There's also the shortwave radiogram and other interesting stuff if you go deep. The portable receivers and straight up SDRs they sell these days are pretty amazing in terms of sheer availability. This receiver has been fun to use on the go: https://www.youtube.com/watch?v=j3WQQn7rM3k https://www.youtube.com/watch?v=j3WQQn7rM3k And the more consumer receiver stuff is now starting to ship with remote app control as well. A pretty awesome time for radio really.
