Software Systems Consulting advertised this system on Sky & Telescope around 1993. This was a software/hardware package which captures data broadcast on shortwave radio i.e. satellite images weather maps, etc. You can then display the images on your PC. You need to have your own SSB receiver.
They also did a product called PC SWL 3.0 which is similar.
If you have either of these systems lying around and no longer used, then I would like to hear from you.
