Re: Can Embedded Python Blocks have callbacks?

Hello, Can you post the rest of the code and a snapshot of your project in gnuradio? Because with only your function, it's hard to say what happens in your python block :) Best Regards M. Croizer Le mer. 19 juin 2024 à 14:52, Jameson Collins a écrit : > I'm trying to use a callback to set a

Re: Getting gnuradio to use zadig to connect to rtl-sdr in Windows

Hello again All, Got it working. I believe there is a deficiency in the soapysdr module that was prebuilt in mingw64 and I can now use the rtl-sdr with my gnuradio-osmocom package. Thanks, Chris On Thu, Jun 13, 2024 at 7:29 PM Chris Gorman wrote: > > Hello All, > > I have recently been playin

Re: Cleaning up a git repository

Thanks Marcus for the very useful information about git! Another piece of advice I would like to give to those who start with to git is to make sure not to store passwords, credentials, API keys, or other confidential information in git. While having 'build/' stored in git is an annoyance, ha

Re: GSOC FEC week 2 blog post

Hey Kayla, cool – good to read about you assessing when things don't go as quickly as planned. Just as a bit of reassurance: Setting up a toolchain and getting it to work with *two* medium-to-large C++ projects that are medium-to-old … that's a challenge! Please keep on it, and never hesitate

gr-hnch Pulse Sink / GNU Radio Audio ~ (was: Re: Audio sink to "wire")

Hey Henning, huh! Doesn't putting the same sink name into the upstream GNU Radio audio source do the same? Asking for a friend who's collecting bugs on the gr-audio blocks [1]… Best regards, Marcus [1] https://github.com/gnuradio/gnuradio/issues/2539#issuecomment-2078130433 On 06.06.24 22:08

Re: minor bug in control_loop.h

Hi Eugene, I believe there is this bug in other places (including other places in control_loop) too. Basically any time that an input float is used to compute an error which then ends up indexing some array (as could happen in a closed loop that indexes into filterbank), if the input is NaN,

Re: Audio sink to "wire"

Hi Jakub and Marcus: On the Mac, use the BlackHole virtual audio driver. It’s at https://github.com/ExistentialAudio/BlackHole. You can create a virtual audio device and point WSJT-X at it for input, output, or both. It works well and the developer is responsive to questions and suggestions.
