Hi, Last year when i discovered gnuradio i did some tutorials of the wiki. The documentation were great, but it was outdated. I really found disgusting to use a deprecated module (Qt Gui sink) in the tutorial. To sum up, I think that the wiki needs to be upgraded to 3.8.0.0. I appreciate your

Hi Bogdan, I'm afraid that's a bit out of the realm of what César can do – that's gnu.org infrastructure, and we're still (still) trying to figure out whether (and if so, how) it's possible to repair. Cheers, Marcus On Sun, 2019-11-17 at 17:53 +0200, Bogdan Diaconescu wrote: > You may start fixi

You are _NOT_ an idiot. There were serious bugs in the generic implementation of several of the type conversion kernels. Best regards, Marcus On Sun, 2019-11-17 at 12:20 -0500, Marcus D Leech wrote: > Thanks Ron. > > I did some more testing, and it appears to indicate that I’m an > idiot. I won

Thanks Ron. I did some more testing, and it appears to indicate that I’m an idiot. I won’t go into the sordid details. Sent from my iPhone > On Nov 17, 2019, at 6:17 AM, Ron Economos wrote: > > It's pretty easy to test for Volk issues. Just edit the ~/.volk/volk_config > file and change

Hi Cesar, I'm another of the project leads (Marcus and Martin both are as well) and I can promise you that we won't find you annoying! If you have questions about the tutorial then they need to be improved and we'll happily help as we can. (Spoilers, they need improvement!) Thanks for taking a loo

Christophe, See my message to Andy, I managed to get this working by using the 'PLL Ref Out' block which does produce a nice 19 KHz tone. Then filter (BFP) and multiply by three using a 3-input multiply block, to get a 57 KHz reference signal. Next, use a complex conjugate to turn negate t

It's pretty easy to test for Volk issues. Just edit the ~/.volk/volk_config file and change the volk_32f_s32f_convert_16i line to generic for both alignments. On my older box, volk_config has u_avx for both alignments (and that works correctly). Ron On 11/16/19 17:55, Marcus D. Leech wrote:
