blinry22: Receive maritime weather reports
The German Weather Service broadcasts maritime information throughout the day on various shortwave frequencies.
They use a protocol called RTTY (radioteletype), and it took me a while how to decode it. But I found a neat little program called "fldigi": You can pipe audio to it, and then if you pick the correct settings, it happily transcribes the messages!
Here's the station weather reports for the Baltic Sea and Northern Sea!
