  • The last couple major power failures we've had in my area, information was by far the most difficult thing to come by.

    The power goes out, and shortly thereafter so does cable internet. My UPS usually keeps my cable box up longer than the service itself lasts. That puts everyone on the cell network, which is immediately overloaded. So the internet is essentially worthless during most hours.

    FM radio stations are similarly worthless. I remember a power outage last winter where there was going to be a press conference, I think the governor was going to talk about something...couldn't get coverage. The local FM station was up and running, they were broadcasting just fine, but they were trying to patch into the press conference via Facebook, and the internet wasn't up to it. They apparently don't have their own radio uplinks anymore.

    The local television station would have been more help...if I could get an antenna high enough to hear it.

    And during normal business hours most broadcast FM stations are IHeartRadio transmitting the same 20 songs intercut with the same 90,000 advertisements. Or broadcasting The Two removed Named Chris show three times a day.

  • Every phone I had that did this also used the wired headphone cable as an antenna. Personally I do like Bluetooth on the go (for casual listening only), so I'm not actually sure it would be usable unless the phone had a separate antenna.

  • FM access would cut down on mobile data usage… up-to-the-minute weather reports and automated alerts… are broadcasted at 162.400, which means you need specialized radios to pick up the stations… maybe an external antenna could use the shield or one of the pins on the phone’s charging port, or wired USB-C headphones and 3.5mm adapters could be updated to work as antennas… There could also just be an adapter that connects to the phone and contains all the required hardware…

    What the fuck is this person smoking?

    • No idea?

      but to break the points apart a bit...

      FM access would cut down on mobile data usage

      FM radio is something like 54kHz. Simplisticly we can say that would be 54kbps... let's even say it's double that to account for overhead. so 108kbps. That's just about 1 GB/day. That's not really an amount that carriers sell anymore... Nor do people normally listen to music 24hours a day.

      up-to-the-minute weather reports and automated alerts

      Only if you're listening... and our phones do automated alerts already... as long as those systems are working. And considering that FM is a completely different well documented thing... it's worth keeping it around.

      are broadcasted at 162.400, which means you need specialized radios to pick up the stations…

      Nah, FM has been built into chipsets for well over a decade at this point. Most radios even still have them today. Just disconnected. But even if it wasn't available... Most phones at this point use RTL-SDR radios... software define radios means you can just program it to FM frequencies and it will work.

      maybe an external antenna could use the shield or one of the pins on the phone’s charging port, or wired USB-C headphones and 3.5mm adapters could be updated to work as antennas…

      Or even the wireless contacts for Qi charging and NFC... Just disable the radio app when these things are actually in use...

      There could also just be an adapter that connects to the phone and contains all the required hardware…

      No need, the vast majority of phones already have what you'd need. Just never connected/used by software for some reason.
