You might know about this already but it's weather related so I'll post it here. You can use a shortwave radio and some software to download weather charts over RadioFax:

Not sure how much it's still used in the age of satellite internet but it's for ships to get charts when they're in the middle of the ocean.
Good digging.
I'm a little bit deeper into the hole I think. I've got a scanner on my desk and listen to ATC all day while I work :D
I think this is the first time I have admitted this. I also use my scanner to intercept voice and video signals from the ISS when it passes over.
I probably need help.
