It’s not much but it’s a network nexus with an insane number of backbone links for redundancy.

I’ve created a portal in bash to allow HF access to emergency web content, here’s a demo of it going 900km loading HN.

This is super cool. Do you have more details about hardware, software and radio interface?

my pactor modem doesn't do vara or ardop, are those more common around there? I do know that winlink does that in software modems (and iirc Vara costs money), but without a dedicated and maintained laptop or computer digital modes are fairly awful. Having/using hardware makes stuff like emcom less painful and require less attention.
