You don't have to have a license to attend, all are welcome. If you think you might be interested in ham radio, there are always technical talks covering various aspects of radio and its intersection with open source, as well as demonstrations of equipment. Someone typically makes a few contacts while parachuting near the venue!
(I expect someone will have an HF Signals sBitx HF (shortwave) transceiver there to show off. It's a mostly open source portable radio designed and built in India around a Raspberry Pi 4 that can communicate via voice, Morse code and various digital modes.)
