It used to be a programm called rtl_fm. Check it if you are convenient with terminal.
I have an rtl sdr, a raspberry pi zero and an esp32 module. Can i turn this stuff into something like a flipper or a hackrf sonehow?

Also there is another cli program called predict that tracks satellites. So maybe you could use that to receive weather images...
