When I was a kid I remember listening to shortwave radio on my grandfathers set. Back then there was a large variety of shortwave programming and I liked the radio drama shows mostly, but it was neat to listen to news from all over the world. Shortwave has shrunk considerably these days, and there aren't many stations left, but radio in general still is interesting and practical. I am using it mostly to gather information that would not be available otherwise, news from other countries and listening in on conversations about local events by amateur radio operators.
Just listening can be interesting and inexpensive. Having a shortwave capable set is a good idea for everyone, particularly to gather information in emergencies. The Tecsun models seem to be well reviewed as portable models and are powered by batteries. Eaton used to made a shortwave model that was solar and hand crank powered, but that appears to be out of production. If you get one, occasionally practice with it since finding something to listen to is different than regular AM/FM. Stations change frequency based on the time, so if you find a station you like it may have moved if you go back to it later. There are some US broadcasters, but most of the timeslots are filled with religious programming. You can find stations using sites like shortwaveschedule.com. The most interesting programming for me are the international broadcasts where I can hear news from other countries. With anything you read or hear, you will have to use discernment.
Amateur radio allows you to talk to others with a transmitter, sometimes over great distances. Getting a licence is fairly straightforward, the tests can be easily memorized since they are static multiple choice, but its a good idea to become familiar with the regulations and safety information. I normally don't talk alot, but i do enjoy is seeing what my station can do and what its reach is. In an emergency, I will be able to listen to information even if traditional communications is not functioning.
I use normal voice from time to time, but most of my time is spent in the various digital modes. A computer, I use a Raspberry Pi, makes tones and sends them through the radio, like text chatting. Another station can decode those tones to text and reply in the same way. Some modes are very efficient using low power while having greater reach then voice. My station is solar powered and my next focus is becoming portable. Backpacking isn't practical, but I am looking at some kind of cart or bicycle to transport the station, inspired by OH8STN, an off grid radio operator with a detailed Youtube channel.
Amateur and shortwave have less popularity than in years past given the Internet, but its practical applications in emergency communication remain relevant and in an emergency is to late to learn. For amateur operators, I would be interested in activities you enjoy on the air, and for those interested in starting in a radio hobby I would be happy to share what little I know. For those with a callsign, obviously do not share it here, since names/addresses are public record.
