Yeah it's called the weather broadcast, it's one way. 😂

There should be an app to use the soundcard as the modem for weather maps, there are for other modes.

This just gave me an idea: of creating a website where you can log in with nostr and create notes based on reports from IOT devices that measure weather in your area and make it public knowledge.

It doesn’t predict whether unless there is some AI that could use the current data and forecast from it.

What do you mean by “privacy focused”?

Found the one for weather maps, HF Weather Fax.

Breezy

You may also possibly find some apps for satellite using a rtl-sdr dongle, but that won't be much good for finding overseas weather, just your region.
