Radio repeaters are some of the best positioned decentralized communication points across the world.
The HAM radio demographic is an very aging population, however over time HAMs have claimed some of the most desirable territories in meat space for repeater locations and other natural geographic communication points (high ground with good line of sight). If bitcoiners were to join up to their local HAM circles, they could stand ready to inherit these decentralized communication points.
This is all the while being a good community member by making comms available during emergencies or natural disasters.
Learn the basics and fundamentals of the art of radio. Get involved in the local HAM community. Connect with other bitcoiners over the airwaves.
