25 soon to be 26, my family liked to camp out in the Mojave when I was a kid so I do know how to use them but even for me I am far more familiar with stereos .

I still know the kind you tune with a slider on a coil. Same age.

Sure, in a technical sense, that’s true - the car radio in our 2025 Hyundai i10 is a DAB+ radio, which supposedly still has backup FM capability. Which is never used, as you just pick the station from a list. It’s never used anyway - I much prefer podcasts.

WiFi is of course radio. We just tune in and listen to it differently.

If you limited your bandwidth to 20 or 30 kHz, you could build a “radio” that you manually tune to a WiFi channel frequency and that produces audible noise. You could then build a 1980’s style modem to convert the audio back into a bitstream that you could run your network connection over.

It would be about many times slower than standard Wifi though modern compression could speed that up a bit.
