Re: Problem with my python block for WSPR coding Process
Hello,
I worked on it, and I correct things in my python block and my grc file. It
works when I put QT GUI Time Sink blocks, than Histogramms block. You can
fin the update here :

Announcing GRCon24 !!
Greetings GNU Radio Community! We are excited to announce that the GNU Radio Conference 2024 (GRCon24) will be held on September 16-20 at the Knoxville Convention Center in Knoxville, Tennessee, USA. Please Save-the-Date! Attendee registration for the event is already open. More details about the event for attendees, participants, and sponsors are available on the event website. https://www.gnuradio.org/grcon/ https://events.gnuradio.org/event/24/ The Call for Participation (CfP) opens today (Friday March 1). Submissions for papers, posters, talks, workshops, and other contributions are now being accepted through the GRCon24 website. The Call for Participation will close on Monday June 17. https://events.gnuradio.org/event/24/abstracts/ If you have any questions about attending and/or participating, or if you would like to find out more about becoming one of our valued sponsors, then please contact us here on the mailing list, or via email at gr...@gnuradio.org, or via our Matrix chat server at https://chat.gnuradio.org/. Note that this event can only be successful because of our sponsors. The link below contains more information about sponsorship opportunities. https://events.gnuradio.org/event/24/page/158-sponsorship-opportunities Since GRCon is run by a group of volunteers, we are also looking for people to help with both the planning of the event and assisting during the event. If you are interested in volunteering in any capacity, please see the link below, or please reach out to us at gr...@gnuradio.org. https://events.gnuradio.org/event/24/page/159-volunteer-opportunities We look forward to seeing you at GRCon24 !! Sincerely, The GRCon24 Organizers
Re: Faq? GRC and gnuradio versions don't match?
Thank you! I followed your steps, now I have 3.10.9.2 working! dcherkus@dmin:~$ gnuradio-companion *grc<<< Welcome to GNU Radio Companion 3.10.9.2 >>> I made myself a note to do 'make uninstall' before trying a new version. Regards,Dave
Re: Faq? GRC and gnuradio versions don't match?
Hi Dave,
nope, not the way it should be. You should have uninstalled your GNU Radio
3.10.6.0 first!
Anyways, what is happening now is that Python loads the Python GRC module in version
3.10.6.0, but your GNU Radio binaries (and also probably your libraries) are loaded in
version 3.10.9.2.
That's going to fail. Please uninstall your 3.10.9.2 (go to the build/ directory, `sudo
make uninstall`) first, then check /usr/local for all things that might be remainders of
your now dysfunctional 3.10.6.0 installation, and remove them. Especially
/usr/local/lib*/python*/{site,dist}-packages/gnuradio* will contain outdated stuff.
Afterwards, do a clean build (meaning: remove everything from build/, and run `cmake`
again, run make, run make install).
Best regards,
Marcus
