    The other day I got a press release about disaster preparedness for grade school kids.

    It made mention of teaching kids how to use a battery powered radio to get information. And it suddenly struck me that my 8 year old nephew likely has never even SEEN an FM radio, much less would know how to tune one to a specific station.

    Shit like that makes me feel reaaaaaaallllly old…

      My elderly father was confused when he bought an old style fm radio and found out it was only a Bluetooth speaker.

      I’m in my 30s and really never actually used an old radio like that. Like there were some laying around that nobody used anymore and I kind of played with them as a kid, but I’m right on the cusp of not knowing how to use one.

        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.
