Not a ham myself, but my father is. With that context, as far as I understand: * Minimum equipment necessary is as simple as a walkie talkie, though if you want to have an actual "radio station" per se you need an antenna and a transceiver and the wiring to hook it all up. Note that a ham license concerns transmitting radio signals, if all you want to do is just receive ham radio signals you don't need a license. * Ham radio exists for anything that falls under communications. Communications during an emergency is an oft cited use case, but if you just want to talk shit with your ham friend across the continent or even the world one random Tuesday evening that's perfectly fine too. * The fun aspects of ham radio lie in the electrical engineering aspect and the communication aspect. You need to have proper understanding of all things electricity to fully understand and appreciate what goes into transmitting radio waves, and that might be something you find fun. If you find the idea of talking to someone just because you can fun, that's also something ham radio can satisfy.
