values other than hard coding them? i.e. how can we get the values directly out of linux/if_tun.h?

E.g., int get_TUNSETIFF() { #ifdef TUNSETIFF return TUNSETIFF; #else return -1; #endif } Feel free to drop it into gnuradio-core/src/lib/general and send a patch.

[Discuss-gnuradio] kludge_copy question
Hi, I have a class that inherits from gr.kludge_copy. For now this class does nothing but to copy the inputs to outputs: class MyClass (gr.kludge_copy): def __init__(self, size): gr.kludge_copy.__init__(size) I might not have done something correctly so when I used MyClass as one of the blocks in my flow graph, the error was: TypeError: Error when calling the metaclass bases function() argument 1 must be code, not str I looked at the kludge_copy QA code. It's used as a standalone not an inherited object. So am I using it correctly in MyClass?
