Check out “slow scan tv” if you haven’t already. I have my amateur license and was surprised to learn all of the ways in which radio waves can be utilized

The International Space Station was transmitting slow scan TV pictures last week. You can receive them with a handheld radio and the stock antenna on the high elevation passes, but a handheld yagi antenna works much better.

I first learned about SSTV over a decade ago from Portal! I remember I had to get a two sided 3.5mm audio cable to plug my computer’s speaker. https://youtu.be/DlIvnc-AZJQ (Video of someone decoding it.)

No worries! I think this was before Portal 2 and meant as a teaser. The person in the vid clearly has an interesting setup but you could do it with just a normal PC very easily.
