there has existed for somehing like 35 years an analogue modem for 27MHZ, 142MHZ licenced and unlicensed. It's just a little PCB you solder to your mike / speaker points. There are multiple private 24/7 uplinks around the world. so you can mail and surf as you would normally, but slow. Around 2K baud, So try to sync your block chain on that.

As a post apocalyptic internet it's fine.

This sounds really interesting. Any chance on a link to more info?

Here you go, it's called a TNC: http://www.coolcircuit.com/gadgets/category/ham-radio/ There are 100+ pages about them.

Apparently there are also micro processor versions now...

BTW there are also free HAM satellite repeters for voice and data: http://www.amsat.org/amsat-new/index.php
