When I was a kid, in my Mexican hometown I didn't have the chance to use BBS, Teletext or Ham radio. I read about those in books or magazines, but never actually played with any.

I could connect with a friend in the same city via phone modem to play games or to transmit files and later to the Internet at the huge speed of 56 kbps.

Radio broadcasting was always interesting for me, I started a college radio station in 2008, and we moved all the content to Internet radio and an emerging Podcast system. Was a nice hobbie, but nothing really reached farther than school.

In those years connection was limited by hours or data transmitted. Renting a server was many times more expensive, or you'd have to set up your own server. Now you have almost unlimited data in your home, or a decent amount in any city and highway in some countries.

'Sadly' today is really simple to rent a VPS for 5 USD/month, storing many gigabytes of audio, video, text or any digital text and serve it 24/7 on many protocols and formats, say HTTPS, RSS or any other.

With a mobile phone you can play almost any format, get a data plan in many main cities for as few as 10 USD/month or even look for a public WiFi Hotspot to connect to any end point in the Internet. A lot has changed for good.

About 5 years ago I heard about Outernet (renamed later to Othernet), and I was intrigued again. The are (were?) renting a satellite slot to broadcast digital signals with files, Wikipedia among other cultural content, to a whole continent or to USA and northern Mexico.

You need to buy specialized hardware or adapt a Raspberry Pi, buy a satellite receiver, and pay some amount of electricity. Then in places without Internet you can have a WiFi repeating all the info received from the satellite.

In 2021 I learned about Gemini and SmolNet. The idea and philosophy behind is pretty cool.

Perhaps streaming selected smol content on a Ham radio transmitter would make sense? Makes me wonder.

It's extremely inconvenient, unlike the current alternative, slow, expensive and geographically limited. At least an interesting engineering solution for a problem we don't have in big cities anymore.

I have been wondering this for a few months now. I have seen a Modern Rogue video where they had a HAM specialist on who demonstrated sending data using radio. That made me interested in using GMRS to try to send gemlogs to my father across town.

I've been trying to learn more on SDRs in general, and specifically Airspy, to hopefully help get a setup where I can use my phone to send him data, however I've only just really got into it so far. He's gotten way more into using SDRs to talk to people around the world, so when I get my tech license I'd like to look into doing it on HAM as well. I don't know enough about MURS, the only people that use it around me are Knott's Berry Farm's chicken restaurant, but it might be good to look at as well.

Some acronyms written out for anyone who doesn't want to go look them up:

GMRS - General Mobile Radio Service, one of the amateur radio bands, overlaps with FRS - Family Radio Service

SDR - Software Defined Radio - Essentially you took some of the hardware components of a radio, and made them into a software interface on a computer. Lot's of added functionality.

MURS - Multi-use Radio Service

There are ways of sending e-mail

This is super interesting, have you tried out Othernet at all? Seems like they are suspended until next spring. It would be interesting to try out.

BTW, I forgot to paste a link about Ham radio in 2020 and it's decline on younger generations
