#hamradio RC3 SDR Capture The Flag has started:
https://sdrcts.tildepipe.org/

For people interested in #sdr and #dsp
A very nice entry-level #ctf (Capture the Flag/Capture the signal) for everybody learning #gnuradio. It runs from today to the 30th.
A CTF is a nice way to learn about radio-signals and radio-technology outside the usual hamradio sphere.

If you are new to CTFs and have never doen this, we can could set up a small team and do this together to get your feed wet! Just reply!
