That is still via ham radio, and it's still very analog. A digital signal is created by a computer, which is converted into an [analog] audio signal, then piped through the [analog] audio input (either mic or line-in) of a ham radio, transmitted over [analog] RF, and decoded by the receiver's computer in reverse.
