Can’t tell if your referring to jorn in relation to meme or why ‘jorn’ is so good.
Jorn is the Jindallee over the horizon radar network.
Not sure exactly how it works, but someone put up a big array of radar transmitters and receivers in the outback and it might use the HF band like Ham radio users use to bounce off the ionosphere to get returns.
Sad GAF Nomad noises. But to be fair, they’re not exactly in production any more. But I reckon we could build a few factories.
