Before anything else, let’s first talk about the legality of doing this. I haven’t looked into it that much, but I know it isn’t permitted to broadcast on DAB+ frequensies if you don’t have a license or permit.

Here’s how you can set it up for yourself:

1: Run this command

➜  ~ ssh-keygen -r $hostname

2: ??? \ 3: Profit!

In all seriousness: you’re now going to see the records you need to add that are specific to the server you ran the command on. It looks something like this:
