Ham radio is very cool. I am always surprised Bitcoiners are not more into it.

It would be very cool if Bitcoiners started joining & taking over ham radio clubs and started teaching old school hams about Bitcoin.

A great gateway would be making a club project of setting up a blockstream satellite node using the ham radio skills to get the signal from the satellite. So much crossover appeal. Bitcoin satellite nodes would also get young people excited to get into ham.

This would also make a great topic for someone who speaks at public Bitcoin events.
