Back in my shortwave days, we would do this with regular short wave radios and whatever home computer you had — Commodore 64, Apple ][, etc... Much simpler, and cheaper.

I think the service was called WEFAX, but my memory is a little hazy. It was used to send weather maps and satellite photos to ships at sea.

Does this still exist on shortwave, or is it all on satellite now?




It's still very much alive on shortwave. Here's a US ham demoing it: https://youtu.be/ZB1Fz294aLw
