Hey Zaky,
great to have you here! I saw you on chat, and it's really going to be fun learning with
you! This is a really good time to work on standalone GRC; I'm sure you can always reach
out to the community and we'll be very interested in helping you!
Best,
Marcus

Hi Ivan,
excellent investigation. I must admit that I don't know what could've gone wrong there,

Hi Jim,

Greetings everyone,

necessary changes: yes, a few things will need to be updated to GNU
Radio 3.10, but that's mostly syntax, not functionality. If you want to
