Solarpunk. Ultra-low-powered whisper radio telecommunications across the globe. People baking ICs in their basements. Hardware that can be repaired for decades, disaster-proof Operating Systems. Text-only protocols, heavily immune to the ad industry. What a time to be alive!

I wonder if some of the nerdiest corners of the internet from nowadays do not make the exciting 90s pale in comparison (all this looks like aspects of a potential renaissance).

As hobbies, they all sound amazing. Even though, or perhaps due to their apparent futility. "Secession from the broadcast" and "the knowledge" come to mind. A possibility, among many others.

ICs are not the problem, this can be decoded with a soundcard within the pc... usually the antennas are more problematic, atleast for urban areas, because you need 2x5.5m long dipole to use those frequencies (13mhz), so doing it in dense, urban enviroments is hard (unless you have roof access).

Otherwise, with lora and a lot shorter ranges, you can create mesh communication networks easily, with $20-$30 of hardware (already assembled) - eg. https://meshtastic.org/
