Greetings all! Special thanks to Jean-Michel Friedt for submitting the first Block Party article for QEX Magazine.
If you are thinking about submitting an article for this series, then please get in touch and I will do all I can to make the job easier. -Michelle W5NYV On Wed, Jun 30, 2021 at 4:27 PM Michelle Thompson < mountain.miche...@gmail.com> wrote: > Call for Submissions: GNU Radio "Block Party" Articles for ARRL QEX > Magazine > > You are invited to contribute an article for ARRL QEX Magazine.
